How many walruses are in Alaska's Chukchi Sea?

In 2007, walruses began coming onshore in large numbers on the Alaska coast of the Chukchi Sea, which allowed for more accurate population counts through the use of small aerial drones, satellite tags, and calculations based on walrus behavior. The number of walruses using the U.S. side of the Chukchi Sea in autumn was estimated to be 166,000 in 2018 and 189,000 in 2019. These numbers are significantly more precise than earlier population estimates and the data collection methods are less likely to disturb the walruses than the previously used airplanes.
