A review of Puget Sound marine and nearshore grant program results, Part 2
A July 2016 report from the University of Washington Puget Sound Institute summarizes and reviews 10 EPA-funded projects focusing on Puget Sound's marine and nearshore environments. The projects were conducted between 2011-2015 with support from the EPA's National Estuary Program. The report is an analysis of findings on invasive species, toxics, oil spill, and integrated risk assessment.
Harmful algal blooms in the Salish Sea
Formerly known as “Red Tide”, harmful algal blooms are a health concern for both wildlife and humans. The following is a brief review of some of these algae and their effects.
Eyes Over Puget Sound: Surface Conditions Report – July 20, 2016
Through June, air temperatures and sunlight were higher than normal. Recent rain generally improved river flows. However, the Fraser river flow remains extremely low, reducing water exchange with the ocean. Water temperatures are still breaking records, yet dissolved oxygen levels are normal. Coastal bays are influenced by upwelling and exhibit lower oxygen and higher salinities. Puget Sound algae
Killer whale miscarriages linked to low food supply
New techniques for studying orcas have been credited with breakthroughs in reproductive and developmental research. Drones and hormone-sniffing dogs are helping scientists connect declines in food supply with low birth rates and poor health. Update: The research described in this 2016 article has now been published in the 6/29/17 issue of the journal PLOS ONE.
Salish Sea snapshots: Detecting harmful algal blooms
Environmental samplers may provide early detection of harmful algal blooms (HABs) in Puget Sound. This toxic algae is expected to increase as the climate changes, bringing with it new and potentially more severe outbreaks of shellfish poisonings.
Marine bird science in Puget Sound
Birds serve as useful indicators of ecosystem change and ecosystem health, biodiversity, condition of habitats, and climate change. Many people and organizations have their eyes on marine birds in Puget Sound.
Advances in technology help researchers evaluate threatened Puget Sound steelhead
New, smaller acoustic tags will allow scientists to track steelhead migrations in Puget Sound in ways that were once impossible. Will they provide answers to the mysterious decline of these now-threatened fish?
Eyes Over Puget Sound: Surface Conditions Report – June 27, 2016
Record-breaking warmer and fresher water in Puget Sound. May-June conditions are more unusual than last year. Recent rain brought river flows close to normal but water exchange in Puget Sound remains weak due to low Fraser River flow. Phytoplankton blooms and organic material are visible in some areas of Central and South Sound but not in others. Noctiluca, while absent in Central Basin, was
Mystery remains in deaths of young salmon
The Salish Sea Marine Survival Project has mobilized dozens of organizations in the U.S. and Canada to find an answer to one of the region's greatest mysteries. What is killing so many young salmon before they can return home to spawn? A series of talks at the 2016 Salish Sea Ecosystem Conference brought together some of the latest research.
Contaminants higher in resident 'blackmouth' Chinook
Many of Puget Sound's Chinook salmon spend their entire lives in local waters and don't migrate to the open ocean. These fish tend to collect more contaminants in their bodies because of the sound's relatively high levels of pollution.
