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.

Lower than expected air temperatures and sunshine are now both increasing; rivers are generally running high. Willapa Bay unfolds its beauty from a bird’s-eye view. The spring phytoplankton bloom is picking up in Puget Sound. A large red-orange-brown bloom persists in southern Hood Canal at a scale sufficient for the MODIS satellite to pick up. Jellyfish are still going strong in southern inlets. Ocean climate indices (PDO, NPGO and Upwelling Index) explain much of the variability in Puget Sound temperature, salt and oxygen. Nutrients, however, are steadily increasing while sub-surface algal pigments (chlorophyll a) are declining!

Canadian and U.S. governments differ on special status for bocaccio in the Salish Sea. 

The Encyclopedia of Puget Sound species library now includes a list of species of concern in the Salish Sea watershed. The list was created by Joe Gaydos and Jacqlynn Zier of the SeaDoc Society, and was released as a paper presented as part of the Proceedings of the 2016 Salish Sea Ecosystem Conference in Vancouver, BC.

The weather has been relatively cloudy, warm and dry. We found less debris in the water but saw several large tidal eddies and suspended sediment plumes. Jellyfish continue to go strong this winter. We also observed early algae blooms in Hood Canal and Eld Inlet as well as multiple oil sheens in Seattle waterways. Listen to our marine flight technician discuss EOPS on the radio.

An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem. For example, plants or lichens sensitive to heavy metals or acids in precipitation may be indicators of air pollution. Indicator species can also reflect a unique set of environmental qualities or characteristics found in a specific place, such as a unique microclimate. However, care must be exercised in using indicator species. Judging an ecosystem based
