Sampling techniques at sea

  Doing science at sea is more difficult as on land because it is not easily accessible. Therefore we needed some special devices to get an insight into the marine fauna. To measure different properties of the water body we used the CTD as he first device at every station. CTD stands for conductivity (salinity), […]

Kunst aus fast 4000 Metern Tiefe

Die bunten geschrumpften Becher mit einem normalen Exemplar in der Mitte.

Ein bisschen Spaß muss sein – also haben wir uns alle mit Begeisterung auf die von Nina mitgebrachten Styroporbecher gestürzt. Mit Wachsmalstiften und Edding waren der Kreativität keine Grenzen gesetzt und sehr ausgefallene Exemplare entstanden. In einem Netz gesammelt, wurden die Becher dann mit dem nächsten Großkastengreifer in eine Tiefe von 3862 m herabgelassen. Wieder […]

Der Sommer ist nun endgültig vorbei und damit findet auch die Zeit der Quallen langsam ein Ende. Die wohl bekannteste Qualle, die Ohrenqualle mit dem wohlklingenden Namen Aurelia aurita hat ihren Zenit längst überschritten und ist jetzt nur noch selten zu sehen. Dieses Jahr hat sie keine übergroße Aufmerksamkeit erregt. Jedes Jahr zur Quallenblüte bekommen wir […]

The Graveyard Shift

The problem with such strict and frequent sampling schedules on research vessels is that night shifts are inevitable; the time and financial restraints of such a cruise mean that you cannot afford to wait around at a station until the sun is up, the weather is favourable, and more importantly, the personnel are awake! The […]

Fütterung der “Forams” – eine langwierige Aufgabe

Charlotte Eich am Mikroskop.

Mittlerweile wurden mit dem Handnetz genügend Foraminiferen (Kammerlinge) gefangen, um sie an Bord für Experimente zu halten. Die Idee ist, zu sehen, ob die Foraminiferen auf ein zusätzliches künstliches Magnetfeld reagieren. Es gibt eine Kontrollgruppe ohne zusätzliches Magnetfeld und die Experimentalgruppe mit einem Magneten. Dafür kommt je eine Foraminifere in eine 50 ml-Flasche mit filtriertem […]

Now that Leila and Julia have already described life on board of the research vessel Poseidon, it’s time to talk about the ship itself. With its 40 years of travelling the seas, Poseidon is the Old Lady of the German research fleet. It is 60.8 m long, 11.4 m wide and has a draught of […]
