My internship at the Farallones involved many different fascinating studies, but one of my favorite studies were the seabird diets, as they really tie in the oceanographic aspect of marine ornithology. We are lucky to be able to live on this incredible, rugged island surrounded by the Pacific ocean and work with the birds that call it home, but sometimes it can be easy to take for granted just how strong the connection is that these birds have to the marine environment. By incorporating the feeding ecology of the seabirds, we are also considering vast topics like oceanic health, fisheries ecology, and climate change, much of which is still poorly understood. Taking part in studies that delve into this mysterious, watery realm is pretty exciting. Brandt’s cormorants also happen to be one of my favorite birds on the island – how could you not love the silky black birds that look like Muppets with long necks and giant feet, and whose eyes are a vibrant, deep turquoise?

Yesterday was a very exciting day – one of the highlights of this entire trip, and a new experience altogether! It was our highly-anticipated trip to Beaufort Island, which could only be reached by the Swedish icebreaker Oden. For our team, it was a chance to sample some very old penguin colonies. In fact, the oldest penguin molt layer was discovered there by Dr. Emslie 5 years ago. He collected feather and bone from this exposed layer on the northern end of the island, which turned out to be too old for radio-carbon dating – meaning that the remains were over 44,000 years old!
Beaufort Island was visible during our stay at Cape Bird. However, NSF helicopters cannot reach it because there is an expanse of open water, which they are not allowed to fly over (because in the case of an emergency, it would mean certain death). In 2005, when USAP had Coast Guard helicopters at McMurdo, flying to Beaufort Island was not a problem. But the Coast Guard helicopters are no longer coming down to McMurdo (they were extracted because they were needed for Iraq). So the only way to reach it now is by icebreaker, which limits field time severely (we were given a maximum of 3-4 hours on the island). It really is too bad, because Beaufort Island is a treasure-trove of paleoecological data, and has been studied very little to date.

So, Friday morning I woke up at 5 am to make it to the lab before our pick-up time of 5:45 am. The van came on time and delivered us, as well as Dr. Ainley’s team, and a couple of artists (a husband and wife) to the dock. There were 12 of us – 10 scientists and 2 artists. I was surprised, because I thought that many more scientists would be going. But it was only a select group. In fact, I almost wasn’t allowed to go – they would only allow 4 people from each team, and of course, I would have gotten left out. It might have had to do with the fact that Beaufort Island is another ASPA (Antarctic Specially Protected Area) and you need a permit to visit it (although every field site we visit is an ASPA because of the colonies). But Dr. Emslie wrote to the captain, asking that they allow me on as well. They said I could come along for the ride, with the exception that I would not be able to go out to the island (although once I was on the ship, they did agree to let me go…after all, how could they resist the charm of a young, aspiring scientist?)…I just am so happy that in the end, I got to participate despite the obstacles.
The mighty icebreaker Oden!
