Combining SRKW Tagging Acoustic Sighting Data

About

In this analysis, we integrate limited acoustic detections over a 7-year period with two other data sources: opportunistic visual sightings, and output from a state-space movement model fit to the locations from a single satellite-tagged individual. We illustrate a case study with an application to endangered Southern Resident killer whales, where the focus is understanding the coastal habitat use of this population in winter and spring months. Predictions from our state-space movement model suggest in winter of 2014, SRKWs spent the highest density of time located off the Columbia River and near Westport. Other areas with concentrated effort included off the Olympic Peninsula in Washington State, and near the Mad and Eel rivers in Northern California.
