An evaluation of the determination of heavy metals, barium and phosphorus in sea-bed sediments
(NGU Bulletin (430), Journal article, 1996)An evaluation of the results obtained by following established procedures for collection and analysis of sea-bed sediments indicates that there is an acceptable reproducibility using nitric acid extraction and subsequent ... -
Benthic foraminiferal evidence of environmental change in the Skagerrak over the past six decades
(NGU Bulletin (430), Journal article, 1996)High resolution analyses of fossil benthic forminiferal assemblages have been performed on two short (<40cm) sediment cores from the deep Skagerrak Basin, NE North Sea. 210 Pb-datings of replicate cores from the same two ... -
Late Quaternary geological development of the Jutland Bank and the initiation of the Jutland Current, NE North Sea
(NGU Bulletin (430), Journal article, 1996)Using shallow seismic and core data, a reconstruction has been made of the Late Pleistocene-Early Holocene palaeogeography of Jutland Bank, NE North Sea. A division of Late Pleistocene and Holocene deposits into five ... -
Organic matter mineralization and the effects of petroleum pollution in a shallow-marine sediment - a case study from Århus Bugt, Denmark
(NGU Bulletin (430), Journal article, 1996)Organic geochemical analyses of core samples from the Station 6 site in Århus Bugt, Denmark, show systematic changes with depth below the sediment-water interface. Over the upper 6-7 centimetres, corresponding to the ... -
Recent sediment accumulation in the Norwegian Channel, North Sea
(NGU Bulletin (430), Journal article, 1996)In the Norwegian Channel 35 box cores were taken for sedimentological analysis, and 210Po a- and137Cs y-spectroscopy to determine sedimentation rates. Grain sizes were determined and X-ray photographs of the cores were ... -
Recent sedimentation rates across the Norwegian Trough
(NGU Bulletin (430), Journal article, 1996)From the systematic sampling of 20 stations of the Norwegian part of the Skagerrak in 1993, six cores were chosen for determination of recent sedimentation rates by the lead-210 method and verifications by Cs-137 depth ... -
Regional distribution of manganese, phosphorus, heavy metals, barium and carbon in sea-bed sediments (0-2 cm) from the northern part of the Norwegian Skagerrak
(NGU Bulletin (430), Journal article, 1996)The regional distribution of manganese, phosphorus, heavy metals, barium and organic carbon in sea-bed sediments (0-2cm) from the northern part of the Norwegian Skagerrak has been mapped and the results discussed in the ... -
Sea-bed sediments and sediment accumulation rates in the Norwegian part of the Skagerrak
(NGU Bulletin (430), Journal article, 1996)Grain-size analysis show that the sea-bed sediments over large areas in the Norwegian Trench and along its northern slope consist of homogeneous silty clay with a clay content of 50-75% and generally less than 2% sand. ... -
Suspension sedimentation of coarse silt and sand in northern Skagerrak: textural and mineralogical trends
(NGU Bulletin (430), Journal article, 1996)The minor coarse-silt and sand fraction of muddy bottom sediments at 74 sites in northern Skagerrak is interpreted to have been mostly transported in suspension, aided by frequent reworking and the buoyancy of large ...
