The Onshore Baltic Sea Science Party Has Gathered In Bremen

From September 13 – November 1 last year the Center for Geomicrobiology participated in the IODP Baltic Sea Paleo Expedition 347 where scientists collected more than 1600 meters of sediment core material and thousands of pore water samples.

Bremen in Germany is one of the three places in the world where researchers store mud cores from their expeditions. Here there are 220,000 tubes with approximately 151 kilometres of seabed mud cores from 86 different expeditions. Cores from the Baltic Sea expedition will also end up here so that research groups all over the world can get access to them. Photo: Copyright: MARUM, University of Bremen.

From September 13 – November 1 last year the Center for Geomicrobiology participated in the IODP Baltic Sea Paleo Expedition 347 where scientists collected more than 1600 meters of sediment core material and thousands of pore water samples.

The Center for Geomicrobiology had no less than three scientists on board the expedition: Professor Bo Barker Jørgensen who is Co-Chief Scientist on BSP, Research Assistant Ian Marshall and PhD student Andrea Torti.

On the 22 of February Bo, Ian and Andrea went to Bremen Core Repository at Center for Marine Environmental Sciences (the Marum) to participate in the onshore science party for detailed sampling and analysis of the collected sediment and porewater cores.

Opening the cores will allow them to finally see in detail what kind of material the expedition has collected. One of the party’s main interests is finding evidence for changes in environmental conditions. For example, we know that the Baltic Sea used to be a lake and became connected to the oceans after the last ice age thousands of years ago. With the cores the party can now study the differences in the lake and marine sediments in great detail. We hope amazing discoveries will follow.
