Monitoring

Some of the most important fish in the Salish Sea food web are also the most mysterious. Researchers have only begun to understand how many there are, where they go, and how we can preserve their populations for the future. A University of Washington researcher describes how scientists are looking into the problem.

Gaps in regulations could allow invasive species to hitch a ride on ships and boats. We report on some of the potential impacts, and how state and federal agencies are trying to solve the problem. 

Concerns over the potential arrival of the European green crab have inspired a small army of volunteers. A search is underway for early signs of an invasion.

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 are thriving with blooms observed in many South Sound inlets. Macro-algae is seen piling up on beaches and drifting in Central Sound. Jellyfish smacks are numerous in Eld and Budd Inlets. Our fliers notice seals hanging out at the beach!

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. 

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.
