Marine Water Quality Monitoring

Water Surface Conditions

The water surface reflects many processes that occur below the surface. Within two days of observation we report on visible features near the surface. These range from algae blooms, oil sheens to whales. Covering the scale from satellites, aerial photographs and measurements in the water we offer broader context for our observations.


We release the EOPS report within two days of observation.
EOPS gives you news on current surface conditions of Puget Sound. EOPS is a pdf document and organized by sections to reflect different scales of observations.

Ecology's Marine Monitoring Unit conducts a variety of marine observations, including monthly sampling at 40 core monitoring stations. We use a floatplane to cover our widely distributed station network. We take photos of Puget Sound water conditions during a routine transit flight between the Kenmore base and Olympia. “Eyes Over Puget Sound” is the result, and an example of how we are optimizing our resources to monitor Puget Sound. “Eyes Over Puget Sound” combines high-resolution photo observations with satellite images, en route ferry data between Seattle and Victoria BC, and measurements from our moored instruments.
