I must say the 40 people who I have been working and living with here for the past few weeks are some great folks. Everyone has been extremely accommodating and patient. It's obvious to me they love their jobs and this program. I've joked that I wouldn't mind relocating my office here next season, and the longer I'm here, the more I seriously think how great that would be.

Birding at Palmer Station
I went birding with the research team that monitors the various seabird populations near Palmer Station, from Adelie penguins to giant petrels. The expedition leader here is Donna Fraser, who has been coming down to the Ice for years. She became fascinated with the giant petrels, a large scavenger that nests throughout the islands here, and went on her own quest to study the bird population. Through patient observation and perseverance, she was able to habituate the birds to her presence on Humble Island, where the team currently monitors 27 nests. They measure the bills of the chicks and weigh them every couple of days or so, and also place transmitters on the adults to track their foraging patters.
I went with the team yesterday to watch them at work. They spend long hours hiking and climbing around the islands to survey the nests, some of which can only be reached by a hard scramble up nearly sheer rock faces. The treks are made even harder because they try to avoid trampling the moss on the island, so you're rock hopping most of the time, watching your feet on the ankle-twisting rocks while trying to avoid stumbling on the nests, which seem to appear suddenly despite the large size of the birds. I was pretty spent by the end of the day, particularly after our final climb up a cliff on DeLaca Island to check on just one nest.

Another Penguin Video
Everyone loves penguins, right? So here's a little better video, I think, of the penguin colony on Torgersen Island, which is only a few minutes' ride from Palmer Station on Anvers Island, in the northern part of the Antarctic Peninsula.
No music this time, just the braying of the penguins and my own rather anemic interjections ... one qualifier, however: I mention that the colony has shrunk due to climate change but I don't offer any explanation in the video.
The short story: The ambient temperature has warmed significantly. In addition, the deep ocean water that comes up on the shelf is also much warmer. The changes have reduced the duration of sea ice in the region, which is not only a key habitat for the penguins during the winter but also for its main prey, the shrimp-like krill. All this means that chick survival and recruitment to these colonies has been drastically reduced.
I'll have more on this story when I go out with the seabird researchers next week.
There's also some new articles on The Antarctic Sun Web site, including a couple on different aspects of this trip.

Touring Palmer Station
Most of my blogs and photos thus far have been on the wildlife and scenery here -- and justifiably so. But I will try and do a few on some of the facilities and society here at Palmer Station, which is so much different from the other two U.S. Antarctic Program stations at McMurdo and South Pole.
It's by far the smallest science base of the trio, and we are currently maxed out with 45 people. Ironically, it gets the most visitors by far in terms of tourists. The station typically hosts 12 ships per year, as well as the occasional private yacht or sailboat. It's great outreach for the science program, allowing people to see the facilities and meet the researchers personally. I talked to a bunch of tourists over the last week or so, and all of them were impressed by the station. They get a tour of the station, the highlight being the store:
At the end of the tour, the groups are led to the lounge/galley, where they can chat with station personnel and chow on brownies (apparently famous enough to have been mentioned in the Lonely Planet Antarctica) and have tea or coffee, and grab some brochures as well.
After a day of working and playing tour leaders, the station staff has a great place to hang out. The local pub is BYOB, and everyone contributes very generously to the general stash:
In addition to the recent tourist ships -- whose passengers included Buzz Aldrin -- we got a visit from the RVIB Nathaniel B. Palmer, one of the two research vessels for the National Science Foundation. Stiff sea ice on the east side of the peninsula has rebuffed their efforts to go very far south, so they're on the western side trying to come up with a new plan, though they think they can fly helicopters across the mountainous peninsula to do some of their original work.

