    25 år senare: en nyinventering av keramiken på Ajvide2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis examines a sample of Pitted Ware pottery from the Gotlandic site of Ajvide in regard to the spatial and temporal relationship of the shards. Ajvide Stone Age site have been extensively excavated over the past 25 years and the most recent analysis of pottery was carried out by Inger Österholm in 1987 and new analyses of the material are therefore greatly needed. Pottery from three sample areas was analysed in regard to their distribution, decoration, fragmentation, part of pot and quality of the goods. To analyse the material in a contextual way a multivariate statistical analysis called correspondence analysis was used. Two areas denominated “dark areas”, which Österholm defined previously, as possible ritual sites, and one reference area with mixed material were chosen for the analysis. By including two of these “dark areas” the study also examine if similarities or differences could be seen among the shard distribution how these areas have been defined and possibly re-defined.

    A Metagenomics Transect into the Deepest Point of the Baltic Sea Reveals Clear Stratification of Microbial Functional Capacities2013In: PLoS ONE, ISSN 1932-6203, Vol. 8, no 9, e74983- p.Article in journal (Refereed)
    Abstract [en]

    The Baltic Sea is characterized by hyposaline surface waters, hypoxic and anoxic deep waters and sediments. These conditions, which in turn lead to a steep oxygen gradient, are particularly evident at Landsort Deep in the Baltic Proper. Given these substantial differences in environmental parameters at Landsort Deep, we performed a metagenomic census spanning surface to sediment to establish whether the microbial communities at this site are as stratified as the physical environment. We report strong stratification across a depth transect for both functional capacity and taxonomic affiliation, with functional capacity corresponding most closely to key environmental parameters of oxygen, salinity and temperature. We report similarities in functional capacity between the hypoxic community and hadal zone communities, underscoring the substantial degree of eutrophication in the Baltic Proper. Reconstruction of the nitrogen cycle at Landsort deep shows potential for syntrophy between archaeal ammonium oxidizers and bacterial denitrification at anoxic depths, while anaerobic ammonium oxidation genes are absent, despite substantial ammonium levels below the chemocline. Our census also reveals enrichment in genetic prerequisites for a copiotrophic lifestyle and resistance mechanisms reflecting adaptation to prevalent eutrophic conditions and the accumulation of environmental pollutants resulting from ongoing anthropogenic pressures in the Baltic Sea.

    A small separate fatherland of our own: regional history writing and regional identity on islands in the Baltic Sea2014In: Island Studies Journal, ISSN 1715-2593, Vol. 9, no 1, 135-154 p.Article in journal (Refereed)
    Abstract [en]

    Gotland, Åland, Saaremaa, Hiiumaa and Bornholm are five islands in the Baltic Sea which constitute, or have until recently constituted, provinces or counties. Combining perspectives from the fields of island studies and history, this article investigates how regional history writing has contributed to the formation of regional identity on each island since the year 1800. The special geographic situation of the islands somewhat secluded from the mainland but also connected to important waterways has provided their inhabitants with shared historical experiences. Due to varying geographic and historical circumstances, the relationship between regional and national identity is however different on each island. While regional history writing has often aimed at integrating the island into the nation state, it has on Åland in the 20th century been used to portray its inhabitants as a separate nation.

    A Viking Period Metalworking Hoard from Alvena in Mästerby parish, Gotland2011In: Fornvännen, ISSN 0015-7813, Vol. 3, 242-245 p.Article in journal (Other academic)
    Abstract [en]

    -This paper presents a newly found but ploughed-out hoard of cast bronze objects from Mästerby parish Gotland. The objects - 5 sword pommels and 16 pendants - were found by metal detector can be dated to the late 10th Century AD. The hoard is of particular interest from an archaeometallurgical point of view since none of the objects appears to have been finished off and made ready for use. Hence it is good a clue to Gotlandic non-ferrous metalworking in the Viking Period.

