Tracking the winter range of the critically endangered western gray whale

October 2012

This case study outlines a successful western gray whale research and monitoring programme, co-sponsored by Exxon Neftegas Limited (ENL), a subsidiary of Exxon Mobil Corporation. As part of this effort, a satellite-tagging program was put into place in 2010 to better understand the winter range of the species after their summer and fall feeding period offshore Sakhalin Island, Russia. A tagged whale was followed by satellite for more than four months, giving scientists unique data and insight into the western gray whales’ winter journeys.
