We’ve just posted the latest aerial photos of Puget Sound surface conditions taken on Dec. 13.
This flight includes observations of Willapa Bay, Grays Harbor and Hood Canal.
The cover photo seen here shows Hood Canal looking south showing the Skokomish River estuary flowing into Hood Canal during high tide. At left, you can see parts of the town of Union.
On this day, the weather was warm, cloudy with weak winds from the south. Surface water temperatures ranged from 8.5-9.5°C. River flows were dropping below expected levels, yet the seasonal increase in freshwater can be clearly seen. Debris lines are numerous near river estuaries.
Algal biomass is down but jellyfish aggregations build up in terminal inlets, most notably in South Sound bays.
“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.
