Western Pacific Gray Whale, Sakhalin Island 2010
These maps depict the movement of a satellite-monitored 13-year old male western gray whale, which was tagged on 4 October off Sakhalin Island, Russia, migrating from the Sea of Okhotsk.
In the 98 days since application, the transmitter has sent 1374 messages and the whale has traveled 4432 km. The OSU MMI speed filter results in fewer locations being shown on the map than are received from the satellites. Thus, only the 220 locations that have passed the filter are shown, from the 350 locations calculated to date.
"Flex" departed the Kamchatka coast on 3 January. In the last week, he has crossed more than half of the Bering Sea, arriving at the slope edge of the eastern Bering Sea shelf on 9 January, and covering 1210 km (since turning from the Russian coast) in 164 hours for an average of 7.378 km/hr on a general heading of 65°.
Use of these figures requires the inclusion of the following recognitions:
This research was conducted by A.N. Severtsov Institute of Ecology and Evolution of the Russian Academy of Sciences (IEE RAS) and Oregon State University Marine Mammal Institute; in collaboration with the University of Washington, Sakhalin Research Institute of Fisheries and Oceanography, and Kronotsky State Nature Biosphere Reserve. The research was contracted through the International Whaling Commission (IWC) and International Union for the Conservation of Nature (IUCN) with funding from Exxon Neftegas Ltd. and Sakhalin Energy Investment Company Ltd.
Current (10 days) progress:
A highly endangered whale typically seen near Russia's shore is taking a swim across the Bering Sea toward Alaska.
