 GARRY FLETCHER

Marine science teacher and Race Rocks champion

BY MARIANNE SCOTT

To visit Garry Fletcher at his home requires a drive through the countryside of south Vancouver Island that seems hundreds of miles from the cities that house most of us. His house in Metchosin, near his son’s organic market farm, looks out over sheep trimming the meadow bordering the Juan de Fuca Strait. An espaliered kiwi vine hugs the deck, nectarine and peach trees provide fresh fruit, rhubarb thrives and herbs enliven meals. Garry grew up on a small Saskatchewan farm; it mixed growing food with raising cattle. Farm life inspired his interest in biology, which he studied at the University of Saskatchewan in Saskatoon. After earning a master’s degree in science curriculum, he taught in Swift Current where he met his wife Helen, who taught English. He was then invited to teach biology at the United Nations International School in New York.“They offer an internationally recognized baccalaureate degree,” he said.“But in 1976, after being mugged in the city, we accepted an offer to come to Pearson College, in Metchosin, thinking we’d be here for, maybe, four years.” But Pearson, its students, curriculum and nautical location ensnared him and he and his family have never left.

PEARSON COLLEGE is a special place. Located on south Vancouver Island’s Pedder Bay, it’s one of 18 United World Colleges and offers a two-year pre-university baccalaureate diploma that covers grade 12 and a gap year for up to 200 students.These students, who represent more than 150 countries, live, study and grow together. Pearson’s mission is to “make education a force to unite people, nations and cultures for peace and a sustainable future.”

At Pearson, Garry began teaching biology, marine science and scuba diving. Jack Matthews, the then College head, gave teachers great freedom to develop their own sphere.“I was able to build an interdisciplinary marine science course that included chemistry, physics and biology,” Garry recalls.“We have this unique situation here at Pearson. Fresh and saltwater, marine ecosystems, forests. I took the class diving, 15 on a boat. We had substantial blocks of time.”

Meeting Trevor and Flo Anderson, lighthouse keepers at Race Rocks, further revolutionized his teaching and interests. Race Rocks, an archipelago of nine jagged islets lying eight miles from Victoria, is the southernmost point of Pacific Canada.The islands are the pinnacles of a large underwater mountain. The lighthouse was the second to operate in BC and was constructed of Scottish granite brought as ballast aboard British sailing ships.The Rocks are named after the passage separating it from Vancouver Island and has a tidal race reaching seven knots. When strong tides and winds oppose each other, standing waves can grow to 10 feet.The upwelling from the currents provides an exceptionally abundant environment for animal and plant life. Some of the islets are favourite perches for Steller and California sea lions, and elephant seals and harbour seals sunbathe here.

“My philosophy of teaching is to instill the concept of ecosystems’ integrity and sustainability,” Garry says.“I explain we’re not on a chain, we’re in a life web. I ask students to  assess their project’s sustainability. Does it have biological integrity? Does it impact the food web or energy flows? What services do ecosystems provide? We must weigh what things will look like in 100 years, not just next year.”

THE LIGHTHOUSE KEEPERS welcomed Garry and students to Race Rocks.“The Andersons knew the uniqueness of the region,”he says.“We dived near the rocks, although with the currents, it could be dangerous. We surveyed and created maps of underwater marine life and collected data on birds and marine wildlife.”

In 1980, this work led to connections with the predecessor to the Ministry of Environment. That ministry managed the “Ecological Reserves” program—areas set aside because of their exceptional natural features, and for their scientific and educational significance. Garry and his students asked the Ministry to add Race Rocks to the list of protected areas.

“Remarkably,”says Garry, grinning,“Prince Charles, the United World Colleges’ chair, came here for a board meeting. We told the ministry the Prince might announce that Race Rocks had become an ecological reserve. Our proposal was approved in record time.”Garry began serving as the Race Rocks Ecological Reserve warden and reported on the Pearson team’s ongoing research. He urges others to propose ecological reserves and has developed an“adopt an ecosystem”template to develop proposals, which can be found online.

MEANWHILE, A MICROWAVE tower delivering live video of island life was built.Two cameras still run today.

Race Rocks Lighthouse was one of the first two built in BC. Race Rocks Lighthouse was one of the first two built in BC. islands are too small for visitors,” says Garry.“So Pearson grad Ken Dunham developed the network that allowed live- streaming internet video—one of the first such projects in North America. During an Apple conference in New York, I was in a boat off Race Rocks live webcasting with a diver filming underwater (Apple later provided access to live streaming on their network). Our students were very hands-on and we delivered other live webcasts of Race Rocks’ intertidal and subtidal zones to schools. It was new and exciting at the time.”

