Weather for July 14:
Wind: W 15 to 30 knots
Visibility: 15 NM
Sky: Partly Cloudy
Sea: rippled in morning, up to 3′ chop in afternoon
Air temperature: 11-13 C

Weather for July 15:
Wind: W 12 to 35 knots
Visibility: <1 to 10 NM
Sky: Fog for most of the day, with some patches of Partly Cloudy in afternoon
Sea: rippled in morning, up to 4′ chop in afternoon

Wind: W 19 to 38 knots
Visibility: 10-15 NM
Sky: Partly Cloudy
Sea: 2′ chop in morning, up to 4′ chop in afternoon
Air temperature: 11-17 C

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.

Fourth Elephant Seal Pup

Posted on by

Wind: yesterday 1-21 knots varying directions mostly N, today 0-24 knots swinging around N to N
Sea State: yesterday rippled, today up to 2 m swell
Visibility: 10-15 NM
Sky: both days mixture of sun, clouds and rain
Temperature: yesterday 7 to 9 °C, today 8 to 9 °C
Atmospheric CO2: 413.25 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The elephant seal harem has a new addition. In the early afternoon yesterday, another pup was born. Since December 29, there have been four births, which is a record for an elephant seal pupping season on Race Rocks. Unfortunately, only about half of pups tend to survive, due to aggression from other elephant seals, learning to nurse, weaning and predation.

There were three visitors yesterday to do some maintenance on the desalinator: Greg, Warren and Cole. Warren and Cole got a once in lifetime opportunity to see the elephant seal birth. They were walking from the desalinator building to the main house, when Warren noticed the pregnant seal had more flippers than usual. Within less than a minute, the female slid up a grassy incline and out popped the pup. It seems like she used gravity to her advantage. All the humans went into the house, so as not to disturb the seals. The new mother vocalized with the pup and the pup wriggled around. The pup appeared larger than the other three at birth. Perhaps it is a male, as male pups tend to be larger than female pups.

What followed next was difficult to watch. Just ten minutes after the pup was born, it was attacked by another mother. The elephant seal mother that gave birth to the third pup, tossed around and bit the new pup, drawing blood between the eyes and on the head. After a few attacks and several minutes passing, the new mother appeared to intervene and put itself between the aggressive seal and her pup. The mother that gave birth to the second pup also appeared to intervene, by approaching and also putting itself in the middle. Out of the five adults in the harem, the third mother was the only one that showed aggression towards the new pup.

Today, Alex and Greg visited for a couple hours in the middle of the day to problem solve a power issue that presented itself yesterday. It’s great to have a lot of people on land supporting the various off grid systems on Race Rocks.

Here are a few photos from the past two days of the flora and fauna on Race Rocks:

Another Elephant Seal Birth

Posted on by

Wind: yesterday 2-19 knots NE, today 1-46 knots NE shifting to W
Sea State: yesterday 3 m waves from NE, today 2 m waves from W
Visibility: 10 NM
Sky: both days overcast with patches of sun and rain
Temperature: 6-8 °C
Atmospheric CO2: 413.54 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday morning in the rain, I started pressure washing the slime covered stairs up to the door of the lighthouse. They were getting a bit treacherous on a wet and windy day. A second tank of water later, it was sunny and the 18 stairs as well as entryway were clean.

The past two nights have been louder than usual, with the elephant seal bellows and barks dominating the soundscape of waves, wind and sea lion barks. I was surprised to not see a new pup yesterday morning, after all the carrying on outside my windows all night. This morning, the light brought a delightful sight of a new pup. Once again, the eagles, black turnstones and gulls all made quick work of getting rid of the placenta and umbilical cord. The new mother had arrived at Race Rocks on January 3. The other pup looks huge compared the new pup. It’s amazing how much weight the older pup has gained in two weeks. The three females appeared to be at odds with each other for most of the day, with lots of bellowing and chomping. If the remaining pregnant female sticks to the pattern, she should give birth on Tuesday, which is nine days after she arrived on the island.

See the photos and videos below for some sights and sounds of the past two days.
