When 100 seals were found in August (2018), researchers were concerned that there is something in the water that is causing the mass die off. The data shows that this is an above average mortality rate, which is normally 38 (10-year average). Unfortunately, researchers still don't know the cause.  Susan Shaw a marine mammal biologist that specializes in contamination hypothesizes that the die off is due to PCBs in the water.  More information is in the episode...take a listen.
