Moulting is Itchy Business

Posted on by

Weather and Sea Conditions

After a hesitant start, with locally overcast skies and fog to the southeast, the sun was blazing by afternoon and it stayed that way into the evening. The UV index rose to almost 6 today, which is high. The wind started at 15 to 20 knots from the west, dropped and turned to the south and southeast and then returned to west15 to 20 knots by early evening. The barometric pressure stayed fairly steady between 1005 and 1010 hPa. The forecast calls for the westerly to increase to 15 to 20 early this evening and to 20 to 30 late this evening, then to drop to 5 to 15 knots late overnight. They expect a similar wind pattern tomorrow with more cloud.

Vessel Observations

Seven whale watching vessels were documented working in the protected area today and most followed the rules. One yellow zodiac exited past West Rock heading west, at high speed. Better communication is needed about boundaries, limits and a reminder about keeping at least 100 meters away from marine mammals might be helpful. I know these ecotourism operators want this good thing to last.

Ecological and General Observations

A nice low tide this morning exposed all the beautiful new seaweeds of the season. Bull kelp is growing fast and the Mazzaella splendens is a rich, iridescent burgundy colour. Fresh kelps like Alaria, Laminaria and Cymathere triplicata festoon the rocks in the lower intertidal areas. Up high, the more ephemeral species of nori and sea lettuce are starting to go reproductive and lose their ‘bloom’.

A high density of grazers, keeps the seaweeds in check and feeds the gulls and oystercatchers.

More elephant seals arrived today bringing the number moulting in the garden to eight. On land they are the epitome of lethargic. It is a real treat to watch them in the water, they are so graceful and languid as they chase and roll and spin in slow motion. I also see the River Otter and Sea Otter daily, which is always interesting. The Sea Otter hung out with the Harbour Seals today while they were hauled out on South Rocks. He just floated a couple of metres away as they slept on the rock. He dozed in the water, using the back eddies to stay close. Later he positioned himself in a back eddy that kept him almost stationary, while meters away the current that blasted past at almost six knots. Very savvy sea otter.

There were a lot of shorebirds today, about fifty Surfbirds, a few Rock Sandpipers and a couple of Dunlin. The Black Turnstone numbers are swelling too so I think the migration is happening. The turnstones I watched foraging seemed voracious.

Lantern Fish Found

Weather and Sea Conditions

The day started with a beautiful sunrise and then quickly clouded over, clouds pushed in by light, southeast winds. Late afternoon, the wind veered through southwest to a light westerly.  The barometric pressure, which started at 1017hPa dropped all day and was below 1010 hPa by 19:30.

Light levels were the low today and the accumulated solar radiation for the day was just over 250 Ly, measured in Langleys. That was about half of yesterday’s sunshine. Although it was calm today, the forecast has a gale warning in effect and the west wind is expected to pick up to 35 knots tonight. Monday is expected to be windy, mainly cloudy with a 40 percent chance of showers.

Vessels

Victoria’s first cruise ship of the season, went past last night and today regular whale-watching vessels including Five-Stars and Pacific Explorer were back working in the protected area after an absence of at least a month and maybe more. The more regular visiting catamaran, 4-Ever Wild, cruised through carefully and respectfully. Several sports fishers passed through the reserve slowly, today and all fishing activity observed, was outside of the conservation area. There were many vessels in the vicinity, anchored and fishing for halibut, stretching out from Beechey Head to Constance Bank.

Ecological

Several branded sea lions were photographed and included in the gallery here. The two California Sea Lions were X279 (brand still very pink) and X 10_ , where _ represents a number not yet identified. U390, from the Columbia River region was also photographed. The branded Steller’s Sea Lion noted was 524R a migrant from southern Oregon. Beulah, the large female Northern Elephant Seal was back on Great Race, adorning the lawn at first light and seven other elephant seals can be seen on Middle Rock.

At least 200 Pigeon Guillemots were in and around Great Race in the morning, but gone by early afternoon. The eagles continue to chase gulls on Great Race as well as perching on North Rock, West Rock, South Rock, Middle Rock and Turbine. The geese do not seem to be bothered by the eagles and sometimes land right beside them. There were also over 30 Surfbirds resting here today, even though none were seen during the last census. They were in a mixed flock with Rock Sandpipers and Black Turnstone on the boulder area to the east of the main house.

I found an unusual little (~2.5 cm. long) fish on the marine railway this morning. It was very fresh looking, but dead and undamaged. It looks like a member of the myctophid family.

Also known as a lantern fish, this little myctophid has a typical upturned jaw and rows of fluorescent blue photophores along its abdomen and on its sides. The photophores are packed with bioluminescent bacteria and allow the fish to communicate with light signals in the dark. The eyes are very large (relatively) because these fish are usually in very low, light conditions. Myctophids are very common fish in the ocean, but are not commonly seen, as they usually live deep, in the twilight zone and only come up during their nightly, vertical migration. I am not sure how it ended up on the ramp but currents here could have played a part.

Chores/Visitors

I went off-island briefly this morning and everything worked smoothly. Chores were routine today and there were no visitors.

 

Classic Spring Day

Posted on by

Weather Observations

Today was quintessentially spring. It was already getting light at 05:30 and although there were a few clouds around during the day, it was sunny all day. The UV Index reached almost four, which is rated as moderate. Accumulated solar energy for the day in Langleys was the highest day this week at over 450. (One Langley = 11.62 watt hours per meter2.) Winds were 5 – 20 knots from the west until evening, when they switched to light easterly breezes. There was a significant ocean swell late in the day. The barometer was steady most of the day at ~ 1020 hPA. The marine forecast is calling for light winds becoming easterly 10 to 15 knots early Saturday morning.

