Updates and photos from the field for Monday January 11

Monday, January 11th, 2010

From Ellen Mosley-Thompson: “We are doing well here. Thursday, we sent 21 more ice core boxes to Rothera for storage in the freezers. We have now drilled slightly more than 50% of the ice that we expected to drill.  We are changing to the thermal drill today.  It should take us roughly 12 days of drilling to reach bedrock if things go well.  Of course there are always challenges and surprises – plans are only made with the realization that they are likely to change. We are very optimistic that we will recover the Em drill that is [stuck] at about 140 meters in the Core A hole.  We do not plan to attempt to extract it until all the other projects are completed.

To date, we have sent 54 boxes of ice cores back to Rothera for storage in a freezer until the Nathaniel B Palmer (the NSF ice breaker) comes to pick them up and transport them to Port Hueneme, California. From there, the ice will be shipped in a freezer truck to The Ohio State University.”

Ice Core Team now in the field

An update from the field:
“The group moved by Twin Otter from the English base of Rothera to the remote camp of LARISSA Site B on the glacier. Working in the polar night they installed the camp. They recovered, by using a ski-doo, some equipment that was left from a previous flight 15 km from the camp.

They started to drill the ice field and they quickly reached 140 m of depth. Unfortunately, the drill was lost shortly after because the cable got broken. Now they are trying to get the spare drill from the Rothera base and they hope to start to drill soon.”
