Scheme of the tropical Pacific: Strong growth of plankton (1) leads to a high oxygen consumption and extended oxygen minimum zones (2). Ocean currents (3) at a few hundred meters depth provide an influx of oxygenated water from the subtropics (4). Fluctuations of the trade winds (5) influence the strength of these currents.

Trade Winds ventilate the Tropical Oceans

19 December 2014/Kiel. Long-term observations indicate that the oxygen minimum zones in the tropical oceans have expanded in recent decades. The reason is still unknown. Now scientists at the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Collaborative Research Centre 754 "Climate – Biogeoc...


New challenges for ocean acidification research

December 18, 2014 / Kiel, Villefranche-sur-mer. To continue its striking development, ocean acidification research needs to bridge between its diverging branches towards an integrated assessment. This is the conclusion drawn by Prof. Ulf Riebesell from GEOMAR Helmholtz Centre for Ocean Research Kiel...

Oceanographic data from Antarctica show that warmer water spills onto the West Antarctic continental shelf, where they warm the shelf. Graphic: S. Schmidtko, ed. C. Kersten, GEOMAR

Antarctica: Heat comes from the Deep

04 December 2014/Kiel. The water temperatures on the West Antarctic shelf are rising. The reason for this is predominantly warm water from greater depths, which as a result of global change now increasingly reaches the shallow shelf. There it has the potential to accelerate the glacier melt from bel...

Baltic Sea: Climate Change counteracts decline in eutrophication

01 December 2014/Kiel. Despite extensive measures to protect the Baltic Sea from anthropogenic activities since the late 1980s, oxygen concentrations continue to decrease. Rising temperatures in the bottom water layers could be the reason for the oxygen decline. This paper reports on the first compr...
