Press Release : CANA 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.

Officially 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 reflectsour 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.

 

Richard Neufeld

“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.

Glen Darou

Clean 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.”

Pearson 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.”

Second 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.

Solaster stimpsoni: Stripped Sun Star–The Race Rocks Taxonomy

This is a frame taken from the video beside. The blue color is because white light does penetrate to a depth of 8 metres, so only the parts of the picture that are illuminated from the video light show the true colors.. Note in the video how objects appear to change color when illuminated, but, they don’t actually do so. In the foreground is a broooding anemone , red with a band of babies at its girth. The pink coral is hydrocoral.

“Invertebrates at Race Rocks” is an introductory piece on a few of the invertebrate phyla. This was one of the first hinted streaming videos done by the Pearson College divers in April 2000. There is a good section on Soalaster Stimpsoni in the film. It was taken by Rowena and Shamsher on a Sony Digital camera, and edited by Hannah and Garry on a G4 Macintosh Computer using iMovie.

 

Physical Description
It has 8-12 arms, but usually it has 10 arms, which has length is about 23 cm. The diameter about 20 inches (51 cm). And the central disc about &Mac185; of total diameter. It&Mac226;s mouth just below the central disc. And, as the common sea star, it uses its tube feet which under main arms to move.

Global Distribution
This kind of sea star could be found at Bering Sea to Salt Point California (Trinidad Head, Sonoma Country, Kodiak Island and Oregon) and Pacific Northwest (Sunrise Beach and Gig Harbor).

Physical Description
It has 8-12 arms, but usually it has 10 arms, which has length is about 23 cm. The diameter about 20 inches (51 cm). And, as the common sea star, it uses its tube feet which under main arms to move.

Habitat
This sea star is possible to find at rocky bottoms but sometimes in sand or in the lowest zone.
Domain Eukarya
Kingdom Animalia
Phylum Echinodermata
Class Asteroida
Order Spinulosida
Suborder Eugnathina
Family Solasteridae
Genus Solaster
Species stimpsoni
Common Name: Stripped Sun Star, Sun Star, Stimpson’s
Feeding
This animal is a carnivore. It usually feed at sea cucumbers (the most favorite foods), tunicates, lampshells, sea pens, brachiopods, holothurians, sea squirts and nudibranch.

Predator
The predator of this animal is Sunflower Star ( Solaster dawsoni).

Reproduction
It reproduces sexually. It is breeding from February to March. Gametes are discharge into water. The eggs then become larvae and start to metamorphosis for about 40-50 days.

Interesting Thing
It can curl its arms up over its body to take on a spherical shape. This allows it to tumble across the seafloor in the along-shore currents.

Diodora aspera: Keyhole limpet– The Race Rocks Taxonomy

 

Keyhole limpets have a distinctive mantle-covering response when they are approached by a predatory sea star such as Pycnopodia.sp

Physical Description:

it has a small oval opening at the top of its short, conical shell. Although the keyhole limpet superficially resembles “true” limpets, its soft anatomy reveals an important difference. True limpets draw water into their mantle cavity on the left side, pass it over a single gill and discharge it on the right side. Keyhole limpets draw water in both sides, where it flows over paired gills before flowing out through the “keyhole” aperture at the peak of the shell. Size: Length is about 75 mm


Global distribution:
The Rough Keyhole Limpet can be found anywhere in coastal regions from Afognak, Alaska, to Baja California. It is found primarily in low intertidal areas, and has been seen up to 40 feet subtidally in the south (Morris et al. 1980).
Habitat:
The Keyhole Limpet clings tenaciously on and under large rocks in the sub to low intertidal. They can also be found on large kelp stipes. Their strong foot allows them to thrive in some intertidal areas where turbulent wave action is prevalent.

Domain Eukarya
Kingdom Animalia
Phylum Mollusca
Class Gastropoda
SubClass Prosobranchia
Order Archaeogastropoda
Family Fissurellidae
Genus Diodora
Species aspera
Common Name: Key-hole limpet
Feeding: This particular limpet is an omnivorous grazer. It feeds by scraping rocks with its radula. Various bryozoans are its food of choice, but it also consumes algae, as well as some sponge species.
Predators:
Sea stars, the limpet responds by raising its mantle up over the outside of its shell, a behavior that may prevent the sea star from gripping the shell surface.
Reproduction:
Keyhole limpets have separate sexes, and sexually ripe individuals can be found during any season of the year. Eggs and sperm are released into the water in mass quantities and larval settlement ensues.
One interesting Fact: Recent studies suggest that this animal’s unique apical opening is not only associated with sanitation, but also plays an important role in inducing passive flow through the mantle cavity. In studies where the keyhole of Diodora aspera was blocked (either naturally or experimentally) no evidence of damage to the mantle cavity or associated organs was found. In these experimental trials, water entered ventro-posteriorly with respect to the gill tips, and exited over the head region (near the anus). The apical opening proved unnecessary as a means of waste removal. Researchers did find however, that the keyhole played an essential role in allowing water to flow passively through the mantle cavity. Thus, it is thought that this function of the apical opening may have been just as significant as its role in sanitation in terms of limpet evolution

Elassochirus tenuimanus The Race Rocks Taxonomy

Domain Eukarya
Kingdom Animalia
Phylum Arthroppoda
Class Malacostraca
Order Decapoda
Family Paguridae
Genus Elassochirus
Species tenuimanus
Common Name: Wide-hand hermit crab

In this video, Elassochirus has been disturbed from eating a limpet (Collisella instabilis). It recovers and returns to eating. Note the colouration of the appendages of the hermit crab. Also note that one arm is much wider than the other. The Collisella which normally has a pale shell, is encrusted with the pink algae Lithothamnion.