    A world apart?: An Investigation of the Roman Influence on Rural Settlements in Britain compared to Sweden during the Roman Iron Age2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This is a study of the Roman Iron Age in both Sweden and Britain but with a focus on the latter. The study includes a comparative analysis of selected goods in the material culture at a number of different sites in Sweden and Britain in the aim of understanding the extent of the Roman influence at these sites. The aims of the essay is to investigate if we can notice similarities between the Swedish and British setting and thereby draw conclusions regarding the Roman influence or lack of it in the Rural setting of Britain as well as the chosen settlements in Sweden. Was the Romanization of Britain for everyone or was it reserved for the elite?

    A worth of their own: on Gotland in the Baltic Sea, and its 12th-century coinage2010In: Medieval Archaeology, ISSN 0076-6097, Vol. 54, 158-181 p.Article in journal (Refereed)
    Abstract [en]

    In about AD 1140, the island of Gotland initiated what was to become one of the most influential coinages of the medieval Baltic Sea area. This was part of a strategy to meet the impact and pressure from the world outside in a period characterised by large-scale political and ideological changes. In this situation, old and new networks were important to maintain autonomy from those aiming for dominance over the island. The coins, with an independent weight standard and an iconography inspired by NW German and Frisian coins, were one way of attracting partners to the island’s main harbour, where its inhabitants could maintain control and trading peace.

    Coins incorporate in them the dimensions of object, text and picture. A historical archaeology of coins needs not only focus on large-scale perspectives and formal power, but must also give weight to the archaeological context, the life biography of the coins and the social negotiations behind their production and use. Thus intention and reality, symbolism and social practice may be studied to find openings to the stories behind the objects. The different dimensions of the coins together with historical sources give away plenty of information on several levels: about the networks, ideological framework, artisanship and changing loyalties of this time and area.

    Accompanying the stone ships: circular stone settings in relation to the Gotlandic ship settings2012In: N-TAG ten: proceedings of the 10th Nordic TAG conference at Stiklestad, Norway 2009 / [ed] Ragnhild Berge, Marek E. Jasinski, Kalle Sognnes, Oxford: Archaeopress, 2012, 59-70 p.Chapter in book (Refereed)
    Abstract [en]

    The ship is the dominant depiction of the visual Scandinavian Bronze Age. It appears in rock art, on bronze artefacts and as stone monuments. When studying the ships on rocks and bronzes one feature commonly appears in relation to it: a round or circular motif, which most often is interpreted as the sun. Geographically rock art is concentrated to the mainland of southern Sweden and Norway. The bronze artefacts with depictions of ships on the other hand, are distributed mainly to Denmark. Gotland on the other hand, located in the Baltic Sea, with a rich Bronze Age landscape, lack prominent rock art panels or ships depicted on bronze artefacts. Instead the ship appears in another form. Gotland holds today c. 380 prehistoric remains referred to as stone ship settings. A more exhaustive study of the stone ships visualise large local variations. One phenomenon appearing when visiting ship setting sites is a circular stone setting of tightly placed stones. In this paper this circular phenomenon is discussed in comparison with the other two media where the ship appears in relation to a circular feature: Rocks and Bronzes!

    Agkärr2015Report (Other academic)
    Abstract [sv]

    Denna rapport behandlar naturtypen agkärr, en naturtyp som ingår i EU:s art- och habitatdirektiv. Syftet med framtagandet av rapproten har varit att ta fram uppföljningsbara kriterier för gynnsam bevarandestatus på lokal och biogeografisk nivå, utveckla en kvalitetstestad lista över lämpliga typiska arter samt att ta fram en praktisk användbar definition av gränsdragning mellan agkärr och rikkärr. Inledningsvis beskrivs naturtypens utbredning idag och historiskt, förutsättningar för dess etablering, hydrologiska förhållanden, växt- och djurliv i naturtypen samt faktorer som kan hota naturtypen. Totalt fältundersöktes åtta områden på Öland. Tre av dessa hade inte förutsättningar för att kvalificera för utpekande till naturtypen agkärr, då arten ag helt saknades i dessa områden. På Gotland fältundersöktes sex områden.

