Video from the NEEM borehole

On July 1st. 2011 scientists at NEEM managed to film the journey of the drill down through the 2538m deep ice core borehole. The 20 sec. video clip that was sent out of camp shows the deepest part of the 2538m deep borehole.

Watch the video clip from the bottom of the 2538m deep NEEM borehole

The video clip that shows the approach to the bottom of the NEEM borehole at 2538m depth in the Greenland ice sheet, was met with big enthusiasm from the scientists involved in the NEEM ice core drill project.

It is the first time that a video camera has been mounted to the drill at the deep ice core borehole. The video made it possible to get a very clear picture of the bottom of the borehole.

The physical conditions at the bottom of the NEEM borehole: Temperature -3 C and pressure 220 bar.

“We were astonished to see the quality of the images and how clear the borehole fluid is”, says Jørgen Peder Steffensen, associate professor at Centre for Ice, and deeply involved in the planning of the NEEM ice core drill project.

Use of a video camera opens up for new possibilities within ice core drilling

The video camera will aid the scientists in their attempts to drill even deeper into the debris laden bottom ice to obtain samples of basal material.

In the future, the camera will also be a help in improving drilling techniques and aid the scientists in drilling replicate cores by making diversion drilling at depth.

(The field diaries are sent out of camp all through the field seasons 2007 – 2011)
