The North Atlantic right whale Eubalaena
Abstract: Collisions with vessels are a major cause of mortality for the severely endangered North Atlantic right whale Eubalaena glacialis, with the total population currently numbering only around 300 individuals. Although having a great impact upon the chances of survival of the species, right wh...

The rarity of interactions between whales and vessels requires several years to be simulated to produce sufficient collisions to draw conclusions about the effects of any changes to parameters.
