Marine mineral resources, such as polymetallic nodules, crusts and submarine-exhalative sulphides have recently become the target of policy makers, mining companies and deep sea researchers. The lack … More info
by Dr. Julia Otte, AWI and Jessica Volz, AWI (deutsch s. u.) What gravity cores can tell us about the biogeochemistry of the Deep The deep sea has fascinated mankind since the early odysseys across the oceans – many myths have been told about the depths of the sea with the dreaded Kraken and Moby […]
(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 […]
(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 […]
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 […]
Working areas and sampling sites during cruise SO268 of RV SONNE by Timm Schoening (GEOMAR) and Peter Urban (GEOMAR) RV SONNE cruise SO268-2 followed in the footsteps of the first leg of this expedition – SO268-1. We continue to sample the diverse seafloor in two main working areas within the Clarion-Clipperton-Zone (North-East Pacific). Our scope […]
– 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 […]
(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 […]
