Marguerite Bay area

The first week of the voyage has already passed and science operations have begun, which means the ship is a hub of activity and work knows no time limits! Having been on a ship in the Southern Ocean, 24 hours of daylight can be good thing. It can also play games with your biological clock ☺

In the last post I mentioned that there were 70 people onboard the Palmer. Here’s the breakdown of who’s on board: 34 scientists (24 NSF grantees and 10 Swedish Polar Research grantees) and 12 Raytheon technical support personnel. Twenty-four are ship’s captain and crew.

Projects on this cruise include ASPIRE), IPY/ASEP Mooring Recovery, Invasive Crabs, and Iodine isotope distribution (SPRS). As the science operations unfold, I plan to explain more about each team and their work.

At this writing, the Multibeam and continuous underway sampling are operational. The first five days of science are devoted to the Invasive Crab Project. Project PIs are Rich Aronson, Jim McClintock, Per-Olav Moksnes, and Jon Havenhand. The Crab Team’s AUV Camera has been successfully deployed and good images are being collected! The CTD has also been deployed to a depth of 1000m, and the MOCNESS has been deployed 4 times. I hope to have images of people working soon!

Tish reports that the Captain and crew of the Palmer have been very supportive of the science, and she looks forward to an exciting and successful expedition!

BTW, an article in Nature about ASPIRE has been published. You can see it at: http://www.nature.com/news/2010/101129/full/news.2010.638.html?WT.ec_id=NEWS-20101130

Thanks to those of you who have sent in comments to the website, especially family of those onboard! Keep checking in for the latest news :)

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.
