MAI Scientist to Kick-off Webinar Series on Underwater Acoustics for the International Regulatory Community


November 13, 2015
MAI’s Vice President of Environmental Programs, Dr. Kathleen Vigness-Raposa, will kick-off the first webinar in a five-part series on underwater sound, specifically designed to aid International regulators and other government decision-makers. As co-PI of the Discovery of Sound in the Sea project (www.dosits.org), Dr. Vigness-Raposa will present on sound movement/propagation and the different methods for measuring and reporting underwater sound levels. She will be followed by Dr. James H. Miller, University of Rhode Island, who will talk about ambient noise measurements and noise budgets.

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.

MAI Scientists Support Marine Mammal Studies In Southern California Bight

AUGUST 2013
MAI’s CEO, Clayton Spikes was responsible for providing the Fleet Test Plan and Concept of Operations documentation for each of the two Navy combatant ships (guided missile destroyer USS Dewey, and guided missile cruiser USS Cape St. George) involved in Behavioral Response Study (BRS)-13 (part of SOCAL-13). He also attended the Pre-sail and Post-test briefings for each ship. MAI Senior Scientist Mark Wilson, a retired Navy senior chief sonar technician, was the Unit Coordinator who rode each ship during their week-long BRS-13 project activities.

DOSITS 10-year anniversary

June 2013
The Discovery of Sound in the Sea website (DOSITS, www.dosits.org) is one of the most comprehensive Internet resources on underwater sound. The website provides peer-reviewed, scientific content on the physical science of underwater sound and how people and animals use sound. It also provides efficient access to timely information on the effects of underwater sound on marine animals.

To commemorate the 10th anniversary of DOSITS and thank the over 125 members of the acoustics community who have contributed their efforts, an evening symposium, sponsored by the Acoustical Society of America and Marine Acoustics, Inc., will highlight current advances in underwater acoustics on Tuesday, June 4, 2013, during the 2013 International Congress on Acoustics (ICA).
