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.

 

See Otter

Posted on by

Last night the westerly rose to 40 knots with stronger gusts, after dark. In the morning, it settled to a steady 25 to 30 knots and maintained that early evening when it rose again. The west wind and sunshine dominated the weather here today. The barometer stayed high between 1017 and 1019 hPa until early evening when it started to fall. There is a strong wind warning in effect and westerlies of 20 to 30 knots are expected to diminish to west 5 to 15 late overnight then become light near noon Sunday. The UV index climbed over 4 (moderate) today and should drop with cloud cover and showers predicted for tomorrow.

There were no whale watching or sports fishing vessels observed in the protected area today. The blustery winds and choppy, rough seas were a deterrent and there were whales elsewhere. A tug called Service X, about 35 – 40 feet long, was observed travelling west through Race Passage. It was plunging and taking waves over the wheelhouse as it made headway towards the west coast. One float plane flying fairly low at ~250 to  300′ passed over the island from west to east.

In the Ecological Reserve many of the animals were seeking shelter from the winds. A lone male, Sea Otter came close enough to be photographed and he appears to be in fine form. It may the same individual who was here for the last couple of years. He was seen once in the early morning about a week ago and then yesterday during the census, I spotted him drifting near the few, old Bull Kelp that survived the winter near Turbine Rock.

The eagles continue to chase the gulls and keep them flighty. I didn’t get a good count, but estimated early in the day that there were at least, twice the numbers of gulls counted in yesterday’s census. I will try to get a high count at some point during the week. Two of the juvenile eagles were also observed battling several times today, knocking each other out of the air and tussling on the ground. Chasing off geese is starting to be a losing effort. There are at least two nests now.

Chores were focussed on cleaning and the ever constant battle of the fly today. There were no visitors.

Eagles Use Foghorn Daily

Posted on by

 

The morning started with either low cloud or high cloud. The sun shone under the fog on the Victoria side and on the Sooke side it thickened and the ceiling lowered to become more fog-like. Port Angeles was obscured early. The fog lifted from east to west and resulted in a beautiful clear day with a west wind of 20 – 25 knots, constant throughout the day. Barometric pressure held fairly steady as well, at 1016 -1017 hPa. The marine forecast for the central Strait has a strong wind warning in effect, calling for west winds of 20 to 30 knots and there are showers in forecast.

No whale watching vessels were observed today. One ‘sports’ fishing vessel was observed inside the boundary today but no fishing activity was observed in the protected area.

Second Nature visited briefly with Kyle at the helm and a second person that was supposed to be measuring things.

Today was census day and the results are below. It should be noted that the Bald Eagles were hunting gulls all day on Great Race Island. Although no takes were seen, the gull population thinned significantly during the day and the gull numbers today may not reflect a representative sample of the true numbers seen this week.

Weather Information

It was a beautiful day, calm with lots of sunshine until the fog and fog wind came in from the west in the late afternoon. The westerly rose quickly to 30 knots, gusting to 35 knots as the light faded. There is a gale warning in effect and although it is supposed to come down to 10 – 15 overnight the westerly is expected to rise again late Friday afternoon. The forecast calls for sunny skies with some fog patches. Today the UV Index was just over 4 (moderate) and tomorrow it is expected go higher, to 5 (moderate). Today the barometric pressure went up, from 1016 to 1018 HPa, then back down to 1016 HPa.

Vessel Observations

I picked up Riley this morning in the whaler and then spent most of the day ashore returning in the late afternoon with Alex just before the fog and wind. I was not here most of the day to observe vessels. Second Nature made a visit and delivered 4 barrels of fuel in the morning. On return in the late afternoon, there was one ‘sportsfishing’ vessel trolling in the area closed to fishing. It was enveloped in fog soon after our return.

During the time ashore today, I worked with a group of grade 7 students from the Victoria school district. These students are taking a year-long marine studies program and were very lucky to be able to spend most of today’s school day, studying plankton, marine invertebrates, algae, birds, physical oceanography and marine ecology in the lab and on the foreshore at Pearson College. Thanks to Project Wild, Kelly Nordin and Kathryn Cook, Monterey Middle School parents and Laura Verhegge for making this great learning experience happen.

Ecological Observations

There are still Northern Elephant Seals on Middle Rock and it will be interesting to see how many during tomorrow’s animal census. The Steller’s Sea Lions were sound asleep on South Rock as the fog rolled in late afternoon.

The eagles and gulls continued their deadly game of chase. One goose nest was found with three freshly laid eggs, in front of the student house. This nest is the first of the season.

Solar energy was high and contributed significantly to the island’s power needs, today.

 

Nothing Subdued About a Westerly Gale

Posted on by

The west wind came up sometime after midnight and was already blowing 25 to 30 knots at 04:00 in the morning. The wind rose more with the sun and blew 35 gusting to 40 most of the morning and early afternoon. Late afternoon it dropped to 25 – 30 knots. Although there were showers and some very dramatic looking thunderheads, west wind also tends to bring good weather and the barometer which had taken a dive overnight, spent the day climbing out of its hole. The forecast calls for the wind to drop to light after midnight.

Except for large sea-going vessels, sea conditions around Race Rocks and the central Juan de Fuca Strait area were unsuitable for safe boating. No small vessels were observed in or out of the Ecological Reserve today.