General Description:
Named as wide-hand, this species hermit crab has a large and flattened right side of chela, carpus and propodus more than its left side. The right cheliped has a wider carpus than it is long. The walking legs have colours of white, reddish brown and purplish-blue on its merus.

Size:
The exterior length is up to 42 mm (1.6 inches).

Natural History, Habitat and geographical and depth range:
Mud, sand, shell bottoms, and especially rocks. The depth range is intertidal (infrequently) to 388 m (1272 feet). For the geographical range, the hermit crab lives in Bering Sea and Aleutian Islands, from Alaska to Washington, and the northwestern Pacific.
Ovigerous females in Washington usually appear from August to May.  Larvae produce from March to May and Planktonic are in last months of the year.

Behavior
When the animal retreats inside, the right claw is used to block the access to the shell itself. The crab bents this claw beneath the body while walking.

Falco peregrinus: Peregrine falcon –The Race Rocks Taxonomy

ryanperegrine

This photo was taken on Race Rocks by Ryan Murphy in December of 2008.

See all the posts on this website with observations of Peregrines

Domain: Eukarya
Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Aves
Order: Falconiformes
Family: Falconidae
Genus: Falco
Species: peregrinus
Common Name: Peregrine falcon

Unusual footage taken by Pam Birley using the remote camera 5 of a falcon eating a seabird. Also see similar sequence on right below..

 

The Peregrine falcon, Falco peregrinus, is a bird of prey (or raptor) which has captured the attention and imagination of ornithologists and bird-watchers alike for several thousand years. With a body length of 15-20 inches and a body weight of 1.25-3.75 lbs, the falcon is built specifically for travelling at high speeds (up to 180 m.p.h.) in order to catch its prey. The name Falco peregrinus is derived from the Latin falx, or sickle-shaped, and peregrinus, meaning wandering. It is unclear whether the former is derived from the shape of the bird’s silhouette in the sky or from the shape of its beak, but the latter name comes undoubtedly from its propensity to migrate great distances.In the picture of a Peregrine Falcon and Bald Eagle from his Flickr site, Ryan Murphy said
“This was amazing to witness in person, I regret not having been able to capture it better than this! Just before this the eagle rolled backwards towards the chasing falcon… awesome aerial battle!”
Predation
Two sequences of pictures from Race Rocks below have been taken by Pam Birley showing the peregrine eating a shorebird.and a sea gull. Though peregrine falcons, like other birds of prey, are considered to be near the top of the food web, they are not completely free from predators. Great horned owls and golden eagles have been known to attack them. Humans have also been known to take their eggs in hopes to raise the falcons for hunting purposes.
As top predators, peregrine falcons play an important ecosystem role in regulating the populations of their prey.
Habitat
Peregrine Falcons prefer open habitats such as grasslands, tundra, and meadows. They nest on cliff faces and crevices. They have recently begun to colonize urban areas because tall buildings are suitable for nesting in this species, and because of the abundance of pigeons as prey items.
Peregrine falcons prey almost exclusively on birds, including mourning doves, pigeons, shorebirds, (see slide shows above) waterfowl, and smaller songbirds. They will also eat small reptiles and mammals. Although peregrine falcons capture their prey with their claws, they generally kill prey with their beak.The photos for this slide show and video were taken on the remote camera 5 at Race Rocks, by Pam Birley operating the camera from Great Britain. Pam had observed the peregrine falcon on various perches around the island in the mornings for several weeks in October and November. Her persistence paid off on November 17, 2005. Pam wrote in her e-mail ….”Today we had just returned home .. I just came up to the computer, switched it on and there was Perry with his breakfast….I really caught him in the act of devouring his prey today!

PEREGRINE FALCONS AT RACEROCKS: OCTOBER, 2004

Pam Birley of Leicester England captured some of the pictures remotely on robotic camera 5 and Mike Slater, our reserve guardian took the pictures of the antenna perch on the towerPam was interviewed recently about her wildlife viewing on racerocks.com
ref: Anderson, Charlie, “Live Wildlife for your Living Room “,
The Province (newspaper) , Vancouver, B.C. ( Sunday, Nov.21, 2004)

Conservation Status
Peregrine falcons have suffered due to their dangerous position atop the food chain. Pesticides accumulate in small (not lethal) quantities in the tissues of small birds and mammals, but become concentrated enough in predatory birds, such as falcons, to kill them or render them incapable of producing offspring. Organochlorine pesticides (DDT and dieldrin) have been proven to reduce the birds’ ability to produce eggshells with sufficient calcium content, making the egg shells thin and more likely to break. Peregrine falcon populations dropped greatly in the middle of the 20th century, they were threatened worldwide by the increasing use of pesticides. All breeding pairs vanished in the Eastern United States. A successful captive breeding/reintroduction program, combined with restrictions in pesticide use, has been the basis of an amazing recovery by peregrine falcons. Now the use of many of the chemicals most harmful to these birds is restricted. It is not yet restricted in the areas of Central and South American where many subspecies spend the winter. After having been on the endangered list since 1969, the incredible recovery of Peregrine Falcons has become a perfect example of how effective human conservation can be. In the 1990’s they were taken off the lists of endangered species in the United States.

Jan 25, 2010 Brian Mury sent this link to a set of images he took from Camera 1 on the top of the tower. The falcon is perched on the FM antenna which is used by Environment Canada to transmit anemometer readings from the top of the tower.
