March 8, 2019 — For the second straight year, the Bering Sea — a turbulent and bountiful stretch of the northern Pacific Ocean — is virtually ice free at a time of year when it should be gaining ice.
Why it matters: The ice pack’s ebb and flow each year has far-reaching consequences for the broader Bering Sea ecosystem, including determining the reach and abundance of prized fish species such as Alaska pollock and Pacific cod. This is the richest fishing ground in the U.S., featured in the Discovery Channel’s “Deadliest Catch.”
The big picture: Scientists who keep close tabs on this region say the ice’s early melt is upending life in the Last Frontier. It also portends consequences for the Lower 48 states and beyond. In a new study published in Earth’s Future on Thursday, scientists warn that Arctic climate change is already reverberating far outside the region.
- By the end of February, Bering Sea ice extent was lower than it has been since written records began in 1850.
- The March 6 departure from the long-term average shows that an area of ice equivalent to California and Montana combined is missing from the Bering Sea.
