2017 Addendum — Ocean Acidification: From Knowledge to Action

The Washington Marine Resources Advisory Council has released an addendum to the 2012 report Ocean Acidification: From Knowledge to Action. The original report established a statewide strategy for addressing ocean acidification in Washington. The addendum identifies updates based on emerging science and management practices and is intended to be a companion to the 2012 report.

What is killing the coho?

Researchers are trying to determine which chemicals in stormwater are contributing to the deaths of large numbers of coho salmon in Puget Sound. It has prompted a larger question: What exactly is in stormwater, anyway?

Influence of human exposure on the anti-predator response of harbor seals (Phoca vitulina)

Seals and sea lions may be slowing salmon recovery, hurting orcas

Increased consumption of Chinook salmon by seals and sea lions in the Salish Sea “could be masking the success of coastwide salmon recovery efforts,” according to a new study published in the journal Scientific Reports. Endangered resident orcas are said to be declining in part due to a lack of available Chinook, the orcas' preferred prey.

Eyes Over Puget Sound: Surface Conditions Report, October 31, 2017

After a dry and sunny summer extending well into October, air temperatures are cooler than normal and precipitation has increased allowing rivers to regain strength. Despite a dry summer, Puget Sound is fresher this year than the past 17 years. As of September, warmer temperatures remained in South Sound. In October, surface water in the Straits however began to cool and the influence of rivers

With sea-level rise, waterfront owners confront their options

Climate change could cause sea levels to rise more than four feet in some parts of Puget Sound, leaving shoreline residents with some tough decisions. Experts say fighting the waves with conventional seawalls may not be the answer.
