A particularly great day for the coast flight. Extensive Noctiluca bloom (confirmed by microscopy on 6-21-2011) in Central Basin of Puget Sound, red brown and turquoise blooms in South Sound. Decreasing dissolved oxygen (DO) values at Mukilteo and Manchester mooring stations.

Summer is here! Surface water temperatures have warmed to 14-15 °C. Widespread algae bloom in Main Basin. Puyallup River discharge is very large. Extensive phytoplankton blooms in Central and South Sound, large patches and strands of macroalgae in South Sound/southern Central Sound.

A Kaleidoscope of colors. Red-brown blooms in South Sound and Quartermaster Harbor, large patches of macro-algae in Central Sound. Latest bloom in Central Sound shows signs of fading as waters begin to clear. Oxygen is beginning to decline.

Warm temperatures, reminiscent of summer. Brown-red blooms in Carr Inlet and Budd Inlet. Macro-algae aggregations in Central Sound. Green bloom NE of Bainbridge Island. High surface fluorescence throughout northern Central Sound; highest values east of Port Madison. Oil spill in the South Sound.

Morning fog shows that fall is here! Warm afternoons with colder nights make cooler-than-normal conditions. Temperatures decrease and blooms fade as the summer growing season comes to an end. Brown-red blooms still in Carr Inlet and Budd Inlet. Green bloom near Squaxin Island.

Good conditions to be in the field Less rain, average temperatures and not much sun. Temperatures continue to cool and blooms fade. Algae bloom still in northern Quartermaster Harbor. Jelly fish in Budd Inlet.

Less rain and sun and colder temperatures. Conditions are challenging for crew and instruments. Large jelly fish patches in Inlets: Budd, Sinclair, and Case. Central Sound algae bloom continues as temperatures fall and oxygen is still decreasing at places. Freshwater water moves into Central Sound.

Cloudy, slightly warmer-than-average air temperatures, and higher-than normal river flows. Freshwater plumes extend far into the waterways. Jellyfish from fall still persist in Budd Inlet. Chilly surface temperatures and pulses of high CDOM waters in Central Sound.

Little sunshine, cold air temperatures, and higher river flows. Freshwater plumes extend far into the waterways. Chilly surface temperatures in Central Sound. First blooms begin in South Sound. A thinner freshwater layer at Mukilteo suggests a low discharge of the Snohomish river.
