Eyes Over Puget Sound: Surface Conditions Report - February 3, 2021

Rivers are flowing higher than normal since 2020. Winter weather has been warmer and wetter. In marine waters, temperatures have become too cool for Northern Pacific anchovies to tolerate in North Sound. From patches of jellyfish and snow geese, to sediment and early blooms, there is more happening in the winter than you might expect. Puget Sound has many species worth showcasing such as the heart

Priority science to support Puget Sound recovery: A Science work plan for 2020-2024

Priority Science to Support Recovery of the Puget Sound Ecosystem: A Science Work Plan for 2020-2024 (SWP for 2020-2024) describes the information, learning, and interaction needed to support the coordinated efforts to recover, protect, and improve the resilience of the Puget Sound ecosystem.

Sensing liminal landscapes in Puget Sound

Puget Sound's shorelines are "liminal landscapes" that can inspire senses of "escape, transformation, and human creativity," according to a 2021 paper in GeoJournal. That may have regional policy implications as coastal researchers increasingly recognize the need to incorporate community inclusion and 'sense of place' in management decisions. The paper includes findings from a 12-county survey

Antibiotic resistance of bacteria in two marine mammal species, harbor seals and harbor porpoises, living in an urban marine ecosystem, the Salish Sea, Washington State, USA

Harbor seals and harbor porpoises in the Salish Sea are showing a relatively high presence of antibiotic-resistant bacteria. A 2021 paper in the journal Oceans suggests that these findings may indicate a wider problem among other species in the region.

Puget Sound National Estuary Program: Tribal implementation final report

This report details the outcomes, successes, and reflections of the final two years (2014-15) of an Environmental Protection Agency (EPA) National Estuary Program award dedicated to tribal restoration and protection projects in the Puget Sound watershed.

Once hearty 'hooligans' declining in the Salish Sea

A river spawning species of forage fish known as the longfin smelt is rare and getting rarer in the Salish Sea. Biologists are looking into the mysterious decline of the ‘hooligans’ of the Nooksack.

Types of estuaries in Puget Sound

An estuary is a place where saltwater from the ocean mixes with freshwater from rivers and streams. Technically, this defines all of Puget Sound, but scientists have identified several types of "sub-estuaries" within the water body. These include pocket estuaries (or embayments), tidally-influenced rivers and wetlands and other areas near the shoreline connected with freshwater sources. This

Pathology findings and correlation with body condition index in stranded killer whales (Orcinus orca) in the northeastern Pacific and Hawaii from 2004 to 2013

A 2020 study of pathology reports for 53 stranded killer whales in the northeastern Pacific and Hawaii showed that deaths related to human interaction were found in every age class. Vessel strikes accounted for the deaths of four of the nine endangered southern resident killer whales identified in the study. The findings were published Dec. 2 in the journal PLOS ONE.

Timeline: The search to find a chemical that kills coho salmon in urban streams

The search for why large numbers of spawning coho salmon have been dying in Puget Sound's urban streams goes as far back as the 1980s and culminated this year with the discovery of a previously unidentified chemical related to automobile tires. We offer a detailed timeline for the discovery.
