Expedition Echo is a 7 day research expedition that continues the work of Expedition Underway, our first in a series of Belize expeditions, that launched in 2016. During Expedition Echo, four scientists, a filmmaker, an artist, and a wildlife musician will search for the whales and dolphins that inhabit the coastal and offshore waters of Belize. This expedition will continue the first systematic and comprehensive study of marine mammal population distribution and behavior. Our researchers will employ methods including photo identification, hydrophone audio recordings, aerial drone video, and toxicology/ genetic testing. The information collected on this expedition will be used to facilitate improved conservation management as well as further collaboration with NGO’s and government officials to improve long-term monitoring efforts and marine mammal protection.
