Megan will be studying the factors influencing vocal repertoire variation of a small population of Guiana dolphins in Costa Rica.

Ian Portuguez, Licenciatura, Universidad Nacional de Costa Rica

Ian is using autonomous recorders to study the acoustic presence of Central American humpback whales, and documenting their soundscape. His study is taking place in the Papagayo Gulf and Cuajiniquil Bay in Costa Rica.

Ilaria Coero Borga, Ph.D. student, University of Vermont

Picture
Ilaria will be using machine learning computational tools and AUV to study humpback whale female-calf behavior and communication in Central America.

Franny Oppenheimer, AMP student, University of Vermont

Picture
​Franny is using machine learning approaches to study humpback whale songs in the Chiriqui Gulf in Panama. This is an important breeding ground for humpback whales from the breeding stock G, that migrate from Chile and the Antarctica Peninsula. This is a collaborative work with Kristin Rasmussen, Panacetacea.

Cesar Castro, Licenciatura, Universidad de Costa Rica

Picture
Cesar is studying the whistle repertoire of coastal pantropical spotted dolphins, focusing on the influence of context and group size on vocal repertoire diversity. HIs study is taking place in the local population of the Santa Elena Bay in Costa Rica.
