Lab work at sea: a special experience

Everything has to be taped and lashed, also in the fume hood. Pipetting  on a moving ship is a challenge! On the picture:  Mara Heinrichs and Beatriz Noriega (Research Group for Marine Geochemistry).

We have been on board Sonne already for 15 days; it feels like we have been here since forever. We know where everything is and we are so used to our working space. But it was not always like this...

There’s also life without oxygen…

Kulturgefäße mit sauerstofffreiem Medium. Bislang unbekannte Bakterien, die ohne Sauerstoff leben können, sollen sich unter sauerstofffreien Bedingungen vermehren, damit wir sie später genau untersuchen können.
Culture vessels with oxygen-free media. So far unknown bacteria that can live without oxygen are supposed to grow under oxygen-free conditions for later studies.

The microorganisms in the ocean enjoy the sun and warmth of the equator, just as we scientists do when we are not working. Here in the equatorial upwelling zone, microorganisms grow well because of the extra nutrients that are brought to the ocean’s surface by upwelling (upwards movement) of water from the deep ocean. As a consequence, in certain depths of the water column, oxygen is consumed faster than it is supplied via circulation
