4:19 p.m., Feb. 22, 2008--A daring mission in 1931 to explore the Arctic in a submarine named Nautilus, and a recent underwater expedition to rediscover the scuttled vessel, will be the focus of the next lecture in the University of Delaware's William S. Carlson International Polar Year Events, set for 3:30 p.m., Friday, Feb. 29, in Memorial Hall.

1:39 p.m., Feb. 12, 2008--Capt. Lawson Brigham, who sailed to the polar limits of the global ocean on a voyage from Antarctica to the North Pole, will join a celebrated group of adventurers when he signs the American Geographical Society's Fliers' and Explorers' Globe at 7:30 p.m., Tuesday, Feb. 12, at the University of Delaware's Louise and David Roselle Center for the Arts.

5:05 p.m., Jan. 17, 2008--As the globe turns, you see their names--the autographs of an elite group, the world's foremost explorers and aviators. There's the signature of Amelia Earhart, the famed aviatrix; Robert Peary and Roald Amundsen, first to reach the North and South Poles; Sir Edmund Hillary, the first to scale Mt. Everest; Neil Armstrong, the first to set foot on the moon. One legendary pioneer after another.

3:47 p.m., Jan. 9, 2008--Being away from home during the holidays is always hard, and this is especially true at the literal end of the earth, the South Pole. Here, satellite connectivity for Internet and domestic phone calls is available only eight hours each day. This community of 250 people, living at 10,600 feet on the world's largest ice cap, braving -20 degree summer temperatures, has developed a unique camaraderie that may be as friendly and comforting as this location is harsh.

4:17 p.m., Jan. 8, 2008--For 25 UD students and their two professors--Jacob Bowman, associate professor of entomology and wildlife ecology, and Jonathan Cox, supplemental art faculty--Friday, Jan. 4, was not a typical first day of class. At 4 p.m., they boarded a plane at New York's JFK airport heading for Argentina and Antarctica as part of the University of Delaware Winter Session Study Abroad Program.

a.m., Dec. 19, 2007--We left South Pole Station yesterday on time. I was lucky again to get to ride in the cockpit of the C-130 all the way from Pole (NPX) to McMurdo (MCM). I think I now have more flight time in the cockpit of a C-130 than I do in a Cessna! I really need to remedy that and finish my pilot license!

a.m., Dec. 17, 2007--When I first arrived here, we had temperatures of -40¡ or lower every day. During the last week, there has been a warming trend. The temperature has warmed to -24¡C, but the wind has picked up. Yesterday, the winds were at 26 knots. All of the pictures I have sent so far showed blue skies, but add 26-knot winds and you have a whiteout!

a.m., Dec. 11, 2007--The routine for leaving South Pole calls for checked baggage to be packed and available for collection in the hallway of the station at 7:30 p.m. the day before scheduled departure. This year, everything went according to schedule, which is not always the case....

11:15 a.m., Dec. 7, 2007--Most of you have read about IceCube or IceTop earlier in this series. For those who haven't, we are building the world's largest Neutrino Telescope here at the South Pole. Neutrinos are incredibly hard-to-detect particles, so we need a really big detector. IceCube, when finished, will use a cubic kilometer of South Pole ice to capture the light signal left by neutrinos that have passed entirely through the Earth. Neutrinos point directly back to their source, so they will help us map the Northern sky in ways that have never been seen before.

11:15 a.m., Dec. 1, 2007--Editor's note: Over the next few weeks, with support from the National Science Foundation, a team of University of Delaware researchers will be at work in one of the iciest, coldest, most austere places on the planet: South Pole, Antarctica. Currently stationed at the South Pole are UD researchers Thomas Gaisser, Stoyan Stoyanov, and James Roth of UD's Bartol Research Institute, who are working on the IceCube neutrino telescope.

9:07 a.m., Oct. 8, 2007--Michael O'Neal, an assistant professor of geography at UD who recently returned from a two-week field trip studying glaciers in the Cascade Mountain Range, describes a typical day of research: A five-mile vertical hike kicks things off. Careful note-taking fills most of the daylight hours. The hike back to camp (at an elevation of 3,000 feet) completes the cycle. And at the end of the trip, the thoroughgoing data will be inconclusive. Two weeks in the life of millennia-old glaciers is a very short span, after all.

3:49 p.m., July 13, 2007--Three scientists--two with close ties to the University of Delaware--lived in a frigid ice camp this spring as part of a $1.4 million National Science Foundation project they have dubbed SEDNA, for Sea-ice Experiment: Dynamic Nature of the Arctic.

3:15 p.m., July 13, 2007--University of Delaware scientists played key roles in a National Science Foundation-funded spring project to better understand the motion and deformation of Arctic sea ice through fieldwork, satellite imaging and computer modeling.

2:34 p.m., June 15, 2007--James Roth, a senior electronics and instrumentation technician in UD's Department of Physics and Astronomy, recently completed his fourth season in Antarctica, working on UD's “IceTop” project. His blog from the South Pole on Jan. 15 provides insight into what it's like to live and work on the harshest continent on the planet.

11:22 a.m., June 1, 2007--UD marine scientist David Kirchman has sailed among glaciers, walked with penguins, swum in the same icy waters as polar bears, and seen ice-covered mountains so majestic they've taken his breath away. He is a veteran of scientific research cruises in the freezing waters of both the Arctic and the Antarctic, with more exciting voyages ahead in the International Polar Year.

3:18 p.m., May 23, 2007--"IceCube" is a gigantic scientific instrument--a telescope for detecting illusive particles called neutrinos that can travel millions of miles through space, passing right through planets.

4:45 p.m., March 2, 2007--The world is marking the fourth International Polar Year from March 2007 to March 2008, providing a time to reflect on the importance of the frozen reaches in the Arctic and the Antarctic to the health of the planet and to consider the implications that the changing climate in those regions may have around the globe.

9:52 a.m., Dec. 21, 2006--Two University of Delaware professors are co-principal investigators in a National Science Foundation (NSF)-funded project to understand how changes in temperature and nitrogen deposition affect tundra ecosystems.
