1 The Blob, El Niño, and the Drought in Puget Sound Christopher Krembs, Marine Monitoring Unit, EAP, Ecology The Drought The Blob El Niño

2 Warmest first four months since 1981, (Source: NASA's Goddard Institute for Space)

3 The snow has melted early or came down as rain April 2010 March 2015 Feb 2013 Photo by Bill Baccus, Olympic National Park June 2015 Hurricane Ridge: winter snow is gone. Low snow has only occurred twice since 1960 (1977 & 2005).

4 Many rivers and streams are much below normal By June 1, 2015, most rivers and streams are at or below 10th percentile Most rivers and streams are at or below 10th percentile in greater Puget Sound Basin Several western regions are experiencing record low flows

5 The Fraser River has been running very high. The freshet is much earlier in 2015 Fraser River is the largest freshwater source of Salish Sea affecting estuarine circulation Higher than normal Lower than normal Expected

7 The Blob + El Niño invades Pacific, flummoxing climate experts Sea Surface Temperature (SST) anomaly, 29 January 2014 Sea Surface Anomalies Persistent mass of warm water affects: ocean currents, marine ecosystems inland weather One week mean sea surface temperature anomaly 8-14 March 2015.

8 The Blob in 2014, (NOAA)

9 The Blob hits Washington shores! Timing of coastal winds is important! Upwelling index (NOAA) YEAR JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC

10 Until September 2014 upwelled water keeps warm water offshore spring-neap cycle snowpack Coastal Upwelling Victoria Fraser San Juan Islands Seattle Skagit upwelled water low DO, high nutrients estuarine circulation tidal mixing over the sill Strait of Juan de Fuca Admiralty R. Puget Sound Upwelling Snow-fed rivers Rain-fed rivers Downwelling Estuarine circulation Tidal exchange

11 After September 2014 downwelling starts and brings in warm water spring-neap cycle snowpack Downwelling Victoria Fraser San Juan Islands Seattle Skagit downwelled warmer, lower nutrients, lower salinity, LOWER DO estuarine circulation tidal mixing over the sill Strait of Juan de Fuca Admiralty R. Puget Sound Upwelling Snow-fed rivers Rain-fed rivers Downwelling Estuarine circulation Tidal exchange

13 Eyes Over Puget Sound Marine Long-Term Monitoring Program Conditions were dominated by warm water associated with the NE Pacific Ocean warm surface anomaly. Starting in October, temperatures are the highest on our record since Oxygen and salinities are becoming lower. Higher Temperature! Lower Salinity Lower Oxygen Apr. 2015: Red boxes show that the water measured is warmer than any of our measurements since 1989.

16 Ferry monitoring observations Surface water (3m) in places already >15 C In spatial context: In temporal context: Pockets of sea surface temperatures are now reaching >15 C near Kingston. Temperature are favorable for harmful algae species to bloom. The Victoria Clipper IV carries sensors in its sea chest. The sensors allow us to get surface transects of temperature, chlorophyll, salinity, and other bio-optical measurements between Seattle and Victoria, BC twice per day.

17 What will the summer of 2015 bring?

18 The Blob is still offshore! (NOAA) 2014 May 2015 June 2015 Blob is ~500 km offshore

19 Will upwelled water in 2015 stay offshore? spring-neap cycle reduced snowpack Coastal Upwelling Victoria Fraser San Juan Islands Seattle Rivers estuarine circulation tidal mixing over the sill Upwelling Snow-fed rivers Rain-fed rivers Downwelling Estuarine circulation Tidal exchange

20 Will an El Niño deepen the nutrient rich water? spring-neap cycle reduced snowpack Coastal Upwelling Victoria Fraser San Juan Islands Seattle Rivers dense water too deep estuarine circulation tidal mixing over the sill Upwelling Snow-fed rivers Rain-fed rivers Downwelling Estuarine circulation Tidal exchange

21 Will summer squalls import more warm water? spring-neap cycle reduced snowpack Downwelling Victoria Fraser San Juan Islands Seattle Rivers estuarine circulation tidal mixing over the sill Upwelling Snow-fed rivers Rain-fed rivers Downwelling Estuarine circulation Tidal exchange

22 Speculating about the summer 2015 No matter in what direction the coastal wind will blow, we can expect a reduced renewal of water in Puget Sound. Puget Sound water will stay warm leading to potentially more regional water quality issues. Expect very different growth conditions for marine species.

23 The marine food web is responding (the news is coming in ) Energy-rich northern zooplankton species were replaced by southern copepods at end of Peter Chandler (Canada), San Diego meeting The Blob, May 2015) Much more gelatinous zooplankton, 'Crunchies' vs. 'Squishies, (John Dower, UVIC, CBC NES 6/8 here). A record high 96% diversion of returning Fraser River sockey salmon via northern Vancouver Island (LaPointe et al report, in prep). Largest toxic algae bloom stretching from Central California to British Columbia. NOAA (Seattle Times 6/16 here). First time PSP, DSP and domoic acid in Washington at the same time. DOH (Seattle Times 6/16 here).
