Bachelor/Master thesis: last glacial high productivity events in the Arctic


Background During the last glacial maximum, the Arctic Ocean was characterized by extreme and regionally very different environmental conditions. While land masses and a large part of the ocean were covered by ice masses more than 1 km thick, there is evidence of local marine high production events. Combined planktonic and benthic foraminifera analyses allow us to distinguish pure primary production from primary plus export production events. Studies of “Atlantic species” show us the importance of Atlantic water advection during these events. You will work at the Alfred Wegener Institute in Bremerhaven, supervised by Jutta Wollenburg, Jens Matthiessen and Christoph Vogt (University of Bremen).

Tasks By application of foraminiferal fauna, oxygen/carbon isotope analyses, Mg/Ca- ratios and radiocarbon dating on sediment cores from the Arctic Ocean, you will identify and verify such high-productivity events off Spitsbergen in the time span from 28 to 12 kyrs. Internships on this topic are also possible.

Requirements Micropaleontological knowledge is welcome, joy and interest in such investigations are a prerequisite.

Further Information Please contact Jutta Wollenburg ([email protected]; +49(471) 4831-1851) for further information.

The place of employment will be Bremerhaven, 27570.

Start: as soon as possible
