Personal Field Impression
During the summer, boaters and beachgoers may see large islands of green algae on the water and on the
beach. These algal mats may contain a menagerie of seaweed, seagrass, eelgrass, and debris. The “green tides”
can be a visible sign of eutrophication in coastalenvironments which then negatively effect water quality. The
algal mats can also impact human health. When the algae decompose, they give off hydrogen sulfidegas, which
is an irritant and a chemical asphyxiant(causing breathing difficulty). Itcan lead to headaches, fatigue,
dizziness, and poor memory. If you smell rotten eggs at the beach, it might be fromgreen tides.
Algalmats decomposing on the

Boaters beware!Floatingalgal mats
can also trap debrissuch as logs.

Natural Influencesleadingto 9-21-2015
Summary:
Air temperatures haveremained
warmer than normal across
western Washington since March
of 2014.
Precipitation levels were
generally abovenormal in
western Washington during
August; rain was episodic.
Sunshine has generally been
abovenormal.
River flows arebelow normal,
especially for the Fraser and
Skagitrivers to the north.
Upwelling has returned to normal
and the PDO remains in the warm
phase.

UnusualPugetSoundconditionsexplained
In2014, a massive pool of warmwater developedinthe NE Pacific (the Blob). Duringthe summer of 2014,Blobwaters
were held offshore by the process of upwelling,as northerly winds movedsurface watersoffshore to be replacedby
cooler upwelledwater. This bufferedthe coast. Inthe fall of 2014,northerly winds subsided and the Blobmoved
onshore,entering Puget Sound on a massive scale.
Fraser River is the largest freshwater source for the Salish Sea - significantlyaffectingestuarine circulation
Higherthan normal
Lower thannormal
Expected
As of Aug 2015
(left), the Blobis
sitting offshore,
separatedfrom
the coast by a
thin band of
cooler,upwelled
water,like in
summer of 2014. Estuarine circulationis now weak since the snowpack-starved
rivers have recordlow flows. This reduces chances tobringcool,
upwelledoceanwaterinto Puget Sound.
The freshet of the FraserRiver and
other rivers flowinginto Puget Sound came much
earlier due to the mild winter, resulting in below
normal flows. Water that is inPuget Sound will
therefore remainlonger. That means more warming
and, potentially,anaccumulationof pollutants.

approximate reconstructionofthe surface

Debris:
Debris canbe distinguished into natural and
anthropogenic debris floatingat the surface
sensu Moore andAllen (2000). The majority of
organic debris in Puget Sound is natural and
mixedwith discardedman-made pieces of
plastic,wood,etc. Fromthe plane,we cannot
differentiatethe quality of debris at the surface
and therefore,call it forreasons of practicality
just “debris”.

Summary: The Mukilteo mooring station continues to havemonthly water temperature that is
higher than the pastfive years. Mean daily temperatureand salinity are becoming more variable.
River flows remain low and minimal.

In September, water temperature remains warmer
than the pastfive years, salinity is about normal,
and dissolved oxygen declines slightly. Seasonality
of each parameter remains apparent.
Please note that data are provisional. Data are in GMT.

Our mooring station in Mukilteo is located in
Whidbey Basin near Everett. Itis also
located at the transition between Possession
and Central Sounds at a depth that is
influenced by the Skagitand Snohomish
River discharges, prevailing winds, and tidal
mixing.
As the largestregional contributor of
freshwater to Puget Sound, understanding
the timing and magnitude of the Skagit River
flow is important. Southerly winds coincided
with increased river flows.
We presentdaily means for the past31 days.
Data are plotted in Pacific Standard Time.
Wind data are fromPaine Field in Everett.

Warmer temperatures and a higher proportion of winter
precipitation falling as rain, rather than stored as snow, will
reduce the amountof water stored as snow in the Skagit
Basin overall.
The retreat and loss of the glaciers (e.g., Easton Glacier) will
continue to effect summertime low flows (400 billion gallons
of reduced water supply since 1993) in the SkagitRiver basin.
