To accomplish this goal, positional data was collected by 13 global positioning system (GPS) telemetry tags deployed over a 2-year period (2010–2011) on 11 individual Hawaiian monk seals, for a total of 38,232 hours (1,593 days). By using geo-spatial data bases, it was determined that four of the eight seals were exposed to a total of 14.48 hours (less than 1 day) of mid frequency sonar activity while the seal was within 36 km of a hull mounted sonar ship. Independently, the tag data were analyzed by HMSRP to identify specific dates where seal behaviors differed from “normal” for each individual. The time periods determined by HMSRP to be outside the “normal” range were compared to those time periods when a monk seal was in the vicinity of a hull mounted sonar ship while it was transmitting. The available data suggest there were no significant impacts from MFAS on the Hawaiian monk seals tagged in HRC during the 2010–2011 time period, as no outlier days occurred on the day of active transmissions....

Initially, the focus of this Project was on beaked whales. However, upon recovery of the gliders post-deployment, it was discovered that neither glider recorded any useable data above 2.5 kilohertz, well below the frequency of beaked whale vocalizations. It was then decided to analyze the available data for baleen whale and sperm whale (Physeter macrocephalus) vocalizations, which was originally a focus of secondary importance for the Project....
