MAI Scientists Measure Construction Noise from First Offshore U.S. Wind Farm

September 2015
MAI’s Vice President of Environmental Programs, Dr. Kathleen Vigness-Raposa, and Staff Scientist, Jennifer L. Giard, are part of the team of researchers measuring the underwater sound created by the pile-driving phase of construction of the first offshore wind farm in the United States. By towing a horizontal array of hydrophones along a transect away from the pile-driving activity, they hope to address the question of where the sound transitions from high intensity, short duration signals to low intensity, long duration signals, which has implications for its potential impact on marine life.