IN THE ‘90S, David Scott (disclosure—my husband) and Ged McLean and grad students from the University of Victoria’s Institute for Integrated Energy Systems took on separate research studies on the feasibility of obtaining electricity from solar, wind and tidal energy at Race Rocks.“These were tests to determine if any of these alternative energy sources were feasible in this natural laboratory,” says Garry.

A BC ministry funded the solar panels and, with an array of batteries, provided the electricity to help power the islands, thereby reducing the diesel needed to run generators. With additional collectors, they still function today. “The 40 solar panels generate enough power in the summer to make the islands energy self-sufficient,” explains Garry. Solar was judged to be more practical than wind and no windmills were built.

THE CLEAN Current Tidal Power Demonstration Project at Race Rocks was the first such project in Canada and the sponsor, EnCana, wanted to assess if the turbine placed in Race Passage could produce electricity during both ebb and flood currents. UVic and Pearson students collaborated on the project.“This was a case study,” says Garry. “Our students dove often to apply coatings that might prevent fouling of the turbine’s blades.”

Alas, the experiment was discontinued after six years. Photos show that giant barnacles and other ocean life had colonized the turbine. “It was just too expensive to maintain,” says Garry.

Pearson continues its protection of Race Rocks. After the federal government destaffed the lighthouse, the College signed a long-term lease and pays for an eco-guardian to provide a constant human presence on the island.

GARRY, now retired, has been recognized for his imaginative and enthusiastic use of technology in the classroom. He’s active in environmental issues. He condemns the doubling of the Trans Mountain Pipeline and has been an intervenor at the National Energy Board hearings. He cultivates and sells mason bees to augment the population of pollinating insects. He’s analyzed the Race Rocks’ water temperature and salinity data collected since 1921.

“Every month, the median temperature is at least one degree Celsius higher than in 1921,” he warns. As a part of a UVic research program, he’s installed malaise traps on his property to help establish baseline data on insect biomass.

Oil cleanup near Island impossible much of the year TC May 2019

I was involved as an intervenor  in the NEB reconsideration Hearings in the fall of 2018. We presented the wind data from Race Rocks which confirms much of the information in this newspaper article. Note Race Rocks is also  mentioned below:

From The Times Colonist -Island Voices: May 26 2017 

Oil cleanup near Island impossible much of the year

If an oil spill occurred in the Juan de Fuca Strait, a cleanup would be impossible or severely limited 198 days of the year, according to Christianne Wilhelmson, executive director of the Georgia Strait Alliance

If you are wondering whether our coast is ready for an oil spill, you might like to know that responding to one at the mouth of the Juan de Fuca Strait, near Port Renfrew, would be impossible or severely limited 198 days of the year.
As part of the National Energy Board’s re-review of the Trans Mountain pipeline expansion, Georgia Strait Alliance examined the physical limits of booms, which are foundational pieces of equipment to contain and deflect spilled oil. We compared their limits to wind, wave and currents along the tanker route, and found that responding to a spill on our coast is likely to result in a significant amount of oil being left in our marine environment.

Most of the booms used to respond to spills along the tanker route are meant for protected water areas, such as harbours. They aren’t built to withstand the currents we find along the route, with 87 per cent of them failing at about 1.5 knots (2.8 km/h). Even the most effective high-current booms on our coast fail at four knots. Meanwhile, in some locations, such as Race Rocks on the southern tip of Vancouver Island, currents can exceed seven knots.
Strong wind and waves carry oil over or under booms, sometimes even breaking them. In the heaviest weather, booms can’t be deployed. Wind and waves surpass boom capabilities for days, sometimes weeks, at a time during the fall and winter at the mouth of the Juan de Fuca Strait. If an oil spill were to happen during one of these periods, our coast would likely be awash in oil.
When the tug Nathan E. Stewart sank in Heiltsuk Nation territory in the northern part of the province in 2016, weather conditions suspended spill cleanup for 11 of 40 days of recovery efforts recovered 1,400 litres of oily water and waste, leaving 110,000 litres of fuel and lubricant in the surrounding waters. The spill contaminated shellfish harvesting areas, forcing the Heiltsuk to halt food and commercial harvests, as well as cultural practices.
Unfortunately, this level of failure is common. The International Tanker Owners Pollution Federation estimates that 10 to 15 per cent of spilled oil is recovered, with the weather limits of spill equipment being a major factor. Spills are complex and difficult to manage — and their repercussions last for decades. We’re 30 years on from the Exxon Valdez disaster in Alaska, which saw the loss of thousands of local jobs and the functional extinction of a pod of orcas, and oil is still being found on beaches in Prince William Sound.
An outcome such as this isn’t one that the people who live and work in the Salish Sea area should have to navigate. The federal government can say no to the expansion of the Trans Mountain pipeline and protect our coast from the risk of a future spill.
The government’s rationale for the pipeline expansion is unravelling: The NEB acknowledges there would be devastating impacts to southern resident orcas; Alberta’s carbon tax and oil-production cap are on the chopping block with the election of Premier Jason Kenney; and oil-spill response is nowhere near being “world-class.” The NEB recommends reviewing nearly every aspect of how we respond to spills — from response resources to the methods we use for spill response to including Indigenous and municipal governments in planning.
The federal government continues to claim that this project is in the national interest, while evidence and research suggest otherwise. The economic case for fossil fuels is unravelling, as the benefits of government revenues and jobs decline, while the impacts of their production on climate change and the natural world continues to climb.
It is time for Prime Minister Justin Trudeau to acknowledge that the government’s case for Trans Mountain is crumbling and move on from this project that puts our coast at risk.

