During the height of the COVID pandemic, human-generated ocean noise from freight shipping and recreational boating nearly stopped. Because some locales measure oceanic noise with hydrophones, open-source data offered lots of useful raw data. Artash Nath, a student researcher, analyzed some of this data to demonstrate how ocean noise impacts marine mammals and by what measure the noise was reduced when human activity stopped. He shares these findings on his website, Monitor My Ocean.  We spoke with Artash about these insights in episode 26 of Soundproofist.
