Early Spring Cleaning

Posted on by

Ecological Notes:

  • Still waiting to see if any Elephant Seals show up for the moult season
  • Sea Lion numbers are down a bit and not fluctuating as they have been
  • Transient Orca have been in the reserve 3 times at least over the last few days. they hunted right off the end of the pier, and in the channel just south of the light

Visitors:

  • Shore Front coordinator delivering supplies and fuel

Facility Work:

  • There was water in the basement of the Student and Science Center, and I first I couldn’t find the source. I checked all the plumbing on that side of the room, and mopped up the water. Checked a couple hours later and there was as much water there again. Realize it must be a new leak, and that it was still going. Took longer than it should have to find the leak, as it was working around the lowest points and looked like it was coming from the other direction. Isolated the problem, and repairs will be done tomorrow

  • With warmer weather and less rain, time to start spring cleaning of sidewalks. The algae cleaner needs the temperature, and rain free days to work.
  • Catching back up on fuel deliveries allows the replenishing of the Gerry Cans in reserve.

  • Noticed the fog horn wasn’t working on Sunday during the heavy fog. Coastguard notified so they could put out a notice to mariners. they have scheduled a visit for Thursday to repair it. With current availability of GPS and Radar on vessels, glad I didn’t have to use the manual back up!

  • Checking smoke detectors and first aid supplies that may expired

  • Awaiting new materials for the pier fence, cleaned up old wiring, saving longer pieces for repairs and making gates

DND events:

  • Detonations during the last week, under the guidence supplied by the Marin Mammal Observers on the water.

Noted Vessel Traffic:

  • Still a few Eco-Tourism vessels coming through.
  • 3 or 4 private vessels as well, all appropriate behavior

  • Wednesday January 31:
    • Sky: High overcast with occasional sunny breaks
    • Wind: ESE to 30kts early, rotating through to NE 10-15kts during the day

July 14-16

Posted on by

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
Air temperature: 10-15 C

Weather for July 16:
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.

Smoke And Fog Through The Week

Posted on by

Weather:

  • Sky overcast, heavy fog and some smoke
  • Visibility 1 NM down to 100m
  • Wind 5-15 knots SW
  • Sea state: calm

Visitors/Boats:

  • A contractor came out to do a little work yesterday, and some supplies were brought over as well.
  • We have not had much other activity. Tour vessels are becoming less frequent, and the same for pleasure craft.

Observations: 

  • The fog and smoke cover has been extreme over the past four days or so – it is hard to discern the fog to smoke ratio. The fog horn has been sounding for the better part of those days. Probably an average of 16-18 hours per day and typically going through the night.
  • The sea lions are gradually taking over the shores of Race Rocks! Their numbers increase by the day – the areas around the ‘fuel shed’ and the crane are beginning to see a couple of curious creatures poking around. We’re planning on redesigning the fencing on the jetty for this season and for the rest of the island it looks to be high time for a parameter fence. We do need to keep the buildings protected and significant areas undisturbed, but it has been nice to see the sea lions lounge on the jetty.
  • There seems to be a bit of an increase in some birds. There have been shorebirds and others, perching all around the rock and often resting at night. If we need to move around outside at night we keep an eye out as they sleep in the grass and in the plants around the paths.
  • A census will come hopefully tomorrow – the visibility makes it into a game of opportunity.

Here are some pictures from around the rock over the past couple of days:

Today was spent tidying around the island, chainsawing logs and chopping firewood. I gave the gulls and sea lions a wide berth as I moved around the paths.

650 L of diesel was delivered this afternoon.

Here are a few photos from today:

Three Weaner Elephant Seal Pups

Posted on by

Wind: yesterday 2-15 knots from E to N, today 3-10 knots from S to N to E
Sea State: yesterday and today rippled
Visibility: yesterday and today 15 NM
Sky: yesterday and today clear
Temperature: yesterday 5-7 °C, today 5-8 °C
Atmospheric CO2: 414.73 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The past two days have been sunny, which means the animals and scenery are very photogenic.

There was lots of activity with the elephant seal harem today. Overnight, the third mother left the island, after nursing her pup for 24 days. Her pup is now a weaner, no longer getting milk from her mother. The three mothers whose pups survived all stayed for 24 days. The last female, who’s pup died 17 days ago, left late this morning. After the male mated with her, she was either trying to get away from him or was chased down the path and out into the water by the boat ramp. The alpha male left for about an hour, perhaps to get some food. He’s been on the island the longest of any of the elephant seals. He hasn’t eaten or left the island since before the first pup was born on December 29. That’s almost as long as I’ve been here without leaving, except I eat three meals a day. The female elephant seals will most likely return to Race Rocks exactly eleven months after they left, to give birth to another pup. Stay tuned to the Log next December and January for more pupping season drama.

Now that there are no adult female elephant seals left on Race Rocks, the alpha male’s role has changed from mating with the females, to protecting the three pups that remain. The alpha male is most likely father to all of them, as he was the alpha male last year as well.

Three beta male elephant seals are still on the island. One left for about 24 hours and returned this afternoon. When he slid up the ramp onto the island, he appeared to look around to see if any females were around. Then, he headed for the oldest pup and put his mouth around it. He didn’t appear to be trying to hurt it because no blood was drawn. The pup was screaming. The alpha male came over and scared away the beta male. For the afternoon and evening, the three pups were lying in the grass about 10 m away from each other. It will be interesting to see if the pups interact with each other, as they have in previous years.

Some other interesting sights were a sea otter, two black brant geese, and a very bright Venus visible in the western sky for a few hours after sunset for each of the past three nights.

There were no visitors to the island in the past two days. Four pleasure boats and three tour boats were seen in the ecological reserve.

Coast Guard Visit, The Entangled Sea Lion Is Still Here

Posted on by

Weather: 

  • Sky partly cloudy, intermittent fog
  • Visibility varying between 0-15 miles
  • Wind 20-30 knots W
  • Water rough, waves to half a metre with some whitecaps

Boats/Visitors: 

  • No visitors today
  • The whale watching boats continue to decrease in volume, this month looks to be a turning point in their season.

Ecological: 

  • We spotted the sea lion with plastic around its neck on the jetty last night, and today it was hauled out onto land between the helicopter pad and the guest house. We contacted DFO, and the entanglement response team will assess if it’s a job that they can do.
  • This afternoon we saw a blue heron, which we haven’t seen before out here.

Maintenance:

  • The Coast Guard visited briefly a few days ago. They stayed on RR for about an hour and did some maintenance on the fog horn system. Two people came on to land, and a third stayed in the Coast Guard zodiac.
