It's a fair question but for me also it is too early to come to a conclusion. Too much movement and not enough data. Next analysis will be yearly paths with 50m temperature to see what that shows. It's likely to be warm pacific incoming from the Chukchi plateau as there is no rough topography at ~78N-140. Maybe the buoys will show us how 'wide' the warmer area is. Mercator at 34m and 92m depth misses the peak. Maybe Aslan can help with that.
OTG has plenty of suggestions
edit: latest data from itp121 is a bit cooler at 50m
