Mission Report (Michael Studinger, Mission Scientist)

Today's flight is primarily derived from the eastern portion of the 2012 PTSK High-Altitude flight, whose lines were themselves derived from 2009 LVIS lines over the main Pine Island Glacier trunk. The mission is designed to collect dh/dt measurements over this area. We supplement these lines with segments from the 2002-2009 NASA-Chilean and OIB lines over several of the tributary channels feeding the main channel.

Today was the first time on this deployment where Pine Island Glacier had conditions suitable for a science flight. We had a very short window between clouds clearing up and a new frontal system moving into the area. A satellite image 3 hours before we launched show significant high and low cloud cover in the area but the models predicted these clouds would dissolve by the time we get to the survey area. We have often made calls like this for PIG. It is a challenging are to get weather-wise. Given the bad weather in the area for the last 2 12 weeks (or longer) we were not alone in the survey area today. At 19:16 Zulu we saw a Twin Otter from the British Antarctic Survey descending 5 nautical miles to our right for a landing on the ice. 

In addition to our IceBridge survey lines we flew over 3 future drill sites of the British Antarctic Survey that will be occupied in December this year. We collected data over site PRES2 at 16:37:09 UTC, PRES3 at 16:37:24 and PRES1 at 17:22:27 UTC.

The conditions in the survey area were good. We were able to get under a layer of clouds near the calving front and only lost data at the beginning for 10 minutes due to dense low clouds.

We observed a 65 meter deep new crack at near the calving front of Pine Island Glacier.

LiDAR data collection started 10/29/2014 15:25 UTC and ended at 19:55 UTC. In total we collected 4.5 hours of LiDAR data.
