We Blogged It!
I received a short update today from Chief Tish. They were about 14 nm from the two “impossible to reach” moorings that they were trying to recover. She said, “We have made good time in what we thought would be difficult ice. Everyone is excited to recover them and finish the cruise on a happy note. All else is going well.”
Tish also sent a new batch of images from the ship. The zooplankton pictures were taken by Sanne Kjellerup and show the beautiful variety of Antarctic Ocean zooplankton specimens.
She also sent pictures of Tracer Team graduate students, Keliang Shi and Peng Yi. The Tracer Team PI is chemical oceanographer Ala Aldahan (not onboard). This project is using isotopes of iodine to trace Pacific and Atlantic water masses in the Southern Ocean.
If all went well with recovering the moorings, the NBP should be on its way to McMurdo!
More soon ☺
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.
