News from ICBM
Recently, participants of the ICBM excursion to the mediterranean island of Giglio depicted their first impressions in a webblog. The students were accompanied by pleasant anticipation when starting their first snorkel tour, which was the first snorkeling experience to some of them at all. The initially even in wetsuits unexpected cold water did not derogate from scientific impetus.
The 147th RV METEOR expedition led scientists of ICBM, amongst team members of other research facilities, to the Amazon estuary. On whit sunday, 20 May, cruise M 147 will come to its end in Belém, Brazil. What made the estuary of the biggest stream on earth such attractive to the scientists? In his blog, local consultant Clive Maguire also lets us hear some vivid reports of the scientists aboard.
The Amazon is the largest river on Earth. About 20 per cent of the freshwater that flows from the continents into the world oceans comes from this gigantic tropical river. Together with the fluvial waters, large amounts of nutrients and plant debris are carried into the Atlantic. A recently discovered coral reef in the depths of the Atlantic and productive fish stocks directly depend on these inputs. Scientists and students from ICBM and the University UENF in Rio de Janeiro (Brazil) investigate on board of the German research vessel Meteor how organic debris from the Amazon influences marine ecosystems in the Atlantic.
It is known for quite some time that most bacteria of the open ocean "despise" dissolved organic matter. However, microorganisms from porous areas of the oceanic crust utilize a major part of these specific carbon compounds – most of them being excretory and decomposition products of marine algae and bacteria. The recent findings of an international study in which participated researchers of the ICBM-MPI Bridging Group Marine Geochemistry Prof. Dr. Thorsten Dittmar and Dr. Helena Osterholz, have been published in the recent issue of the scientific journal Nature Geoscience.
Scientists from Oldenburg, Brunswick and Chapel Hill (USA) have isolated a new bacterium from oil-contaminated marine water of the Deepwater Horizon oil spill in 2010.
In an interdisciplinary approach, researchers within the PhD training group EcoMol (The Ecology of Molecules) at the ICBM currently investigate the development of a so-called algal bloom under close-to-nature conditions in a laboratory.
The third ICBM Ph. D. day took place at the Wilhelmshaven site of the ICBM on 21 March. The doctoral candidates exchanged experiences and ideas and deepened contacts.
Eleven students are exploring Indonesian coral reefs up to 9 March, shark encounter included. Under scientific supervision of Prof. Peter Schupp, PhD student Mareen Möller (both ICBM) and Dr. Sebastian Ferse (Leibniz Centre for Tropical Marine research ZMT), the students are going to learn to sharpen their scientific focus on reef ecology during two weeks on Bunaken and Bangka island.
Since 2015, the Jacobs Career Fair is being held every year at the international Jacobs University Bremen. And for the third time already ICBM Junior Scientists Coordinator Dr. Ferdinand Esser was present as well. In the Campus Center of Jacobs University, marine science institutions, such as ICBM, AWI, ZMT and MPI, presented themselves, along with established enterprises as well as startups.
During the last glacial period, carbon dioxide has been "locked up" in the deep Southern Ocean. Current findings of scientists from Oldenburg and Bremerhaven, published in the recent issue of Science magazine, point at favourable conditions in the South Pacific. A team around geochemist Katharina Pahnke, who heads the Max Planck Research Group for Marine Isotope Geochemistry at the ICBM, presents evidence that during the last Ice Age the Southern Pacific must have been strongly stratified.
