The Kosmos 2014 GC Blog

 

From January to April 2014, 70 BIOACID and SOPRAN scientists investigate at Gran Canaria how the plankton community of open ocean waters reacts to ocean acidification.

The KOSMOS mesocosms are brought to the island by the German research vessel POSEIDON and deployed just off the harbour of Taliarte. After adding carbon dioxide to the "giant test tubes" to simulate future conditions, samples and measurements will be taken every second day. Some of the samples are analysed in the labs of PLOCAN (Plataforma Oceánica de Canarias), others are taken to the home insititutions.

Fish larvae will be released into the mesocosms after some weeks to learn more about the future development of economically important species. With a large plastic bag, the scientists will capture deep-sea water to simulate an upwelling event inside the bags. They also collect Saharan dust at Cape Verde and add exact quantities to the mesocosms to observe reactions to this natural extra-feeding.

Last sampling, last box, last day …..
  Last sampling … It’s an old tradition in German oceanographic research that the last sampler brings up a very special sample. Well, in the case of KOSMOS-GC2 it was Tequilla Sunrise. Actually, it was rum instead of tequilla and the sunrise was kind of upside down. But Paul prepared an [...]

Untold stories | Geschichten, die noch nicht erzählt wurden
[deutsche Version unten] The different names of the Atlantic The most beautiful thing about the village “Taliarte” is the amazing view on the Atlantic – and the Atlantic is the reason why we are here. We want to learn, explore and understand it. And we would like to stimulate people to treat [...]

The visitors | Die Besucher
[deutsche Version unten] I am the lucky person within the mesocosm team, with the job to coordinate the interplay between different groups. Logistics and coordination within a mesocosm study require a long preparation time. You have to travel to the experimental site long before the experiment [...]

Primary Production and the pleasure of sampling
Phytoplankton play a key role in the global carbon cycle. These organisms take CO2 of the environment and release O2, by a process called oxygenic photosynthesis, that affects the gas composition in the ocean, and therefore in the atmosphere. Primary production is essential to understand and [...]

Sediment trap samples don´t smell like apple-pies
     Some weeks ago Ulf, Paul, Ted and I had an interesting meeting about an unplanned measurement which could complement the results that we were producing. It sounded great, and immediately we all began planning the organization, the sampling, the treatments, and how to coordinate the [...]
