Weddell Seal Expedition: Tagging Weddell Seals
Posted February 22nd, 2009 by PatrickRobinsonPatrick Robinson at the Eastern Weddell Sea, Antarctica-- The Weddell seal tagging is off to a great start. We have been quite busy over the past 2 days and have already deployed 6 of the 10 tags! This is how we do it: After we have located a seal from the bridge of the ship, we assemble a team of people to go out onto the ice. We don our cold-weather gear and bring our tagging supplies to the main deck of the ship. To get to the ice, we have to be lowered by a crane (I will admit, this part is actually quite fun!).

Weddell Seal Expedition: CTD casts
Posted February 13th, 2009 by PatrickRobinsonPatrick Robinson at the Eastern Weddell Sea, Antarctica-- The main purpose of this RRS Shackleton expedition is to study the oceanography of the Weddell Sea. To do this, researchers from the British Antarctic Survey deploy instruments on mooring lines (see previous blog posting), but also complete point samples by lowering instruments deep into the ocean from the ship. The CTD (conductivity, temperature, depth) recorder as well as current profilers are the basic tools of oceanographers and provide information about a profile of the water column.

Southern giants have been tagged!
Posted February 12th, 2009 by LuisHuckstadtLuis Huckstadt at Punta Arenas, Chile--We are finally back to civilization after a successful field season at Cape Shirreff, Antarctica. I'm happy to report that we accomplished our goal of deploying 15 satellite tags on southern elephant seals (see Cool Cousins). This work could not have been done without the great crew that helped us at the Cape Shirreff camp.

Weddell Seal Expedition: A Quick Stop in the South Orkney Islands
Posted January 26th, 2009 by PatrickRobinsonPatrick Robinson at Signy Island, South Orkneys -- We made it through the drake passage with very calm seas and have arrived at our first stop, a British research base on Signy Island (part of a small group of islands called the South Orkneys). We are dropping off a few biologists and will return for them after the oceanographic and seal-tagging work in a few weeks.

Weddell seal expedition: crossing the Drake Passage
Posted January 25th, 2009 by PatrickRobinsonPatrick Robinson in the Drake Passage, Southern Ocean -- After a spectacular sunset, we set sail yesterday and are currently halfway to Signey Island, a British research base. The seas are very calm (a mere 6 - 8 ft swell), but several folks on board are tucked away in their bunks due to motion sickness. The rest of us have been using this transit time to prepare instruments and help the crew cook and clean. Yesterday I peeled ~80 pounds of potatoes!
Here are a few photos from the past couple of days:
