  2. Sedimentverteilung im Seegebiet bei Bokniseck, Eckernförder Bucht, westliche Ostsee (sediment distribution at Bokniseck, western Baltic Sea; map)

    Wefer, Gerold; Tauchgruppe, Kiel
    A detailed topographic survey was carried out in the "Hausgarten"-area of the Joint Research Programm 95 of the University of Kiel by the Deutsches Hydrographisches Institut. Based on this information a sediment distribution map was constructed. A horizontal section extending from 0 to 27 m of water depth was investigated showing the distribution of pebbles and boulders, of algal growth, and exposed areas of glacial marl; the grain size distribution was determined for the various sediment types.

  3. Heavy metals and carbon isotope concentrations in recent Baltic Sea sediments

    Erlenkeuser, Helmut; Suess, Erwin; Willkomm, Horst
    Recent sediment cores of the western Baltic Sea were analyzed for heavy metal and carbon isotope contents. The sedimentation rate was determined from radiocarbon dates to be 1.4 mm/yr. The 'recent age' of the sediment was about 850 yr. Within the upper 20 cm of sediment, certain heavy metals became increasingly enriched towards the surface; Cd, Pb, Zn and Cu increased 7-, 4-, 3- and 2-fold, respectively, whereas Fe, Mn, Ni and Co remained unchanged. Simultaneously, the radiocarbon content decreased by about 14 per cent. The enrichment in heavy metals as well as the decrease in the 14C-concentration during the...

  4. Physical oceanography from the Drake Passage and Bransfield Strait during Meteor cruise M56

    Haardt, H; Maaßen, R
    This data publication is the electronic version of hydrographical and fluorometric data which were taken during the Antarctic cruise ANT I No. 56 of 'Meteor' from November 13th to December 18th 1980. The data were measured by means of the Optik Sonde (OS) of the SFB95. The data set contains the temperature and salinity profiles, the profiles of attenuation (extinction) coefficient at 670 nm wavelength and the fluorescence of chlorophyll expressed as chlorophyll a concentration values.

  5. Stable isotope ratios in shells of marine organisms

    Wefer, Gerold
    Oxygen and carbon isotope analyses have been carried out on calcareous skeletons of important recent groups of organisms. Annual temperature ranges and distinct developmental stages can be reconstructed from single shells with the aid of the micro-sampling technique made possible by modern mass-spectrometers. This is in contrast to the results of earlier studies which used bulk sampIes. The skeletons analysed are from Bermuda, the Philippines, the Persian Gulf and the continental margin off Peru. In these environments, seasonal salinity ranges and thus annual variations in the isotopic composition of the water are small. In addition, environmental parameters are weIl documented...

  6. Lebensraum und Fortpflanzung der Großforaminifere Cyclorbiculina compressa (Film)

    Wefer, Gerold; Sigl, Walter; Lutze, Gerhard F; Spindler, Michael

  7. Fragmentation and dissolution of benthic foraminifera in Kiel Bight, Baltic Sea, Germany

    Grobe, Hannes; Fütterer, Dieter K
    Early diagenetic ultrastructural alterations of benthic foraminifers of the genera Elphidium and Ophthalmina from the shallow water sediments of the Kiel Bight were investigated by scanning electron microscopy. Pure solution patterns were deduced from supplementary experiments.//Several carbonate destroying processes can be specified by ultrastructural patterns of the shell surfaces. Based on these patterns three zones are established, each showing different mechanisms of shell fragmentation: 1) zone of abrasion, 2) zone of disintegration, 3) zone of corrosion. This zonation depends on the water depth and is caused primarily by water agitation and by under saturation of the bottom water with respect...
