The document provides an overview of marine monitoring activities in Puget Sound for February 27, 2012. It includes summaries of aerial photography observations, ferry and satellite data, weather conditions, and mooring data. Aerial photos showed river plumes extending into central Puget Sound and the first signs of algal blooms in south Puget Sound. Ferry data indicated localized areas of high colored dissolved organic matter from increased river flows. Weather had been increasingly colder than normal with low sunshine. Mooring data showed a thinner freshwater layer reflecting low discharge from the Snohomish River.
After 2-years of conditions favorable for water quality, with colder temperatures and higher oxygen, Puget Sound water conditions are closer to expected again. This year phytoplankton blooms and seasonal oxygen maxima are notable, while extensive Noctiluca blooms showed up early following a period high freshwater inputs and milder weather conditions. The Fraser River sediment influence is very strong north of San Juan Islands and warm, fresh water is entering Central Puget Sound from Whidbey Basin. In the past few weeks river flows and air temperatures have been higher than normal and now are decreasing.
Warmer and sunnier days result in higher than normal river flows from the Skagit and Nisqually. Biological activity in the water column is high. Abundant organic surface debris in Hood Canal, Padilla Bay, and many Inlets. Red-brown blooms in South Sound, Discovery Bay, and regions of Bellingham Bay. Different blooms in Skagit Bay, Padilla Bay, and Sinclair Inlet. Jelly fish are numerous in all southernmost South Sound Bays. Hood Canal remains cold but Puget Sound-wide temperatures are now warmer and less salty. Data from the Victoria Clipper and our sampling in the Strait provides important information on water exchange with the ocean.

Sun and high air temperatures warrant en route ozone measurements for model validations. A furry visitor takes a rest on the float plane. Spotlight on our pilot, Joe Leatherman. High river flows lead to striking fronts of turquoise-colored water carrying glacial flour in many northeastern regions. Satellite and aerial images show widespread phytoplankton blooms in Whidbey Basin, Hood Canal, South Puget Sound, and West Bay of Orcas Island. Numerous large debris patches in Hood Canal, Central Sound, and South Sound Inlets. After two years of colder temperatures and higher oxygen, Puget Sound waters are returning to expected or lower dissolved oxygen levels.
The weather changed from cool, cloudy and southerlies, to sunny warm conditions and light northerly winds on Mother’s Day. At the water surface, blooms and large debris lines occur in Bellingham, Padilla, and Samish Bays, Hood Canal, East Sound, and the Straits, as well as the finger inlets of South Sound. Large amounts of sediment-laden water from Port Susan are flowing into Central Basin. Turquoise water mixing to the surface in places around the San Juan Islands. After some trouble-shooting of the hardware and communication system, we will resume collecting Victoria Clipper data next week. Meet Eyes Under Puget Sound: Sediment Monitoring Program at Ecology.
Air temperatures have been slightly warmer and river flows are higher. Blooms are present only in Whidbey Basin and isolated bays. The water column otherwise is relatively clear. Sediment rich water is entering from the Stillaguamish River. Debris lines were visible in Hood Canal and North Sound. Multiple reported oil sheens seen in Lake Washington Ship Canal. Generally, the year 2014 started colder and saltier throughout Puget Sound. Oxygen is lower in Whidbey Basin, Central and South Sound, but higher in Hood Canal. Upwelling favorable conditions stimulate a spring phytoplankton bloom off the Washington coast.

For the last week sunshine was low and rivers and air temperatures have been higher than expected due to prevailing southerly winds. Heavy rains have resulted in long foam lines and large river plumes that are filled with sediment. Jelly fish patches have persisted through the winter in smaller bays. Are higher oxygen conditions seen over the last 2 years starting to disappear? We were busy in 2012 and spooled out 37 miles of CTD line to explore the depths of our estuaries!
A stunning view of a second large Noctiluca bloom captures the attention of many living near Puget Sound. Favorable conditions support several regional phytoplankton blooms. Red-brown blooms in Port Townsend, Discovery Bay and Bellingham Bay. Large algal mats or organic material particularly in Samish Bay. Jellyfish patches increasing in Budd, Totten and Eld Inlets.
Air temperatures are warm and Puget Sound continues to show record high water temperatures. Some rain has returned to our region, yet river flows remain unusually low. Puget Sound is saltier than normal allowing oxygen-rich surface waters to more easily mix to greater depths. Lower oxygen was measured only in the Coastal Bays, Hood Canal, and South Sound. Large jellyfish aggregations continue in South Sound, the Kitsap Peninsula, and East Sound (Orcas Island). Sediment plumes in Bellingham Bay form unique patterns. Warm waters and sunny conditions fostered green tides, raising a stink along some local beaches.
Puget Sound is starting to normalize in response to fall conditions with cooler air temperatures, rain, and recovering river flows. We are seeing fewer algal blooms, jellyfish, and macro-algae as salinities become more normal. Yet warm waters persist and El Nino and the Blob are likely to affect Puget Sound throughout the winter. The Nisqually River fared better through the drought than other rivers and best management practices have been improving its water quality. EOPS and ferry monitoring gain recognition with a national award for innovation!

