Killer Whale # T103 possibly.

Posted on by

The day started with a gorgeous sunrise with lots of golden light pouring under a low violet cloud layer, scattering pinks, reds and oranges. The wind was out of the northeast at 10 – 15 knots and stayed that way until early evening when it turned to west. The barometer continued the climb it started Friday morning, until late in the day when it hit ~1020 hPa and levelled out. The forecast is for east winds and rain.

Six whale watching vessels were noted working in the Ecological Reserve today, one in the morning with a videography crew and five in the afternoon associated with the Killer Whales. Five out of six totally respected the reserve and the regulations.

Although the ER was surrounded by Sunday sports fishers, there was no fishing observed in the ER. One sports fishing charter boat, white ~ 21 – 24’ long, came through Middle channel at high speed, heading towards Victoria.

There were Bigg’s Killer Whales (transients) in the area today and we watched as a large male, possibly T103, made his way from Church Island, through Race Passage and on towards Constance Bank, with a bevy of whale watching boats. Five of those boats also passed through the Ecological Reserve

A branded, male Steller’s Sealion was noted today, hauled out on South Islands. He was branded 603R, as a pup in July 2007, at Rogue Reef in southern Oregon. That makes him 8 years old this summer.

Steller's Sealion # 603R is an eight year old male branded in Oregon, near the California border.

Bald Eagles continue to attack the geese, the Black Oystercatchers continue to gang up on the Raven that may be up to some tricky business with their unsheltered ‘nests’ and the Pigeon Guillemots are spending a lot of time on the jetty and ashore, practicing landing, taking off and walking around. The Glaucous-winged gulls are mating which is quite an acrobatic feat of balance and the Northern Elephant Seal moult is progressing quite fast in the larger animals.

The Day After Blue Planet Day

Posted on by

Winds started out very light from a northerly direction and eventually backed all the way through east, southeast and around to westerlies, 15 to 20 knots and gusting, in the afternoon. Although there were some clouds and showers it seemed to be a nice day, but when you look at cumulative solar radiation values they were less than half of yesterday’s values at just below 300 Langleys. The barometer fell gradually all day and levelled out near dusk ending up at ~100.5 HPa. The strong wind warning remains in effect and is forecast to be strongest in the afternoons for the next few days.

Whale watching boats were back today after the storm subsided and four were observed in the Ecological Reserve. They were meeting and exceeding the Marine Mammal Regulations and although a couple of the smaller cowboys did manage to get between Great Race and South Islands. They were going so slowly and cautiously that the sealions that didn’t even wake up as the boats passed by.

No sports fishers or other vessels were observed in the ER.

All About the Wind.

Posted on by

The west wind blew all night and by daylight, the 30 to 35 knot winds had sucked in low cloud, rain and rough seas from offshore. Winds increased to 35 gusting to 40 knots in the late morning and continued unabated all afternoon. Air temperature was close to yesterday’s sea surface temperature of 9.7 o C and with the wind chill was hovering around 4oC. Light levels were the lowest of the last week and not even 60% of yesterday. The barometer bottomed out just before midnight last night and has been slowly creeping up and out of its hole today. Gale warnings remain in effect for tomorrow with the wind predicted to turn southeast Thursday.

The only thing not affected by the wind today was the stone tower.

There were no whale-watching tour boats in the Ecological Reserve today. Sea conditions were not conducive.

The ecological focus today was to observe how the mega-fauna behaved in the wind. Only a few sealions hauled out, the remainder rested in the water near the haul-out where it was probably quite a bit warmer without the wind chill factor.

This is a day when having blubber really makes sense.

The Northern Elephant Seals made a huddle and “took turns” being in the coveted central, heating position. One female slept off by herself, maybe not quite as warm but definitely more peaceful. Only #5850 went for daily ablutions, the others stayed dry, even if a bit mucky.

Glaucous-winged Gulls hunkered down with heads under wings, keeping a low profile and perhaps holding on with their toenails, as they seemed to totter and grimace during the big gusts. The geese with nests were on them with ganders close by guarding and staying low. The three pairs that are still trying to set up nests were observed chasing gulls . The Bald Eagles, so ubiquitous every other day for the last 25 days, were nowhere to be seen, nor were oystercatchers, turnstones, nor guillemots.

Two marine science classes were supposed to visit today but the weather just didn’t cooperate and Courtney wisely cancelled the trips. Thus there were no visitors and chores were basic routine.

