14.07-20.07.2014 (Port Louis \/ Mauritius)
\n<\/strong>Here is the second and last weekly report from our SPACES (“Science\u00a0Partnerships for the Assessment of Complex Earth System Processes”) SONNE\u00a0SO234-2 cruise, a training and exchange trip between students of southern\u00a0Africa and Germany, funded by the BMBF as part of the OASIS (“Organic very\u00a0short-lived substances and their air-water exchange from the Indian Ocean to\u00a0the stratosphere “and SO234-2 SPACES, 03G0235A) project. The daily blog\u00a0(live from on board) can be followed under www.oceanblogs.org\/sonne-oasis<\/a>.\u00a0In the second week of our training campaign, we focused on practical work as a scientist on board a\u00a0research ship. On 16\/07\/2014 we reached approximately 29\u00b0 S and 58\u00b0 E, our “Drifter station”, which\u00a0was in a CO2 sink in the subtropical southern Indian gyre. We stayed in the same water mass for 48\u00a0hours to investigate the chemical and biological factors that influence the trace gas exchange\u00a0between the ocean and atmosphere. What does this mean in practice? RV SONNE drifted with the\u00a0drifter for two full days in a southwest arc and then in a northerly direction (see Figure 1). While\u00a0following the drifter, we increased the frequency of ocean profiles and atmospheric radiosonde\u00a0intervals (every 6 hours), since there is not so much data in the subtropical Indian gyre.<\/p>\n

It was the first time the students had to deal with working in shifts for 24\/2. They had to choose a\u00a0measurement to perform over the whole period and present it at the end of the cruise. What have\u00a0they measured? Among other things, 288 Niskin bottles were filled with 3456 L seawater to\u00a0investigate more than 40 parameters. Most parameters were analyzed directly on board by the\u00a0students and researchers, while a lesser portion of the samples were processed and stored for later\u00a0analysis in the home laboratory. The 40 parameters included measurements of halogenated and\u00a0sulfur-containing short-lived substances, CO2, nutrients, DNA and pigments for identifying phytoplankton communities. The data will help later to get a better understanding of biogeochemical processes in the tropical Indian Ocean. In addition, the first ozonesonde and 6 radiosondes were launched and numerous atmospheric chemistry measurements were performed. In the following days, the students had to evaluate their own data. In groups of two, they enthusiastically prepared the interpretation of their results. Two days later, they presented their work and wrote a mini-cruise report. It is a compliment to “our” students that they walked conscientiously and diligently to action and gave very successful lectures despite the strong swell. After 11 days, 20 hours, and 2379 nm our trip ended on 07\/20\/2014 in Port Louis \/ Mauritius (Figure 2a). With a joint dinner and a formal goodbye, we reluctantly let “our” students disembark. We want to thank the SO234-2 students and scientific team and the entire team of FS SONNE for a very successful training and science cruise, and especially for the great team spirit on board … “One for all, all for one” … (Figure 2b).<\/p>\n

Yours truly,<\/em>
