December 6th, 2007 andrea
I was able to interview Ken Mankoff from the Center for Climate Systems Research at Columbia University here at McMurdo. He is developing the edGCM (Educational Global Climate Model). You can hear more about it in the interview below:

Marianne Okal of UNAVCO
December 2nd, 2007 andrea
Yesterday I had the opportunity to meet Marianne Okal, who through her work at UNAVCO, builds gps systems to support field science work. UNAVCO maintains GPS stations in fixed locations around McMurdo that serve to calibrate roving GPS systems at field sites. Because GPS information from satellites can be subject to weather and electrical conditions, UNAVCO’s fixed base systems help to provide more accurate information by constantly comparing GPS readings at the fixed bases to their known locations, and then error correcting for all GPS systems in the area.
Marianne showed me some GPS systems she had been building for the field, and some visualizations of GPS data from a survey on a glacier shown here.

Science at the Crary Lab
December 2nd, 2007 andrea
Yesterday Crary Lab supervisor Cara Sucher gave me and another McMurdo newbie a tour of the Crary Lab. What is unique and exciting about Crary is that scientists of very different disciplines work side by side in one building, and sometimes even share the same lab. My studio is also located in Crary, and it is great to be in such close quarters to the scientists.
Crary is divided into 3 ‘stages’. The first stage contains several biology labs including temperature controlled labs that look like large meat lockers. In these labs, specimens from the field are analyzed, and because transportation of specimens can be so difficult, a large amount of lab work is done in these labs.
The second stage contains geology labs, and is currently filled with scientists from the Andrill project, the deepest earth core drilling and paleoclimate analysis that has ever been done.
The third stage contains tanks for living specimens: fish, snails and other animals. Pictured here is a snail that has its shell inside. It looks like a yellow plastic toy, but when you hold it you can feel it moving, pretty amazing. Click the image for more pictures of the lab.

Questions from Molly
December 1st, 2007 andrea
My colleague Steve Gorelick sent me an email. His daughter Molly had some questions for me. Molly, thanks for the questions, I will try to answer them as best I can here:
Molly: What did you eat for dinner? Fish?
Andrea: Yesterday I had fresh fruit and vegetables and a wonderful tempeh noodle dish. We eat in a big dining hall and can choose from a variety of dishes that a group of chefs create. All the ingredients are delivered via plane (in fact, I think we flew in on the same plane with the fresh fruit and veggies I had for dinner).
I heard that sometimes when the weather is bad, especially in winter (it’s summer here now, the opposite of the Northern hemisphere), the planes can’t fly in. Then, the residents of McMurdo hope for the weather to clear soon to get fresh fruit and vegetables.
There are a lot of fish living under the ice, and Weddell seals and penguins, and Antarctic explorers would eat these animals in the past, but because the ecosystem is so fragile, the wildlife is protected and can’t be killed for food. But, there are a lot of scientists studying the wildlife around McMurdo, and soon I will post pictures of some of the animals they are studying in the labs here. The photo here is from a historical hut at Scott Base, to give you an idea of what people ate when the base first opened almost 50 years ago.
Molly: What are you doing now?
Andrea: I am in the Crary lab working on my computer, I spent the afternoon touring the labs and meeting and talking with scientists and tonight I will hear a presentation from the Andrill group, a team of over 75 geologists drilling a core out of the earth here in order to study past climates.
Molly: What time is it?
Andrea: It’s 18 hours later here than in New York, because the flights originate from Christchurch, New Zealand, McMurdo operates on New Zealand time. Since all the lines of latitude meet here, I had heard that the entire continent operates at the same time, but this is not true, most bases operate in the time zone of where most people and supplies fly in from.
Time is a little strange here in the summer, though, because the sun is out all day and night. It was hard to get to sleep last night with sunlight streaming through the window. In the winter it is dark all day and night.
Molly: Are you out there with any penguins?
Andrea: There are two types of penguins that live near McMurdo, Adelie and Emperor penguins. I haven’t seen any yet, but I have talked to people here who have. I have seen a bird that is common here called a Skua, a kind of brown seagull. The Skuas know that people in McMurdo often have food and can sometimes be very aggressive if you happen to be carrying a sandwich!
Molly: How would we find you on the map? What are your coordinates?
Andrea: If you go to the google world map on this site (link under the Antarctic map), I have made a marker that indicates McMurdo’s latitutude and longitude. Unfortunately, google maps doesn’t have a lot of detail of this part of the world, I recommend looking at the link Sha Sha provided for more detailed images.