Vessel Observations

There were seven visits by whale-watching vessels into the Ecological Reserve. Except for getting too close to the rocks and wildlife, most operators followed the regulations and were careful. The same company that is problematic almost daily has a new larger vessel that sped in the Reserve twice today. The company was notified. Not all vessel operators in this company’s fleet behave badly however the reputation of the company will suffer with a hothead at the helm and so will animals involved in collisions. One speedboat broke down between Great Race and South Rock. The engine cover was off and they were drifting (slowly). I asked them if they were okay and they said they were fine. Soon after, the two-stroke sprung to life in a cloud of fumes and they motored off towards Pedder Bay. An Oak Bay Marine Group vessel followed one of the whale watchers in behind South Rock today and then sped out of the Protected Area. Pedder Bay Marina was advised although they are able to track their boats so can tell where the vessel is and how fast it is going.

Today was animal census day and the results follow.

Student Power

Posted on by

The morning was quiet, overcast and uneventful, weather-wise. Light variable winds continued and the wind did not rise above 15 knots until mid afternoon when the wind became more definitely north by northeast. There is a wind warning in effect calling for south winds of 20 knots near the west entrance to the Strait of Juan de Fuca tonight. The barometer continued yesterday’s gradual fall and reached ~1003 hPa when this log was posted at 18:00. The forecast is calling for a 60% chance of showers with variable light winds becoming southwest 10 to 20 Monday evening.

Only one whale-watching vessel was observed today. They moved slowly and carefully while watching the sea lions and eagles on South Rock. The sea lions didn’t even look up.

Ecologically there was nothing outstanding to report. Spring steadily approaches and will soon be here. There were a few more shorebirds resting, grooming, bathing, feeding and sleeping on Great Race, before the next part of their journeys. Black Oystercatchers are definitely staking out territories in pairs at all the same places that were used last year and the year before. Eagles continue to be busy on all of the islets but particularly Great Race South and West. The sea lions seem truly exhausted and during the day sleep together in huddles with the two species mixed together. One new brand was noted but light levels were too low to verify the number.

Sunlight levels were surprisingly low today. This is good for a low UV index but is not so great in terms of generating solar power. Students Aziz and Sam helped by cleaning most of the solar panels, which helped us capture more of the available energy. Kyle and Keneshka helped move empty propane tanks and other outgoing gear to the end of the jetty for pick-up. Together the four students made a good team and cleaned up the student house after using it for the weekend. Sam also helped launch and retrieve the whaler in time for a test drive to check a couple of things before Chris arrived in Second Nature. That all went well.

Chris arrived for pick-up, with a guest, a naval doctor who seemed to enjoy visiting Race Rocks. He felt very lucky to have grown up beside the sea in Wales. Race Rocks reminded him of larger, more isolated seabird islands that he had visited in Wales.

Malou, a student from Greenland continued her training on Second Nature today and did very well demonstrating her ability. She made a good landing and managed to launch back out into the stream, away from the concrete jetty with no damage, a feat in itself. My limited experience driving Second Nature was that it was a tricky boat to drive, so kudos to Malou.

New Weaner Deceased

Posted on by

Weather

  • Visibility: 15 miles
  • Wind: 0-10 knots North
  • Water: 1′ chop
  • Sky: sunny
  • A fresh fall of snow was visible on the Olympics.

Ecological

  • The first thing I saw this morning was a bald eagle landing over by the Energy Building, right where the elephant seals had been last night, and a place where they normally don’t land.
  • I headed over there and my suspicions were affirmed; the newest weaner had been killed in the night and many birds were feasting on his corpse.
  • Unlike the previous weaner who had simply had his skull crushed by teeth, this one had been virtually torn to shreds, making it much easier for the birds to begin feasting.
  • Chunk was lying nearby, but this time I cannot be sure that he was the culprit, as he didn’t seem to have any blood on him, and Chuckles had been with the weaner last night.
  • The old river otter returned today. It must be blind or in some way sensory impaired, as it is easily approached without seeming to notice ones presence. I say this because I encountered it quite closely by accident, and yet it didn’t seem to take much notice of me until I was only a few feet away.
  • Encountered quite a few surfbirds on the beach.

Maintenance

  • Stacked more firewood.
  • Cleared logs off the ramp.

Boats

  • Two eco-tours came by this afternoon.
  • One fishing boat passed through the reserve.
  • One unidentified boat spent some time floating on the edge of the reserve, but I saw no indication of fishing.

A Stellar Day

Posted on by

Calm seas, sunshine and light winds combined to make it a very pleasant day. The wind really didn’t do much and direction changed throughout the day from west to southeast and back again. There was enough sunshine  to power the solar panels, run the de-salinator  and build up the batteries. The barometer declined slowly all day after a high start and the forecast is for a mix of sun and cloud tomorrow with a strong westerly winds predicted.

Two whale watching boats used the Ecological Reserve today.   From where they were, I am guessing that they enjoyed the pinnipeds and sea otter as well as the birds. Several sports fishing boats transited through at high speed and one fished close to the boundary.

Female Steller’s or Northern Sealion #334R was photographed today. She was branded as a pup in July 2003 at Rogue Reef in  southern Oregon.

Northern or Steller's Sealions hauled out on South Islets, a female born in southern Oregon, branded with #334R is visible.

The Northern Elephant Seals continue to grace Great Race and I am getting used to them not reacting at all to my presence on the walkways.

Four Northern Elephant Seals like peas in a pod, next to the walkway to my house with their tails in the goose exclusion cage.
