  The postglacial relative sea level history is reconstructed in four areas of mid- and inner Oslofjorden in southeast Norway. The reconstructions are based on radiocarbon-dated raised shoreline levels from 42 sites, mainly isolation basins, and limiting ages from four lakes above the marine limit. All localities are located inside the Younger Dryas Ra moraine and experienced high rates of glacio-isostatic crustal uplift since deglaciation, by far outpacing the eustatic sea level rise and resulting in continuous regional shoreline regression up until today. A postglacial shoreline diagram is constructed, which can be used to derive relative sea-level curves and to date raised shoreline elevations along the fjord. Reconstruction of shoreline isobases within the study area show that their orientation has shifted more than 60° from the deglaciation until present. The shift has been accounted for in the shoreline reconstructions and is likely showing that the initial postglacial uplift was largely influenced by the geometry and load of the Younger Dryas ice sheet in south Norway. We use the tilt of the oldest, well-dated shoreline levels to date a series of substages during northwards ice margin recession in southeast Norway. The results show that the ice margin retreated from the Ra moraine around 11.6 ka and provide the following ages for subsequent substages: Ås 11.45 ka, Ski 11.4 ka, Aker 11.25 ka, Hauerseter 10.9 ka, Dal 10.8 ka and Minnesund 10.6 ka. The deglaciation and shoreline chronologies are combined to produce regional palaeogeographical maps covering stages of deglaciation and land emergence.

  A new Standard Pollen Diagram for southeastern Norway (c.f. Hafsten 1956) is compiled from 60 local pollen diagrams supplied with 229 14C-dates. Eight regional pollen assemblage zones describe the vegetation history for the last 12 300 years (all dates in calibrated years b2ka). The Younger Dryas vegetation was an arctic tundra with pioneer herbs and low bushes. At the onset of the Preboreal summer thermal maximum ca. 11 400 years ago, a birch Betula spp. woodland was established together with pioneers such as sea buckthorn Hippophäe rhamnoides. About thousand years later pine Pinus sylvestris and hazel Corylus avellana expanded. At the start of the Holcene ecological optimum ca. 9 200 years ago, alder Alnus spp. and elm Ulmus glabra expanded, followed by the expansion of oak Quercus robur and later lime Tilia cordata and ash Fraxinus excelsior ca. 7 600 years ago. Together they formed the thermophilous mixed oak forests of mid-Holocene, where the occurrence of mistletoe Viscum album, ivy Hedera helix, and holly Ilex aquifolium indicate a longer growing season with favorable summer and winter temperatures. Approximately 6 000 years ago the first traces of agriculture are recorded in the southern part of the region. Indicators of grazing / introduction of livestock occur first, followed by cereal-growing (barley Hordeum spp., oats Avena sativa, and wheat Triticum spp.) at the transition Mesolithicum – Neolithicum. Some other agricultural indicators such as weeds, hemp/hops Cannabis/Humulus, and linen Linum are mentioned. Rye Secale was introduced ca. 3 200 years ago. Agriculture increased during Bronze Age, and expanded at the beginning of the Iron Age. This had an increasing influence on the forest ecosystems. The last trees to expand were Norway spruce Picea abies and beach Fagus sylvatica. The latter has mainly been established in Vestfold county, but occur sporadic further south along the coast. Spruce expanded a little earlier on the eastern side of the Oslofjord compared to the western side, Vestfold and southeastern Telemark, were the expansion occurred ca. 1 200 years ago. http://nhm2.uio.no/botanisk/nbf/blyttia/

  In this, the first of six volumes, the main results of the excavations which the University of Oslo carried out at Kaupang 1998–2003 are presented. A completely new picture is put forward of the port that Ohthere (Óttarr) visited in c. 890 AD. It is argued that Kaupang was one of three towns that were founded in south-west Scandinavia around the year 800. Kaupang was founded in the power centre Skiringssal, which for decades had been ruled by the Ynglings – the legendary Norwegian royal lineage. The founding was probably initiated by the King of the Danes – the dominant political actor in south-west Scandinavia at the time. Kaupang is shown to have had several of the features revealed in Birka, Hedeby and Ribe – i.e., a compact permanent settlement, divided into small plots, each with a dwelling. The town could have had 400-800 inhabitants. Substantial traces of trade and craftwork are proof of the main areas of occupation. Advanced geo- and environmental-archaeological analyses, published here, have played an important role in interpreting the finds. Documentary sources indicate that Skiringssal was an important royal seat in the 700s and 800s. These sources are put together with the archaeological and toponymical sources which, united, show a centre of power with a clear likeness to similar places in Denmark and Sweden, so called “central places”. A hall or sal building, presumably the Skirings-sal itself, has been excavated at Huseby, near Kaupang. Nearby, a thing site was situated by a holy lake. In this, the Yngling kings’ centre of power, to which many people came to attend thing meetings and sacrificial feasts, the town Kaupang was founded. The transition to Christian religious practices in Viken in the middle of the 10th century and the consequent demise of pagan cult activities in Skiringssal was probably a key factor in the abandonment of Kaupang at that time. In nine of the book’s 20 chapters, the excavations’ finds, analyses and results are presented. In three chapters, 200 years of research on Kaupang and Skiringssal are summarised, while in the remaining eight chapters an endeavour is made to re-establish the holistic approach to Skiringssal which dominated research in the 19th and early 20th century.

Bind lI og Bind Ill inneholder beskrivelser av de enkelte lokalitetene. E 18 Brunlanesprosjektet ble etablert 1. mai 2007 og avsluttet 31. juli 2011. I 2007 og 2008 undersøkte prosjektet ti tidligmesolittiske boplasser, en senneolittisk boplass og en jorbruks­lokalitet fra eldre jernalder. Undersøkelsene foregikk i to delparseller for nye E 18 gjennom Vestfold og Telemark, der tiltakshaver var Statens vegvesen, Region sør.
