WindAction | Sonar Vessel Noise Survey: Technical Report
This important report analyzes underwater sonar noise levels captured by Rand Acoustics, LLC at different distances from an active sonar survey being conducted at a wind lease area 43 miles offshore New Jersey. Rand determined in his review of the data that the sound levels (in decibels) were much louder than those approved by NOAA. This report raises serious questions regarding whether the mitigations mandated by NOAA to protect marine mammals were sufficient since the mitigations were based on source sonar levels that were much quieter than those Rand measured. The executive summary of the R...