There were eight or nine Bald Eagles here today and as usual the gulls would all lift off when the eagles they passed over the flock. A smaller, more compact bird of prey that flew and behaved like a Peregrine Falcon but had a reddish tail like a Red-tailed Hawk made the gulls extra nervous this evening as the sun was setting. The light was not good enough to get a good look at it except to note that it was an exceptionally agile flyer in the heavy winds and from top view it had reddish, burnt sienna-coloured tail. It would swoop through the vegetated area about a half-meter off of the grass; pick up speed and then wheel up into the flock of gulls. The hawk (?) falcon landed on the rock beside camera five, a vantage point, then peeled off backwards with the wind as an eagle approached. It was almost half the size of the eagle.

It was a day dominated by wind and that is perhaps why the big female Northern Elephant Seal left early this morning. Other pinnipeds continued to haul-out as usual.

Sunshine powered the desalinator again today. The system’s media filter was back-flushed, rinsed and refilled and the 20-micron cartridge filter, replaced with a clean one. Other chores were more routine, such as fighting entropy. There were no visitors.

 

 

 

 

 

A Subdued Day on the Rock

Posted on by

Light northeasterly winds and grey skies made for a subdued day. The barometric pressure dropped a little, from 1020 to 1010 hPa. The forecasters are calling for a westerly gale starting after midnight, with showers and a risk of a thunderstorm.

Five whale-watching vessels were observed working in the protected area today and there were lots of sports fishing boats in the area, not fishing in the Fisheries and Oceans conservation area.

The usual Saturday dive charter was operating in the protected area and had his divers in the water on the ebb tide. They were picked up over by Turbine Rock.

Ecologically, more migrants are passing through each day. More Dunlin were spotted today, all with two legs. There were larger numbers of Black Turnstone and Surfbirds today as well. California Sea Lions are hauling out on Great Race again now, a little too close to the house for a quiet night. Geese are starting to arrive in the middle of the night too and they always do a lot of honking on touch down.

Work was mostly cleaning up and packing for a few days away. If the weather cooperates, I will head home tomorrow and Riley will take over until March 31st. I look forward to reading Riley’s blog.

 

 

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.

83rd Day of Gregorian Calendar

Posted on by

Today was a more dramatic day featuring strong westerlies, 25 -30 with gusts over 35 knot, lashing rain, dark horizon lines and brief periods of brilliant sunshine. The barometric pressure has been rising since the westerly started last night and reached 1019 hPa by early evening. The forecast is for westerly winds of 20 to 30 knots diminishing to westerly 15 to 20 this evening and to light Friday morning. Friday has a sunnier look and the UV index is forecast to be 4 or moderate.

No whale-watching vessels were observed working in the area today and it would have been miserable for those on deck if they had been out in this weather. No boats were seen in the Protected Area today.

Migratory shorebirds continue to take rest, food and shelter on Great Race. Today I had the opportunity to observe two feeding on (?) above the inter-tidal but in a ‘rich’ spot occupied by hundreds of sea lions in the fall. The cormorants and sea lions switched rocks today. I am not sure how the various haul-outs are chosen by the different species but see the changes.

The large, female Northern Elephant Seal (nick-named Beulah) got really energetic this morning and moved about 15 meters. She is now stretched out beside the walkway to the Eco-guardian’s house.

Today was animal census day but the weather was so bad that I am going to do it tomorrow. Harbour Seal haul-outs almost all have breaking waves so few hauled out; very windy and rough.

There wasn’t enough light to run the de-salinator today but there was enough to take a few photos. No visitors today. Chores were routine.

Beulah Rolls Over

Posted on by

Winds were light and variable today under cloudy skies with occasional showers. Tomorrow has a similar forecast, partly cloudy, 40% chance of showers with the strong west wind warning continued. The barometric pressure reached 1020 hPa in the early hours of the morning and then dropped to 1012 by dusk. The wind materialized with rain after dark, gusting over 30 from the west.

Only two whale-watching vessels were seen today and neither was in the reserve. To the northeast of Victoria, J-pod (Resident Killer Whales), a Minke Whale and Transients (Bigg’s Killer Whales) were a draw for the whale watching fleet.  Two sports fishing vessels cruised through slowly.

Nothing to much report ecologically today other than spring is progressing rapidly. The female Northern Elephant Seal (Beulah) made the huge effort of rolling over today. That was it for activity there. Bald Eagles continue to fish and hunt birds in the reserve. The River Otter showed himself again today, near the derrick and within a meter of a small gaggle of geese. The River Otter was busy rubbing his scent gIands all over the grass there and then went into the sea and swam off in the direction of North Rock. From the scat, it looks like a fish diet, lots of scales and medium sized fish bones. I continue efforts to persuade the geese to nest on Vancouver Island. Seals, sea lions and cormorants rest, roost and dry out on the rocks. Glaucous-winged gulls, Black Oystercatchers and Pigeon Guillemots all make preparations for parenthood.

Pearson College divers, under the supervision of Laura Verhegge, visited this afternoon in Second Nature. They did a dive with three groups of divers, during the flood, in the back eddy by the jetty. Some of the students were ‘over the moon’ about their experience and really enjoyed the colours and rich sea life. They wanted to continue exploring even when it was time to go. Others were in ‘a little over their head’ and glad to be back on board. Great leadership and teamwork brought out the best in everyone. A very small sea lion appeared to enjoy having students to investigate and some of the students noticed.

No photos today, sorry, technical problems with camera.