    Abstract [sv]

    STIGAR, VÄGAR OCH VATTENLEDER är nödvändigaför alla samhällen. Det är därför naturligt att vägaroch vägsystem ska diskuteras mom historievetenskaperna.För Roma-Kolk-projektet1 som lagt tyngdpunktenpå det medeltida Roma klosters ekonomiska grundvalar,är naturligtvis transpordederna för förnödenheteroch pengar till klostret av avgörande intresse. Emellertidgår det inte att bryta ut Roma klosters vägar frånvägarna före och efter klostrets existens. Vägsystemetkring klostret har rimligtvis en lång förhistoria, särskiltmed tanke på att Gutnaltinget, Gotlands huvudtingunder vikingatid och äldre medeltid, sannolikt har haftsitt säte i Romaområdet. Tingsbesökarna måste ha haftupptrampade vägar att färdas på. Med klostrets stängningoch etableringen av landshövdingehostället Romakungsgård fick vägarna nya funktioner. Andra vägar försvann,helt eller delvis. Vi har valt att undersöka vägarnai ett 1500-årigt perspektiv.

    Almedalsveckan: en studie i hur ett av Sveriges största politiska arrangemang har tagit form2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Politicians Week in Visby has since the late 1960s developed to be a fairly unique concept in Swedish politics, which even in recent years has begun to be exported to other countries in Europe. Curiosity and interest around the arrangement of activities and actors have in the past decade become increasingly both nationally and internationally. The purpose of this study has therefore been to find out how “Almedalsveckan” as a political arrangement emerged and developed. The question that the study mainly tries to answer is how “Almedalsveckan” became a concept of the open democratic meeting between politicians, citizens, journalists and various organizations in the Swedish society. To find out, mainly newspaper articles from the Gotland newspapers has been used, as well as an interview with the former municipal politician Jan Lundgren (s) has been made. Source material has also been obtained from the Library of Almedalen in the Gotlandica department, “Almedalsveckan” official website, Gotland Tourist, SCB and SIKA. The investigation has been defined to include the election-years for the period 1968 - 2009 but other years have also been used to see how political participation has been in non-election year and in 2009 to root development at the present time. The results from the survey show how the arrangement evolved to this stage as a meeting place for political debate in which politicians, citizens, journalists and various organizations engaged in informal conversations.

    An island in the middle of an island: On cult, laws and authority in Viking Age Gotland2009In: From Ephesos to Dalecarlia: Reflections on body, space and time in medieval and early modern Europe, Stockholm: Statens historiska museum , 2009, 101-118 p.Chapter in book (Other academic)
    Abstract [en]

    The present-day small village of Roma on Gotland in the Baltic Sea was the physical and symbolic centre of the island in the Iron Age and into Medieval times. The Cistercian monastery and the meeting place of the island’s assembly, the All-thing, two well-known features of medieval Roma, have often been taken as indications of an egalitarian and non-stratified society on Gotland during the Viking Age and Middle Ages. It is here proposed, however, that an older Iron Age cult site at Roma eventually came under the control of a chieftain or major landowner who introduced Christianity, founded a monastery and inaugurated the thing in Roma in Viking or early medieval times, just as his equals did elsewhere in Scandinavia. While the later medieval thing was probably located near the monastery, an alternative site on a small island is suggested for the older All-thing.

    An Optimal Foraging Perspective on Early Holocene Human Prey Choice on Gotland: Affluence or Starvation?2012Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The Optimal Foraging Theory, rooted in the processual archaeology, uses a measuring methodology where the foraging strategy that gives the highest payoff measured as the highest ratio of energy gain per time unit is analysed (Mac Arthur & Pianca 1966, Emlen 1966). The theory is a branch of evolutionary ecology why much attention is paid to the interdependence of humans and preys and environmental conditions caused by climatologically and geographical changes or by overexploitation or other changes caused by humans. The analysis of Early Mesolithic pioneers onGotland, who settle in a transforming landscape, leaves indications of a Maglemose culture origin, probably from flooded original settlements in the south/southwest Baltic basin. The pioneers have to adapt to a seal-hunting economy dominated by grey seal which give the best cost-benefit outcome as big terrestrial mammals are missing and only mountain hare is available. The diet is narrow and there is a great risk for deficiency diseases as well as for acquiring hypervitaminosis and osteoporosis caused by excess of seal food.

