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.




And a few more pics.


From the science cruise. This is a CTD rosette. The bottles collect water samples at various depths, while it also carries instruments to measure different ocean properties such as temperature and salinity.
