The effects of vessel slowdowns on foraging habitat of the southern resident killer whales

Open Access Peer Reviewed Research Article 2020

Proceedings of Meetings on Acoustics

Trounce, K. Robinson, O., MacGillivray, A., Hannay, D., Wood, J., Tollit, D. and Joy, R.
Analysis of participation in ECHO program, a collaborative programme to introduce voluntary slowdowns for commercial shipping traffic. A 61% participation rate resulted in 22% reduction in ‘lost foraging time’. Increased leniency in target speeds resulted in increased participation to 87% and a reduction of lost foraging time on the order of 15%. Results suggest effectiveness as potential mitigation measure.
