Position: 88° 41.5' N, 64° 21' W, temperature - 30° C, air pressure 1008 hPa, wind 10 knots from ENE. Ice drift 0.2 knots toward south. Attempted to recover the ADCP. Drilled a hole 2 meter away from the wire to 4 meter depth which was the maximum length of our drill. Hit several layers of ice with water in between, but unable to reach all the way through. Drilled a second hole 7 meters away through 2 meter thick ice. Lowered a camera, but unable to see the ADCP on the monitor. The visibility in the water was poor due to large quantities of ice crystals in suspension. We will revisit the site later to see if the instruments could show up in a pressure ridge and be recovered. At this point, we have to accept the loss.
