Scientists tracking marine mammals in the Chukchi Sea report a record number of gray whales calves in July.
The federal Alaska Fisheries Science Center says, 57 cow and calf pairs were recorded.
The Eastern North Pacific population of gray whales is estimated between 18,000 and 21,000.
The animals make seasonal trips from the Chukchi Sea to Mexico. All the cow-calf pairs were all found within 30 nautical miles of the Alaska coast between Barrow and Point Lay.
