Mission Report (Michael Studinger, Mission Scientist)

Today the weather was suitable for the first sea ice mission. The Ross Sea Fluxgate mission plan (see below) has been given the highest priority by the IceBridge Sea Ice Science Team. At this time of the year the northern Ross Sea has many leads with open water, something that tremendously helps calculating sea ice thickness from ice freeboard measurements. From an operational point this is bad news since the many leads are a source of moisture that causes widespread fog and low cloud cover, making it a challenge to collect data with optical instruments that require and unobstructed view of the ice surface. Today’s mission was another uneventful flight. As expected we were in and out of clouds requiring the usual frequent elevation changes to avoid cloud and fog. We fly in conditions much worse over the Arctic Ocean compared to what we have encountered today.

The goal of today’s flight was to estimate sea ice thickness across a 1,400 km long fluxgate in the northern Ross Sea, were the sea ice is streaming northward from McMurdo Sound into the Ross Sea. The northern most profile runs from Cape Adare on the west to Sulzberger Bay on the east. A second east-west line parallel to the first, captures the ice condition south of the flux gate. This IceBridge mission is intended to complement a ship-based mission anticipated for the austral spring 2015, which will focus on a detailed survey of the sea ice and snow conditions in this same area.

In order to get back onto our normal schedule we had to shorten the 8 hour mission plan to a 7 hour flight. Instead of flying low on the transit line we collected data from high altitudes saving time. We had to break off the southern fluxgate line 400 km off the cost in order to land in McMurdo at 17:00 local time. We started the flight collecting more calibration data for the CReSIS MCoRDS system at 10,000, 15,000, and 18,000 ft MSL. On the way home we collected calibration data over sea ice for the CReSIS accumulation radar at 3000, 4500 and 6000 ft MSL.

Data collection started 11/20/20/2013 20:53 UTC and ended at 11/21/2013 03:54 UTC. In total we collected 7.0 hours of science data.
