ABSTRACT Time difference of arrival (TDOA) methods for acoustically localizing multiple marine mammals have been applied to recorded data from the Navy’s Pacific Missile Range Facility in order to localize and track humpback whales. Modifications to established methods were neces-sary in order to simultaneously track multiple animals on the range faster than real-time and in a fully automated way, while minimizing the number of incorrect localizations. The resulting algorithms were run with no human intervention at computational speeds faster than the data recording speed on over forty days of acoustic recordings from the range, spanning multiple years. Spatial localizations based on cor-relating sequences of units originating from within the range produce estimates having a standard deviation typically 10 m or less (due pri-marily to TDOA measurement errors), and a bias of 20 m or less (due primarily to sound speed mismatch). An automated method for as-sociating units to individual whales is presented, enabling automated humpback song analyses to be performed.(Tursiops truncatus, n = 6), false killer whales (Pseudorca crassidens, n = 3) and short-finned pilot whales (Globicephala macrorhynchus, n = 6). Satellite tags were deployed on five different occasions during this period, with four of the five efforts timed to coincide with SCCs (February 2011, August 2011, February 2012, February 2013). The remaining field effort occurred prior to the July 2012 Rim of the Pacific exercise. Initial analysis of tag and PMRF data revealed temporal and general spatial overlap for eight individuals of three species: bottlenose dolphin, short-finned pilot whale, and rough-toothed dolphin. This initial exposure analysis was restricted to one bottlenose dolphin, one short- finned pilot whale, and two rough-toothed dolphins. Based on photo-identification and association analyses, all tagged individuals are known to be from populations generally resident to the islands of Kaua‘i and Ni‘ihau. Satellite-tagged animals were exposed to estimated received levels of: 130 to 144 decibels for two rough-toothed dolphins, referenced to Standard Form 298 (Rev. 8-98) Prescribed by ANSI-Std Z39-18 SPAWAR Systems Center Pacific 53366 Front Street, San Diego, CA Scripps Institution of Oceanography 8635 Discovery Way La Jolla, CA
