Engineering team completes ambitious Antarctic expedition in the 'deep-field'
Date:1/15/2012

p>Andy Tait, Advance Party Member and Hot Water Drill Designer / Engineer says, "Lake Ellsworth is extremely remote, cold and hostile ambient temperatures dropped to -35C and with wind chill they dropped further still making living and working on site a physical challenge. We deliberately located the equipment over a kilometer (1.7km) from the drill site to protect it during the harsh Antarctic winter. We will move it to its final position and set up the rig ready for drilling in December.

"Severe winds and the extreme environmental conditions of the area made it vital that we spent a number of days winterising the equipment. Windblown snow will partially bury the equipment and this area of Antarctica is so vast that it would be difficult to find it again without the GPS locators we fitted at the corners of the site. Going back to live there for three months in November will certainly be an experience!"

Chris Hill, Advance Party Member and Lake Ellsworth Programme Manager says, "This is a major milestone for the programme and we are delighted that our complex logistical operations were a success this season. Working within the short Antarctic summer season adds pressure to our time on the continent, which is why we had to plan two stages of the programme. The drilling season is nearly upon us, and we still have a long way to go before we can access Lake Ellsworth, but the success of the Advance Party this season certainly puts us in a good position for November."

The Lake Ellsworth Programme Principal Investigator, Professor Martin Siegert from the University of Edinburgh says, "The completion of this stage of the mission is a welcome one we are now one step closer to finding out if new and unique forms of microbial life could have evolved in this environment. The samples we hope to capture from Lake Ellsworth will be hugely valuable to the scientific community. This year we will complete and test both the water sampling probe and