    There is a hiatus c. 5000-4500 BC in the archaeological records on Gotland and the south-western Baltic region, and the master thesis hypothesises that Littorina Transgression I with a severe cold dip called the “8.2 ka BP cold event” has a delayed, but such a severe impact also on fauna and flora on Gotland, that the ecological system is destroyed. The possibility for humans to survive in a sustainable society is questionable. The extremely cold winters during this c. 400 years cold event, with glaciers moving southwards, delayed the blooming season, diminished the harvest and changed both flora and fauna. When the ecological niche for the grey seal is destroyed with flooded beaches close to the pioneers, human overexploitation is reinforced. With a diminishing population of mountain hare, which eventually gets extinct at the end of the Mesolithic, there are no alternatives but some birds and fish, hard to catch. Probably the pioneers abandon Gotland or move to a higher level on Gotland but no records are yet found why the period is called a hiatus. Extinction is the worst scenario or survival in such a small number that a sustainable society is lost. If so, new population groups repopulatedGotlandafter the Littorina transgressions. The origin is still unknown of the Pitted-ware and Funnelbeaker cultures that are populating Gotland after the transgressions. This master thesis can not confirm an affluent life style but rather a suffering starving society flooded by Littorina transgressions and struggling with the severe cold, caused by the “8.2 ka cold event” that makes the environmental conditions even worse. The subsistence economy is successively destroyed which probably causes the hiatus in archaeological records. The Littorina Transgression I with the “8.2 cold event” and the lack of terrestrial big animals are bottle necks.

    In this paper, we discuss variations seen in the ornamentation and modes of manufacturingpottery from the end of the mid-Neolithic 4600–4300 BP on the Island of Gotland in theBaltic Sea. The Pitted Ware cultural groups have been discussed as a western influence from the Swedishmainland, but the aDNA on skeletal remains point to eastern influences. We analyse and discusspottery from the well-investigated Ajvide Pitted Ware site and what these variations mean interm of intra- and inter-island relationships, ethnicity and change, and we suggest the developmentof what could be described as a hybrid culture.

    Approaching the Gotlandic Bronze Age from Sea: Future Possibilities from a Maritime Perspective2010In: Baltic Prehistoric Interactions and Transformations: the Neolithic to the Bronze Age / [ed] Helene Martinsson-Wallin, Visby: Gotland university , 2010, 89-109 p.Chapter in book (Other academic)
    Abstract [en]

    Although the Bronze Age is a period when travel and interaction over large areas has been intensively discussed, not least in the Baltic Sea, the role of seafaring and maritime knowledge in the society has seldom been considered. Maritime archaeology has been viewed as peripheral in the archaeological discussion. The sea has been considered as a boundary when interpreting landscapes. More recently a maritime cultural landscape, a seascape, has developed in the archaeological discourse. In this paper I aim to apply and discuss such perspectives in the Baltic Sea region during the Bronze Age, with particular focus on the Gotlandic stone ship settings and their place in the secular and ritual landscape/seascape.

    "Finally, it can be said that the significance of picture stones throughout the centuries has undoubtedly been multifunctional and changing – as territorial marking, a memorial, preserver of oral tradition, burial site and religiously charged artefact. The picture stones have played a key role in the Gotlandic society in the late Iron Age and early Medieval Period, they were a focal point for social and ideological communication between the people of their time."

    This thesis discusses the differences between how archaeologists and cultural geographerdescribe the early Iron Age on Gotland. What objects, phenomenon and arguments do theyuse to describe this period. Four publications have been analysed in this study, two written byarchaeologists, two by geographers.The differences in how they describe the period in question are significant. Both disciplinesgive a very fragmentary description of the older Iron Age in Gotland.

    Abstract [en]

    Report over the 2014 re-excavation of soil from the cave Stora Förvar on the island of Stora Karlsö, Gotland, Sweden. In total 6 sqm were excavated and finds ranging from the Neolithic up until the early modern era was recovered. The soil was most likely removed from the cave in 1888. Among the more notable finds were flint hand drills, fragments of Viking-period casting moulds (for an oval brooch, Type P 25), a copper-alloy tool (most likely for glas bead making), iron fittings from a cog and a medieval Gotlandic coin (Örtug/Gote, 15th Century). The Viking-period finds strongly indicates that the cave was utilized as a workshop area in the early Viking Period (c. 800-850 AD). Among the crafts performed in the cave were iron smithing, bronze casting, antler- and bone-, stone- and glass working.

