PRESS RELEASE below……February 25, 2005 (Link to PDF version)-
ENCANA PARTNERS TO ENABLE PEARSON COLLEGE – ENCANA – CLEAN CURRENT TIDAL POWER DEMONSTRATION PROJECT AT RACE ROCKS, BC Victoria
– Thanks to an innovative partnership between Lester B. Pearson College of the Pacific,EnCana Corporation and Clean Current Power Systems Incorporated, Canada’s first free-stream tidal power project will be built at the Race Rocks Ecological Reserve, offshore of Vancouver Island in British Columbia. The project will enable the world famous marine park to tap into surrounding ocean currents and convert tidal energy to electric power for its needs beginning in early 2006. Making the announcement were:
Gwyn Morgan, President and CEO of EnCana,
Glen Darou, President and CEO of Clean Current,
Richard Neufeld, British Columbia Minister of Energy and Mines,
and Stuart Walker, Director of Pearson College.1gwynOfficially known as the “Pearson College – EnCana – Clean Current Tidal Power Demonstration Project at Race Rocks,” the project is enabled by a $3-million investment from the EnCana Environmental Innovation Fund.“EnCana is pleased to be a partner in this first-class, alternative energy project,” said Morgan. “Our investment in this B.C.-based unconventional environmental and power technology reflects our desire to tangibly encourage innovative energy solutions.” EnCana’s Environmental Innovation Fund was established to advance new technologies and solutions that improve environmental performance associated with consuming and producing energy. Commercial proceeds from financed projects will be re-invested into the fund to ensure their sustainability.1minister“The commitment by Premier Campbell in promoting alternative energy sources has helped British Columbia become a world leader in sustainable environmental management,” said Neufeld. “The province commends projects like this one, as they show our commitment to developing clean energy solutions that will benefit all British Columbians.” The multi-year demonstration project will involve the installation, operation and monitoring of a 65kW free-stream tidal turbine generator in the water near Race Rocks, a provincial ecological reserve located 10 nautical miles southwest of Victoria.1glencamClean Current is a private British Columbia-based company that designs and licenses technology that efficiently converts the energy of tidal currents into electricity. Clean Current’s proprietary technology consists of a horizontal-axis ducted turbine with a direct-drive variable speed permanent magnet generator. The turbine generator is equally efficient in both directions as the tidal currents reverse twice each day.“This Canadian technology is simple, efficient and environmentally friendly,” said Darou. “We believe it is highly exportable technology, with strong potential to succeed in international settings. Our company is delighted to have the support of EnCana, Pearson College, and technical partners AMEC, Powertech Labs Inc. and Triton Consultants Ltd.”Pears1stuarton College, one of ten United World Colleges worldwide, is the custodian of the Race Rocks Ecological Reserve, located three nautical miles from campus. Diesel-powered generators currently provide electricity requirements at the reserve. Students and staff will work elements of the tidal power demonstration project into their studies.“This is a terrific project for Pearson College, in that it supports our goal of making the ecological reserve a showcase for alternative, low-impact technologies such as tidal power,” said Walker. “We would like to thank Clean Current for their commitment to developing the technology and EnCana for the financial support that is making this demonstration project possible.”1studentSecond Year Pearson College student Alyssa Holland (year 30) concluded the presentation , by thanking the speakers. As a student involved in Environmental Systems and the diving program, she shared the enthusiasm she has for the resources of the area and emphasized the great importance she and other students attach to the effort of those involved in this project in the ongoing goal of producing energy sustainably.Below is the complete version of her speach:

text of speech by Alyssa Holland (year 30)

As I am both an Environmental Systems student and a member of the diving activity, Race Rocks has played a central role in the education Pearson has given me. Race Rocks is truly the ultimate living classroom, teaching all those who interact with it about the beauty and wonder of the natural environment, and about the importance of responsible environmental stewardship. It is a very special place that gives so much to the college and its students, and it is very gratifying to think how much the ecosystem will benefit from the Clean Current project.

