A 2019 report from the University of Washington Puget Sound Institute examines the application of 'resilience thinking' to Puget Sound protection and restoration.

New research shows that warmer and more acidic oceans could lead to shorter embryos and higher respiration in Pacific herring.

Sunshine and warm temperatures return after last week’s intense rain. The Puyallup and Nisqually Rivers are flowing high. Red-brown blooms and numerous patches of jellyfish remain strong in South Sound, Sinclair and Dyes Inlets, and Bellingham Bay, with brown-green blooms in Whidbey Basin. Macro-algae surface debris is very high in South and Central Sound. Hood Canal remains cooler but Puget Sound-wide temperatures are now warmer and less salty. Sea surface temperatures are above 15 °C, conditions favorable for some pathogens, and harmful algae blooms. Read about super colonies of by-the-wind sailors washing up on our shores.

The Washington State Department of Ecology has prepared a summary review of its Eyes Over Puget Sound surface condition reports from 2019. The year started with snow, and a summer drought kept river flows low. As a result, salinities in Puget Sound were elevated year round. Warmer surface water temperatures in spring gradually extended to greater depth by late summer. The spring bloom was strong, and South Sound provided optimal conditions for anchovies that showed up in high numbers. A coccolithophore bloom stained Hood Canal turquoise, and Port Angeles and Discovery Bay were colored red-brown by strong blooms. Noctiluca and macroalgae, both known eutrophication indicators in coastal regions, were abundant in Central Sound, and extended into South Sound and Whidbey Basin. Large numbers of jellyfish occurred in Quartermaster Harbor, Sinclair Inlet, and parts of Orcas Island.

The year 2016 in pictures: After two years of very warm air and record high water temperatures starting with the Blob (2015) and followed by El Nino (2016), temperatures have fallen and remain slightly warmer than normal in Puget Sound. Very low summer river flows (e.g., Fraser River) reflect climatic predictions for the NW. Record temperatures and low salinities occurred alongside observations of abundant jellyfish, floating macro-algae, and Noctiluca blooms. Surprisingly, only South Sound developed very low summer oxygen levels in 2016. In the fall, La Niña came with a punch, rain increased, and air temperatures dropped. Will this be an unusual La Niña?

The largest of the beaked whales, Baird’s beaked whales can grow to a length of nearly eleven meters and weigh nearly twelve thousand kilograms. Due to their preference for deeper waters, Baird’s beaked whales are somewhat rare in the Salish Sea with sightings mostly confined to the recovery of stranded animals.

A recent cold spell hits Puget Sound lowlands, interrupting this year’s warmer air temperatures. The warm ocean coincides with new maximum water temperatures observed throughout Puget Sound in October! Hood Canal’s higher dissolved oxygen and cold water anomalies are disappearing. November brings cold water from Whidbey Basin into Puget Sound with moderate levels of chlorophyll fluorescence. Abundant smacks of jellyfish in finger inlets of South Sound observed from our flight. Red-brown blooms remain strong in smaller bays of South Sound. Visible suspended sediments in the coastal estuaries from rain, wind, and waves. Playing in the water? Visit our BEACH program.

Warm waters from “The Blob” in Puget Sound combine with drought conditions as warm air has left little snow to feed the rivers. Water temperatures throughout Puget Sound are the highest in 25 years and oxygen is exhibiting record lows. High suspended sediment in the north is still coming in from the Fraser River. Otherwise, the surface waters appear very clear due to recent low river flows and weak blooming activity. A red bloom is present in Sinclair Inlet and in some confined bays. Patches of jellyfish, however, are going strong in inlets of South Sound and Sinclair Inlet. What does this all mean for salmon? Get to know some intertidal critters!

After weeks of clouds and warmer air, blue skies and cold temperatures set in. Strong tidal fronts and sediment-rich brackish plumes leave Whidbey Basin and move into Admiralty Reach. A pod of Orcas follows the edge of the plume heading north! Red-brown blooms continue in Henderson, Eld, and northern Budd Inlets. Long organic debris lines are numerous in northern Budd Inlet, Hood Canal, and in Central Sound north of Edmonds (Triple Junction). Conditions in the water column in Puget Sound continue to normalize after seven months of lower oxygen. Water is very clear for this time of the year, particularly in the north.

Habitat restoration was undertaken in 2009-2010 on lower Hansen Creek, Washington. The project converted 140 acres of isolated floodplain into 53 acres of alluvial fan and 87 acres of flow-through wetlands.