Boating Around Palmer Station
Here's a short 55-second video of boating around the local area and visiting Torgersen Island, home to mostly Adelie penguins, though the lone penguin in the video you'll see is actually a gentoo, a larger subantarctic species that is "invading" territory traditionally held by Adelies, who are struggling in the warmer climate here. The island is less than 10 minutes away by Zodiac, inflatable boats with outboard motors that are used for science and recreation here. Access to many of the islands is limited to scientists. In fact, half of Torgersen is actually a preserve that tourists are now allowed to be on. However, one of the birders -- scientists studying the various seabird populations here, including the penguins -- told me the impacts of tourism are pretty low when well managed.
At the end is a leopard seal on an ice floe, where they can often be found lounging after enjoying a tasty meal of penguin.

On the Glacier
One of the highlights of visiting Palmer Station is to hike up the local glacier that sits behind the research base. It's less than an hour's slow hike to the top, which offers commanding view of the harbor, nearby islands and mountains that rise up sharply from sea level.
It's a fairly easy hike, though the walk through the "backyard" right behind the station is a tad treacherous -- a rock-strewn maze of ankle-twisting debris. I came across a bizarre corpse of a what appears to be a brown skua. It's entire chest cavity empty, while it's head other extremities were still well preserved.
The glacier itself seems to be in poor shape. Long-time residents will tell you it's retreated mightily in the last couple of decades, and the face I walked was crusty, flaked with delicate ice crystals that easily dislodged and flew away in the wind, making a musical twinkling as they skipped across the irregular surface of ice. There were several skinny but long cracks that you could hear water running through, as if someone had left the faucet running underneath the ice.
A black flag line marks off the more unstable parts of the glacier, though I wonder how often that trail now moves. In recent years, it's not unusual for new islands to be discovered as the glacier retreats in other areas, revealing that what people had once thought were one stretch of land to in reality be split by open water.
A few pictures from the afternoon hike:

Boating at Palmer Station
I'm finally back at Palmer Station for the duration of my time in the Antarctic. My plan for my first night here was to hike the glacier behind the station -- a towering wall of ice that has been increasingly receding as the area continues to warm.
But then some folks put together a little boating expedition to nearby Torgersen Island, a rocky island less than 10 minutes away from the station by Zodiac. It's home to an Adelie penguin colony, a fact you can smell as well as see as you hit the downwind approach. Nearby at Elephant Rocks, brutish elephant seals slammed into one another like mammalian versions of sumo wrestlers ...

Palmer Station
The dreaded Drake Passage was more like Drake Lake.
I arrived at Palmer Station, a scattering of buildings clinging to the coast of Anvers Island along the Antarctic Peninsula, on Dec. 3. The middle of the four-day crossing is infamously rough between the tips of South America and the peninsula because of the Antarctic Circumpolar Current, the world's largest ocean current, which circles the continent completely unimpeded by land. High seas and lying low in your bunk are the norm, I'm told. But Poseidon or whatever marine deity that rules these seas was kind to us, and after a day of precautionary seasick meds, I enjoyed the trip, getting to know some of the scientists and crew aboard the ship.
The captain of the Laurence M. Gould, a stick-thin and amiable fellow named Joseph Abshire, said it was one of the two or three calmest crossings he's seen out of 40 or 50 clips across that stretch of sea.
It's a surprisingly young bunch onboard, recent graduates and postdocs, with a few polar veterans, led by Hugh Ducklow, chief scientist who has been working down here since 1994. It's mostly Americans, though the postdoc, an infectiously cheerful lady named Kim Bernard, is from South America, and the chief engineer, a sort of silent, strong type, is from Portugal.
While uneventful in terms of high seas, we enjoyed some wildlife en route, including a large pod of Commerson's Dolphins in the Straits of Magellan. The black and white dolphins looked a bit like mini orcas, gliding and slicing through the rolling waves during the long twilight. Sadly, no photos.
However, lots of other picture opportunities, as you'll see below, and plenty more to come, esp. with nearly 24 hours of daylight. Technically, the sun sets for about two hours or so right now, but it's always daylight out. Not a lot of time for blogging, as the science cruise is preparing to leave, and I'll be on the ship for another day or two to see most of the operation in action, then back to Palmer Station for about a month.
