Dear Marmam, We have recently published the following paper in the Proceedings of Royal Society B (Biological Sciences): Tracking leatherback turtles from the world's largest rookery: assessing threats across the South Atlantic Witt MJ, Bunguno EA, Broderick AC, Coyne MS, Formia A, Gibudi A, Mounguengui GAM, Moussounda C, Nsafou M, Nougessono S, Parnell RJ, Sounguet G-P, Verhage S and Godley BJ http://rspb.royalsocietypublishing.org/content/early/2011/01/05/rspb.2010.24... The satellite-tracked movements of the turtles included in the publication are available on www.seaturtle.org While the species concerned is not a marine mammal, the method of quantifying threat might be of interest to those undertaking marine mammal movement studies.