A hub of research activity at Race Rocks today.

A lot of activity was going on today in the reserve.  Guy drove out myself and Laura Verhegge and several others to attend to equipment  at Race Rocks. Already there was a crew with Kevin of Oceans Network Canada who were reinstalling the CODAR sea surface monitor. This was last commented on in a log on  September 28 Also accompanying us was Ed Weibe, of the UVic School of Earth and Ocean Sciences — EOS 110 Labs Vancouver Island School-Based Weather Station Network http://victoriaweather.ca , who monitors the  Davis weather station for our weather page on this site and the UVic Schools  Weather program.  He was there to change the humidity sensor and check on the equipment.  Lucinda Leonard was along to take down the GPS earthquake monitoring equipment after its successful deployment for the past week.  (See the May 10 log)

 

The other activity going on was the installation of a CODAR  monitor by the crew with Kevin from Oceans Network Canada.

GPS Survey for Earthquake Hazard Assessment on Southern Vancouver Island

I accompanied Lucinda Leonard and two students from UVIc  Megan Caston and Yijie Zhu – they are both working towards Masters degrees in Geophysics, working on earthquakes and faults to Race Rocks along with 6 students from Pearson College for the installation of two GPS stations. Many years ago , perhaps as early as 1991, this plug had been installed a meter in front of the Camera 5 location , and it had not been rechecked since.  Laas was able to get this picture of it to verify that it was still there .

GPS Survey for Earthquake Hazard Assessment on Southern Vancouver Island

Participants: Lucinda Leonard, Assistant Professor, School of Earth and Ocean Sciences, University of Victoria
Julie Elliott, Assistant Professor, Purdue University
Yan Jiang, Research Scientist, Natural Resources Canada, and Adjunct Professor, University of Victoria 2-3 students will also take part in the fieldwork.

Objectives:

(1) To quantify seismic hazard of crustal faults on southern Vancouver Island. (2) To improve understanding of crustal deformation in subduction zone forearcs.

Scope of fieldwork:

The research project will establish and survey a relatively dense network of high-precision Global Positioning System (GPS) sites across fault zones on southeastern Vancouver Island that may host significant earthquakes. The 2018 survey will involve temporary instrument deployments at a number of pre-existing survey markers as well as new markers emplaced in bedrock. We anticipate future deployments every 1-2 years over the next 5-10 years.

Rationale:

Southeastern Vancouver Island is a region of high seismic hazard due to its location above the Cascadia subduction zone – the region is susceptible to damage from: earthquakes on the Cascadia megathrust fault offshore (magnitude ~9; similar to the devastating 2011 tsunamigenic Japan earthquake), deep earthquakes beneath the Salish Sea and Puget Sound (up to magnitude ~7; e.g., 2001 earthquake in Nisqually, Washington, that caused minor damage in Victoria), and earthquakes on poorly-understood shallow crustal faults (up to magnitude ~7.5; similar to the 2011 damaging earthquake in Christchurch, New Zealand). Crustal earthquakes, although smaller in magnitude than megathrust events, may produce strong shaking in urban areas due to their shallow source and possible close proximity. Modelling of a scenario crustal earthquake beneath the City of Victoria estimates extensive damage to 64% of building stock, 75% of the water pipeline system, and 90% of the sewer pipeline system in the city (VC Structural Dynamics Ltd., 2016).

