High-resolution climate reconstruction for the holocene based on growth chronologies of the bivalve Arctica Islandica from the North Sea
(Univ. Bremen, 2004)
High-resolution climate reconstruction, North Sea, annual banded proxy, Arctica islandica. - Until now, there has been no published documentation of North Sea year-to-year climate variability during the last 8000 to 10000 ...

Dinoflagellate cysts, paleoceanography, paleoenvironment, Late Quaternary, Norwegian-Greenland Sea. - Dinoflagellate cysts have been investigated in nine short sediment cores as well as two long sediment cores from the ...
The role of mesozooplankton grazing in the biogeochemical cycle of silicon in the Southern Ocean
(Univ. Bremen, 2004)
Calanus simillimus, Rhincalanus gigas, grazing, biogeochemistry, biogenic silica. - The role of copepod grazing, particularly of Calanus simillimus and Rhincalanus gigas, in the biogeochemical cycles of silicon (Si) and ...
Quantitative estimation of aerobic diagenetic overprint of palaeoproductivity signals
(Univ. Bremen, 2008)
Organic-walled dinoflagellate cysts, oxidation, degradation, organic matter. - Species-selective aerobic decomposition affects fossil organic-walled dinoflagellate cyst (dinocyst) records and hence dinocyst-based interpretations ...
Chironomiden als Anzeiger für die holozäne Klima- und Umweltgeschichte von Store Koldewey in Nordostgrönland
(Univ. Köln, 2009)
Sedimentkerne aus zwei hocharktischen Seen (Duck und Hjort Lake) auf Store Koldewey, einer Insel auf Nordostgrönland, wurden auf ihre fossilen Chironomiden-Vergesellschaftungen untersucht. Im gesamten Holozän konnten 18 ...
Seasonal dynamics and characterization of coccolithophore export production in two major upwelling regions
(Univ. Bremen, 2008)
Coccolithophores, a major group of the nanophytoplankton, belong to the class Prymnesiophyceae.The cells of coccolithophores are typically surrounded by layer(s) of calcium carbonate plates, the coccoliths. Certain ...
Palaeodiversity, palaeobiology and palaeoecology of middle devonian crinoids from the Eifel type region
(Univ. Köln, 2009)
This doctoral thesis deals with crinoids from the Middle Devonian (U. Eifelian to L. Givetian) of the Eifel Synclines (western Rhenish Massif, Germany) and secondary with U. Eifelian to U. Givetian crinoids of the eastern ...
