COMPTUEX/JTFEX EA/OEA Final Chapter 44.3.1.7.22 Estimated Acoustic Effects on Pinniped-Phocids not listed under ESANorthern Elephant Seal (Mirounga angustirostris)The northern elephant seal is not listed under the ESA, and the California Breeding Stock is notconsidered depleted or strategic under the MMPA. The California Breeding Stock has recovered fromnear extinction in the early 1900s to an estimated 60,547 (Carretta et al., 2005). The modeling efforts andharassment analysis for mid-frequency active sonar estimates that no Level A or Level B harassmentwould occur (Table 4.3-30). No northern elephant seals will be exposed to impulsive noises or pressuresfrom underwater detonations that would cause TTS or any impulsive noise that could cause physicalinjury.Table 4.3-30.