    Artefacts and bone patterns in stone ship settings on Gotland2012Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is an attempt to gather and discuss the archaeological and osteological results that has been found in stone ship settings on Gotland. The bone material from five ship settings, one stone setting and a cairn from the bronze age complex at Rannarve in Klinte parish on Gotland has been osteologically analysed during this study to further expand the osteological results that are available from ship settings on Gotland and try to interpret this site. The aim is to try to find what artefacts and bone patterns that can be distinguished from the material found within ship settings. What patterns can be seen in artefacts, age, sex and burial contexts that has been found in ship settings? What are the most common patterns?

    Att vara eller icke vara?: en diskussion om kulthusens existens på Gotland2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is to find evidence if cult houses existed on Gotland during the Bronze Age. The cult house is a common term in modern Bronze Age archaeology and the general definitions of cult house are discussed and why cult houses seem to be absent on Gotland. In this thesis the cult house are discussed as a phenomenon, and the possibilities to find Bronze Age cult houses on Gotland are evaluated by making comparisons between Gotland houses with already defined cult houses from the Swedish mainland. Some known cult houses are presented in more detail as case studies, together with house remains on Gotland which could have potential to be defined as cult houses.

    Kring 1900 hade Gotland blivit en international turistdestination. Den största gruppen utländska turister kom från Tyskland. Artikeln undersöker med hjälp av tyskspråkiga publikationer från 1800-talet varför Gotland hade blivit en intressant turistdestination just för tyska turister, vad det var som attraherade just denna grupp, vem det var som konstruerade denna attraktiva bild av Gotland i Tyskland under 1800-talet.

    Axelssönerna (Tott): Ett ekonomiskt imperium inom gränsadeln i 1400-talets Norden2010Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay explores the economical and social paradigms surrounding one of the most influential

    Nordic border dynastic noble families in the second half of the fifteenth century - the Axelsson

    Totts. How mercantile possibilities and opportunities offered to them, reflected on their political

    actions and social bands. The Axelsson brothers of the Tott Dynasty would become of one of the

    most powerful noble families within the Nordic Union between 1444 och 1487.

    Axel Pedersen (Tott) would through well chosen marriage alliances into the noble families of both

    Denmark and Sweden, and with political prowess lay the foundation for one of the most dynamic

    family empires of the fifteenth century. In the year 1442, the Axelsson brothers swore loyalty to

    each other; to protect and defend their mercantile and economical interests in Denmark and

    Sweden. They would eventually control the trading routes in the border areas of the Union, and by

    exploiting the political chaos within the Union they would gain access and influence to the land

    trading routes for export and import within the Union and the shipping export routes in the Baltic

    Sea allowing them access to the Russian market through Finland and Estonia.

    The island of Gotland, with its tactical and important geographical position in the Baltic Sea

    became the key to the Nordic Union. Olof Axelsson (Tott) sailing under the Danish flag took

    possession of Gotland in 1449. Although technically a part of the Danish kingdom, in practice the

    island would remain independent and under the control of the Axelsson brothers until 1487 when

    the last surviving brother, Sir Ivar relinquished his rights to Gotland in favor of the Danish

    monarch, King Hans.

    The Axelsson brothers (Tott) would hold the key to The Nordic Union for almost four decades.

    Thus controlling the future of the union within the family by marriage, by political associations

    within and outside of the Union and most importantly by creating an economical empire based on

    personal family politics and border gentry aspirations.

    Abstract [en]

    Innovator Håkan Berndtsson has developed an idea for a new spin on cutlery for small children to start learning to feed themselves. The idea is investigated in this graduation project to create an overall concept of a dinner set for children. The focus lies on developing Berndtssons cutlery were knife, fork and spoon is included. This is accomplished by applying the design methodology.

    A common problem with many types of cutlery for children today is that the children have difficulty getting a grip that is easy to use for bringing food to the mouth. This results in a lot of wasted food and messy meals. The kids lose their patience when they encounter too much difficulty with the cutlery and they will ingest less food with each bite.

    The target group for the project were children in the beginning to learn how to eat themselves with different meal gear. This is done in a span of about one to three years depending on the child's individual development.

