Active Faults and Paleoseismology in Northeastern Sakhalin, Russia

Distribution and abundance of western gray whales off northeastern Sakhalin Island, Russia, 2001’003

In 2001-2003, >60,000 km of aerial surveys and 7,700 km of vessel surveys were conducted during June to November when critically endangered Korean-Okhotsk or western gray whales (Eschrichtius robustus) were present off the northeast coast of Sakhalin Island, Russia. Results of surveys in all years indicated gray whales occurred in predominantly two areas, (1) adjacent to Piltun Bay, and (2) off...

Status of western gray whales off northeastern Sakhalin Island, Russia, in 2008

A collaborative Russia-U.S. research program on western gray whales (Eschrichtius robustus) summering off northeastern Sakhalin Island, Russia, has been ongoing since 1995 and has produced important information on the present day conservation status of this critically endangered population. This paper reviews findings from 2008 research activities and combines such with data from previous years...

Seasonal and annual variation in body condition of western gray whales off northeastern Sakhalin Island, Russia

The western gray whale population (Eschrichtius robustus) is critically endangered and its potential for recovery is uncertain. Along with other natural and anthropogenic threats, western gray whales are susceptible to nutritional stress, known from regular observations of individual whales in compromised body condition. Thus, the ability to visually quantify the relative body condition of free...
