Description The Washington State Department of Ecology has been routinely monitoring marine water quality throughout the Puget Sound since 1973. A historic baseline, established from 1999 to 2008, allows us to examine how water quality varies year to year as a result of both natural and human influences. The recent large-scale climate anomaly, “the Blob,” impacted this region when a mass of warm water entered Puget Sound in the fall 2014. In conjunction with higher-than-normal air temperatures, patterns of estuarine circulation and stratification were regionally altered in Puget Sound. Changes to these physical patterns affect ecosystem function, starting at the base of the food web with phytoplankton. The water quality data collected monthly in 2015 allows us to gain a better understanding of how large-scale climate anomalies affect the timing and span of phytoplankton blooms in Central and South Puget Sound. Understanding which regions in Puget Sound were the most adversely affected by the Blob provides insight into which regions are the most vulnerable to future large-scale climate impacts.

This poster was presented at the Salish Sea Ecosystem Conference, April 4–6, 2018 in Seattle, WA.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
