The East Coast Marine Mammal Acoustic Study

ECOMMAS is a long-term, on-going study into how underwater noise generated by offshore industry impacts the distribution of dolphins and porpoises in the Scottish North Sea. Acoustic recorders (C-PODs and SM2Ms) are deployed at 30 sites across 10 locations along the east coast. They record underwater noise and count echolocation clicks to measure dolphin and porpoise presence and absence. They are deployed in the spring and are recovered after ~ 4 months. In 2015 and 2016, a second deployment was issued in July/August.
