Species of concern 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.

Eyes Over Puget Sound: Surface Conditions Report - February 26, 2013

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.

Indicator species

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

Report: Rockfish recovery in the Salish Sea

There are at least 28 species of rockfish in the Salish Sea, but their populations have declined in the past several decades. The proceedings from a 2011 rockfish recovery workshop in Seattle are now available.

Salish Sea tribes in Canada

This page includes links to information for First Nations living along the Salish Sea in Canada. First Nations peoples occupied what is now Canada prior to the arrival of Europeans and Americans, and over 50 cultural groups and unique languages are represented across the country.

The pattern of colder and fresher Puget Sound water persists. Jellyfish aggregations continue to persist in Budd Inlet. Debris lines are numerous and long. There are multiple oil sheens in Seattle waterways. CDOM (colored dissolved organic matter) sensor and en route ferry thermosalinograph provide an important tracer for freshwater entering Puget Sound from Whidbey Basin.

Carsey Institute studies on communities and coastal restoration in Puget Sound

In an effort to understand how residents of Puget Sound view social and environmental change in their region, researchers at the Carsey Institute at the University of New Hampshire and the National Oceanic and Atmospheric Administration collaborated on a public perceptions survey, visualization models, and stakeholder workshops in 2012. The results of their research are available online, and in

The weather has been warm, cloudy with weak winds from the south. Surface water temperatures range from 8.5-9.5°C. River flows are dropping below expected levels, yet the seasonal increase in freshwater can be clearly seen. Debris lines are numerous near river estuaries. Algal biomass is down but jellyfish aggregations continue to go strong in terminal inlets.
