NOAA survey shows shocking lack of thermal barrier between northern and southern Bering Sea

Diomede, Alaska, United States |
The “thermal curtain” is another expression for “cold pool” that acts as a barrier to keep some species—pollock and Pacific cod, for example — from migrating across the eastern Bering Sea shelf and northward toward the Bering Strait. For the first time in 37 years of surveying the Bering Sea, we could not find the cold water barrier.
