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

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.

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

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 to carbonate.

Observations of plankton production in Kiel Bay 1957 to 1975

This data volume presents a series of planktological observations carried out over a 19-year-period in Kiel Bight in the Western Baltic Sea. Three fixed stations were visited at monthly intervals, and the planktion standing stock was investigated in relation to depth and environmental factors, employing a standard observation programme. This consisted in the measurements of temperature, salinity, density, oxygen, phosphorus, seston, protein and chlorophyll a. Additional measurements comprised in the caloric content of seston, particulate organic carbon and nitrogen, as well as dry weight and organic matter of plankton, sampled by vertical hauls of three plankton nets of different mesh size.
