POSEIDON POS457

R/V POSEIDON cruise POS457 is part of a cooperative project between FB1 (workings group of Prof. Dirk Nürnberg and Prof. Martin Frank) and FB4 (working group of Prof. Kaj Hoernle). The cruise will focus on sampling of high-resolution sediment cores at the southern and eastern sectors on the Icelandic shelf to (1) further develop a detailed marine tephrachronology of Iceland in order to improve our knowledge of the spatio-temporal evolution of Icelandic volcanism and related hazards to human population and economy, and (2) to investigate the Holocene interrelationships between oceanic, terrestrial and atmospheric processes.

A grab is getting prepared on the working-deck of RV POSEIDON. The instrument is used to take sediment-samples from the sea floor. Photo: C. Bonanati, GEOMAR




A gravity corer lies in its stage, ready prepared for the next operation on RV POSEIDON. The gravity corer is the most important instrument on cruise POS457. It is used to take sediment cores up to a length of 10 m. The cores enable scientists to reconstruct the past development of climate and volcanism in Iceland. Photo: N. Schattel, GEOMAR