    The solution to the problem consists of a grip that combines a power and precision grip for the fork and spoon.

    With this grip the child can without further effort bring the food to the mouth with precision. The knife has a different function and is therefore designed for this, namely, cutting and squashing food. Overall suggestions for the solutions to the mug, plate and bowl has been made. The idea for the cup is that it is able to develop and change its functions as the child itself develops, by replacing parts of the mug. The plate and bowl can be inserted in one another and therefore create a lunchbox that can ie. be included in excursion.

    The result consists of three cutleries, a fork, a spoon and a knife where all of the grips are developed through the use of ergonomic studies and in close collaboration with a pre-school. The development of the remaining parts of the dinner set was stopped after revising the project at the end of the “idea generation”-process. The result has an idiom that consists of a pervading animal theme that binds together the cutlery to unified concept. The theme of animals is relatively gender neutral and are pedagogically suited for younger children. The cutlery grip is composed of plastic with the eating part of stainless steel.

    Barshalder 1: A cemetery in Grötlingbo and Fide parishes, Gotland, Sweden, c. AD 1-1100. Excavations and finds 1826-19712003Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The prehistoric cemetery of Barshalder is located along the main road on the boundary between Grötlingbo and Fide parishes, near the southern end of the island of Gotland in the Baltic Sea. The cemetery was used from c. AD 1-1100.

    The level of publication in Swedish archaeology of the first millennium AD is low compared to, for instance, the British and German examples. Gotland’s rich Iron Age cemeteries have long been intensively excavated, but few have received monographic treatment. This publication is intended to begin filling this gap and to raise the empirical level of the field. It also aims to make explicit and test the often somewhat intuitively conceived results of much previous research. The analyses deal mainly with the Migration (AD 375–540), Vendel (AD 520–790) and Late Viking (AD 1000–1150) Periods.

    The following lines of inquiry have been prioritised.

    1. Landscape history, i.e. placing the cemetery in a landscape-historical context. (Vol. 1, section 2.2.6)

    2. Migration Period typochronology, i.e. the study of change in the grave goods. (Vol. 2, chapter 2)

    3. Social roles: gender, age and status. (Vol. 2, chapter 3)

    4. Religious identity in the 11th century, i.e. the study of religious indicators in mortuary customs and grave goods, with particular emphasis on the relationship between Scandinavian paganism and Christianity.. (Vol. 2, chapter 4)

    Barshalder is found to have functioned as a central cemetery for the surrounding area, located on peripheral land far away from contemporary settlement, yet placed on a main road along the coast for maximum visibility and possibly near a harbour. Computer supported correspondence analysis and seriation are used to study the gender attributes among the grave goods and the chronology of the burials. New methodology is developed to distinguish gender-neutral attributes from transgressed gender attributes. Sub-gender grouping due to age and status is explored. An independent modern chronology system with rigorous type definitions is established for the Migration Period of Gotland. Recently published chronology systems for the Vendel and Viking Periods are critically reviewed, tested and modified to produce more solid models. Social stratification is studied through burial wealth with a quantitative method, and the results are tested through juxtaposition with several other data types.

    The Late Viking Period graves of the late 10th and 11th centuries are studied in relation to the contemporary Christian graves at the churchyards. They are found to be symbolically soft-spoken and unobtrusive, with all pagan attributes kept apart from the body in a space between the feet of the deceased and the end of the over-long inhumation trench. A small number of pagan reactionary graves with more forceful symbolism are however also identified. The distribution of different 11th century cemetery types across the island is used to interpret the period’s confessional geography, the scale of social organisation and the degree of allegiance to western and eastern Christianity. 11th century society on Gotland is found to have been characterised by religious tolerance, by an absence of central organisation and by slow piecemeal Christianisation.

