Taking Advantage of the Sun

Posted on by

This morning when I looked out the window, I saw a large humpback pectoral fin sticking out of the water. Since, I hadnt seen any humpbacks for a couple days I quickly grabbed the camera! Looking closer, It seemed like the humpback was rolling around and playing with a Sea Lion! They kept at it for almost an hour!

Today was the first fully sunny day in a while, and for a while.. so I decided to take advantage.

I sprayed down as many algae ridden surfaces as I could (Before and After Pics coming soon), and I cleaned the windows on the main house and the student house.

Greg and Rich also came today for a diesel run. We filled the large Tidy tank in the main shed. They also sectioned out some of the logs that had been pulled out over the summer. I will keep chipping away at chopping them so we have more wood for the winter.

Today was a very PNW day… a slow steady rain all day.

I know it gets old quick, but I really love a nice, cozy, rainy day at Race Rocks!

But also because of the rain, most of the sea lions spent the day in the water, making the census counts low.

Of note today, Greg came out to the island, and we fired up the Desalinator after more than an entire year of issue after issue. Greg was jubilant to say the least :).

Maintenance:
When the solar panels were producing a lot of power on July 14 and 15, I used the desalinator to make a total of 700 litres of water. The output of the desalinator is 1.25 L per minute. It takes about 2.6 kW of energy to run the desalinator, on top of the regular 1.2 kW load of the island.

Today I lowered the boat into the water to grease the boat trailer wheels as well as finish installing and testing the new boat GPS and sonar.

Mature Male Elephant Seal

Posted on by

Ecological Notes:

  • A new Adult Male Elephant Seal has been visiting the main ramp area for periods of time. While not quite as large as the Alpha and Beta males here last winter, this guy is pretty big!

  • The Sub-adult Male Elephant Seal, that was hauled out for a week or so last month, has been hauling out on middle rock.

Facility Work:

  • We got the Desalinator up and running! After changing the control panel, we re-checked and adjusted some settings and it’s working fine now.
  • Finished the new layout on the pier electric fence. As we had added a new, more powerful, fence energizer, many of the old wires and connectors were failing. Each Ecoguardian comes to Race Rocks with their own skillsets and ideas. This new idea will hopefully be more  sturdy, and easier to repair and maintain. ……. (but we’ll see!)

  • Received and assembled a new cart for the portable diesel tidytank. As the last one failed, will be adding an additional safety strap to this one for when someone has to move it by themself..

Noted Vessel Traffic:

  • Ecotourism vessels and private vessels have been visiting to enjoy the sights and sounds of Race Rocks.
  • A single paddler in an outrigger canoe also ventured out and through the main channel.

Weather Events:

  • Heavy rains over the weekend gave way to light fog on Monday. Westerly winds of 5 – 10 knots prevailed.

High Winds

Posted on by

Ecological Notes:

  • 1 Male Elephant Seal, and 1 juvenile Female Elephant seal on land.
  • The male doesn’t take notice of where the Gull nests are (of course), so the gulls really harass him if he’s too close! I couldn’t capture a good picture showing the gulls, but this was his reaction!

“Leave me alone!”

  • Steller and California Sealions on middle rock (until DND blasting).

  • Seeing some small migratory birds now, photos and ID’s tomorrow

Facility Work:

  • Second run and close monitoring of the Desalinator, everything work as expected.

DND events:

  • 6 – 8 heavy blasts today. As noted, The sealions all left middle rock at the time of the blasts. Waiting to see if they settle on the southern rocks.

Noted Vessel Traffic:

  • Several Ecotourism vessels and 3 private vessels noted in the reserve sightseeing. All proper procedures followed.

Weather Events:

  • Westerly winds averaging 30 knots all day, rising to 40+ in the evening. Wind against tide brought 1 meter chop, while wind with tide brought chop on top of 1-2 meter swells at times. Mainly clear skies with slight haze to the west and south.

Nature Continues On

Posted on by

Ecological Notes:

  • 1 Male Elephant Seal, and 1 young Female elephant Seal on the island.
  • When they meet on the boat ramp, one of two things normally happen. If the female is above, she holds her ground and makes the male go around. But if the male comes from above, the female will rush down to the water to get out of the way. She barely goes above the 2 lowest buildings (the tank room and the boathouse), even though she was more comfortable up in the grass area when she was here before.

