    Geochemistry of sediments from the mid-oceanic Kolbeinsey Ridge (1994)
    PANGAEA
    In:  Supplement to: Lackschewitz, Klas Sven; Wallrabe-Adams, Hans-Joachim; Garbe-Schönberg, Dieter (1994): Geochemistry of surface sediments from the mid-oceanic Kolbeinsey Ridge, north of Iceland. Marine Geology, 121(1-2), 105-119, https://doi.org/10.1016/0025-3227(94)90160-0

    Publication Date: 2024-06-28
    Description: In order to assess recent submarine volcanic contributions to the sediments from the active Kolbeinsey Ridge, surface samples were analyzed chemically. The contribution of major and trace elements studied differ within the study area. A statistical analysis of the geochemical variables using factor analysis and cluster method allows to distinguish possible sample groups. Cluster method identifies three distinct sediment groups located in different areas of sedimentation. Group 1 is characterized by highest contents of Fe2O3, V, Co, Ni, Cu and Zn demonstrating the input of volcaniclastic material. Group 2 comprises high values of CaCO3, CaO and Sr representing biogenic carbonate. Group 3 is characterized by the elements K, Rb, Cs, La and Pb indicating the terrigenous component. The absolute percentage of the volcanic, biogenic and terrigenous components in the bulk sediments was calculated by using a normative sediment method. The highest volcanic component (〉 60% on a carbonate free basis) is found on the ridge crest. The biogenic component is highest (10-30%) in the eastern part of the Spar Fracture Zone influenced by the East Iceland Current. Samples from the western and southeastern region of the study area contain more than 90% of terrigenous component which appears to be mainly controlled by input of ice-rafted debris.

    Radionuclides in the Weddell Sea (1994)
    PANGAEA
    In:  Supplement to: Rutgers van der Loeff, Michiel M (1994): 228Ra and 228Th in the Weddell Sea. In: Johannessen, O M; Muench, R D & Overland, J E (eds.), The polar oceans and their role in shaping the global environment. Geophysical Monograph Series, American Geophysical Union, 540 pages, ISBN 0-87590-042-9, 85, 177-186
    Details
    Publication Date: 2024-06-26
    Description: 228Ra and its granddaughter 228Th were measured on a N-S transect from 45's to the Antarctic continent across the Antarctic Circumpolar Current (ACC) and the Weddell Sea. The distributions of 230Th, 228Th and 228Ra show that southward transport across the ACC of Circumpolar Deep Water (CDW), the source of Warm Deep Water (WDW) in the Weddell Sea, occurs on a time scale between 8 and 30 years, in qualitative agreement with estimates of the upwelling rate of WDW. The distribution of 228Ra in deep waters is controlled by advection and isopycnal mixing rather than diapycnal mixing. In the Weddell Sea, deep-water 228Ra activities reach 15-20 dpm/m**3. Enrichment in deep water is controlled by the production in the deep-sea floor, favoured by low biogenic sediment accumulation rates and consequently high 232Th contents in the surface sediment (3 to 5 dpm/g). The highest 228Ra value (73 dpm/m**3) was observed near the sea floor in a channel where an eastern outflow of Weddell Sea Bottom Water (WSBW) is suspected. It is not yet known whether this value is produced in-situ by accumulation in the stratified bottom water, or contains a Signal of enrichment in shelf- and Ice Shelf Water. High 228Ra activities on the south-eastem shelf (22 dpm/m**3) and low activities offshore yield an estimated residente time of 1.5 years on this shelf and imply slow exchange with offshore waters.

    Stable isotope ratios on planktonic foraminifer N. pachyderma of surface sediments from the Arctic Ocean (Table 1) (1994)
    PANGAEA
    In:  Supplement to: Spielhagen, Robert F; Erlenkeuser, Helmut (1994): Stable oxygen and carbon isotopes in planktic foraminifers from Arctic Ocean surface sediments: Reflection of the low salinity surfac water layer. Marine Geology, 119(3-4), 227-250, https://doi.org/10.1016/0025-3227(94)90183-X

    Description: Planktic foraminifers Neogloboquadrina pachyderma (sin.) from 87 eastern and central Arctic Ocean surface sediment samples were analyzed for stable oxygen and carbon isotope composition. Additional results from 52 stations were taken from the literature. The lateral distribution of delta18O (18O/16O) values in the Arctic Ocean reveals a pattern of roughly parallel, W-E stretching zones in the Eurasian Basin, each ~0.5 per mil wide on the delta18O scale. The low horizontal and vertical temperature variability in the Arctic halocline waters (0-100 m) suggests only little influence of temperature on the oxygen isotope distribution of N. pachyderma (sin.). The zone of maximum delta18O values of up to 3.8 per mil is situated in the southern Nansen Basin and relates to the tongue of saline (〉 33%.) Atlantic waters entering the Arctic Ocean through the Fram Strait. delta18O values decrease both to the Barents Shelf and to the North Pole, in accordance with the decreasing salinities of the halocline waters. In the Nansen Basin, a strong N-S delta18O gradient is in contrast with a relatively low salinity change and suggests contributions from different freshwater sources, i.e. salinity reduction from sea ice meltwater in the south and from light isotope waters (meteoric precipitation and river-runoff) in the northern part of the basin. North of the Gakkel Ridge, delta18O and salinity gradients are in good accordance and suggest less influence of sea ice melting processes. The delta13C (13C/12C) values of N. pachyderma (sin.) from Arctic Ocean surface sediment samples are generally high (0.75-0.95 per mil). Lower values in the southern Eurasian Basin appear to be related to the intrusion of Atlantic waters. The high delta13C values are evidence for well ventilated surface waters. Because the perennial Arctic sea ice cover largely prevents atmosphere-ocean gas exchange, ventilation on the seasonally open shelves must be of major importance. Lack of delta13C gradients along the main routes of the ice drift from the Siberian shelves to the Fram Strait suggests that primary production (i.e. CO2 consumption) does probably not change the CO2 budget of the Arctic Ocean significantly.
