Marie-Ana Mikus
Cetacean Conservation Research Program Technician

Marie-Ana is a research technician for the Raincoast Cetacean Conservation Research program. She holds a MSc Degree in Animal behavior from the University of Rennes (France) where she studied small-clawed otter acoustic communication. She has extensive experience in behavioral and acoustic field data collection and acoustic analysis of animal sounds, particularly cetaceans. Since 2016, she has assisted with the collection and acoustic analysis of field recordings of beluga whales from Cunningham Inlet (Canadian High Arctic), the Churchill River Estuary and the St. Lawrence River Estuary, and has been involved on studies of killer whale acoustics and underwater noise impacts on cetaceans.

As a field technician, Marie-Ana is experienced with the deployment and troubleshooting of digital hydrophones, a competent small-boat handler, and a certified drone pilot.
