Fluctuations of sediment accumulation rates in front of an Arctic delta in Greenland
An automated layer counting technique is developed to estimate the chronology of a marine sediment core and this technique is validated with Pb 210 chronology. The marine sediment core was sampled in front of the delta of Mittivakkat Glacier meltwater river in the Sermilik Fjord, SE Greenland, and is a proxy of the sediment delivery from a glacial drainage basin to a fjord. The estimated time series was based on automatic lamination detection (va…
At the edge
A multi-disciplinary study of settlement in north-east Greenland found that life in this High Arctic zone was actually favoured by the climate brought in by the Little Ice Age (fifteenth-nineteenth century). Extensive ice cover meant high mobility, and the rare polynyas - small patches of permanently open coastal water - provided destinations, like oases, where huge numbers of migrating marine mammals and birds congregated. One such place was Wal…
Coastal environments around Thule settlements in Northeast Greenland
Inuit have travelled to and settled in the coastal landscapes of Northeast Greenland for several longer periods during the latest ca. 4500 years. Most recently the Thule culture Inuit lived in the region from around 1400 until 1850 AD. The access to partly and periodically ice covered near coastal waters has been crucial to the primarily marine based subsistence strategy of the Thule Inuit culture, and their settlements are therefore found immedi…

Holocene evolution of a drowned melt-water valley in the Danish Wadden Sea
Cores from the salt marshes along the drowned melt-water valley of river Varde Å in the Danish Wadden Sea have been dated and analysed (litho- and biostratigraphically) to reconstruct the Holocene geomorphologic evolution and relative sea level history of the area. The analysed cores cover the total post-glacial transgression, and the reconstructed sea level curve represents the first unbroken curve of this kind from the Danish Wadden Sea, includ…
A late Holocene palaeoenvironmental record from Altona Bay, St. Croix, US Virgin Islands
Geografisk Tidsskrift, Danish Journal of Geography 108(2):59–70, 2008 A reconstruction of the palaeoenvironmental development of Altona Bay, St. Croix, northeastern Caribbean, has been made based on the sedimentological, geochemical and pollen analyses of a 1.83 m long vibracore. For chronological control, AMS 14C measurements were made at 5 levels downcore. The sedimentary sequence covers the last c. 4,700 years, containing both (mangrove) peat …
Holocene changes in climate and vegetation in the Ammassalik area, East Greenland, recorded in lake sediments and soil profiles
Geografisk Tidsskrift, Danish Journal of Geography 108(1):21–50, 2008 Holocene climatic, vegetational and environmental changes on the Ammassalik Island in SE Greenland (65.5 N and 37.5 W) have been studied in lake sediments and soil profiles. Based on the stratigraphy of sediments, geobiochemical characteristics, pollen and other biological proxies, a history of the land is outlined. The overall and continued climatic cooling during the Holocene…
Late Holocene sea-level changes and isostasy in western Denmark
Cores and exposed cliff sections in salt marshes around Ho Bugt, a tidal embayment in the northernmost part of the Danish Wadden Sea, were subjected to 14 C dating and litho- and biostratigraphical analyses to reconstruct paleoenvironmental changes and to establish a late Holocene relative sea-level history. Four stages in the late Holocene development of Ho Bugt can be identified: (1) groundwater-table rise and growth of basal peat (from at leas…
Total sediment budget of a transgressive barrier-spit, Skallingen, SW Denmark
Average sea-level rise in the northern part of the Danish Wadden Sea has been 1.3 mm a−1 during the last 100 years but during the last 25 years a rise of 4.2 mm a−1 was observed. Concurrent with the recent sea-level rise the Skallingen barrier spit has migrated landward by 3–5 m a−1. Long term sediment budgets for each of the morphological units involved in the migration are reviewed (e.g. onshore in the shore face +90.000 m3 a−1, longshore -641.…
Tidal and meteorological induced nutrient (N, P) dynamics in the micro-tidal Ho Bugt, Danish Wadden Sea
Tidal and meteorological induced variations in nutrient dynamics are important at all depth intervals in the Ho Bugt estuary. In the tidal channels, nitrate concentrations may vary ±20% and total nitrogen concentrations even more due to sedimentation/resuspension effects during the tidal cycle. On tidal flats, nutrient and carbon contents of the deposited material depend strongly on meteorological conditions and may vary 0.7% TC, 0.1% TN and 0.4%…