For Pearson students, Race Rocks is much more than a group of islands. On one level or another, we all interact with it and benefit from it, and consider it part of our home. Whether through poking around in the inter-tidal zone for class, or working with a researcher from the University of Victoria 10 metres underwater, or staying on the island for a weekend to give its 2 full-time residents a break, we have built a connection with this magical place. As such, ensuring its health and protection are very important to me, and to the student body as a whole.

Pearson is by its very nature an innovative place – even the concept of a United World College is radical and still experimental. I can think of no better or more appropriate environment for such an exciting new technology as this to be implemented, as it truly embodies the spirit of innovation and idealism that makes Pearson College unique. This new turbine will stand as much more than a symbol of scientific progress; it will also be a concrete demonstration that even an ideal as difficult to live by as environmentalism can be successfully put into practice when we are innovative. That will be a lesson to guide both students and visitors for years to come.

BACKGROUNDER: (Link to PDF version)Race Rocks is a unique ecosystem located at the eastern entrance to the Strait of Juan de Fuca, three nautical miles from Pearson College and ten nautical miles southwest of Victoria, BC. The rocky outcroppings that form the Race Rocks group of islands are the visible summit of an underwater mountain and are washed daily by tidal currents that can run at up to seven knots. These swift waters are the lifeblood of breathtakingly diverse plant and animal life – recognized internationally as a treasured ecosystem. To First Nations people, Race Rocks was a banquet table in the swift flowing waters known to them as XwaYen. To early mariners it was a formidable hazard to be avoided. To fishers it was a haven for finding rockfish and halibut. To scuba divers it is an underwater paradise with thriving colonies of marine organisms. To generations of future researchers, college students and school children, it will be an awe-inspiring outdoor and virtual classroom.

Clean Current Power Systems Incorporated
Clean Current Power Systems Incorporated is a private British Columbia-based company that will generate electricity from ocean tidal currents. Clean Current designs and licenses technology which converts the kinetic energy of tidal currents into electricity with unprecedented efficiency. This electricity is renewable, predictable and creates no greenhouse gases. The tidal turbine generator units are deployed completely underwater and cause no visual impact on pristine marine environments.

Efficiency and operability in salt water are the key ingredients of a successful tidal technology. Clean Current’s tidal turbine generator is a bi-directional ducted horizontal axis turbine with a direct drive variable speed permanent magnet generator. This proprietary design delivers better than 50 per cent water-to-wire efficiency, a significant improvement over competing free stream tidal energy technologies. Operability is enhanced by a simple design that has one moving part – the rotor assembly that contains the permanent magnets. There is no drive shaft and no gearbox.

The turbine generator has a design life of 10 years (major overhaul every 10 years) and a service life of 25-30 years. During that time it will generate electricity with zero emissions, a minimal footprint on the bottom of the ocean and negligible impact on marine life.
The Pearson College – EnCana – Clean Current Tidal Power Demonstration Project at Race Rocks is an important step in the Company’s technology development plan aimed at early commercialization.

To ensure success Clean Current has enlisted the assistance of technical partners AMEC Americas Limited and AMEC Dynamic Structures Limited (both subsidiaries of AMEC PLC),Powertech, (a subsidiary of BC Hydro) and Triton Consultants Ltd.

The History of the Foghorn at Race Rocks

Posted on by

foghorn-1From the early 1980’s until January, 1997, fog or heavy rain impeding visibility in the eastern entrance of the Strait of Juan de Fuca would trigger three double tones per minute from the four trumpet shaped Airchime horns mounted on the South side of the engine room at Race Rocks.

racerocks.com Wins Prestigious Educational Award

Posted on by

Originally published in the Pearson College Newsletter, THE LINK September 17, 2004. Link no.66. 

No one who knows Garry Fletcher — and that includes almost every graduate of Pearson College — can doubt his passion for the environment. No one who has followed the development of the racerocks.com (now.ca) website, connecting the world with the marine protected area just beyond Pearson College, will be surprised that it was singled out in July for an award of excellence from the Commonwealth of Learning. The award recognizes the immense contribution of the website to non-formal distance learning.

