Dear Colleagues, On behalf of the authors and co-authors, we are pleased to announce the publication of a special issue on western gray whales and seismic operations in the journal of Environmental Monitoring and Assessment. The issue is dedicated to Rodger Melton who was instrumental towards establishing a long-term western gray whale research program off Sakhalin Island, Russia as well as mitigation and monitoring measures to minimize the impacts from oil and gas operations in the area. The issue summarizes the mitigation and monitoring approaches taken and assesses the impacts of seismic surveys that occurred near the gray whales feeding grounds off Sakhalin. The issue is open access and available online at https://link.springer.com/journal/10661/volumes-and-issues/194-1/supplement. Below are the individual papers. Streever, B.
