Elephant Seals: up close and personal video

Mike Robinson took this video of Misery today:

 

Get up close and personal with a Northern Elephant Seal at Race Rocks Ecological Reserve. Lots of facts and personal observations of these magnificent marine mammals, the second largest carnivore on the planet after their Southern cousins.

 

 

David Attenborough did this in depth video of Elephant Seals  from Elephant Seals /Life in the Freezer/ BBC earth

 

Also this video  Elephant sealls of Piedras Blacas , California by Brian Caserio iis very informative.

 

Pelican and Elephants Seals

The big adult male elephant seal (Mirounga angustirostris) is back from a few days excursion. Misery is looking sleek and healthy. The small female looks to be improving. The redness of her wounded eye is diminishing.

Yesterday evening before the gale began a large adult brown pelican was noticed in front of the student house, but it is gone this morning.

Profile : Trev and Flo Anderson Connections with Pearson College 1976-1982

redtower-1When Trev and Flo Anderson arrived at Race Rocks with their family in 1966, the old generator building was painted red and had a tall tower attached for the foghorn. By the mid-1970’s when we started coming out from Pearson College, the buildings were painted white. In 1978, the last of the wooden structures of the generator room were torn down and the present square block concrete building was erected.


lamp76-1“When I first went over to Race Rocks in 1976, the light was made up of four 1000 watt bulbs, with one in the top position on at all times. When the bulb burnt out, it would automatically change positions with a new bulb. The light floated on a platform on a bath of mercury to reduce friction. Years later, Trev wonders how many light keepers were affected by the vapors given off from such mercury sources. In 1978, a beacon was installed that relied on more sophisticated electronics to send out a powerful beam . It wasn’t until after the Andersons left the station that the basin of mercury was replaced with a newer design with 8 beams. ( see lights file)

38Link for this  profile of Flo Anderson:

Flo Anderson was born in Victoria, B.C. She and her husband Trevor and their four children lived at five different B.C. lighthouse stations from 1961 to 1982. In December of 1961, her family left Vancouver to start life anew at the light station on Lennard Island, near Tofino. There wasn't a furnace. She used an old wood stove for heat and cooking, collecting driftwood for burning. She didn't meet anyone else on the island for weeks. "Writing about Lennard Island was very painful for me," she told interviewer Marianne Scott, "Life was traumatic. I was so naive. Recounting it all was therapy. Lots of people have this romantic view of living at a lighthouse. That's why I wrote about it." In 1963, Trevor Anderson became senior keeper at Barrett Rock, seven miles beyond Prince Rupert. Four months later they were sent to McInnes Island in Millbanke Sound, between Prince Rupert and Vancouver Island. Fourteen months later, they were relocated to northernmost staffed lighthouse in Canada, Green Island. In July of 1966 they were transferred to the southernmost point on the Canadian Pacific, Race Rocks, where they spent 16 years. As of 1974, they spent seven years building a yacht in whatever spare time they could find. "All the wives were part-time lighthouse keepers," she has recalled. "Unpaid, of course. It was just expected. When the man was away, the wife filled the gap." Trevor Anderson took early retirement in 1982, the year they launched their 44-foot wooden ketch, WaWa the Wayward Goose, circumnavigating Vancouver Island in 1983. For thirteen years they lived about their boat, once sailing as far as the South Pacific and New Zealand. Flo and Trevor Anderson came ashore in 1995 and now live in Sidney, B.C. At age 70 she wrote Lighthouse Chronicles: Twenty Years on the B.C. Lights (Harbour Publishing), published in 1988.

Igftrevandflo050811t was in 1978 that Trev and Flo Anderson started encouraging students and faculty from Pearson College to seek some kind of protection for underwater Race Rocks. The result was the creation of the Race Rocks Ecological reserve. 33 years later, on August 5, 2011, now retired and living in Victoria, they returned to see the results of the efforts.
Adam Harding’s comment in the daily log tells about it.
“Trevor and Flo Anderson, lightkeepers at Race Rocks from July 28, 1966 until March 2, 1982 had a very pleasant visit at Race Rocks today. Trev and Flo provided endless stories of their 16 years here and certainly provided some historical tidbits for our benefit. Many, many things have changed on the Island since the Anderson’s time. Garry accompanied while Erik drove the boat.”

In 2014 Trev and Flo celebrated their 70th wedding anniversary. At that time they still lived in Victoria BC.