“It was an opportunity to share our good fortune with the wider educational community,” Garry has commented on the way he has beamed the rich ecosystems of Race Rocks outward electronically to museums, schools, and all individuals interested in a close look at marine life. From anywhere in the web world it is possible to watch the sealions bask and swim, to see the interaction of abundant species, and to see divers below the surface interacting with requests from children far away. “Through technology we can introduce visitors to marine ecology – without the real visits that would damage a sensitive site.”

The web site racerocks.com was chosen for the following reasons by the jury:

• it is fitting for a variety of clientele needs in non-formal education in the very important area of the environment

• it has adopted a sound learning and instructional design, and

• it uses a variety of media which can be integrated in a flexible manner according to individual learning needs and interests

Garry Fletcher retired from Pearson College this summer after some thirty years of teaching Biology and Environmental Systems. He has not, however, gone far: he lives just down the road, and continues to pass through the college on the way to Race Rocks, the marine area for which he has been instrumental in gaining protected status, and for whose website he has just been highly honoured.

The presentation was made by Sir John Daniel, President of COL, to Garry Fletcher of Pearson College in Dunedin, New Zealand at the annual awards ceremony to announce the 2004 recipients of the Excellence in Distance Education Awards (EDEA).

Water Supply: The Desalinator System at Race Rocks

Posted on by

Race Rocks ecological Reserve functions as an isolated system. Fresh water for human use may only be obtained by processing sea water through the desalinator. Energy is generated through solar panels and backup generators.  The desalinator depends on these sources of energy to function. The more efficient the desalinator, the less energy is used. The students take us through the process:

The Tidal Cycle at Race Rocks and the Abiotic Effects of Tides

Posted on by

 

At Race Rocks we have a tidal range of about 3 metres.

For tidal Level predictions , from the closest station at Pedder Bay see this link

https://tides.gc.ca/en/stations/07080/predictions

 

 

 

The link below is for the Race Passage Current tables.  .. See this file for the result of original work done by Pearson College Divers assisting the Institute of Ocean Sciences in the deployment of the current meter to gather a year’s worth of data from which these tables are constructed. 

 

 

 

 

 
Marine Science teacher at Pearson College Laura Verhegge was interviewed on CBC radio about what was a “Negative tide”. Listen below.

 

The role of the moon is a major factor in determining the rise and fall of the tides.The view of it from Race Rocks in a full sky is often stunning. 

And of course the other component causing tides is the sun. See this file for Solar energy records for Race Rocks .  

 

 

See this file for the Abiotic Effect of Solar energy on Organisms at Race Rocks

 

 

THE ABIOTIC EFFECTS OF TIDAL LEVEL CHANGES:

The rich variety of life in the intertidal zones of Race Rocks provide habitat for many animals which have adapted to living part of their life exposed . “ANITA’S ISLAND” on the West side of Great Race Rocks provides an excellent example,  in the month of June when the tidal level often drops below zero datum so one can really appreciate the effects of the daily changing tidal levels on intertidal life. This island is actually a peninsula which you can walk out onto when the tides drop to -0.0m, but is totally submerged at high tide, (around 2.6 meters). You can often see the top of it from remote camera1  ( It looks black because it is covered with mussels.)

For several years in the 1990s  we did research with Dr. Anita Brinckmann-Voss on these low tides in June. We only had a half hour or so until the isthmus joining the island to Great Race Island was flooded however. Each year that we went out, Anita found a great many of the hydroid samples from which she identified for the Ecological Reserve.  

THE INTERTIDAL ZONE: The island is totally covered on every square centimeter with some form of life, either invertebrate or plant.

