Harbor Porpoise (Phocoena phocoena vomerina): Washington inland waters stock
Harbor porpoises were once common in Puget Sound, but had all but disappeared from local waters by the 1970s. Regular and numerous anecdotal sightings in recent years show that populations of these cetaceans are now increasing and may be approaching their former status. The attached document from NOAA Fisheries describes harbor porpoise numbers and their geographic range in Puget Sound as of 2011
Eyes Over Puget Sound: Surface Conditions Report - March 24, 2014
River flows are above normal and air temperatures are increasing slowly. The spring phytoplankton bloom is slow to develop with visible blooms limited to smaller bays such as Sequim and Bellingham Bays. Noctiluca observed in East Sound on Orcas Island, coinciding with high numbers of jellyfish. Debris lines are mostly confined to Hood Canal. Pockets of colder water observed in Central Sound and
Tidal energy in Puget Sound
Scientists have identified the strong underwater currents of Puget Sound's Admiralty Inlet as a potential source of electricity for nearby utilities. The following article describes some of the basic principles and mechanisms of tidal energy.

The Puget Sound Model
The Puget Sound Model was designed and built in the early 1950s at the University of Washington School of Oceanography as a research and teaching tool for understanding Puget Sound circulation patterns.
Reducing the risk of PCBs in sediments
A 2014 paper in the journal Water Research sheds new light on a novel ‘in place’ treatment option that effectively lowers risk by reducing the activity of PCBs in sediment.
Water Undone: The Efforts to Save the Puyallup River Watershed

Host demography influences the prevalence and severity of eelgrass wasting disease
A paper in the February 2014 journal Diseases of Aquatic Organisms examines the effect of leaf age on wasting disease in eelgrass across sites in the San Juan Archipelago. Co-author: Encyclopedia of Puget Sound topic editor Joe Gaydos.

Salish Sea Hydrophone Network and Orca Network
The Salish Sea Hydrophone Network and Orca Network are two citizen science projects dedicated to furthering our understanding of abundance, distribution, behavior, and habitat use by the endangered population of Southern Resident Killer Whales, also called orcas. The Hydrophone Network lets the public listen for orcas through their computers and phones, while the Orca Network gathers and