    Bebådelsebilder: Om bildbruk under medeltiden2010Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This thesis investigates the Annunciation motif and the use of images in a medieval socio-cultural context. There are almost 400 medieval images of the Annunciation from the period 1150–1550 in Sweden today. It is found in murals, baptismal fonts, paintings, wooden sculpture, stone reliefs, liturgical vessels, textile works and altarpieces. The aim of the thesis is to present this rich and varied material, and also to relate the images to the milieus where they were used and viewed as objects of cult, and to elucidate the historical situation in which they were used for communicative purposes.  It is argued that an “image-culture” perspective and a long-term investigation can reveal other aspects than a specific study, and that it is fruitful to equally emphasize the rhetoric of the image, the beholders part and the historical context. Hence the picture analysis is based on semiotics and rhetoric analysis of pictures and reception theory. With this point of departure the thesis addresses iconographic problems and shows that text as a source and explanation of historical image can be insufficient.

    The study shows that the figures’ gestures and body language, their contenace, is crucial for our understanding, and remains the most important mark of identification. The motif can be identified even with an angel without wings. The meaning of this universal picture could then be enlarged with specific attributes and symbols with a purpose to emphasize specific ideas. In context this elucidates bishopric, monastic as well as worldly use of imagery. The image context includes motifs from classical antiquity, references to the pious Christian worshiper, as well as symbolic staging of the Gospels and Christian faith. More expected is the biblical history. The motif can also be displayed alone, and thus it can be regarded as a sign. An important outcome is that the Annunciation not is used in legendary suites or in narratives of the Virgin Mary. Hence, the relationship between image and text is not uncomplicated. The thesis shows that people in the Middle Ages were fully aware of the use of pictures and skilfully used the rhetoric of the image.

    Bedömning av miljökvalitet i Gotlands kustvatten med utgångspunkt från mjukbottenfaunans sammansättning2007Report (Other academic)
    Abstract [sv]

    Den marina mjukbottenfaunans sammansättning är en av de parametrar som under en lång följd av år använts inom miljöövervakningen, både i Sverige och utomlands. Redan på 1920-talet utfördes standardiserade provtagningar av mjukbottenfauna på ett antal kustnära lokaler, bl.a. runt Gotland. De flesta av dessa provtagningsstationer kom senare att ingå i det nationella miljöövervakningsprogrammet (PMK) för mjukbottenfauna. När nu ett regionalt miljöövervakningsprogram med bottenfauna i Gotlands kustvatten initieras var målet att använda gamla provtagningsstationer i så stor utsträckning som möjligt. Därutöver valdes ett ytterligare antal provtagningsstationer ut för att studera de lokala förhållandena i några områden, nämligen Fårösund, Vägumeviken, Burgsviken och Klinteviken.Mjukbottenfaunans sammansättning utgör ett mycket bra mått på ett vattenområdes miljöstatus, eftersom de bottenlevande organismerna är förhållandevis stationära och relativt långlivade och därmed väl speglar miljöförhållandena på platsen över en längre tid. Olikheter i miljökänslighet mellan olika bentiska taxa har utnyttjats till att ta fram ett s.k. bentiskt miljökvalitetsindex (Benthic Quality Index, BQI). Enligt EU.s vattendirektiv ska miljökvalitén i varje vattenområde klassas till någon av de fem klasserna Hög, God, Måttlig, Otillfredsställande och Dålig. Denna bedömning görs lämpligen med utgångspunkt från flera olika parametrar, bl.a. bottenfaunans sammansättning. Klassgränserna för en bedömning utifrån bottenfaunans sammansättning grundar sig på beräknade BQI-värden och är olika för olika vattenområden. Sedimentprover för kvantifiering av mjukbottenfauna togs i maj 2006 på totalt 31 stationer runt Gotland på djup mellan 6 och 100 m. Av dessa utgör 15 stycken "gamla" provtagningsstationer med tillgängliga bottenfaunadata från minst ett tillfälle under 1920-talet, 1970-talet eller 1980-talet. Utöver dessa .ordinarie. stationer valdes fyra områden ut för undersökning enligt ovan. Två av de 31 stationerna, som låg under haloklinen, uteslöts ur sammanställningarna, eftersom dessa inte kan anses som representativa för området i övrigt. De flesta stationerna hade sandiga sediment av olika beskaffenhet.Miljökvaliteten i de specialstuderade områdena Vägumeviken och Klinteviken bedömdes, med utgångspunkt från bottenfaunans sammansättning, som god, men till följd av förhållandevis höga tätheter av fjädermygglarver, med ett lågt miljöklassningsvärde, och låga tätheter av kräftdjur, med höga miljöklassningsvärden, gjordes bedömningen att vattenkvaliteten i Fårösunds är sämre. I det fjärde specialområdet Burgsviken togs, p.g.a. sedimentets beskaffenhet, för få prover för att en samlad bedömning av miljökvaliteten skulle kunna göras. Den samlade bedömningen av miljökvalitén utifrån bottenfaunans sammansättning på de 13 .gamla. provtagningsstationerna över haloklinen var att miljökvaliteten i Gotlands kustvatten är god. En jämförelse med äldre data från 1920-talet, 1970-talet och 1980-talet, antyder att miljökvaliteten är ungefär densamma som under 1920-talet, dvs. har varit god under hela denna period. Det genomsnittliga miljöindexvärdet på de undersökta stationerna har dock sjunkit kontinuerligt sedan början av 1980-talet, vilket är oroväckande. Det är därför viktigt att följa upp den fortsatta utvecklingen. Av vikt är också att bevaka den lokala miljökvaliteten i Fårösund och att försöka finna förklaringar till de låga indexvärden som noterades fr.a. i området närmast Fårösunds samhälle.

