Сахалин Энерджи
Multiple seismic surveys were conducted near Sakhalin in 2010, carried out separately by Rosneft, Sakhalin Energy and Gazprom. The surveys conducted by Sakhalin Energy and Rosneft apparently had corresponding monitoring and mitigation plans. The monitoring data, including acoustic and visual information on whale distribution and behavior, is yet to be analyzed. Two of those seismic surveys occurred later in the year when more gray whales were present and temporally overlapped. Critically endangered North Pacific right whales are also present in the region.
