Federal researchers in the Bering Sea have released recordings of songs by some of the rarest whales in the world. While this is exciting news for marine science, it could point to heartache for North Pacific right whales.

The National Oceanic and Atmospheric Administration is considering designating some 35,000 square miles of ocean in the Bering, Chukchi and Beaufort seas as special habitat for ringed seals, which are the main prey of polar bears. The seals were declared threatened in 2012 due to the loss of sea ice from climate warming. Ringed seals use sea ice for breeding and molting.