 

 

It is all in the branding

Posted on by

The weather was chilly today but bright, with breezes from the east and west and a few points in between. As the sun sets, brilliant pinks and orange light up the bottom of purple clouds and the wind has picked up to 10 knots from the west. The barometer started a slow climb for the first time since Thursday and the forecast is for a warmer, sunnier day tomorrow.

There were some very persistent sports fishers jigging in the Rockfish Conservation Area today: five men in a fibreglass run-about with an old engine and a kicker.

No tour boats were sighted today.

Another three branded sea lions, two Northern and one Californian were spotted today but only one photograph was good enough to be unequivocal – a Northern (or Steller’s) Sea lion #975R born at Rogue Reef, off southern Oregon in 2011.

Chris in Second Nature, picked up the student group, which was here for the long weekend, just before noon today. It was a treat to have them here as visitors and they even managed to have fun helping with some of the chores. I was a little taken aback by the obvious increase in energy consumption while they were here though, and had to run the generator twice today to keep the batteries up, even though it was fairly sunny all day. Part of that may have been me staying up late to do the blog last night. After I discovered that the genny needed to be run a second time, I went over and turned off several breakers in the science house.

Mount Baker to Bahokas Peak.

Posted on by

It was clear here early and once easterly outflow breezes cleared the American side, it was a beautiful day on the Strait. There was a hazy view all the way to Mt. Baker in the east and out to Bahokas Peak in the west. The barometer is continuing its leisurely dive, started Thursday and as the sunsets, is close to 1003 hPa. The forecast is for more of the same with showers and a chance of thunderstorms.

No tour boats or fishers were noted in the Ecological Reserve today however one boat sped through Middle Channel from the west and then after slowing down went between the South Islands and extremely close to seals and sea lions. Sea lions and seals were on high alert. All of the seals went into the water and some of the sea lions jumped in between the rock and the boat. The boat went back and forth very close to the sea lions several times before speeding off in the direction of Victoria. The whole thing only took a few minutes. The rest of the day made up for it in calm and peacefulness.

Last night as I was saying goodnight to the students who had been helping with chores, there was a definite smell of baleen whale breath in the evening air. I thought it might be the first Humpback Whale of the season. We looked but it was almost dusk and we didn’t see a whale. I heard on the VHF radio today that the whale watching boats had spotted their first Minke Whale of the season, so my guess is that there was a stinky Minke upwind last night.

While doing the seawater sample today, I noticed that there is plenty of big plankton right now. Visible from the jetty are gazillions of beautiful ctenophores or comb jellies. Their scientific name is Pleurobrachia and another common name is sea gooseberry. These jellies are spherical and unlike most jellies they don’t have stinging cells, just sticky cells on their two dangling tentacles, to tangle their prey. They also have eight rows of amazing, tiny paddle-like structures called combs or ctenes. The combs basically do the wave and when they do, it makes a rainbow-like shimmering. So a clear ball, with eight rows of rainbow inducing pulsations and two trailing tentacles; this is a pretty intriguing looking creature.

Ctenophores are important top-down regulators of copepod abundance so they are important ecologically. Copepods are little crustaceans that feed directly on phytoplankton, the photosynthetic kind of plankton. The copepods can be so abundant that at times most of the phytoplankton biomass can be found in their guts. One reason the water is so clear right now may be due to an abundance of copepods. There are also lots of cross-jellies, which are true jellies or cnidarians, meaning they can sting. Their scientific name is Mitrocoma cellularia and they are also predators on smaller animal plankton like copepods. These large plankters are of course also food for baleen whales.

I had a bit of a catch-up day today. I gave the solar panels a thorough scrub and wash, fixed the underwater camera, took photos, cleaned up in front of the boat-house and generally monitored and documented things while tidying up.

A more peaceful sail past ata more respectful and legal distance.

It has been a treat to have students out for the weekend and I think they have been enjoying the peacefulness, nature and each other’s company. I went out to dinner for the first time on the island and we had a delicious meal prepared by the students.

 

Branded Sea Lion Back

Posted on by

Today the weather was like a sandwich, with winter as the bread and spring in the middle. The wind did not relent all day, blowing north by northwest in the morning, with more of a southwest spin, peaking in the afternoon. Now as the sun sets, the wind is easing a little and dramatic rain showers sweep out of the bottom of clouds to the west. The barometer bottomed out late morning and is tentatively climbing now. Tons of new snow on the Olympic Mountains, gives them a magnificent look and brings a chill to the air here only 15 kilometres across the Strait.

