NMFS Issues IHA for L-DEO Atlantic Seismic
The U.S. National Marine Fisheries Service has issued a Marine Mammal Protection Act Incidental Harassment Authorization to Lamont-Doherty Earth Observatory, in collaboration with the National Science Foundation, to take marine mammals, by harassment, incidental to conducting a marine geophysical survey on the Mid-Atlantic Ridge in the north Atlantic Ocean in international waters, from April 2013 through June 2013. This IHA is effective April 8, 2013, through June 24, 2013.

The Marine Mammal Commission file comments criticizing several aspects of NMFS' proposed IHA. NMFS' response to these comments generally defended the proposed IHA. For example, NMFS responded that the sound propagation zones were appropriate: “Because the modeling matches the observed measurement data, the authors concluded that those using the models to predict zones can continue to do so, including predicting exclusion zones around the vessel for various tow depths.”
