Eyes Over Puget Sound: Surface Conditions Report - March 26

Following a generally warmer and drier winter and then a cold spell in February, Puget Sound waters are cold for anchovies. The productive season is in full swing with algal blooms spotted in South Sound, Kitsap Peninsula, and Quartermaster Harbor. Jellyfish are abundant in some inlets, and Noctiluca stains the water orange in Hood Canal. We collect monthly data to keep you informed about the

Social networks a key to orca survival

Understanding the social networks and family bonds of Puget Sound's southern resident orcas may be critical to keeping the endangered whales from extinction. A healthy population is about more than numbers, scientists say. It's about connections.

Tracking the effectiveness of armor removal in Puget Sound

The removal of shoreline armoring has become a priority for the state's Puget Sound recovery efforts. The Puget Sound Ecosystem Monitoring Program (PSEMP) is providing details on the effectiveness of armor-removal projects at 49 study sites.

Risk of a major oil spill generates action in Olympia

Bills in the state legislature target oil spill threats to Puget Sound and its endangered killer whales.

Oil spill risks by the numbers

An EPA-funded study of oil spill risks in Puget Sound forms the basis of new legislation to regulate vessel traffic in the region. We break down some of the numbers from the study and look at where the risks may be greatest.

The survival of hatchery‐origin pinto abalone Haliotis kamtschatkana released into Washington waters

In Washington State, the pinto abalone (Haliotis kamtschatkana) has declined by 97 percent since 1992 and is unlikely to recover without intervention. A captive rearing and restocking pilot study shows promise for saving wild populations from local extinction.

Disease epidemic and a marine heat wave are associated with the continental-scale collapse of a pivotal predator (Pycnopodia helianthoides)

The sunflower sea star (Pycnopodia helianthoides) is highly susceptible to sea star wasting disease. The authors of a 2019 paper published in Science Advances document the rapid, widespread decline of sunflower stars and discuss the ecological implications of losing this important subtidal predator species.

The orca docs: Can medical interventions help?

This three-part series explores opportunities and challenges of using medical interventions to save Puget Sound's southern resident orcas from extinction. Part 1 looks at how scientists might treat endangered southern resident orcas that face starvation and risks of disease; Part 2 considers how veterinarians have intervened with other animals in the wild, and how this might apply to orcas in

Eyes Over Puget Sound: Surface Conditions Report - February 21, 2019

Although fall and winter were warm, February brought cold snowy weather and low river flows. Despite colder air temperatures, the productive season has already started in Hood Canal and Holmes Harbor. Puget Sound waters were warmer than expected through January, and the warmest waters were in Hood Canal, possibly creating a thermal refuge for cold-sensitive species such as anchovies. We saw lots
