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 […]
Als ich heute morgen aufwache und aus dem Fenster sehe, erkenne ich Land am Horizont. Wir sind auf dem Weg nach Dänemark, genauer gesagt nach Hirtshals. Dort werden zwei Ingenieure von Kongsberg von Bord gehen, die ein neu entwickeltes Echolot/ADCP installiert haben. Bevor sie von Bord gehen, machen wir noch ein Gruppenfoto (siehe oben) Alle […]
Living and working on board the RV Alkor provides many opportunities to collect valuable data that helps us to understand what is happening in the Baltic Sea. Working as efficiently as possible during the limited time we have at sea means that we also have to work at night time – when all others are […]
– 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 […]
Als mein Wecker heute morgen klingelt, springe ich aufgeregt aus dem Bett, heute beginnt die 3 wöchige Forschungsfahrt auf der Nordee mit der Poseidon. Es ist meine erste Seefahrt und ich freue mich, die Wissenschaftler auf ihrer Expedition begleiten zu dürfen. Ich selber bin Studentin und studiere Physik des Erdsystems an der Christian-Albrechts-Universität in Kiel. […]
(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 […]
After the fair amount of work on the board and sampling the exciting marine organisms, Alkor brought us safely to Kalmar in Sweden, where two of our scientific crew left and two new participants joined us. For me, as a first-time-on-board-attendee, the arrival at the harbor was a great experience. All our scientific crew went […]
One important goal of our long-term data series and of the present cruise is to increase the understanding of the feeding ecology, reproduction and population structure of key Baltic fish species. Why is Baltic cod getting thinner? How are herring and sprat competing for zooplankton? How are the two genotypes of cod in the Baltic, […]
Time flies out at sea. Benefiting from perfect, calm and sunny weather, we have now already completed hydrographic measurements and fish and plankton sampling in Kiel Bight, Mecklenburg Bight, Arkona Basin, Gdansk Deep and Gotland Basin. For a first summary of work completed till now, check out our first weekly report, now online (in German), […]
