A Friendly Penguin Wave (Goodbye?!)

Image
The 2012 Weddell seal science season for our crew is just about wrapped up, sadly enough.  Our camp has been pulled off the ice, and we've been busy scurrying around, returning equipment and gear, cleaning and washing everything.  We leave in 7 days!  Aaack!

It has been an incredible season with a lot of valuable data collected by a solid crew.  There are literally hundreds of people to thank for making this project a success...a substantial proportion of them working as support staff here on station.  Nothing would be possible without their wonderful and friendly support.  And I certainly can't forget to thank YOU (if you are a tax-paying American citizen).  Because this project is completely funded by the National Science Foundation, YOU are paying for it.

This may be my last season here on the ice, and so I hope you have enjoyed some of my attempts to capture not only the project, but also the incredible scenery and majesty of this place.  I may have a few more posts left i…

The Pack Ice is In

White Islanders

About 60 years ago, the sea ice melted so far back into McMurdo Sound, that it began melting and breaking off the ice shelf all the way back to an island, called White Island.  Previous to this event, no seals were found at White Island, but the melting allowed several (estimated to be three females and two males based on an ongoing study by Tom Gelatt) seals to get to the island and take advantage of its underwater resources (food!).  But the seals did not prepare for the fact that they would never be allowed to leave again.  The next year, and every year after, even to the present time, the sea ice has not melted or broken out to White Island, and the ice edge has always been maintained at a distance too far for the seals to make it out.  So the seals have remained, and they have kept breeding.  Each season, we take a helicopter twice to White Island to tag any pups that are born, collect genetics samples (a tiny tissue sample from their flipper), and assess their status.  Since it …
