Cassidy Beach spent her 2023 Hollings summer internship at the Northeast Fisheries Science Center using passive acoustic monitoring to explore dolphin and harbor porpoise habitat use at Stellwagen Bank National Marine Sanctuary (SBNMS). By detecting and analyzing the sounds of dolphin and harbor porpoises, work like Cassidy’s can help fill the gaps in knowledge about habitat use of these species in SBNMS.
