Visitors

Posted on by

The northeast wind blew 25 – 30 knots, all day under mostly clear skies. Most of the day, visibility was excellent with Mount Baker visible to the east and Bahokas Peak to the west. Much closer, the snowy peaks and ridges above the Elwha River were also clear and magnificent. High cloud started forming in the afternoon and sun dogs were visible late in the day. The high cloud eventually thickened and lowered and the sunset was devoid of the usual colour. The barometer dropped slowly all day but remained above 1010 hPa at dark. The forecast calls for more cloud, a 30% chance of showers and lighter east winds.

Four whale watching vessels were observed working in the Protected Area today. The first boat through, looked very small as it clawed its way through the standing waves of Race Passage. I don’t know what chance they would have if anything went wrong in that perilous time and place. All the whale watching vessels went around to see the sea lions on South Rock and one vessel took the passage between Great Race and South Rock. It was good to see S.V. Amatuana out in the Strait with wind in her sails. She stayed well away from the rocks.

A few of the breeding pairs of Glaucous-winged Gulls were observed starting nest building behaviour today and there was more pre-breeding behaviour observed. Oystercatchers also seemed to be staking out territories and spending more time in pairs.

Visitors came today, the first group this month. They arrived in Second Nature skippered by Chris Blondeau. Chris always makes landing look much easier than it is. He brought four Pearson College students to spend the weekend at Race Rocks and six of the Jeane Suavé scholars who have been visiting Pearson College. Chris gave the scholars a tour while the four students settled in. A fifth student came along for the ride and returned to the college with Chris and the scholars

Green with Shades of Blue

March 17 was a windy day on Race Rocks. The early morning east northeast wind  kept intensifying and it was blowing 25 – 30 knots northeast by noon. It kept up for the rest of the day. The barometric pressure started to drop from a high of 1026 hPa, in the afternoon. The forecast includes a gale warning, with the easterlies continuing under sunny skies for at least tomorrow.

One whale-watching vessel was observed working in the Protected Area today and several others were seen transiting the area. Sports-fishing boats were all outside the reserve.

The Nanoose Yarder, a tug, headed west through Race Passage with the fishing vessel, Arctic Fox II in tow. The Arctic Fox II was damaged by fire in Cowichan Bay last winter and looks like she will need some serious TLC before heading out again to troll for tuna, offshore. DND blasting continued.

The impression that the gull population was rising daily, returning en masse was not wrong. Nest site locations from last year are almost fully occupied. Pairs are standing close, pulling vegetation and starting to jockey for position with neighbours. No actual nest building has been observed yet. Canada Geese have been discouraged.

The idea that more California Sea Lions were showing up was backed up by more brands observed today and of course by the counts themselves.  Today was animal census day and results are posted below.

A Quiet Day (Except for the Explosions)

Posted on by

As predicted, winds were light today, starting in the southwest, then switching to west, 5 – 15 knots. Although it was sunny, there was a real nip in the air first thing. The barometric pressure continued its slow rise today, reaching 1025.5 before steadying. Tomorrow’s forecast calls for more sunshine and a low of 2o C, while and winds to switch to east, 20 – 25 knots.

Several whale watching boats visited the Ecological Reserve today, stopping by South Rocks to see the sea lions and eagles. It was a beautiful day to be out on the water. A few sports fishing boats passed close by and fished outside the Protected Area. There were more explosions from across Race Passage today and it was unusual that they continued after dark.

Images of sea lions sleeping on South Rock before and after an explosion can be seen below. Three branded sea lions were photographed today; two California Sea Lions #U68 (brand on posterior) and #8240 (brand on left side) and one Steller’s Sea Lion #42DY.I remember #8240 from last fall but had not noticed him until today during this shift. There appear to be more sea lions daily.Tomorrow is census day. At dawn this morning, Alex noticed a small seal, possibly a Northern Elephant Seal and a Sea Otter on the ramp.

Forage fish were active at the surface again today; guessing that they are herring are on their way back out to offshore habitat after spawning. The fish attract the fishers and by late morning there were three adults and 12 juvenile Bald Eagles in the Protected Area. They favour sitting in large groups on South and West Rocks but they also use Great Race in a more solitary way. The Canada Geese seem to be staying away and the large number of eagles may be deterring them from feeling comfortable on Great Race.

Harlequins continue to astound and inspire with their gorgeous plumage and amazing diving abilities. All three species of cormorant Pelagic, Brandt’s and Double Crested were busy in the Ecological Reserve today. It appears that they like to forage where there are convergences and upwelling. They dry their feathers, roosting in the wind and sun on the west end of Great Race, Turbine and Middle Rocks.

Chores were routine today.

 

Under way on Nuclear Power

There was a large roar made by ocean swells breaking and surging on the west and southwest sides of the island, at first light today. Winds abated and light southwest to west winds in the morning turned to light west in the afternoon rising to 15 to 20 knots by evening. The sky cleared by noon and stayed that way until dusk. The barometric pressure continued Monday’s trajectory, rising above 1022 hPa by mid-afternoon and holding there into the evening.. The marine forecast calls for light winds Wednesday and a few days of sunshine.

