We reached HU48 at 12:20pm. The total station depth was 110.0 meters and the surface temperature was 1.44C.

At 3:04pm, we arrived at HU45M. The surface tempertaure was 1.47C and the total depth was 96.4 meters.

The final 2 stations of the evening were HU37, which had a total depth of 73.6 meters and a surface temperature of 1.08C, and HU38, which had a total depth of 135 meters and a surface temperature of 1.9C.

We've been told that the weather is going to pick up later tonight and we may have to head to shore. I'll update you as I learn more.
