Eyes over Puget Sound

Once a month, we take to the air and travel by boat to obtain high-resolution aerial photo observations and gather water data at our monitoring stations and via state ferry transects. This provides us a visual picture of the health of Puget Sound, which we call Eyes Over Puget Sound or EOPS.

Eyes Over Puget Sound empowers you to:

  • See what is currently happening in Puget Sound.
  • See how weather and climate are shaping Puget Sound water quality.
  • Use Eyes Over Puget Sound as free educational material for your own endeavors.

Latest Edition

After a dry and sunny summer extending well into October, air temperatures are cooler than normal, and precipitation has increased, allowing rivers to regain strength. Despite a dry summer, Puget Sound is fresher this year than the past 17 years. As of September, warmer temperatures remained in South Sound. In October, surface water in the Straits, however, began to cool, and the influence of rivers can be seen in our ferry data. Leaves drift on the water in South Sound and smaller blooms are confined to inlets as the productive season winds down. Meet our new intern, and discover if Puget Sound really has sea spiders.
