NBK at Bangor EHW-1 Pile Replacement Project Final Marine Mammal Monitoring Report Construction Monitoring During construction monitoring, several vessel-based monitoring locations were used to monitor for marine mammals to ensure the animals’ safety outside the shutdown zone and to collect observational data regarding their behavioral responses to pile installation and removal activities (refer to the U.S. Navy’s Marine Mammal Monitoring Plan, Appendix A). Vessels were semistationary during construction monitoring. In the near-field (inside the WRA), vessels only moved occasionally to maintain adequate visual coverage or to collect acoustic recordings. Within the far-field (outside the WRA), the vessels moved more frequently. The vessel stationed at approximately mid-channel outside the WRA occasionally moved to the north and south to collect acoustic recordings relative to the extent of the 120 decibel (dB) root mean square (RMS) isopleth during vibratory pile driving. During acoustic recordings, the vessel remained stationary with the engines off to ensure the engine noise did not contaminate the recordings. This vessel also communicated with the nearshore observers regarding animals that were transiting the area or approaching the WRA. The general positions of vessel-based monitoring locations during the EHW-1 PRP are depicted in Figure 3. Construction monitoring was performed over a period from 4 October through 27 October 2011 (Table 2). The area monitored on any given day ranged from 1.4 to 7 square miles (mi 2 ; 3.6 to 18.1 square kilometers [km 2 ]), with an average of 3 mi 2 (7.7 km 2 ) (Table 2). Vessel tracks varied with construction activities and monitoring requirements, but were focused within and around the WRA near NBK at Bangor. Table 2.
