Eyes Over Puget Sound: Surface Conditions Report - September 17, 2018

Eyes Over Puget Sound: Surface Conditions Report - September 17, 2018

Air temperatures have remained high with precipitation and river flows below normal, extending the summer’s unusual conditions. Water temperatures were warmer in August, perhaps too warm for bull kelp and some salmon species in South Sound. In contrast, Hood Canal, North Sound, and the San Juan Islands provide optimal growth temperatures for herring and salmon. Many terminal inlets of Puget Sound

Pacific herring distribution in Puget Sound

Pacific herring are a pelagic fish species found from northern Baja California to northern Honshu Island, Japan. They are found throughout the Puget Sound basin and are a mix of “resident” and “migratory” stocks.

Climate change and ocean acidification may affect herring development

New research shows that warmer and more acidic oceans could lead to shorter embryos and higher respiration in Pacific herring.

Puget Sound Vital Signs

The Puget Sound Vital Signs are measures of ecosystem health that guide the assessment of progress toward Puget Sound recovery goals. They were adopted by the Puget Sound Partnership at the state of Washington to help guide local, state and federal ecosystem recovery efforts. Each of the six Puget Sound recovery goals are expressed with one or more Vital Signs. Vital Signs represent an important

Managing the Salish Sea’s ‘Herring 401 K’

Scientists argue that herring managers should take a tip from stock market investors and diversify the population’s “portfolio.”

Studies show challenges for eelgrass restoration

As critically important eelgrass declines in some parts of Puget Sound, scientists are trying to plant more of it. The health of the ecosystem may be riding on their efforts, but what they are finding is something that farmers have known for thousands of years: Getting something to grow may be harder than you think.

Policy pivot in Puget Sound: Lessons learned from marine protected areas and tribally-led estuarine restoration

A 2018 paper in the journal Ocean and Coastal Management examines and compares planning approaches used to develop marine protected areas and estuary restoration projects in Puget Sound. It finds that management policies can benefit from increasingly collaborative planning with a focus on multiple benefits such as flood control, salmon recovery, recreation and resilience to climate change.

Biennial Science Work Plan for 2016-2018

Biennial Science Work Plan for 2016-2018

This is the 4th biennial science work plan (BSWP) developed by the Puget Sound Partnership’s Science Panel. This 2016-18 BSWP, like its predecessors, identifies specific science work actions to be done over the next 2 years and provides recommendations for improvements to the ongoing science work in Puget Sound. This version of the BSWP builds upon the Partnership’s Strategic Science Plan (2010)

Nights in the lives of the rhinoceros auklets of Protection Island

More than 70 percent of the seabird population of Puget Sound nests on a single island in the Strait of Juan de Fuca. That includes a massive colony of rhinoceros auklets that has drawn the interest of scientists and birders alike. Our writer Eric Wagner visited the island this summer and reports on a long-term study of the auklets that is revealing new information about the health of seabirds in
