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.

Wind: yesterday 5-15 knots from N to NE, today 6-36 knots from E to W
Sea State: yesterday rippled, today rippled in the morning and up to 1 m chop beginning late morning
Visibility: yesterday and today between 5-15 NM
Sky: yesterday overcast, today rain in morning and sunny in afternoon
Temperature: yesterday 7-9 °C, today 8-12 °C
Atmospheric CO2: 414.67 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The blasting at nearby Bentinck Island wrapped up this morning, after three days and about 25 blasts. The sea lions left the jetty completely this morning after a few loud blasts. It sounded louder this morning because the northerly wind, coming from the direction of Bentinck Island.

Since the power issues began last week, the Environment Canada weather station at the top of the tower has not been reporting the hourly weather conditions for Race Rocks Lightstation. Replacement communication equipment is being sent out, so hopefully the weather will be recorded again within the next few days.

Two eco tour boats were in the reserve over the past two days. The only visitors to the island were Greg and Alex, a Year 39 Pearson student, who came by yesterday to drop off jerry cans of gas for the back up generator. Alex was reminiscing about visiting Race Rocks and SCUBA diving as a student.

See the photos below for sights from the past two days:

Boats

  • A couple of eco-tours came by.
  • Second Nature came out multiple times, delivering 4 groups of students.
  • On her second last return, she had overheating issues, so Kyle had to come out in Haiku for the last trip.

Visitors

  • Kyle, James, Laura, and 26 students came out to Race Rocks today.
  • The students were doing a walk about with Laura, discussing marine biology for their upcoming final exam.
  • James did some work on the Davis Weather station and got most of it working again.

Other

  • Four DND blasts today.
  • 10:05, 10:07, 11:24, and 11:26.

Highest recorded temperature, Fuel inventory, and Supplies

Weather

  • Visibility: 5 miles, later 15
  • Wind: 5-10 knots, later 25, West
  • Water: rippled
  • Sky: rain and/or sun throughout the day
  • According to the Davis Weather Station, today had the highest recorded temperature at Race Rocks for any February 12th since the station was set up in 2006. Today’s high was 11.6 C, beating last years record of 9.8 C.

Ecological

  • In the morning Chuckles went over to Weaner’s corpse and looked at him, rolled him around, and sat on him. Then he left the island.
  • Chunk came back and rejoined the two females and pup.
  • Middle Rock mum and pup still there.
  • I decided to start calling the new female Lady.

Maintenance

  • Conducted a fuel inventory list for Jeff of Maintenance. Good news: there is more than enough fuel to last until after I leave.
  • Scraped rust off of the two empty 55 gallon diesel barrels and spray painted them to extend their useable life.

Boats

  • Jeff and an assistant came by at about 14:00 to drop off food supplies, a ramp for the diesel tanks, and to have a look at the Davis Weather Station wind reader. Unlike the other day though, the wind reader seemed to be working just fine.
  • One eco-tour boat came by at about 15:00. It seemed to be closer to the sea lions than the guidelines allow.

Too close?

Male Elephant Seals: Island Swap

Weather

  • Visibility: 15 miles
  • Wind: 0-10 knots, at various times from the N, W, S, and E.
  • Water: calm
  • Sky: overcast, then rain, then sunny.

Ecological

  • Chuckles spent the day lying on the grass on the SE corner of Great Race.
  • Chunk attempted to mate with the grieving mother in the morning.
  • After mating, Chunk chased the new female and seemed to wound her slightly, before giving up the chase and going into the water.
  • Chunk spent the rest of the day on Middle Rock with the mother and pup.
  • The newest (fourth) pup is still doing well.

Maintenance

  • Finished stacking firewood under the stairs of the Students’ House.
  • Hauled away many small chunks of wood from near the ramp.
  • Noticed that the wind direction meter seems to be malfunctioning at the Davis Weather Station. Looking into what can be done.

Boats

  • One eco-tour boat passed by at 14:00 heading West, before returning at 15:30. At times it seemed to be closer to the rocks than is permitted.
Closer than the mammal watching guidelines?

March 15 – Raining

Posted on by

Rain (22.6 mm in total)
Wind: 2-9 knots NE in the morning, 4-29 knots NE to WSW in the afternoon/evening
Air Temperature: Low 6.3°C, High 8.9°C
Ocean Temperature: 9.0°C

The students visiting from Pearson were picked up this morning by Chris in Second Nature. They were a great help around the island for the past week as they helped clean and organize. They also pursued their own projects in diving, photography, identifying the flora and fauna, catching up on their studying and locating the mysterious secret room at Race Rocks.

The day was spent doing lots of odd jobs around the island: securing a large log for firewood, cleaning windows, de-algaefying buildings and computer work.

There were a lot of new puddles formed today in the grass and rocks. 22.6 mm of rain was recorded by the Davis weather station, which is located in the middle of Great Race near the flagpole.

A large river otter was spotted this morning scampering up the jetty beach, then underneath the boardwalk by the tank room.

March 4 – Eagle Gathering

Posted on by

Sunny
Wind: 8 knots NNE in the morning, diminishing in the afternoon and switching to W in the evening
Air Temperature: High 9C, Low 4C
Ocean Temperature: 8.8C

Twelve bald eagles were hanging out on the South Islands this morning. Many of them stuck around for the rest of the day, flying to different perches around the reserve.

Chunk left the main island at some point last night. The female elephant seal is still camped out to the east of the main house.

Courtney and Max visited for a couple hours this morning to do some maintenance on the cameras and other technology. Camera 5 is almost online again. One more replacement part needs to be installed in the coming days. The Davis weather station is back up and running after a few days offline. Thanks to Max fixing the computer that uploads the weather data.

There was more munitions blasting today at nearby Rocky Point.

Three eco tour boats visited the reserve today.
