Description The Salish Sea displays strong seasonality in water temperature which can impose physiological limits on temperature-sensitive species. The exchange of Puget Sound with coastal water dictates isothermal patterns that are relevant to temperature-sensitive species. Using a ferry vessel is one mode of measuring near-surface water temperature. With equipment on the Victoria Clipper IV ferry, we collected geo-referenced and high-frequency water temperature measurements between Seattle, WA and Victoria, B.C. The data can be used to identify when conditions are potentially favorable for temperature-sensitive species such as Northern anchovy (Engraulis mordax). In the Salish Sea, Northern anchovies have a temperature threshold of 8-9 °C. We examine isothermal patterns to describe when Northern anchovies may survive winter conditions in the Salish Sea.

This poster was presented at the Salish Sea Ecosystem Conference, April 4–6, 2018, Seattle, WA.
