Chief Tish reports that they are near where they started in the Amundsen Sea and have likely completed their last planned station in the polynya. Looking at the image of the cruise track,Tish says: “...looks sort of like we tried to tie ourselves in a big knot!”
They are now heading north into the ice to try to recover a couple of moorings over the next several days. If possible, they may try to do another ASPIRE station or two. This and another MOCNESS deployment in the trough that connects the polynya to the deep, and they can call it a day! They plan to head to McMurdo Station on Jan 8.
Tish has sent some images of the MOCNESS operations. The images show Grad students Sanne Kjellerup and Rasmus Swalethorp working the MOCNESS and doing the subsequent lab work.Both students are working with PI Per Moksness, a Swedish larval ecologist. Tish has promised more images in the days to come as they begin to head for land ☺
Almost done -stay tuned!
Question of the Day
- What are Polynyas and why are they important to study?
Polynyas, are recurring areas of seasonally open water surrounded by ice.
Energy and material transfer between the atmosphere, polar surface ocean, and the deep sea in polynas provide polar ecosystems with just the right ingredients needed for high productivity and intense biogeochemical recycling.
Polynyas may be the key to understanding the future of Polar Regions since their extent is expected to increase with anthropogenic warming.