Unusually warm water temperatures continue in central and south Puget Sound. River flows remain lower than normal, especially the Fraser and Skagit rivers. Thus, with estuarine circulation much weaker, Puget Sound waters stay put. Mats of organic debris persist in Central Sound near Port Madison. Red-brown and brown blooms are now very strong in southern inlets and jellyfish patches are exceptionally numerous and large. Explore media coverage of unusual Puget Sound conditions including jellyfish.

Warm waters and sunny conditions fostered green tides, raising a stink along some local beaches.
Unusually warm water temperatures continue in central and south Puget Sound while Willapa Bay returns to expected water temperatures as a result of stronger coastal upwelling. Extensive mats of organic debris develop in many places, particularly in Central Sound overlapping with a fading Noctiluca bloom. King County confirms Noctiluca and shares plankton species information. Red-brown and brown blooms are going strong in southern inlets and around the San Juan Islands. Our inspiring WCC Intern gets on boats, into the air, and to the lab.
Record warm water temperatures and low oxygen continue in Ecology’s Puget Sound marine monitoring station network. Record low stream flows result in visibly low river discharge into Puget Sound, in particular for the Puyallup River. Abundant sun and unusually warm water temperatures fuel phytoplankton blooms in many areas. Bright orange Noctiluca blooms are surfacing in the Commencement Bay area and around Port Madison. Finger inlets of South Sound support extensive patches of jellyfish.
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!
Puget Sound is feeling the heat! Starting in October, temperatures are the highest on our record since 1989. Salinity and oxygen are much lower. Recent rains have rivers flowing high. Aerial views show dramatic sediment loads from rivers mixing into otherwise blue water. But don’t be fooled – by summer, snow-fed rivers are expected to run significantly below normal, with implications for Puget Sound water quality. For details, explore the special Drought Effects segment. Spring blooms are visible only in some confined bays. Jellyfish are going strong in finger inlets of South Sound. Glimpse Puget Sound’s glacial history.
The ocean and air remain warm with sunshine and dry weather across the region. As a result, Puget Sound is a lot warmer going into the new year. Hood Canal is responding with temperatures warmer than previous measurements, breaking its low temperature stint. First signs of growing phytoplankton are coloring the water green. Patches of jellyfish are overwintering in finger inlets of South Sound. Tidal fronts and suspended sediment are visible amidst the stunning San Juan Islands scenery. A sediment-rich water mass is trapped in Rosario Strait. Check out the South Sound Estuarium and the many reasons we love Puget Sound!
Warm air and water temperatures and offshore winds have persisted since fall. Numerous and sizable jelly fish patches are still present in southern inlets of Puget Sound. Coastal waters were colored in shades of gray to brown by sediment and humic substances. Phytoplankton blooms were restricted to the surf zone. We were treated to artful views of meandering sloughs and gullies on exposed mud flats during low tide in Willapa Bay, interspersed with the geometry of shellfish management. Brown pelicans: a story of recovery.
The year 2014 in pictures: In 2014, Puget Sound and Hood Canal behaved distinctly different in temperature and dissolved oxygen. In Puget Sound, generally warmer conditions, abundant and diverse algal blooms, and large pools of organic material persisted along with lower oxygen, high jellyfish abundances, and a lot of suspended sediment. On the other hand, Hood Canal was colder, more oxygenated, and algae blooms were rare. People and planes: past and present.
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.
At the end of summer, water temperatures are still high, and salinities and dissolved oxygen are low in Puget Sound. Both sea surface temperature and upwelling off the coast are elevated (PDO and Upwelling indices) and the the Fraser River flow is low. This combination makes it an interesting fall. Very dense and large patches of jellyfish appear in finger inlets of South Sound. Red-brown blooms also remain strong in South Sound.
