Ryan Murphy films underwater at West Race Rocks

Posted on by


This video was shot by the team of Pearson College divers while practicing for the live webcast for the QuickTime Live Conference in California- Oct 2000 .

On the 4th of October, a 5 member diving team brought the camera to West Race Rock to film the marine life there. Along with Red Sea Urchins (Strongylocentrotus franciscanus), Plumose Anemones (Metridium farcimen), and a Tiger Rockfish (Sebastes nigrocinctus) was a large school of Black Rockfish (Sebastes melanops). The camera crew for the dive was J.O. Dalphond, Hana Boye, and myself. Organism identification responsibility falls on me. Hinted streaming video time is 3 minutes 22 secs
My name is Ryan Murphy and I am a Year 26 Pearson Student from Newfoundland. I am doing the editing on this movie. I’m the diver with the blue snorkel signalling “OK” at the beginning. Garry, our Guru, is showing me how to do this in iMovie as this is my first movie, I hope you enjoy it.

The Johan Ashuvud Project, 2000

Victor David and Satoshi: For two weeks in May and June of 2000, Lester Pearson College graduating students, Victor Rakou, David Mesiha and Satoshi Kimura, and in the last week, Juan Manuel Alva and Martin Kryl, joined the sea gulls and stayed at Race Rocks running daily programs on a live camera, and broadcasting directly to the web. Faculty member Garry Fletcher worked with them for the daily webcasts from the shore and from underwater. Sponsorship for this week came from the Johan Ashuvud memorial fund.

The first big event was the Swiftsure Race Weekend. A camera was set up along with a supporting G4 computer in the top of the light tower. Two streams were broadcast, one to camera 4 on the website and a special experimental dedicated stream to Shaw Cable. This stream was of TV quality at 1Mbps and 21 FPS.

Our thanks to Kevin Sytsma of LGS for coming out to help setup for this 2 day broadcast and to Ken Dunham ( PC year 9) for reconfiguring the server from Ottawa in order to handle this experiment.

Each day at Low tide we set up in different locations around the island, always being careful to not disturb the nesting seabirds futher up on land. A Sony camera linked by Firewire to a G3 500 Mghz computer was located in the intertidal zone. From here, Audio and Video Signal went by the wireless Macintosh AirPort Link to the Science Centre. From here the signal traveled by Cat.5 cable to the top of the light tower where it was sent by radio to the Telus antenna at Lester Pearson College. From there it was webcast in live streaming video to the internet by a Macintosh G4 500.

Content through the week ranged from adaptations of organisms to the special ecological niches of tidepools and intertidal slopes, to First Nations use of resources and the role of community/ stakeholder participation in the Marine Protected Areas Pilot process.

The airport wireless base station was tried in a number of locations. We relied on David to find the best locations for connectivity. Best wireless transmission was achieved when we hoisted it up to the roof of the science house. The radio waves go through buildings but not through rocks!

Further editing for the video archives took place in the science centre in the evenings.

Chris Blondeau from Lester Pearson College joined us for a session on the care and maintenance of the underwater camera and housing. Chris is in charge of the shore-front at the college and is in charge of the SCUBA Diving program there.

We were also fortunate to have some visitors take part in the intertidal discussions we had on the islands. Dr. Jochen Kuum ( PC year 10) is seen here with Garry and diving with Satoshi and Victor Stephen Haggarty (PC year19) also participated above and below water. This video was made on the last dive

 

Carol Slater, who along with her husband Mike are the guardians of the MPA joined us to talk about the Black Oyster Catcher. We examined the trays of shells from last years midden of one nest. This parent bird was foraging off to the East of the dock where they hatched two chicks this year

Race Rocks viewed from the South at Rosedale Rocks Buoy.

One of the best parts in staying at Race Rocks overnight while doing these webcasts was the great sunsets. Sometimes you can view these on the remote control camera 1 and camera 5.

 

Live Transmission to the Internet from Underwater-2000

Posted on by

n June 2000, Lester B. Pearson College divers stayed at Race Rocks for two weeks, for the Johan Ashuvud Week doing live underwater transmissions to the internet. This video is a sample of scenes from the live webcast. It shows some of the colourful invertebrate life at 8 meters depth, on the north side of Great Race.

Scott Wallace: Research on Abalone in BC Reserves.

Posted on by

Scott Wallace did research in 1997 and 1998 at Race Rocks with Pearson College divers. He studied the population dynamics of the Northern Abalone,Haliotis kamtchatkana. His research was done as part of a PhD thesis in Resource Management from the University of British Columbia in Vancouver.

Wallace, Scott, S. 1999, Evaluating the Effects of Three Forms of Marine Reserve on Northern Abalone Populations in British Columbia, Canada.

graphsizedistribConservation Biology, Vol 13 No 4, August, 1999, pages 882-887.

ABSTRACT: :Marine reserves have been suggested as tools for assisting the management of fisheries by protecting vulnerable marine species from overexploitation. Although there is a theoretical basis for believing that marine reserves may serve as management tools, there are few marine reserves in the world in which to test their effectiveness. My research evaluated three forms of marine reserve on the south coast of Vancouver Island, British Columbia, Canada. I used northern abalone (Haliotis kamtschatkana), a severely depleted shellfish in this region, as an indicator of the effectiveness of the reserves. Abalone populations in eight sites receiving different degrees of spatial protection were counted and measured in situ during the spring of 1996 and 1997. In all sites with enforced harvest closures, populations of abalone were greater, and one site with nearly 40 years of protection had on average much larger (older) abalone. Reproductive output, as a function of abundance and size, was also greater in the enforced reserve areas. Larval dispersal from reserves, and hence the benefit to exploited areas, was not formally surveyed. Nevertheless, the results of my study, combined with knowledge of present abalone populations, life history, and regional hydrodynamics, suggest that establishment of reserves is justified in the absence of perfect knowledge of larval dispersal.

Underwater Safari- October 1992

Posted on by

In October of 1992, the diving students of Pearson College were able to help with the underwater filming for the Canadian Underwater Safari production. This series of 24 one hour television programs was broadcast live to schools and museum audiences across Canada and the US on the Anik E2 Satellite. Since that time the programs have been broadcast across the world. We have made available at this location some of the unique underwater footage which was taken by the photographer Darryl Bainbridge. The project was an experiment in using technology along with many volunteer hours to help to bring the fragile ecology of this unique area to the world. Our thanks to B.C.Parks for the intial funding to launch the production. The Royal B.C. Museum and its staff , Shaw Cable, BC Systems, BC Tel and many volunteers who provided assistance with this project.

 This video is of Pearson College student Jason Reid ( PC yr. 18) discovering a wolf eel Anarrhichthys ocellatus while the program was broadcasting live. Cameraman Darryl Bainbridge followed the huge fish for some time and caught it feeding on a green sea urchin.

Living on a shelf off the North side of Great Rocks is a Wolf Eel often seen by divers. This very gentle fish cooperated with us for one session allowing some very interesting poses. On this dive, Jason Reid (LBPC year 18) encounters the wolf eel
