The scope of this research encompasses developing a better understanding of how exposure to different water temperatures affects the survival of adult Chinook Salmon migrating to spawning grounds in the Central Valley of California. How thermal exposure affects the probability of mortality for salmon migrating to spawning grounds, the location and timing of exposure risk, and how additional environmental conditions influence the susceptibility of salmon being negatively impacted by thermal stress are important unanswered questions that will benefit fisheries management.

We intend to acoustic tag subadult and adult fall-run Chinook salmon in the ocean in 2022 and 2023 with temperature emitting acoustic tags and track both their upstream migration success, and thermal exposure profile.
