The document summarizes conditions in Puget Sound related to warm water anomalies, drought, and impacts on marine ecosystems. It notes that 2014 and early 2015 saw the warmest temperatures since 1981 due to a warm water blob in the Pacific. This, combined with low snowpack due to drought, led to record low river flows into Puget Sound. The warm water entered Puget Sound in late 2014 and 2015, bringing higher temperatures and lower oxygen levels. Observations from aerial photos and ferries detected large jellyfish blooms and algal blooms, indicating the marine food web may be changing.

24. Speculating about the summer 2015
โข No matter in what direction the coastal wind will blow,we can expecta
reduced renewalof water in Puget Sound.
โข PugetSound water will stay warm leading to potentially more regional
water quality issues.
โข Will the situation becomebigger with El Niรฑo?
โข Expectvery differentgrowth conditionsfor marinespecies.
25. The marine food web is responding
(the news is coming inโฆ)
โข Energy-rich northern zooplankton species were replaced by southern
copepods at end of 2014. Peter Chandler (Canada),San Diego meeting

โข Much more gelatinous zooplankton, 'Crunchies' vs. 'Squishiesโ, (John
Dower,UVIC, CBC NES 6/8 here).
โข A record high 96% diversion of returning Fraser River sockey salmon via
northern Vancouver Island (LaPointe et al. 2015 report, in prep).
โข Largest toxic algae bloom stretching from Central California to British
Columbia. NOAA (Seattle Times 6/16 here).
