Data from: Harbour porpoise responses to pile-driving diminish over time ...
Estimating impacts of offshore windfarm construction on marine mammals requires data on displacement in relation to different noise levels and sources. Using echolocation detectors and noise recorders, we investigated harbour porpoise behavioural responses to piling noise during the 10-month foundat...

Estimating impacts of offshore windfarm construction on marine mammals requires data on displacement in relation to different noise levels and sources.
