SEAT: Satellite Era Accumulation Traverse: Packing AgainDecember 21st, 2011 by Maria-Jose Viñas
Byrd Station (Antarctica), 10 December — The traverse team is preparing to leave and quite honestly, I am starting to get sad that I will not be going with them. We have all spent a lot of time together and we work well as a team, but I do have to get home. This will be my first time not collecting myself the field data that I need for my science, but the more I work with the team, the more certain I become that they will collect all the data necessary, if not more. Clem, Ludo, Jessica, Randy and Michelle are all excited to head out into the great white open.
Today, Clem and Ludo did a little science. They dragged the radar in a grid pattern around the ice core site from yesterday. This is important data because it tells us how representative the point where the ice core was drilled is of the larger area around it. When we compare ice core data to satellite data, we want to know if the larger area is homogeneous (similar) or not.
Randy made sure all the snowmobiles were ready and fueled to leave early in the morning. One of the choke leavers on a snowmobile broke off so he was working with the mechanic to get it fixed. Jessica looked at the electrical conductivity measurements from yesterday and took pictures of all of the log book pages to create a back up of the data. Michelle spent the day making sure all the gear was loaded well on the sled and that nothing was missing.
I spent most of the day watching the weather and talking with pilots. We cannot carry all of our gear on the sleds. A DC-3 Bassler aircraft is supposed to drop our fuel and ice core boxes and each camp site before the traverse. Due to the bad weather, the fuel cache has not yet been cached. So I have been talking with the pilots and rearranging the caches so the team can start out and not incur more delays. For now, the team will leave in the morning carrying two ice core boxes and one 55-gallon drum of fuel. This will allow them to get to the first camp site and drill. It will also give them enough fuel to get back to an established field camp if for some reason they don’t get any more fuel. They will not go to Camp 2 until they know the cache of fuel is there. Hopefully the cache will occur tomorrow or the next day so the traverse team will not be delayed.
Everyone will go to sleep early tonight. Because all of Antarctica operates on McMurdo time, the time of the day at Byrd does not match the daily temperature changes. The coldest part of the day, which would generally fall from 1 to 4 AM, is usually between 6 and 10 PM our time. The warmest time falls in the morning between 6 and 10 AM. Tomorrow the team will get up at 5 AM and leave around 6 AM to take advantage of the warmest part of the day. By 6 PM they hope to be cooking dinner and in their warm tents.
I can tell the team is ready to go because this morning they were complaining about how warm their tents were, a quick adjustment from the first cold night in the tents. Everyone also took advantage of the last day in camp to take a few pictures.