Sunshine and warmth continue into September. Upwelling is higher, yet low Fraser River flow reduces the likelihood of low-oxygen water moving into Puget Sound. Dissolved oxygen remains relatively high in Hood Canal and is lower elsewhere. Satellites show relatively warm water in the Strait of Georgia and Whidbey Basin and an extensive offshore bloom. Water temperatures also remain high in South Sound were red-brown plankton blooms and large smacks of jellyfish adorn the water surface. Explore what frequent blooms in smaller bays can tell us.
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.
Puget Sound conditions are normalizing after seven months of lower oxygen. Calm, dry, cool, and foggy mornings abruptly changed on October 28 to sun and strong northerly winds. Red-brown blooms and abundant jellyfish in south Puget Sound inlets appeared as we flew to the coast. Blooms were still visible near ocean beaches and inner bays. Grays Harbor had abundant surface debris with green algae in North Bay. We spotted red-brown blooms in rivers and sloughs in Willapa Bay, as well as schooling fish near sandbanks. Many patches of suspended sediment appeared in shallow water unrelated to tidal currents and remain unexplained.
The year 2013 in pictures: Low oxygen conditions persisted from January into August and broke a two year anomaly of more favorable water quality conditions (lower temperature and salinity and higher dissolved oxygen). Dramatic Noctiluca blooms appeared one month earlier than normal (May), lasted for two months and coincided with lower oxygen. Large jellyfish patches persisted over the winter but then were less visible for the rest of the year. Large drifting algal mats appeared in August.
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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Marine Flight 4 (South Sound)
The weather this month made getting our last flight out very
unpredictable. Luckily, there was a break in the weather on Monday and we
were able to get it done. It turned out to be a stellar day for sampling! It
was clear with some sun but cold with wind 10kts or below. Everything was
working great (including field crew) and we successfully worked our way
through all 10 stations. The Olympics looked particularly gorgeous with a
Mya and Laura ready to go! dusting of snow in the foothills.
We started a new collaboration this month with Donovan
Rafferty from Ecology’s Air Quality Program. We will be taking his ozone
analyzer along on flights to sample the air we pass through looking for
ozone plumes. Ozone in the lower atmosphere is a pollutant and also acts as
a greenhouse gas. It can cause eye and respiratory tract irritation, as well as
damage to plants by inhibiting photosynthesis and growth. Monitoring for
ozone can help us understand where it comes from and in what
concentrations.
Donovan has rigged up a special box to hold the ozone sensor, a
fan, a battery pack and a GPS unit. A GPS receiver is strung through to the
Olympic Mountains near Lilliwap front window of the plane and tubing which connects to the analyzer is
threaded out of the cabin vent to “sniff” and gather data. We are in the
testing phase right now. We want to be ready to collect quality data this
summer when ozone plumes can be found in our more urban areas.
Collaborations like this provide more data for the public and managers
without additional costs. It also makes our time in the plane even more
valuable and expands the contextual envelope for our own data.
A sharp clam shell gave us yet another flat tire!

Current Conditions:
Localized areas of high colored dissolved
organic material (associated with higher
river flows); surface temperatures are
7-8 °C throughout Central Sound and the
Strait of Juan de Fuca.

CDOM fluorescence as
an indicator of
freshwater influence in
Central Sound
A primary source of Colored
Dissolved Organic Matter
(CDOM) to Puget Sound is
from rivers.
Pulses of colored water have
been seen making their way
from Whidbey Basin into
Central Puget Sound,
associated with recent rainfall
and high river flows.
30. Mooring observation and trends
Field log Weather Water column Aerial photos Ferry and Satellite Moorings
Go to our mooring site at: http://www.ecy.wa.gov/programs/eap/mar_wat/moorings.html
Summary: On February 19 the freshwater layer thickness was low reflecting the Snohomish
discharge minimum (see previous page).
The mooring report is currently limited to describing the thickness of the freshwater layer
between Whidbey Basin and Central Basin.
Daily average depth of the 28.55 isohaline at Mukilteo
We track the depth of the isohaline
28.55 (±0.05) and measure the
thickness of the freshwater layer at
our Mukilteo station. The sensor
experiences tidal pressure variations
of 11.8 to 15.6 dbar.
