MARUM – The ocean in depth!

Prof. Dr. Jan-Hendrik Hehemann investigates the relevance of algae polysaccharides in marine cycles. His Marine Glycobiology working group is a joint group at both MARUM and MPI Bremen. Based on the group’s research, a new Glycobiochemistry group is being established within Faculty 2: Biology / Chemistry at the University of Bremen.

The sample material from the deep biosphere that was analyzed for the study came, among others, from the IODP Expedition 329 with the research drilling ship JOIDES RESOLUTION. Here, the ship is moored in the harbor of Papeete, Tahiti, before the start of the expedition. Copyright: John Beck, Integrated Ocean Drilling Program, U.S. Implementing Organization (IODP USIO).

‘Missing Ice Problem’ finally solved

To date computer models have been unable to reconcile sea-level height with the thickness of the glaciers - until now.

Silvia Vidal-Melgosa at the set up used for the sampling of particulate organic matter by sequential filtration of 100 litre of seawater at Helgoland. The picture shows the collection of one filter where organic matter (in this case matter with molecular sizes between 10 and 3 micrometre) has been retained.

Sweet marine particles resist hungry bacteria

A sugar in algae resists rapid microbial degradation. With this finding researchers show that this sugar can potentially act as an important carbon sink.

Expedition SO273 "Marion Rise"

The video material shown here was recorded with the ROV MARUM-QUEST in the Indian Ocean during the expedition SO273 “Marion Rise”.

The Project "Marion Rise" is an international cooperation between Germany, USA, and China. The expedition was funded by the Federal Ministry of Education and Research (Germany) and the National Science Foundation (USA).

The cruise SO273 was abandoned after 10 days station work due to the COVID-19 pandemic.
