(deutsche Version unten) But to what do I personally lose my sleep exactly? Sinking particles! More exactly, determining the flux of particles, thereby transporting carbon down into the deep of the ocean. Relying on available nutrients and sunlight, phytoplankton flourishes in the upper layers of the ocean by converting CO2 in organic molecules such as […]
(deutsche Version unten) With 33 scientists and 32 crew members on board, on the 22nd of February 2022 the Sonne expedition SO289 left Talcahuano, Chile, to conduct a South Pacific section as a part of the International GEOTRACES Program for assessing sources, sinks, distributions and internal cycling of trace elements and their isotopes in the […]
After 5 months of extremely intense preparations, the cruise SO287-CONNECT finished successfully in Guayaquil (Ecuador) on 11.01.2022, a harbour town in the tropical Pacific, the fourth ocean area we passed during a transit of around 6000 nm (11,000 km) towards this important working area of RV Sonne. After pandemic caused 20 months of work in […]
english version below Der letzte Tag an Bord. Die ersten von uns haben heute am 11.12.2021 bereits das Schiff in Richtung Heimat verlassen. Der Rest tritt morgen die Rückreise oder den verdienten Urlaub in Quito, der Hauptstadt Ecuadors oder auf den nicht weit entfernten Galapagos Inseln an. Zum Abschied einer Expedition wird traditionell ein Expeditionssticker […]
The cruise is coming to an end, and there are 8 days left until we enter the port of Guayaquil. While some of the measurements on board can be read out directly and preliminary interpretations are presented during the cruise, there are also a lot of samples that can only be analyzed in the laboratory […]
It was a nice and sunny day, like most of our days on the Alkor, the research vessel of our cruise. Steady noise coming from the winch and anticipating buzz, which surrounded a group of students with safety boots and helmets, filled the air. Once the upcoming net broke the water surface and got „gehievt“ […]
German version below The stars at night are the same, the world keeps turning and (almost) everything remains the same in the rest of the world. But after a 23-day transit between the Northwestern African coast and the Central American coast, with few signs of civilization (only a few cargo-ships at a distance) and a […]
(deutsche Version unten) Today, I have the opportunity to share on this blog my stay on board of the RV SONNE in which I embarked since the 10/12/2021, since one month after having left two days ago my beautiful and warm country, Senegal. Yes, I spent Christmas and New Year’s Eve at sea, an experience […]
Below 1.5° C rise above pre-industrial levels – this is the target global warming limit that scientists argue to hold to for the world to suffer less from the negative impacts of climate change. To achieve this goal, nations must commit not only to limit their carbon dioxide emissions but also other trace gas emissions […]
(deutsche Version unten) Greetings from the Pacific Ocean! We are Sigrid and Jesus, and together we have been working with the weather balloons on board. We launch radiosondes twice a day at stations. The radiosondes measures temperature, humidity, pressure, and position. Occasionally we launch ozone sondes, which is a completely different sonde attached to a […]
