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 predict the biogenic flux of CO2 into the oceans. […]

“Summer holiday” vs. KOSMOS routine

*German version below*   Delicious tropical fruits for breakfast, lonesome strolls on the picturesque cliffside towards the PLOCAN lighthouse at dawn, watching a nice sunrise and cutting through the waves on adventurous motorboat rides and – with a bit of luck – spotting some turtles, flying fish or even a hammerhead shark in the crystal-clear […]

Eier, wir brauchen Eier! – Germans are always lucky!

  -english version see below- Eier, wir brauchen Eier. Diese Worte stammen von einem großen deutschen Philosophen des 20. und 21. Jahrhunderts und beschreibt ziemlich genau unsere letzten Wochen. Nachdem das Tiefenwasser zugegeben wurde, hatte das Phytoplankton Zeit genug sich zu vermehren und dem Zooplankton sollte dieser reich gedeckte Tisch auch Anlass genug sein Nachkommen zu […]

Turning an ocean desert into plankton paradise

It may seem like the perfect sea to swimmers, snorklers, and divers – crystal clear, turquoise water with an underwater visibility of 30 metres and more. Among marine scientists this is often referred to as an ocean desert. The concentrations of plant nutrients in these waters are so low, that it takes special instruments and […]

“Who is KOSMOS” Pt. 1 | “Wer ist KOSMOS” Pt. 1

[deutsche Version unten] The experiment is already running for four weeks now and we still haven’t introduced all members of the project. Starting with the series “Who is KOSMOS” we take the chance to present each of the groups taking part in the study. As an alphabetic order seems rather boring, we will follow an […]

A normal sampling day | Ein normaler Probennahmetag

[deutsche Version unten] A normal sampling day starts at 7:30am just before the sun rises over Gran Canaria. The sampling team packs all equipment needed into the KOSMOS bus to transport it to the harbour just around the corner. The equipment comprises integrated water samplers for gas samples, pumps to sample non gas samples, a […]

Autumn cleaning

Some days ago we started with the most fun part: cleaning the mesocosm bags from outside with a window scraper and a brush operated by a diver. It may sound strange since our experiment is inside the bags, but we don’t want to have algae growing on the outside and shading the inner environment. It […]
