Bahamas' Dolphins: Post-Hurricane Dorian Update

The Bahamas Marine Mammal Research Organisation (BMMRO) is using Loggerhead Instruments' recorders to document changes in dolphin detections and ambient noise as Abaco recovers from Hurricane Dorian, which devastated the Bahamas in September 2019. Scientists at BMMRO recover and redeploy recorders approximately every two months, as Covid restrictions allow.

An initial analysis of the first six months of post-hurricane data has been completed by a Masters' student from the University of St. Andrews and shows an expected increase in dolphin detections as the ambient noise has decreased. These changes are due to a 90 percent reduction of boats in the area, a lingering effect of the hurricane.

Bahamas’ researchers use a variety of Loggerhead acoustic recording devices. Something old, something new, something donated, something blue.
