The blogs have been a bit spotty lately, as I was busy getting ready to leave Palmer Station, which I did on Feb 3, followed once again by the four-day crossing of the Southern Ocean between the Antarctic Peninsula and South America. I will have more to say about my time at Palmer, along with more pics, but that will require more time than I have now at this hostel Internet cafe (where it costs about 50 cents for an hour of surfing).
We returned to Punta Arenas early on Sunday, Feb. 7. Then followed a mad dash by me to try and secure a bus the next day for Ushuaia in Argentina, which competes with PA as the southernmost city. Ushuaia is farther south but smaller, so you decide ...
Miraculously, there was one ticket still available, so I booked a round trip for about 60,000 pesos -- about $110US. It´s about a 12-hour bus ride, and after yesterday I found out why ...
I got to the bus station in plenty of time, and it turned out there were two buses going to Ushuiaia, so I showed my ticket to one guy and he told me to get on the other bus. Of course, five minutes into the trip, when this fellow was going around checking seats, he told me that I was on the wrong bus and would have to transfer at some point. They were essentially caravaning. That wasn´t a big deal, as we ended up having to take a detour on some dirt road because of some sort of protest involving burning tires piled across the road to the airport. Fisherman protesting for more money apparently.
The trip was largely uneventful but the border crossing was what I would generously describe as chaotic, and it must have taken us close to two hours to exit Chile, drive the few kilometers to the Argentine border and enter the country. It looked like Argentina would be easy, as we got in quickly and got the passports stamped. Back on the bus, they told us to get back off and run our luggage through. Apparently the x-ray machine is usually `broken,´ but according to one Spanish guy on the bus, the immigration official didn´t like the bus driver or something along those lines, so we had to go back ... funny thing is no one was making sure we went back into the building, so some people didn´t even bother. And I don´t think anyone was actually watching the machine monitor, located away from where everyone just grabbed his or her bag and walked back out.
Got in around 930 p.m. in rain and light fog. The drive was beautiful for the last couple hours and actually reminded me of Colorado, esp. Lake Dillon, with mountains rising steeply up around a lake. The rest of the trip was more like eight hours driving through the foothills around Golden. Instead of wild deer or elk running acorss the road there were wild llama. And many, many kilometers of sheep farms, which eventually gave way to cattle ranches in Argentina, famous for it beef (and love thereof).
Going to try and do a little boat tour today on the Beagle Channel. First impression is that Ushuaia is a pretty touristy town, with two Irish pubs and lots of outdoor gear shops. Still, a nice break from the Ice and windy, dusty PA. The town sits right on the harbor and then climbs up away from the water like San Francisco. It is the main jumping off point for tour cruises to Antarctica, and ran into one boat crew last night, including a woman who has been to both Palmer and McMurdo stations as an expedition leader. The latter is particularly interesting since there´s really only one ship, the Russian Kapitan Klebnikov, that actually makes it to McM. I think she´s also friends with a guy I worked with at South Pole in the summer.
It´s a small world here at the bottom of the world.

Whale Watching
Yesterday was my second to last full day at Palmer Station. Technically, it was a day off because we worked on Sunday, but had a lot of work to do to get ready. I initially turned down an opportunity to go see humpback whales playing near the station, but when a second boat was organized, I decided to jump in, figuring by the time we go there the show would be over.
Thankfully I was wrong.
For about two hours we puttered around three humpbacks, which put on a quite a feeding display for us. There were even doing something called bubble feeding. Here's the wikipedia definition:
"A group of whales swims in a shrinking circle blowing bubbles below a school of prey in our case it was krill]. The shrinking ring of bubbles encircles the school and confines it in an ever-smaller cylinder. The whales then suddenly swim upward through the 'net,' mouths agape, swallowing thousands of prey in one gulp."
At one point we drove through a pink cloud on the water -- a cloud of whale poo, colored that way because of the pink krill (small crustaceans) that they eat.
A few pics and hilarious video (and, no, that's not me screaming like a little girl).
Mt. William on whale watching day. It's about 5,000 feet high.
The original whale tail.
Taking a gulp of krill.
We had lost sight of the whales and were stopped, when suddenly all these bubbles appeared around the boat.

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:
The view from the top of the glacier looking behind the station.

More Wildlife at Palmer
A beautiful day here at Palmer Station, Antarctica, on Friday begged for plenty of outdoor time. Here's a few highlights from the day. (Click on any image to enlarge.)
A closeup of a leopard seal on an ice floe. They look almost reptilian.
A wider view of a leopard seal, just floating nearby the station. Note the brown skua, another predator, sharing the space at the far right.
