The SO289 research cruise aboard R/V Sonne, which involves the trans-Pacific leg of the GEOTRACES program, is a 48-day expedition consisting of 48 planned CTD cast stations taken at approximately 1-3° intervals all the way from the coast of Chile to the South Fiji Basin (Figure 1). The chief objective of this research cruise is […]
[deutsche Version unten] 5th Weekly Report SO289 Progress: We have had a successful last few days, following our unplanned detour to Tahiti. We commenced sampling again on Wednesday morning (March 23) just outside the EEZ of French Polynesia and have been able to conduct daily station occupations with CTD casts and in situ pump deployments. […]
Weekly Report / Wochenbericht SO289 (Deutsche Version unten) Progress: We have had a successful week, with daily station occupations with smooth CTD casts and in-situ pump deployments. We have made steady progress west towards Noumea along our 31.5°S latitude cruise track. We have speeded up progress by combining our CTD casst with in situ pump […]
(Deutsche Version unten) It all started in the hallway of the ICBM in Oldenburg. I studied environmental sciences in my bachelors and spent large amounts of my time in the building of the ICBM (Institute for Marine Chemistry and Biology). And there, in the hallway, I saw it. A small replica of the RV SONNE. […]

We are now in international waters and will keep sailing west towards New Zealand and New Caledonia. We […]
(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) 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 […]