Flo Anderson passed away in 1997..https://www.racerocks.ca/flo-anderson-in-memoriam/ 

Trev celebrated his 100th birthday on October 22 , 2020

Trev had indicated that he had donated several artifacts from Race Rocks to the BC Maritime museum so we went in search of those items on May 22, 2014:

Solaster endeca: Northern Sun star

One of the frames from the video on predation on the Psolus chitinoides

 

Predation of a Psolus chitinoides by a sea star is examined and discussed by Laura and Nadege. The stomach of the sea star surrounds the sea cucumber and the soft neck and mouth of Psolus is well inside the cavity of the sea

We see these occasionally at Race Rocks in the subtidal areas.Their favorite prey are various species of sea cucumber. Their puffy arms distinguish them from other orange stars. They can grow to 40 cm. across.

Entangled Sea Lion gets rescued at Race Rocks

The rope had his right flipper ensnared, and it was caught on a rock leaving him tethered on the island

On December 13, 2009, Ecoguardian Ryan Murphy reported to DFO that a sea lion on Middle Island was entangled in ropes. (See Ryan’s comments below) The ropes were snagged so it could not leave the rock. A rescue was mounted by DFO and the Marine Mammal Rescue Centre of the Vancouver Aquarium on December 16. This was the first time a sea lion had been successfully released from such an entanglement.

Further comments from resident marine scientist and ecoguardian at Race Rocks Ryan Murphy
: December 21 2009
Ryan was interviewed for this article in the Goldstream Gazette: Daring Sealion Rescue at Race Rocks“Normally, neither DFO or the Vancouver Aquarium will intervene with entangled pinnipeds (seals and sea lions), but this case was special for a number of reasons.
1.  The sea lion was actually tethered to the rocks.  These animals are really tough and can often survive for years with their entanglements.  If tranquilized, these animals would take to the water and most likely drown before a rescue team could get to it.  This wasn’t the case here and so a rescue operation was a viable option.
2.  Steller sea lions (Eumetopias jubatus) like this one are listed as a species of special concern under SARA and as such are afforded a higher priority than other more abundant species like harbour seals and california sea lions.
3.  This animal was most likely spotted within 24 hours of its entanglement and was still in relatively good health.  Mike Demarchi of LGL who was on the island monitoring DND activity on nearby Bentinck Island and Rocky Point first spotted it on the morning of the 13th and his team and I were able to keep a very close eye on it during the daylight hours.  It was reported to DFO’s Observe, Record, Report (ORR) line (1-800-465-4336) and the Vancouver Aquarium Marine Mammal Rehabilitation Centre (at 604-258-SEAL (7325) or via the emergency phone at 604-862-1647).  A case like this on an offshore haul out would most likely have resulted in death by starvation, hypothermia, or drowning long before it was sighted.  In the 3 days between the first sighting (first photograph) and its successful rescue, this animal had further tangled its tether from about 10m to 3m and exacerbated the wound to its flipper.  The gale yesterday would have drowned it had it not been rescued.”

 

Puget Sound Partnership-Pearson College Participates

On February 8-11th, 2009, Ryan Murphy, Race Rocks Ecoguardian and resident marine scientist, attended with students Adam Harding and Radu Macovei, the Puget Sound, Georgia Basin Ecosystem Conference in Seattle– Our thanks to Conference Co-Chair Chris Townsend for inviting Lester Pearson College to participate. The following is an excerpt from the conference website.See the Proceedings of the Conference: http://depts.washington.edu/uwconf/psgb/proceedings/table_of_contents.html

“The biennial Puget Sound Georgia Basin Ecosystem Conference is the largest, most comprehensive scientific research and policy conference in the Salish Sea region. The 2009 conference, hosted by the Puget Sound Partnership and Environment Canada, built upon the experience of previous conferences by connecting scientific research and management techniques to priorities for meaningful action. The 2009 conference theme was The Future of the Salish Sea: A Call to Action. Since 2003, the conference has moved from chronicling science research to exploring the science/policy interface. The 2009 conference theme captured this progression from sound science to informed action. Conference participants had the opportunity to apply shared knowledge by developing priorities and a commitment to post-conference engagement.
Conference sub-themes included:
Air Quality & Climate Change
Ecosystem Management Strategies and Techniques
Habitat, Land Use, and Species
Marine & Freshwater Resources “

Slash and Sleep Apnea

Slash the elephant seal male  was having a good sleep in the morning behind the boathouse.

I took this video clip of our resident elephant seal “Slash” asleep in one of his favourite spots behind the boathouse at Race Rocks. At 8:00 am he was in a deep sleep, interrupted only by the kelp flies on his face and a few itchy spots on his body. What was remarkable was the recurring pattern of breath holding. I made this video as a study of this aspect of what appears to be intentional sleep apnea. Since the filming was uninterrupted, one can time the various phases of a breathing cycle. Labels on the video point out the beginning and end of one such breath-holding cycle. I observed that he repeated a similar pattern for at least 15 minutes, the length of time I as was able to observe. GF.

Listen for the sounds and watch for the flaring nostrils.
