Viruses as Modulators of Interactions in Marine Ecosystems

GEOMAR scientists show a new picture of the role of viruses in the ocean

Complex Movement of Plates decoded

New Zealand-German study delivers new insights into the works of southwest Pacific submarine volcanism

In the Miocene the land bridge near modern Panama was not yet closed. Relatively fresh water from the Pacific reached the Caribbean. This has been shown, for example, by studies in the Central Caribbean (ODP1000).  Sediment samples taken from ODP1006 now show, however, that between 11.5 and 9.5 million years before today this relatively low-salt water did not leave the Caribbean and thus could not influence the North Atlantic circulation.
