Technically challenged....

My graduate advisor said on numerous occasions that he was an analog man living in a digital world. I have been trying to figure out a way to upload videos into this blog, and I finally made the decision to upload the videos into YouTube and then link to there.  So, finally, without further ado, below are two video links. The first is of my favorite Antarctic bird, the sheathbill, and the 2nd is a short video of a Wilson's Storm Petrel feeding at the outfall of Palmer Station. You can use your imagination as to what he may be eating....

Hopefully, the links work...

Guess what my favorite Antarctic bird is....

You probably guessed penguin, right?  Well, you are wrong!  My favorite bird here at Palmer is not Adelie, gentoo, or chinstrap penguin.  It's not the giant petrel (shown below)....
Young giant petrel.  I took this photo at dawn when we were leaving to go fishing, so it's a bit dark. 
Or the cape petrel or Wilson's storm petrel (photos and videos coming soon).

Sheathbill at Palmer Station
My favorite bird is the snowy sheathbill (Chionis albus), which is supposed to Antarctica's only land bird. They eat really anything they can find.  Many people call this bird the Antarctic chicken, and as you can see from the phot, they kind of look like a chicken.  Here at Palmer they can be found wandering around the station.

Back from fishing...

I went out on the boat fishing and was unable to post any updates from the ship. I will hopefully over the next few days put many new posts.
Me with a Dissostichus mawsoni.  The common name of this fish is the Antarctic toothfish. This is a young one; they can up to ~80kg, but this one was a mere 4.5kg.

Getting ready to leave Chile


Warehouse in Punta Arenas where we get our gear


Lots of options for Palmer Station attire
We are provided with all the cold weather and fishing gear that we need to wear in Antarctia.  At the dock there is a warehouse where we get a dufflebag with what we need and get a chance to try it all on to make sure it fits.  When we return to Punta Arenas we return it back to the warehouse.  We get long underwear, winter boots, coats, rubber boots, gloves, pants, and jacket for fishing, hats, gloves, and my favorite Carhartts!


Ooh-la-la... Kristin O'Brien checking out the latest in Palmer Station fashion.

Checking out our clothing

 The research vessel that we use is the Laurence M.Gould (or LMG) , which is named after the explorer Laurence McKinley Gould who was a member of Admiral Byrd's expedition to Antarctica in the late 1920s.  The boat was built in 1997 by the Edison Chouest Offshore out of Louisiana, and it replaced the Polar Duke. During my 1997 field season I was on the Polar Duke, so I have been lucky enough to be on both vessels. The LMG is about 230 feet in length and quite comfortable (if you are fortunate enough not to get seasick!). Pictures will be coming... so stay tuned.

Skipping ahead to Antarctica...

I still have a lot of pictures and information to post about the ship and traveling down to Palmer Station, but tonight I'm going to show some photos that I took on our walk up the glacier. Behind Palmer Station is a glacier that you can hike up, as long as you stay within the flagged area. Outside the flags are crevasses, which you really don't want to fall into.  To walk up the glacier you sign out on a board in the main hallway with the people who are going, where you are going, time out and the time you expect to get back, and you take a radio with you.  Anyway, Kristin, Lisa and I hiked up the glacier, which takes about an hour to walk up, and it's icy so we put Kahtoola microspikes that stretch over your boots and keep your from slipping on the ice, after all we are walking on a glacier.  Here's a top view of my feet, showing the microspikes on my boots, but it's not that good of picture.

It was a gorgeous sunny day and the temperature was probably around 20-25 degrees Fahrenheit (although I could be off), cold, but not super cold.  Below is a photo of Palmer Station I took when I was near the top of the glacier.
Can you find Palmer Station?
It has been cloudy around the station; some days it rains, other days it snows, and the other day it hailed.  The last time I was down here was in 2001, and over the past 13 years there are definite indications that the Antarctic Peninsula is warming. I'm going to ignore the decline of penguins around Palmer, and the issues we are facing keeping the water cold enough for our icefish in our aquarium lab (yes, the water around Palmer Station that we bring into our aquarium is on the verge of being too warm to maintain our fish. In the next few years we may need to use chilling units to keep the water at ~0.8 degrees Celsius). Since 2001, which was the last time I was here, glacier has retreated away from Palmer Station leaving a rocky "backyard", that is A LOT larger in size than what it used to be! The Antarctic Peninsula is warming extremely quickly causing loss of glacier ice and ice shelves (http://www.nature.com/ngeo/journal/vaop/ncurrent/abs/ngeo1787.html).  The warming of the ocean by even a few degrees has the potential of wiping out the plants and animals that cannot adapt to rapidly changing temperatures. The Adelie penguins rely on ice to serve as floating docks that they can rest on and then enter into the water to feed.  Since 1974 Adelie penguin populations along the western Antarctic Peninsula have declined by 84% (http://pal.lternet.edu/sci-research/transformational_science/). I have seen a few Adelie penguins on my way down this time (no pictures yet), but not as many as in previous years.

And on that note, here are some photos from today.





Rubbing the toe for good seas!

Main square in Punta Arenas.
 The main square in Punta Arenas is really beautiful.  Some of the trees have wicked huge trunks!
Walking to the square.
Large tree
























In the square is a monument to Ferdinand Magellan, the explorer after whom the Strait of Magellan is named. Legend has it that if you rub to toe of the native you will have smooth seas, and when you cross the Drake Passage you need all the help you can get!  Rubbing the toe may also give you good luck, or ensure that you will return to Punta Arenas. We rubbed the toe every time we walked through the square!

Rubbing the toe for a smooth crossing!
A closeup of the native's foot---- it's SHINY from all the rubbing!
Here's the entire monument with Magellan on the top.






Shackleton Bar


In the hotel in Punta Arenas there is the Shackleton Bar, obviously named after Ernest Shackleton, an Antarctic explorer.  Although he was not the first explorer to reach the South Pole (that honor goes to Roald Amundsen), he set out to cross the entire continent through the South Pole.  His ship the Endurance became trapped in pack ice and eventually sunk, so he did not complete he goal, but the story of he and men surviving and being rescued is an amazing story. Anyway, this bar in Hotel Jose Nogueira is a nice place to relax.  There's intricate woodwork and paintings that depict Shackleton's expedition, and here we enjoyed pisco sours. The image below does not do the bar justice.
