The article mentions "... injury or death of thousands of whales each year". I trawled through a lot of the source articles referenced, and I can't find any sources for this data, except for an estimate from a Conservation Biologist based on extrapolation from regional studies.

I appreciate this can be hard to measure, and don't doubt there are some number of whale deaths caused by vessel collisions each year... Just feels a bit wild that a number of this magnitude is being used without much numerical evidence.

Cool product though - perhaps it could help with getting more accurate numbers
