Thompson, P.M., Brookes, K.L., Graham, I.M., Barton, T.R., Needham, K., Bradbury, G. and Merchant, N.D.

Assessments of the impact of offshore energy developments are constrained because it is not known whether fine-scale behavioural responses to noise lead to broader-scale displacement of...

Dyndo, M., Wisniewska, D.M., Rojano-Doñate, L. and Madsen, P.T.

Cetaceans rely critically on sound for navigation, foraging and communication and are therefore potentially affected by increasing noise levels from human activities at sea. Shipping is...

Spatial and Temporal Trends in the Distribution of Harbour Porpoises, White- Beaked Dolphins and Minke Whales Off Aberdeenshire (UK), North-Western North Sea.

2007
Pay-walled Journal Article

Journal of the Marine Biological Association of the United Kingdom

Weir, C.R., Stokin, K.A. and Pierce, G.J.

Most North Sea cetacean species are wide-ranging and consequently poorly studied. Spatial and temporal trends in the distribution of the harbour porpoise Phocoena phocoena, white-beaked dolphin...
