Evaluation of the potential for seismic surveys to impact lobster resources

Extensive seismic surveys used to understand the characteristics of the earth's crust (often to locate oil and gas wells) are being conducted in the waters around Newfoundland and Labrador, and have raised concerns of potential damage to fisheries resources. A previous study showed that the sound from an airgun used in seismic surveys caused changes in lobster tissues and potential organ damage one day after being exposed. However, there can be a delay in the expression of tissue damage after lobsters are exposed, and it is necessary to determine if more substantial effects appear after several days. This project will further examine lobsters exposed to airgun sound seismic surveys.
