Today the WHOI team is putting in their first of 5 Ice Tethered Profilers (ITP) of this cruise. (For a detailed description of an ITP, visit the WHOI ITP website.) The first thing to do is find some ice.
Rick and Will are flying out to look for a suitable ice floe. The LSSL Ice Observer Marie-Claude Bouchard accompanies them and adds her expertise. The ideal piece of ice is at least 3 meters thick, has a flat top indicating even growth of the ice over time, and few, if any, melt ponds. When they spot one, pilot Chris Swannell will land so Rick and Will can drill a test hole. Once the ice is determined to be suitable, the spot is marked with a flag and GPS.
The drill test hit water about half way down indicating that the floe was not solid or stable enough to support an ITP. After surveying more of the area by air, another one could not be found. They will try again tomorrow, as we move even further north.
Back at the ship, the sun came out and so did a few of the scientists -- for a bit of Vitamin D therapy.
