Offshore wind raises questions for lobster harvesters about seabed disturbance, cable routes, and access to fishing grounds. Those questions deserve specific evidence. A possible mechanism, a behavioral observation, and a demonstrated decline in a lobster population are different levels of finding.
What cable research has found
BOEM’s 2024 review of electromagnetic fields summarizes a field experiment with American lobsters enclosed over an energized cable. Researchers observed some behavioral differences, but the cable did not appear to act as a barrier to movement. The study did not establish that offshore wind causes a decline in Maine’s lobster population.
The review also cautions that responses to experimental stimuli do not automatically describe behavior in a natural setting. Exposure level, species, life stage, cable design, and study conditions matter when interpreting a result.

Local effects and regional warming are separate questions
A claim about heat near a cable needs measurements of its magnitude, distance, duration, and biological consequences. It cannot simply be expanded into a claim that wind infrastructure is warming the Gulf of Maine or driving lobster migration across the region. Those broader claims require their own evidence.
What a useful project review should ask
- What habitat would construction and cable installation disturb?
- Where would fishing gear, navigation, or access be affected?
- What environmental measurements exist before construction?
- How will monitoring distinguish project effects from other changes?
- What would trigger mitigation if an effect is detected?
These are questions for evaluation, not a claim that every proposed project will produce the same outcome. A route-specific assessment and meaningful input from working fishermen are more useful than assuming that any one study settles every concern.
Keep conclusions proportional to the evidence
A behavioral response is worth studying, but it should not be relabeled as proven population damage. Likewise, a study that finds no barrier to movement does not establish that every project is free of effects. Look for the measured outcome, the study’s limits, and the monitoring proposed for the actual location.
