Sea ice contours: 15% (blue), 50% (black), 90% (red)
2-m temperature contour: -1.8 °C
U/V transect contour: 0 m/s
Update [17:00PM, Sat., Aug 21, 2021 PST]:
- A low pressure system west of 150 °W. Will encounter low surface visibility and ceiling height at 76 °N.
- The surface temperature is slightly above -1.8 °C. Might need to be careful about slush when dropping AXCTDs.
- A narrow belt of thick ice near the ice ice, but the ice to the north is thinner. The sea ice concentration shows a similar signature. It is interesting to see how this low pressure system and another one that will develop to the west will affect this large area of thin ice.
