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 […]

BOBO and the 7 (+7) dwarfs: How to sense the deep sea

Sensor platform with a optical backscatter sensor an an ADCP.

by Sabine Haalboom (NIOZ) The first half of the cruise has passed and we’ve finished the baseline studies in the Belgian license area. Doing my PhD research in marine geology at the Royal Netherlands Institute for Sea Research (NIOZ), my main interest is the particle dynamics in the bottom boundary layer (i.e. the layer close […]

(English below) Manganknollen – Entstehung und wirtschaftliche Relevanz von Jessica Volz, Sophie Paul und Julia M. Otte Während der ersten globalen Forschungsexpedition der HMS Challenger in den 1870er Jahren wurde das große Ressourcenpotential der Tiefsee deutlich. An Bord der HMS Challenger wurden zahlreiche unbekannte marine Organismen sowie mineralische Konkretionen vom pazifischen und atlantischen Meeresboden, die […]

At the bottom of the Ocean, in ~4000m water depth they can be found in high abundances: Manganese nodules. Industry and states are interested in these potato-sized objects as a new metal resource. But before commercial mining will start, the potential ecological impacts need to be investigated. Therefore, the project MiningImpact (funded through JPI Oceans) […]
