Day 4: Wednesday 24 June 2020

Day four started with good news: We are going faster than expected due to the waves coming from astern and pushing us north! This means that we will reach our first station earlier than expected at midnight. So the serious work on deck will start soon.

The very first task will be launching a CTD to measure salinity and temperature at different depths, as well as to derive a sound velocity profile (SVP) for the whole water column – knowing the exact sound speed is important for the subsequent multibeam survey to correct the acoustic signals for their attenuation on their way down to the sea floor. If everything is in time, the multibeam survey will start around 1 am and should be finished by around 8 am, as this is the time when the plankton net will be deployed to catch those incredibly small but absolutely fundamental creatures.

 After a hopefully successful retrieval of the net, we will unleash the technical marvel – ROV Kiel 6000 for the first time! That is, if the weather is kind…right now, it looks like if that could be a limiting factor…

Heading for the big waves! The green triangle indicates our position. The other colours on this map show wave height - ranging from 0m in the pale blue areas to up to 9m high in the pink bits!
