A method was developed to quantify organochlorine pesticides in whale scat. This method would ideally replace analysis of pesticides in blood and tissue samples, which are difficult to acquire. Scat samples were collected from one stranded gray whale and three live whales. The samples were extracted with pressurized liquid extraction,...
This study was conducted to determine whether a low-powered sound source could be effective at deterring gray whales from areas that may prove harmful to them. With increased interest in the development of marine renewal energy along the Oregon coast the concern that such development may pose a collision or...
Gray whales accomplish an annual migration which
spans as much as 50° of latitude in the northeast
Pacific Ocean. This migration links their summer high
latitude feeding grounds with winter calving and breeding
areas. The purpose of this study was to determine how
adult females apportion their stored lipid reserves...
