Offshore Distribution of Southern Resident Killer Whales in the Pacific Northwest
Project Objectives
1) Identify and classify Southern Resident killer whale (SRKW) detections from acoustic recorders and satellite tag tracking; 2) Develop a model to estimate the seasonal and annual occurrence patterns of southern resident killer whales relative to offshore Navy training ranges. 3) Characterize occurrence of anthropogenic sounds in potential SRKW habitat. 4) Develop state space habitat model for SRKW prey, based on fall Chinook salmon tagged released from California to British Columbia between 1977 and 1990 to estimate seasonal distribution along the west coast.

Analysis of scat samples from animals is a non‐invasive technique that can provide important data on animal diet, hormone levels, microbiome, and genetics. The use of a trained Conservation Canine (K9) to detect marine mammal scat at sea has been proven to be useful in the Pacific Northwest with Southern Resident Killer Whales (Lundin et al. 2016) and in other unpublished reports and media, but until now, had not been documented in Hawaii. In order to explore the viability of this method in Hawaii, the Navy invested in a pilot study, where the K9 was successfully trained to detect and ‘direct’ boat drivers – via changes in behavior – to the scat of three species of marine mammals (G. macrorynchus, K. breviceps, and P. crassidens).