    • Those organisms nearer the top or in the high intertidal area, are more resistant to changing temperatures, and changing salinity. Exposure in a rain storm means they have to tolerate fresh water, and changing salinity.  On a hot sunny day , the surface temperatures can elevate quickly. 
    • Other hazards of this habitat between sea and land create an extreme environment for survival. Predation from Birds and other animals is possible when exposed at low tide , wheres the same organisms are exposed to predation from fish and predatory invertebrates such as sea stars when the tide is in. 
    • This zone also makes the organism vulnerable to pounding waves and surf, so built in resilience is necessary to hold on and remain attached , and not be crushed by the force of the water.
  • Living in this zone also leaves an organism exposed to wind driven foreign objects.. At Race Rocks drifting logs are often present on the surface and these can exert a powerful force when striking a shoreline, 
RESEARCH ESSAYS: The implications for an organism living at different elevations on the intertidal zone are very significant. Over the years several students have done research in the intertidal zone at Race Rocks and have examined how different organisms have adapted. Check this file for examples 
TIDEPOOLS: In our tidepool file , you will find an index with links to a set of tidepools where we have recorded the effects of the tide being out for different lengths of time. The abiotic conditions in the pools change significantly as the tide levels go up and down. Salinity and Temperature are especially variable and they influence the type of organisms that lives within the pools.
Intertidal TRANSECT Studies.We use transects to quantify the interrelations of organisms as they are distributed throughout the intertidal zone on the shore. Tidal levels are a major factor in determining this zonation. In this file you are invited to examine some of our data, and create your own transect baseline studies as well. They may have nothing to do with tides, but they can serve as an excellent record which you may use to base measurements showing change or stability of the ecosystem in the future
The Effects of CURRENTS. 

Tidal Currents are also a result of the tidal cycle . This file documents aspects of the currents at Race Rocks

Other tidal heights from along the coast of Vancouver Island and British Columbia

An interesting exercise is to compare the tidal heights at several locations around Vancouver Island. There is a significant difference, with times as well as tidal ranges varying depending where the station is located. There are many factors which determine tide levels, the most obvious being the stages of the moon and the position of the sun, but here you can see that geography has a major role to play as well.

APPLE : Partnership with racerocks.com

Posted on by

ARCHIVE: It is important to recognize that the early innovations in internet technology at Race Rocks  were made possible by the cooperation of a number of partners and sponsors . Apple was one of the important partners in collaboration for this educational application of the internet for the conservation of a sensitive ecosystem by promoting the availability of its unique ecological features to the world.
In June 2000, Apple first became a sponsor when APPLE CANADA recognized the significance of our project and loaned us a new Powerbook G3 500 for the two weeks of mobile webcasts in June 2000.

 

 

As a result of that initial support, Apple Canada sent us the same computer for our project in July 2000. At the New York MacWorld Conference in July, our presentation of a live underwater webcast from Race Rocks prompted an offer from The APPLE LEARNING INTERCHANGE for a partnership. The result was that the QuickTime live video streams were hosted by the Apple Learning Interchange over the Akamai Internet distribution network. We are extremely grateful to APPLE for this generous support. Live video streams have now been operating since the summer of 2000 thanks to tis initial support.

 

In October, 2000, APPLE hosted us for a presentation of the live Underwater QuickTime stream at the QuickTime Live Convention in California.

In March of 2001, APPLE Canada came to our assistance again with the generous
donation of a G4 Titanium PowerBook. We used this for our mobile webcasts and
for the creation of new archived video clips using the iMovie software. 

We must also acknowledge the commitment of the Apple representative Keith Mitchell who worked out of the offices in Texas and was also able to visit us to see the operation of our system at Race Rocks.

In June of 2002, The APPLE LEARNING INTERCHANGE opened its new gallery of featured exhibits and  racerocks.com was included on the ALI website as one of their exhibits.

 

 

In January of 2004, The Apple Learning Interchange upgraded the three computers and the Wireless Airports and they also assisted us with the purchase of a new Remote Control camera. We now have the equipment installed and providing improved Live Streaming Images as of the spring of 2004.

In 2004, three APPLE eMacs were supplied to webcast from cameras 1, 2 and 5. Webcasting from these cameras used QuickTime Broadcaster.
