The goals of our project are (a) to improve our understanding of the interactions between the oceanographic conditions (e.g., ocean temperature) and the occurrence patterns of marine mammals in this area, and (b) to assess how global climate change may impact these interactions and patterns.
Ever since the 1960s, researchers have conducted oceanographic studies in Oregon waters along the Newport Hydrographic (NH) Line, which was established for the sake of continuity across studies. Despite a strong oceanographic understanding of the area, a significant gap in knowledge of cetacean distribution in Oregon waters has recently become apparent. We will join the legacy of other researchers who have collected samples, conducted visual and acoustic surveys, and developed an oceanographic record of this area. The NH Stations (indicated in pink triangles) depict the location where we deployed three Rockhopper units. These will record acoustic data here six months at a time.