    Betydelsen av bortforsling av alger för rekrytering av plattfisk på Gotland2015Report (Other academic)
    Abstract [sv]

    Syftet med projektet var att utvärdera effekten av bortforsling av släke i vikar runt Gotlands kust på tätheten och storleken av juvenil piggvar och flundra som växer upp i denna typ av habitat. Juvenil piggvar och flundra samlades in med landvad i augusti 2014 och 2015 i totalt 19 områden där släke avlägsnades på nio stycken i delprojekt 1. I delprojekt 2 rensades en del av Lausviken medan en annan del av viken var orörd. I denna vik genomfördes flera provtagningar under säsongen medan endast en genomfördes på den regionala skalan i delprojekt 1. Förutom att fånga juvenil plattfisk togs även prover för att uppskatta syrehalt, turbiditet och organisk halt i sedimenten. Tätheten var generellt något högre i de rensade områdena för flundra 2015 i delprojekt 1 och för piggvar i slutet av säsongen i delprojekt 2 2014. Det är dock svårt att utesluta att andra faktorer påverkat de skillnader som uppstått då skillnaderna var små och variationen hög. Det senare speciellt för piggvar. Det fanns ingen skillnad i längd mellan rensade och ej rensade områden. I övrigt var den organiska halten lägre i de rensade områdena 2015 i delprojekt 1 och i delprojekt 2 hade halten minskat i den rensade delen och ökat i den ej rensade 2015 jämfört med året innan. Fler provtagningar behöver göras för att få en högre upplösning i tid och rum av miljövariablerna och för att säkerställa en eventuell trend i den organiska halten samt undersöka om resultaten för plattfisken blir tydligare

    Bevakning av häckningsframgången hos staren. Årsrapport för 20092010Report (Other academic)
    Abstract [sv]

    (1) Antal starar som skrider till häckning i bevakningsområdena och som således ligger till grund för analys av häckningens förlopp och produktionen av ungar samt möjliggör provtagning för miljögiftsanalyser är efter uppsättning av kompletteringsholkar i vissa av områdena nu helt tillfredsställande i Grimsö, Kvismaren, Tiveden, Svartedalen, Fleringe, Ottenby och Revinge. I Berg har antal häckningar minskat och om trenden inte vänder kan en kompletterande holkgrupp komma att behövas. För Tyresta behövs ett kompletterings- eller ersättningsområde. (2) Den genomsnittliga äggkullstorleken var hög 2009, men andelen flygga ungar var däremot låg i förhållande till vad som gällt under senare delen av 1990-talet och 2000-talet. Den var dock högre än många år under 1980-talet och första delen av 1990-talet. Långsiktigt över hela bevakningsperioden sedan början av 1980-talet finns inga övergripande negativa trender. (3) Äggläggningen startade 2009 tidigare än någonsin i flera av områdena och nytt tidighetsrekord slogs i en holk i Fleringe där första ägget lades 16 april. Starens häckningsstart och häckningsframgång är känsliga för vårens väder och därför indikatorer på effekter av klimatförändringar.
