Presentation by Allysa Holland to opening of Tidal Current Energy Project

Text of speech by Alyssa Holland (year 30) 

Tidal Current Energy Demonstration Project: Renewable Energy for Race Rocks

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.

Tidal Current Generator Experiment Announced

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.

Bangia fuscopurpurea : Race Rocks Taxonomy

combover3Description: This common red alga is especially noticeable on the surfaces of smooth boulders.  It grows as thin filaments of a rusty, purplish brown, or blackish colour.

As the tide ebbs, the filaments spread out over the rock in a way reminiscent of a few hairs artfully plastered down on a nearly bald head.
Habitat: On rocks in the upper and middle intertidal zones.
Pacific Coast Distribution:           Alaska to California.

Class: Bangiophycidae
Order: Bangiales
Family: Bangiaceae

Organisms categorized within the genus Pleurosigma appear all over the world, regardless of location.  The genus is one of the larger groups of diatoms, containing hundred of different species and also making it very difficult to identify exact taxonomy of organisms.

Thalassiothrix sp.

mixture of Thallasiothrix and several other diaton species from a plankton tow.

 

Thallasiothrix microscopic view

 

 

From Phyto’pedia Length (apical axis): 10 – 110 μm
Width (transapical axis): 2 – 4 μm
Height (pervalvar axis): 3 – 8 μm
Marginal areolae: 10 – 12 in 10 μm
(Cupp 1943, Kraberg et al. 2010)

Commonly found in nutrient-rich upwelling regions (Abrantes 1988, cited in Kobayashi and Takahashi 2002). Its presence indicates conditions of high productivity (Schrader and Sorknes 1990, cited in Kobayashi and Takahashi 2002). Optimal temperature ∼15 °C (Resende 2007). Salinity range from ∼12 – 33 (Demir 2007, Burns 1977).
