NMFS Issues Seismic IHA for South-Eastern Pacific Ocean
On May 9, 2012, the U.S. National Marine Fisheries Service published Federal Register notice that NMFS has issued an Incidental Harassment Authorization to the Scripps Institution of Oceanography to take marine mammals, by Level B harassment, incidental to conducting a low-energy marine geophysical survey in the south-eastern Pacific Ocean, May, 2012. This IHA is issued under the Marine Mammals Protection Act. This IHA is noteworthy in that, when estimating some Takes, NMFS used

    "habitat modeling as a method to estimate cetacean densities on a finer spatial scale than traditional line transect analyses by using a continuous function of habitat variables, e.g., sea surface temperature, depth, distance from shore, and prey density…."
