Dear Colleagues, I am an MSc candidate working with Dr. Trites in the Marine Mammal Research Unit at UBC, Vancouver, BC, Canada. As part of my thesis research, I am building a bioenergetics model to estimate the prey requirements of Pacific white-sided dolphins (*Lagenorhynchus obliquidens*) on the BC coast. I am writing to request your help in locating data or references to publications that recorded the proportion of blubber, lean tissue or water in the body of the Pacific white-sided dolphin. I am also interested in obtaining these measurements for other dolphins in the *Lagenorhynchus*genus (Atlantic white-sided, Dusky, Peales, White-beaked, Hourglass). Your assistance with this would be greatly appreciated, Thanks very much, Erin -- Erin Rechsteiner MSc Candidate, Zoology Marine Mammal Research Unit, UBC Room 247, AERL, 2202 Main Mall Vancouver, B.C.
