What “Eyes Over Puget Sound” saw on Aug. 21

By Sandy Howard

"Eyes Over Puget Sound” found continued warm air temperatures on Aug. 21, 2013, but less sunshine in the north, and increasing river flows in the past week.

Red-brown blooms were abundant in all inlets of South Sound and the Kitsap Peninsula. Large algal mats and floating organic material persisted in Hood Canal, Central Sound, Sinclair Inlet and Padilla Bay. Jelly fish were less abundant. Effects of glacier fed rivers were strong.

LANDSAT 8 continues to provide valuable near-surface temperature estimates for Puget Sound. Low-tide imagery provides rare glimpses of beautiful braided channels criss-crossing Whidbey Basin river deltas.

After two years of favorable conditions with colder temperatures and higher oxygen, Puget Sound waters are turning again to conditions of lower dissolved oxygen.

“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.
