Behold the mighty conductivity temperature depth (CTD) rosette! This is one of the workhorses of ocean research. Sensors measure conductivity (a proxy for salinity), temperature, light level, and other environmental parameters as they change with depth. These sensors are attached to a circular frame called a rosette that holds an array of sampling bottles that […]
Tobias Strickmann, PhD student at GEOMAR, is a jack-of-all-trades here on the Sonne. He collects environmental DNA samples for Véronique Merten, a postdoc at GEOMAR, and he also works with Anita Butterley, PhD student at the University of Tasmania, to filter water for proteomics samples. In addition to being a great team player, he also […]
Carbon’s journey to the deep Just like their larger cousins, the terrestrial plants, phytoplankton convert atmospheric carbon dioxide (CO2) into organic carbon. If their tiny carbon-based bodies sink from the surface ocean to the deep sea and sediments, the CO2 is then removed from the atmosphere for hundreds to thousands of years. The remains of […]
For many people, radium brings to mind Marie Curie and her historic discoveries and the dangers they posed. But radium is found all around—in rocks, sediments, and water— in such small amounts it cannot harm us. Several isotopes of radium exist naturally in the environment. They decay at different rates, and scientists like Cátia Ehlert […]
Throwback to the FYORD summer school, organized by PostDocs for Master’s and PhD students At the beginning of this year, a group of postdocs from GEOMAR and Kiel University, with the great support of FYORD and PACT, came together to brainstorm ideas for a potential summer school tailored for Masters and PhD students in marine […]
This cruise is a long time coming—the original proposal submitted by Chief Scientist Prof. Dr. Eric Achterberg estimated it would happen in 2017 or 2018! After we finally loaded the ship with equipment and 40 motivated scientists in late October 2024, we had to wait a few more days in port for repairs and inspections. […]
von Hjördis Lorenzen (Team Gender Equality & Diversity) *** English Version Below *** Anmerkung: Begriffe in Kursivschrift werden am Ende des Artikels im Glossar erläutert. Die Vielfalt der Meere und ihrer Ökosysteme spiegelt sich nicht nur in der Forschung am GEOMAR wider, sondern auch in der Vielfalt der Menschen, die diese Arbeit vorantreiben. Doch in […]
Interview and Text: Anja Conventz In addition to the captain, nautical officers, deck and engine crew, electricians, electronic engineers, cooks and a ship’s doctor, the crew of the SONNE includes four stewards. One stewardess who is also on board during our cruise SO307 is Jessica Münch, who has been working on SONNE since November 2021. […]
Interview und Text: Anja Conventz Neben Kapitän, nautischen Offizieren, Decks- und Maschinenmannschaft, Elektrikern, elektronischen Ingenieuren, Köchen und einer Schiffsärztin gehören vier Stewards zur Crew der SONNE. Eine Stewardess, die auch während unserer Fahrt SO307 mit dabei ist, ist Jessica Münch, die seit November 2021 an Bord arbeitet. Um Euch einen Einblick in die Arbeit einer […]
Geschrieben von Clara Winguth, Masterstudentin am GEOMAR, Übersetzung von Josefine Karnartz, Doktorandin am GEOMAR Es dauerte nicht lange nach Verlassen des Hafens, da entdeckten wir schon in der Ferne die ersten Walblase! Sofort holten alle ihre längsten Kameraobjektive raus und fingen an zu knipsen. Doch da wussten wir noch nicht, dass das noch lange nicht […]
