Description The poster, Recent climate patterns are affecting seasonal water residence times and water temperatures in Puget Sound, is available at https://fortress.wa.gov/ecy/publications/SummaryPages/1803023.html.

In this analysis, we contrasted temperature records from Ecology’s long-term dataset using 2014-2017 to infer residence time and changes in water masses during the extreme climate years. At the end of 2014, water temperatures in Puget Sound rapidly increased in response to The Blob and persisted into 2017. Climate anomalies over land caused premature snow melt and freshening of Puget Sound. The seasonal shift in freshwater delivery increased winter estuarine circulation, which allowed greater import of heat from the ocean, but decreased summer circulation, which retained more heat in Puget Sound in summer. In both seasons, Puget Sound temperatures increased, affecting water quality and ecosystem performance. Increased winter temperatures >8 °C might have promoted overwintering for temperature-sensitive species such as Northern anchovy.

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