by Sabine Gollner and Coral Diaz Recio Lorenzo (Royal Netherlands Institute for Sea Research NIOZ) The growth of the global economy and technological development is increasingly leading to scarcity of certain metals essential for the high-tech industry. Many countries including a number from the EU are currently exploring the potential of deep-sea mineral resource exploitation […]

The taste of sediment

by Henko de Stigter (Royal Netherlands Institute for Sea Research, NIOZ) Until somebody came up with the idea of mining polymetallic nodules from the abyssal depths of the Pacific Ocean, this place was one of the remotest and quietest on our planet. Far away from the brute natural forces of storms, floods, landslides, tsunamis and […]

by Dr. Sven Rossel, Katja Uhlenkott und Ann-Kathrin Weßel (deutsch s.u.) “Ah, you’re playing with mud again.” That is something biologists and geologists hear quite often on board. And yes, we are one of the parties “playing with mud”. But actually we, the biologists from Senckenberg, German Centre for Marine Biodiversity Research, are not interested […]

– The Ocean Floor Observation System (OFOS) and Remotely Operated Vehicle (ROV) – (deutscher Text siehe unten) Many samples that marine biologists gather during research cruises are taken “physically”, such as deep-sea mud that is heaved up from the seafloor onto the deck via different coring gears, and gets further processed in the labs. With […]
