REMARKS: Arrived at the ice edge around 1600 on 4/30 and began trawling with the Tucker in 3-10/10 ice cover. Did two long tows and then had another rendezvous with the Nathaniel B. Palmer, also in the area working the GLOBEC survey grid. The captains maneuvered closely and we used the personnel basket for transfers in an area of 10/10 ice coverage. We exchanged some needed electronics spares, lab chemicals, and had a brief visit with our comrades. Following our rendezvous we continued trawling through midnight and then conducted another long ADCP/CTD survey until 0900 today (5/1), working in and out of the sea ice. After our survey was complete our whale biologist, Ari Friedlander, went out in the Zodiac and successfully sampled eight more humpbacks over three hours as a large pod moved through the area. Jose Torres' divers were in the water by 1400 and back on board by 1630. We are currently trawling, doing three long tows with the Tucker after the divers got back aboard, followed by the ten meter MOCNESS. We are still working in the vicinity of the ice edge, starting in the ice and towing through the margin out to open water.
