Squids of the tropical Atlantic, poster with photos by Uwe Piatkowski, GEOMAR (german)
Squids are among the most striking creatures of the deep sea. This selection takes a look at their impressive diversity and thus illustrates the importance of the tropical ocean as a hotspot of biodiversity. The animals shown here were caught during the METEOR expedition M97 in June 2013 in the central East Atlantic south of Cape Verde. For this purpose, plankton nets were deployed at night or at dusk down to a depth of 4,000 metres. Most of the specimens are still in the larval or juvenile stage and live down to a depth of about 1,000 metres. These typical deep-sea creatures can grow to several metres in length when fully grown.

Deep Sea fishes, poster with photos by Solvin Zankl (german)
With glowing hinges on their heads, mouths larger than their bodies and dangerous-looking fangs, many of these creatures seem to have stepped straight out of a science fiction film. In fact, these fish live in the deep sea, the largest habitat on our planet. For us humans, it is just as inaccessible, hostile and alien as outer space. The photos shown here are exhibits from the collection of Dr Johannes Kinzer. The marine biologist and former aquarium director of the Kiel Institute of Oceanography (IfM) collected these deep-sea fishes during numerous expeditions in the 1960s and 1970s in the Atlantic, Pacific and Indian Oceans.

Background Information on Marine Research (external links)


World Ocean Review
Numerous researchers and partners have contributed to the publications, representing years of commitment to the oceans and the highest scientific standards. The aim of the "World Ocean Reviews" is to present scientifically sound findings in a comprehensible form and thus to serve all those who wish to participate actively and in an informed manner in current discussions in the field of marine research.


Future of the Gulf Stream circulation
There has been lots of speculation about the Gulf Stream. But what kind of scientific evidence exists? Nine experts summarize this evidence in this brochure. One of the key messages: The Gulf Stream circulation will not collapse in the near future. But this is not a reason to be complacent. A Brochure from the Deutsches Klima-Konsortium and the German Marine Research Consortium.
