We're now heading to the South Orkney Trough to deploy a mooring, adding to five already there looking at outflow of bottom water from the Weddell Sea. Dense water is formed around Antarctica (especially the Weddell Sea) due to it getting very cold and brine rejected when sea ice is formed. This flows down the continental shelf and around the bottom of the world's ocean (except North Atlantic). Being below 2000m it is not sampled by autonomous floats so these mooring and the deep transect we will do afterwards are still the main way the properties, and any changes, are monitored.
Wandering Albatross. One of these birds was ringed so will try to find out the details.
