blooms dominate in Budd, Totten, and Eld Inlets.
Jellyfish begin to increase.
Northerly winds push algal blooms from Whidbey and Central Basins past Seattle

Satellite thermal imagery shows
patterns of near-surface mixing and injection of nutrients into the surface
layer. Glacial-fed rivers deliver glacial flour into Commencement Bay,
stratifying the water and supporting different colored phytoplankton blooms
(green, brown, and red).
Since the beginning of 2013, dissolved oxygen is
dropping below expected values.
