The largest and probably most expensive scientific equipment on board of RV SONNE on the present leg is a remotely operated deep-diving “robot” called ROV KIEL 6000. “ROV” is the abbreviation for “Remotely Operated Vehicle”. The ROV provides “eyes and arms in the deep sea”. ROV KIEL 6000, which got its name from the city […]

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 […]
