I am familiar with occupational noise exposure criteria and noise but had never heard of noise exposure criteria for marine mammals.

We know about the dangers of ocean noise for marine mammals and fishes, and have written several blog posts about this.

Now, a large group of scientific experts has revised criteria for marine mammal noise exposure first developed in 2003.

I am fascinated by how creative the researchers had to be to do hearing tests on harbor seals, for example, to be able to update the criteria based on better evidence.

We hope these criteria will be used worldwide as guides to develop quieter rivers and oceans, to protect no only marine mammals, but fishes and invertebrates, too.
