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

Large-scale influences on Puget Sound, climate and streams

  • By March, regional impacts of large-scale climate patterns returned to normal conditions.
  • Air temperatures, precipitation, and coastal downwelling were below normal.
  • April brought abundant rain and rivers responded with higher flows.
  • The current snowpack is healthy, hopefully leading to normal streamflows through summer as the snow melts.
 What we saw in our marine water data
  • After large anomalies in temperature and salinities in the previous years, Puget Sound water conditions in 2018 are mostly as expected.
  • Hood Canal is the exception to the above statement. Anomalies in Hood Canal persisted longer and shifted in March to a pattern of lower temperatures and higher oxygen, which is beneficial to the aquatic food web.
 What we saw on our flight over Puget Sound
  • Sediment plumes carried in from rivers and field drainage ditches were visible in many places.
  • In this edition, you can see the strong red-brown bloom in Sinclair Inlet, a bright-brown bloom in Padilla Bay (Joe Leary Slough), and a bright green bloom in Bellingham Bay. All the blooms make it colorful in the Sound!
We are out there sampling sediments right now!  You may see our team on the water.
