Late-Holocene Atlantic bottom-water variability in Igaliku Fjord, South Greenland, reconstructed from foraminifera faunas
A high-resolution record of late-Holocene subsurface water-mass characteristics in outer Igaliku Fjord, South Greenland, is presented based on benthic foraminifera faunas from core PO 243–451 collected from a water depth of 304 m. Strati” cation with Atlantic water masses present in the lower part of the water-column is suggested to have prevailed during the last 3200 cal. years, except for a period referred to as the‘Mediaeval Warm Period’ (MWP)…

Late Holocene Changes in Precipitation and Hydrography Recorded in Marine Sediments from the Northeastern Caribbean Sea
We present a record of climate variability spanning the last 2000 years obtained from sediment cores retrieved south and west of Puerto Rico in the northeastern Caribbean Sea. The records include lithological and mineral magnetic parameters as well as planktonic foraminifer data. For chronostratigraphic control, AMS 14 C and 210 Pb/ 137 Cs measurements were made. Harmonic analysis of the values of the mineral magnetic parameters “saturation isoth…
Sediment Surface Geochemistry of Three Baltic Sea Deep Basins
Three deep basins were chosen for this study and the most recent changes that are reflected in the uppermost 15 to 35 cm are reported. The Gotland Basin, the largest continuous sedimentation basin in the southern Baltic Sea, was chosen for the present study. Simultaneously, a quite large basin, the North Central Baltic Basin was investigated and chemical data are reported for the first time. In the southern Baltic Sea the Bornholm Basin was inves…

Holocene history of the Baltic Sea as a background for assessing records of human impact in the sediments of the Gotland Basin
Sediment cores from the Gotland Basin were studied for their siliceous microfossil assemblages and organic carbon content to compare recent environmental changes in the Baltic Sea with its natural long-term history. Age models were constructed using 210 Pb, 137Cs and corrected and calibrated 14C dates. The transgression that marks the onset of the Ancylus Lake stage is recorded in the sediments as a small increase in organic carbon coinciding wit…
Sedmentation in the Central Baltic Sea as Viewed by Non-Destructive Pb-210-dating
Geografisk Tidsskrift, Danish Journal of Geography 98:1–9. A non-destructive gamma-spectrometric method was used to assay the sedimentation in the central Baltic Sea. Three cores from the Gotland Deep with water depths exceeding 230 m showed relatively high Pb-210 and Cs-137 but relatively little variation between cores in the curves for unsupported Pb-210. A constant rate of supply (CRS) modelling of the data revealed that there is a tendency of…
