Age- and sex-specific mortality and population structure in sea otters
James L. Bodkin, A.M. Burdin, D.A. Ryazanov
2000, Marine Mammal Science (16) 201-219

We also examined 363 carcasses recovered after the 1989 grounding of the T/V Exxon Valdez, to characterize age and sex composition in the living western Prince William Sound (WPWS)...