Crustal faults remain poorly understood in the region, although recent progress includes the identification of surface-rupturing Holocene earthquakes on the Leech River fault (Morell et al., 2017) and its likely offshore equivalent, the Devil’s Mountain fault (Barrie and Greene, 2018). Fault mapping and trenching are important to determine the maximum magnitude of past and future earthquakes on individual fault strands, but these methods cannot provide accurate estimates of slip rates on fault zones, as required for input into seismic hazard assessments. GPS surveying can be used to track the relative motion of survey markers over time; a sufficiently dense GPS network can be further used to identify the location of active faults and to quantify their slip rates (e.g., Marechal et al., 2015). The existing network of continuous GPS stations on southeastern Vancouver Island is inadequate for this purpose, e.g., there are only three stations within 20 km of the active Leech River fault zone. Campaign-style deployments, repeated every 1-2 years over a time-span of 5-10 years, will provide the greater density of survey locations needed to assess strain build-up on fault zones. Several sites were established in 1991 and re-surveyed in 1996 (Henton, 2000; Mazzotti et al. 2003) – we propose to re-occupy these sites, where possible, and to establish a denser network of campaign GPS sites for temporary deployments (2-4 days at each site).

Methodology
Site locations:
Site requirements: accurate GPS positioning (to within 1 mm) requires the GPS antenna to have a good view of the sky in order to maximize the satellite signals received. It also requires a marker to be emplaced in a stable substrate, ideally bedrock. Thus bedrock hilltops provide optimum site locations. In this region, many optimal locations are located within parks.

Proposed deployments include 5 pre-existing sites, in addition to ~16 new sites, at an average of ~3 km spacing perpendicular to the Leech River fault zone and adjacent faults offshore (Figure 1; Table 1). The greater number of sites to the north of the fault zone reflects greater accessibility over a larger land area in this region.

Figure 1. Proposed locations of campaign GPS sites. Also shown are the locations of continuous GPS sites, pre-existing campaign GPS sites, and mapped faults.

Table 1. Locations of existing and proposed GPS campaign sites available by contacting the research proponenet

For a continuous period of 2-4 days at each site (maximum of once per year), a 1.7-m high mast with GPS antenna will be set up over an existing or new marker in the bedrock at each site, attached by cable to a receiver in a locked box on the ground. During deployment, the mast will be secured to the anchors using chains (Fig. 2a). At sites not conducive to the mast set-up, a tripod (Fig. 2b) or spike mount (Fig. 2c) will be used instead. New sites will be established by using epoxy to fix stainless steel marker pins into the bedrock. These will penetrate 6 inches into the rock, with a diameter of 0.5 inches, to lie flush with the ground surface. For mast sites, three stainless steel anchor bolts will also be bolted into the rock to a depth of ~2 inches, each attached to a 2-inch diameter stainless steel ring flush to the ground, at a distance of ~0.5 m from the central marker.

Approximate schedule for 2018 fieldwork:

The fieldwork will be carried out in August 2018, with each site being surveyed for 2-4 days. The proposed schedule is shown in Table 2 below, although actual dates may differ.

Plans for on-site security, site control and general safety?

The deployment of passive GPS equipment poses little risk to the public. Flagging will be placed on the equipment to mitigate any potential tripping hazards. Signs will be posted at all sites, with the following text (correct dates to be inserted): “Surveying for earthquake hazard study in progress from August 3-6 – please do not disturb. For more information, please contact Lucinda Leonard, School of Earth and Ocean Sciences, University of Victoria: 778-676-9621 or lleonard@uvic.ca”. At locations that are popular with the public, sites will be manned during daylight hours. Sites that see less pedestrian traffic will be visited 1-2 times per day during the deployment.

Data processing and analysis:

Geodetic data will be processed using standard routines to determine precise daily average locations for each site. Positional time series will be analyzed to provide site motions (direction and rate of motion) in a North America reference frame. Analysis of relative motion between sites will enable determination of strain across fault zones and improve seismic hazard assessment for southern Vancouver Island.

Polygonum aviculare: prostrate knotweed – The Race Rocks Taxonomy

knotweed

Polygonum aviculare

I noticed a particularly thriving population of the invasive prostrate knotweed this spring . It is typically successful in heavily compacted areas and adjacent to the sidewalks. Also it is probably not  favoured by Canada geese, as with most of the successful invasive species on the island.

Matricaria discoidea : pineapple weed, The Race Rocks taxonomy

The observation below was made in 2013/06/05 …

Several large areas where the grass was matted and smothered by the sealions hauling out last fall, now have a prolific growth of this newly arrived plant, Matricaria discoidea, or pineappleweed. These are the tallest growing samples of that plant I have seen. Another plant in the same areas is the fiddleneck, Amsinckia menziesii

This year the same situation appears in the areas trampled by the sealions last fall. This post  shows how comfortable it is for the elephant seals.
