About the Eyes Over Puget Sound monitoring program

Once a month, Washington State Department of Ecology marine scientists take to the air to obtain high-resolution aerial photo observations and gather water data at the agency's monitoring stations and via state ferry transects. This provides a visual picture of the health of Puget Sound, which they call Eyes Over Puget Sound or EOPS.

Eyes Over Puget Sound: Surface Conditions Report - June 17, 2013

A stunning view of a second large Noctiluca bloom captures the attention of many living near Puget Sound. Favorable conditions support several regional phytoplankton blooms. Red-brown blooms in Port Townsend, Discovery Bay and Bellingham Bay. Large algal mats or organic material particularly in Samish Bay. Jellyfish patches increasing in Budd, Totten and Eld Inlets.

Report: Sediment quality in Central Puget Sound

Sediment health in Central Puget Sound has shown a recent steep decline, according to a report by the Washington Department of Ecology. The report compares monitoring data over a ten-year period between 1998/1999 and 2008/2009.

Researchers monitored populations of benthic invertebrates, sediment-dwelling organisms that depend on an environment free of pollutants, as part of the Puget Sound