I only noted one whale watching boat today but may have missed some while working out of view. Most of the tour boats stop by on the south side to see sea lions hauled out and sleeping in the water there. The photo below was taken a few days ago when the weather was kinder and the animals in the water had just awoken with a start. There were no sports fishers observed in the Ecological Reserve today.

The first thing I noticed this morning was that there were a lot more sea lions hauled out than yesterday (census day). I scanned them with binoculars and noticed right away there was a branded Steller’s or Northern Sea Lion. Even before coffee, which is something for me, I was outside taking photographs. Although the image quality isn’t great due to the distance, it is good enough to match to an individual that was here on September 10, 2014 during my first shift.

This male 533R was branded as a pup in July, 2007 on Rogue Reef. His daytime activity here is practically nil. He lifts his head once and a while to interact with his closely packed neighbours, otherwise he sleeps all day. I wonder if he is full of herring? I also wonder if they forage at night right now?

Sealions hauled out on the south islet. 533R is in the middle of the back row.

Glaucous-winged Gulls seem to sit tight during the day now too. I guess they are establishing nesting territories and resting up for parental duties. They all lift off when a Bald Eagle passes over or a Peregrine Falcon swoops around the island but soon settle back in place waiting patiently.

There are many more Pigeon Guillemots in the Ecological Reserve now than can nest here and they seem to like to forage in fairly large groups, right in the rips and standing waves of the big currents. I would like to see one underwater, using their little alcid wings to fly through the water while steering with their wildly red feet.

Eleven visitors graced the island with their presence today and it was good to interact with people again. Michael who is on the Pearson College board and his family came out with Chris and Alex for a tour. Alex, a student at Pearson College was deckhand and tour guide and did an excellent job of both. Chris solved my water woes by simply turning on a valve that I hadn’t managed to get open.

Chores today included unsuccessful trouble-shooting on cameras #2 and #5, disassembling a bunk bed (probably much easier with two people), and moving the bed frame to the foreshore for pick-up. Seawater sampling, fresh water production and electrical generation, balanced out with more wood clean-up and walkway sweeping. The best thing, was putting up a fresh, new Canadian flag to replace the winter worn one that was fraying badly in the wind.

Sunny, patches of rain the afternoon
Wind: W 4-17 knots, calm in the late evening
Air Temperature: Low 7.7°C, High 10.7°C
Ocean Temperature: 8.9°C

This afternoon, a ring-necked california sea lion was observed on the South Islands. It had something tightly wrapped around its neck, which is digging into the flesh.

While observing the sea lions, a small creature appeared on the edge of the rock ten metres away from them. Much smaller than the sea lions, at about one metre long, it was eating the molluscs in the intertidal zone. To my great excitement, it was a sea otter (enhydra lutris). The sea otter ate, dove, rolled and swam around the South Islands for about two hours.

March 23 – Ships and Sea Lions

Overcast and light rain, sun breaks in the evening
Wind: NE 3-14 knots, switching to W 5-11 in the evening
Air Temperature: Low 7.2°C, High 9.4°C
Ocean Temperature: 8.8°C

Today was filled with the usual chores of cleaning rust of things, collecting wood, stacking firewood, running the generator, creating fresh water with the desalinator, measuring the salinity and temperature of the ocean water and looking out for the species of the ecological reserve.

This afternoon, a large aircraft carrier passed within 4km of the ecological reserve. The USS John C Stennis is a nuclear powered super carrier, the largest type of aircraft carrier, measuring 333mx77m and weighing over 100,000 tonnes.

See the photos below of the ships that passed to the south of Race Rocks, close to where the sea lions swim, hunt and haul out.

Upon looking at the photo of the aircraft carrier, I noticed a sea lion in the foreground that is branded 26Y. This steller sea lion was born at Rogue Reef, Oregon in 2002.

March 19 – Last Day of Winter- Census

Posted on by

Raining
Wind: NE 4-14 knots
Air Temperature: Low 8.8°C, High 10.3°C
Ocean Temperature: 8.8°C

The wet conditions were helpful with cleaning some exterior walls and windows. The rain water cistern was filled up from the roof. The rain also helped wash away the algae and slime on the walls, along with some scrubbing.

The low light and rain made the census difficult. In recent days, there has been a much higher number of harbour seals hauled out on the rocks. The sea lions also spent most of the day in the water. It was not possible to distinguish between the species of cormorants on Turbine or Middle Rock.

There were no boats seen in the reserve today.
