Mapping the seafloor/Die Kartierung des Meeresbodens

Fig. 1: Here you can see the 3D representation of the seafloor. Abb. 1: Hier sehen sie den Meeresboden als 3D-Karte.

(Deutsche Version unten) How do you plan research that is to be conducted at the seafloor in 4000 meter water depth? How do you choose the locations for your studies in a large area that you may not know much about yet? How do you pick the best spot to deploy sensors? – Which path […]

Wer ist eigentlich Eddy?/Who actually is Eddy?

(English version below) Das war eine häufige Frage an Bord zu Beginn unserer Forschungsfahrt. Denn das „Eddy“ Teil unserer wissenschaftlichen Untersuchungen wird, ergab sich relativ kurzfristig. Eddies sind temporäre Wasserwirbel mit einem Durchmesser von mehreren hundert Kilometern, die lange Strecken durch den offenen Ozean zurücklegen können, bevor sie sich irgendwann auflösen. Sie können von der […]

– 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 […]