Picture angle is deceiving, the female is much smaller than the male. I would guess 350 Kilos compared to maybe 1600 kilos.

  • After the heatwave that did unfortunately cost some chicks lives, it’s nice to be reminded that life goes on. Fresh eggs hatching, and “families” out going about their business.

Visitors:

  • Waterfront Coordinator delivered groceries, fresh water for the tank, and a new fire pump yesterday.

Facility Work:

  • Fire pump allowed filling the salt water cistern so we could start up the desalinator. It appear to run well and produce nice clean water, but one of the gauges was running very high. We decided to wait and have it checked by the contractor Monday, as we couldn’t solve it over the phone.

Noted Vessel Traffic:

  • Many Eco Tourism boats and private boat touring the reserve. No fishing in the reserve like was prevalent last weekend.

Weather Events:

  • Fog off and on most of the day, leaving light haze in the evening. Westerly winds all day near to 15 knots, calm seas.

Weekly Census

Posted on by

Wind: yesterday 2-16 knots from S to W, today 0-36 knots from W to S to W
Sea State: yesterday rippled, today calm until mid afternoon when seas turned rough
Visibility: yesterday 10-15 NM, today 5-15 NM
Sky: yesterday overcast, today overcast with patches of sun then rain in late afternoon
Temperature: yesterday 7-9 °C, today 6-8 °C
Atmospheric CO2: 413.47 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The numbers of sea lions continues to be low. For the first time this winter, there were more steller than california sea lions in the ecological reserve.

For the past day, the elephant seals have all been stationary. An elephant seal was seen on Middle Rocks today along with california sea lions. I believe it’s the smaller adult male that was on the main island until recently.

Having heard the killdeer on many evenings this winter, but not seen any, I finally saw one this morning on the lawn. They are named for their shrill repetitive call which sounds like “kill-deer!”

Here are the results from the weekly census observed on Friday, February 28:
7 elephant seals (4 adult males, 2 female pups, 1 male pup)
54 steller sea lions
53 california sea lions
86 harbour seals
5 bald eagles (2 adults, 3 juveniles)
26 Canada geese
9 brandt’s cormorants
10 double-crested cormorants
31 pelagic cormorants
72 gulls (mostly thayer’s)
8 black oystercatchers
66 pigeon guillemots
17 harlequin ducks
1 killdeer
15 black turnstones
6 surfbirds
1 fox sparrow

Yesterday, Greg, Alex, Warren and Cole were on the island to do maintenance on the desalinator and batteries. Two tour boats were seen in the ecological reserve each day. This afternoon, the RCM SAR boat from Sooke drove around the main island and the crew took photos.

 

Full Power Restored

Posted on by

Wind: yesterday 0-34 knots from N to W, today 18-36 knots from W
Sea State: yesterday calm in morning changing up to 1m chop, today chop up to 1 m
Visibility: yesterday 5-10 NM, today 10-15NM
Sky: yesterday overcast and rain, today clear changing to rain in evening
Temperature: yesterday 5-8 °C, today 6-7 °C
Atmospheric CO2: 413.81 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

After twenty-five days with backup power, there is now full power on the island. The replacement part for the generator head was installed today. Thanks goes to the team who spent six hours on the island today, hauling the 450 lbs unit from the boat to the generator room, doing the installation and other needed upgrades. It was a busy day here for Greg, Alex, Lawrence, Stephane from Frontier Power, Ric and his apprentice Stephane. Lots of other staff at Pearson College made it possible for this fix and temporary power to be successful.

With full power restored, there is now enough power to more quickly top up the batteries and operate all the equipment on the island without draining the batteries too much. A few important pieces are now running again: the desalinator, Ocean Networks Canada’s CODAR, UVIC’s Davis weather station and both live cameras.

There are still four male elephant seals and three pups on the island. There was some fighting amongst the males last night, evident by the fresh cuts on the backs of three of the males and near the eye of the youngest female pup.

The number of sea lions on the rocks has decreased in the past two days. It could be related to the strong west winds that blow into some of their favourite haul out spots.

There was one tour boat seen in the ecological reserve today.

DND was conducting demolition training on nearby Bentinck Island today.
