Jan. 23 — The white dome covers the ice drill at Site Beta (photograph taken by Raytheon MPC Adam Jenkins).   Jan. 23 —One of the helicopts leaves Site Beta to return to the Palmer (photograph taken by Raytheon MPC Adam Jenkins).   Jan. 25 —Raytheon marine technicians Ross Hein (left) and Jeremy Lucke (right) guide the 6-meter jumbo Kasten core onto the Palmer's back deck in Barilari Bay.

Jan. 26 —The Palmer sits at the Rothera dock on Adelaide Island on the western side of the Antarctic Peninsula. (Picture taken from Rothera Point.)   Jan. 26 —The Palmer group takes a tour of Rothera facilities and around Rothera Point, scrambling over rocks and snow to stretch their sea legs   Jan. 27 — The ROV team captured an image of a small octopus in the Andvord Drift.

Jan. 27 — A brilliant sun star wanders into the ROV's view.   Jan. 27 — The seafloor in Andvord Drift proves to be a very productive area, hosting a range of organisms including brittle stars, bryozoans, hydroids, and anemones.   Jan 30. — In 1901-04, Captain Otto Gustav Nordenskjold led his crew to Snow Hill Island in Antarctica, which is located near our current position in the fast ice.

Dr. Eugene Domack snaps a picture of the Palmer in an ice floe on the helicopter flight to Cape Marsh on Robertson Island. Take notice of the path in the ice that the Palmer sliced through to make passage.   From left to right, Debra Tillinger, Sun Mi Jeong, Kim Roe, and Yuribia Munoz take sediment samples from a 6-meter jumbo Kasten core to be used for Dr. Scott Ishman's foraminfera analysis. In addition to sampling for foraminfera, the four students help collect sediment samples for a variety of analyses, including radiocarbon, diatom abundance, chlorophyll abundance, etc. (Picture taken by Montclaire State University professor Stefanie Brachfeld.)   A group of us headed out onto the ice floe on Saturday to collect short ice cores and to measure acoustic frequencies of moving ice bergs. National Geographic documented the experience.

With the GPS station and the helicopter in the foreground, the photograph shows a view looking toward Crane Glacier. (Photograph taken by Eugene Domack).   This rock, located at the GPS installation site, shows two sets of glacial striations. The striations (long grooves in the rock) demonstrate two flow phases in the movement of the glacier. The older flow phase went due east (to the right), and a younger phase went almost due south. The younger flow phase is associated with the plucking of the older striated surface. (Image and description from Eugene Domack).   Feb. 8 — Hamilton College professor Mike McCormick samples the mega-core in the glovebox. He keeps the custom-made glovebox under a nitrogen environment (lack of oxygen) in a 1-degree Celsius room to minimize chemical changes form occurring within the sediment while he samples the core.

Feb. 11 — From left to right, helicopter pilot Barry James, National Geographic writer Doug Fox, and Berkeley Geochronologist Dr. Greg Baclo arrived safely back on the Palmer on Thursday afternoon.   Feb. 12 — A leopard seal nabs an emperor penguin through a hole in the pack ice. One of the Palmer's engineers Johnny Pierce caught the action with his camera.   Feb. 12 — Raytheon marine technician Ross Hein and Lamont Doherty scientist Bruce Huber prepare the next link in the mooring as Dr. Eugene Domack looks on. Note the yellow conical sediment trap that bears the Hamilton logo. Photo: Kathleen Gravahan

Notice all the cracks on the top of the glacier as the ice slides down and breaks off into the bay.   Feb. 17 — View looking toward Larsen A of the retreating calving bays. Photograph taken by Dr. Eugene Domack during his flight to Cape Framnes on Wedensday.
