Monitoring

Monitoring encompasses the routine measurement of ecosystem indicators to assess the status and trends of ecosystem structure and function. Broadly, there are two goals for monitoring in the Puget Sound ecosystem. The first goal is to monitor status and trends of the ecosystem. This may take the form of snapshots of specific regions, or, more usefully, status monitoring tracks variability in carefully selected indicators over time. Status monitoring is fundamentally concerned with documenting spatial and temporal variability in ecosystem components and thus ideally relies on consistent long-term monitoring in a network of sites. A second aim of monitoring is to evaluate the effectiveness of management strategies. Effectiveness monitoring thus aims to detect changes in ecosystem status that are caused by specific management actions.

Overview

The Puget Sound Ecosystem Monitoring Program (PSEMP) is an independent program established by state and federal statute to monitor environmental conditions in Puget Sound.

Unusually warm water temperatures continue in central and south Puget Sound while Willapa Bay returns to expected water temperatures as a result of stronger coastal upwelling. Extensive mats of organic debris develop in many places, particularly in Central Sound overlapping with a fading Noctiluca bloom. King County confirms Noctiluca and shares plankton species information. Red-brown and brown blooms are going strong in southern inlets and around the San Juan Islands. Our inspiring WCC Intern gets on boats, into the air, and to the lab.

King County conducted physical and biological monitoring between 2010 and 2013 in the Lake Washington/Cedar/Sammamish (WRIA 8) watershed using common survey protocols and a probabilistic survey design. Hydrologic monitoring was also conducted at several locations to supplement physical and biological monitoring. 

With funding from an EPA grant from 2010-2014, King County worked with regional partners and experts to enhance data analysis tools and encourage collaboration and standardization for benthic macroinvertebrate monitoring in the Puget Sound region.

Record warm water temperatures and low oxygen continue in Ecology’s Puget Sound marine monitoring station network. Record low stream flows result in visibly low river discharge into Puget Sound, in particular for the Puyallup River. Abundant sun and unusually warm water temperatures fuel phytoplankton blooms in many areas. Bright orange Noctiluca blooms are surfacing in the Commencement Bay area and around Port Madison. Finger inlets of South Sound support extensive patches of jellyfish.

A 2015 paper in the Marine Ecology Press Series reports a trend toward more jellyfish and less of some forage fish species in Puget Sound. The paper analyzes more than 40 years of state data, and assesses potential human causes for the shift.

Warm waters from “The Blob” in Puget Sound combine with drought conditions as warm air has left little snow to feed the rivers. Water temperatures throughout Puget Sound are the highest in 25 years and oxygen is exhibiting record lows. High suspended sediment in the north is still coming in from the Fraser River. Otherwise, the surface waters appear very clear due to recent low river flows and weak blooming activity. A red bloom is present in Sinclair Inlet and in some confined bays. Patches of jellyfish, however, are going strong in inlets of South Sound and Sinclair Inlet. What does this all mean for salmon? Get to know some intertidal critters!
