We have entered ice land finally and are now breaking some heavy but ‘rotten’ (sea-bear terminology for old and half-melted) ice. The ice damps the waves very effectively so now we can finally leave things unattended on tables etc, and trust that when we sit down to eat the chair does not suddenly decide to move away towards the wall.
Today we will conduct our first real station, we are revisiting the deep station North of the shelf break where we normally encounter unmixed water of the type we are interested in – so called ‘circumpolar deep water’ (or ‘CDW’). CDW is warm and salty and when it meets glaciers it melts them, so that is why we are interested in keeping track of it. At this first station there will be a lot of different equipment for chemistry, physics, and biology in the water and we will be here for close to 12 hours. After that it is Sweden’s first action point – to release two buoys that will sink to the bottom and measure bottom temperature for about a year.
All well on board, from 71 degrees South
