Field trip for VNHS

2014-09-27gfvnhstowers

 

Members of the Victoria Natural History Society accompanied ER warden Garry Fletcher on a field trip to Race Rocks this morning. Most of the members were avid birdwatchers so this time of year was ideal to view some of the many species that stopover at Race Rocks in their fall migration. See the census records submitted by Daniel Donnecke

Aequorea victoria, crystal jelly : The Race Rocks Taxonomy

aequorea

Kingdom: Animalia Subkingdom: Eumetazoa Phylum: Cnidaria Subphylum: Medusozoa Class: Hydrozoa Subclass: Leptolinae Order: Leptomedusae Suborder: Conica Family: Aequoreidae Genus: Aequorea Species: A. victoria The following quote  is from Wikipedia.. noted here because of the reference to Dr. Anita Brinckmann-Voss.

“Aequorea victoria, also sometimes called the crystal jelly, is a bioluminescent hydrozoan jellyfish, or hydromedusa, that is found off the west coast of North America. This species is thought to be synonymous with Aequorea aequorea of Osamu Shimomura, the discoverer of green fluorescent protein (GFP). Shimomura together with Martin Chalfie and Roger Y. Tsien were awarded the 2008 Nobel Prize in Chemistry[1] for the discovery and development of this protein as an important biological research tool. Originally the victoria species was supposed to designate the variant found in the Pacific, and the aequorea designation was used for specimens found in the Atlantic and Mediterranean. The species name used in GFP purification was later disputed by M.N. Arai and A. Brinckmann-Voss (1980),[2] who decided to separate them on the basis of 40 specimens collected from around Vancouver Island. Osamu Shimomura notes that this species in general shows great variation: from 1961 to 1988 he collected around 1 million individuals in the waters surrounding the Friday Harbor Laboratories of University of Washington, and in many cases there were pronounced variations in the form of the jellyfish. “

 An interesting account by Claudia Miils about the misidentification of the bioluminescence in Aequorea in various scientific journals and magazines  can be found in Bioluminescence and other factoids about Aequorea, a hydromedusa See this link for other hydroids:  https://www.racerocks.ca/tag/hydroid/

Branded sea lion 183R shows up at Race Rocks

Our viewer from England, Pam Birley,  sent us this image image of a branded Northern Sea lion (Steller’s) that she had taken with the remote control camera 5  today. She noted that this is the first time this particular one has shown up in her records which she has been keeping for several years now.

Visitors to Race Rocks

Today we were able to make a special trip to Race Rocks Ecological reserve with Tensie Whelan with her father Sidney, and Patsy Whelan.

The Whelan’s live in New York and Connecticut and had made a trip to British Columbia to be able to see the place which meant so much to Tensie’s late husband, Johan Ashuvud. Johan had been a student at Race Rocks who in 1979-1980, had worked as a marine science student and a diver leading a group who ended up creating the Race Rocks Ecological Reserve.

Thanks to Chris Blondeau for driving Helen and I and the Whelans out to the reserve.

Friday Night Vessel Scramble in the Strait of Juan de Fuca

This evening as  I write this, 6 cargo ships (bulk carriers and container ships), a ferry and a cruise ship are all underway around Race Rocks Ecological Reserve and out into the Strait of Juan de Fuca. (as viewed on http://ais3.siitech.com/VTSLite/AView.aspx.) The wind is from the West at 50 km/hr. The total length of these outbound vessels if they were placed end to end is 1861 metres (1.861 kilometres or 6,105 feet which is 1.156 miles. )

Trev and Flo Anderson’s 70th Wedding Anniversary

Congratulations from all of Lester Pearson College goes out to the first lightkeepers to welcome us to Race Rocks when the college opened in the 1970s.  They now live in Victoria and are both in their 90’s. Today Helen and Garry Fletcher attended the 70th wedding Anniversary of Trev and Flo Anderson in Victoria. Trev and Flo were the lightkeepers at Race Rocks from 1966-1982.

Ecological Reserves participate in the NEB hearings on Kinder Morgan pipeline.

The Board of the Friends of Ecological Reserves has posted their first set of Information Requests to the National Energy Board and Kinder Morgan as Intervenors in the Trans Mountain Pipeline Expansion Project . Their concerns focus on the Ecological reserves of Southern Vancouver Island such as Race Rocks .

Ships Currently in the Area of Race Rocks, and the Associated Hazards

Shipping in the Strait of Juan de Fuca poses the greatest risk to the ecological integrity of the Race Rocks Ecological reserve. The risk of chronic oil spills increases directly with the Number of vessels in the waters. Chronic oil is a greater risk to marine life around the world than are the disastrous large spills, but the risk from both will increase if tanker traffic is allowed to proliferate in the Strait of Juan de Fuca:

Problems with Marine Vessels and their risk for Race Rocks:

It has always been a concern that Race Rocks is located in a very vulnerable location in the Entrance to the Strait of Juan de Fuca. There is a need for regulations preventing the dumping of bilge and sewage from ships, and an emergency plan in the event of disaster from marine shipping.Shipping  Prshipwreckoblems:
The history of shipping in the past in the area is grim evidence that accidents happen. A fuel or chemical spill in the Strait of Juan de Fuca would have an untold impact on the biodiversity of the Ecological reserve.shipwreckMajor Marine Vessel Casualty Risk and Response Preparedness in British Columbia

Louise Dickson, Times Colonist
Thursday, May 08, 2003
The accidental dumping of raw sewage into Juan de Fuca Strait has renewed calls for stronger environmental regulations governing cruise ships.Norwegian Cruise Lines has confirmed that its ship, Norwegian Sun, dumped about 62,000 litres of raw sewage into American waters near Port Townsend, southeast of Victoria.
Victoria’s Cruise Ship Industry: Economic Benefits and their Environmental ImpactsBy: Elliot Houlston and Carly Daoust , 2005″Being that a cruise ship functions like a small city, it will pollute like a small city as well. In one week’s time a single cruise ships empties 210,000 gallons of sewage (human waste), 1,000,000 gallons of grey water (water from sinks, bathing and washing), 8 tons of solid waste (paper, plastic, cardboard, food waste) and 25,000 gallons of oily bilge water8. Some hazardous wastes such as photo chemicals and used paint are produced also. These are only the water pollutants created by cruise ships. There are many air pollutants as well.”Dirty Waters: Cashing in on Ocean Pollution 18 January 2010 in DC BureauBy David Rosenfeld

We normally see Buffleheads throughout the winter months feeding in bays and along beaches on the shores of Metchosin. The males are much more obvious from their contrasting black and white plumage. This is the first observation we have had in the Race Rocks waters.