Four whale watching vessels were observed working in the Protected Area today. All four vessels went around to the outside (south) of South Rock to observe the seals, sea lions and eagles. One sports fisher was observed travelling through the reserve and dip-netting fish near the Rosedale Reef buoy. Forage fish, possibly herring seemed to be boiling up to the surface their drawing numerous eagles, gulls and cormorants.

An Articulated Tug and Barge (ATB), (barge, a loaded oil tanker), was noted outbound, this morning. When we checked for a vessel name on the Automated Information System (AIS), http://www.marinetraffic.com/en/ais/home/centerx:-124/centery:48/zoom:10 it did not show up on the marine traffic system neither did the tug attached to it as a pusher.

A report to the BC Ministry of Environment on the risk of oil spills in BC waters (http://www.env.gov.bc.ca/main/west-coast-spill-response-study/)states that barges are not required to use AIS however their tugs should register. The report goes on to say that a spill from an ATB could exceed 25,000m3 of oil. Fuel barge movement statistics provided by Canadian Coast Guard Marine Communications Traffic Services to the 2013 BC report show over 1000 fuel barges outbound from Victoria, Vancouver, Comox and Prince Rupert and another 514 transiting Victoria alone. Why are they not required to register? There have been several near-miss incidents with these oil carriers; why not use every means possible to maximize safety and reduce risk, such as AIS?

To put things in context, a show of force was led by the USS Shoup heading out to sea, followed an hour later by a very large submarine escorted by a convoy bristling with military might and expense. The usual explosions from Rocky Point put the ar in arsenal.

Ecologically, the gulls are becoming more abundant and settled in their nesting spots. Territorial disputes are a daily occurrence now as are the calmer moments of pairs just standing together gazing at and grooming each other. The Harlequin Ducks have been busy with all the whitewater activity and take their rest on the boulder beach just southeast of the main house. Pigeon Guillemots were back for a morning visit to Great Race.

Sea lions and Harbour Seals had really good daytime sleeps today recovering from the storms.

Temporary repairs were completed on damaged roofs, as was clean-up and mopping up from the storm.

After the Blow

Posted on by

The west wind dominated today, 10 -15 knots in the morning rising to 25 – 35 in the afternoon. Periods of sunshine were obliterated by purple line squalls with heavy rain. Barometric pressure rose all day and was 1012 hPa at 20:00. The outlook is for west winds 10 – 20, a 70% chance of rain and then clearing and light winds on Wednesday.

Three whale watching vessels were observed working in the Ecological Reserve today. There were two large military explosions and the picket boats were on duty near, but outside the protected area.

The Harbour Seals and Pigeon Guillemots returned in numbers today and the gulls are preparing for spring in spite of low snow on the Olympic Mountains across the strait.

Temporary patches were applied to the derrick house, boathouse and tank shed between squalls. The basement of the science house was mopped out and various window leaks in both houses cleaned up. Other chores were routine.

These two peaks in the Olympic Mountains, just east of the Elwha look a bit like Olympic Lions.

Sea Spray and Flying Foam

Posted on by

Update at 17:40

Since writing the log the wind turned to west, southwest and came up even stronger. We have sustained gusts up to 62.7 knots. Seas are coming over the helipad and the tank-shed and boat shed roofs are being stripped off and are flying past the house. Yikes.

Sustained east, southeast winds of 30 to 40 knots, gusting to over 50, pushed seas up into breaking whitecaps this morning. Large breakers rolled down the jetty and rose up around the derrick base making seawater sampling impossible. Under heavy skies, waves crashed against the eastern face of Great Race and flying sheets of salt spray dominated the small landscape here. There was even a pocket of sea foam building up on the boulder beach and foam was flying right across the island.

Barometric pressure dropped overnight and kept going down in the morning, reaching 982 HPa by early afternoon. The highest gusts were observed late morning 53.4 knots on the Lighthouse system which we can monitor in the kitchen. Gale warnings continue and the forecast is calling for a turn to strong westerlies in the afternoon, diminishing to southwest 15 to 20 overnight. As this log is posted at ~15:00, there is no sign of it letting up and the rain has started.

It was not a day for small vessels to be out and none were seen. Pan pans on the VHF radio included an overturned Junior Flyer with a father and son (a child), clinging to the hull of the overturned vessel. Their call originated in Puget Sound and the US Coast Guard rescued them. What was that man thinking?

There is obviously a great deal of mixing going on in the sea, with all the wind and wave energy churning things. That means spring phytoplankton blooms are still some time away and early herring spawns may produce larvae that go hungry. Stratification (stable layering of the water) becomes possible when less dense surface waters (warmer, less salty, or both), float on top of denser seawater (saltier, colder or both). That layering in surface waters gives some stability for growth of photosynthetic plankton that drive the food chain and rely on light. Light levels are returning, there are lots of nutrients, so as soon as it calms down for a while there should be a plankton ‘bloom’.

On the bottom, microscopic Bull Kelp ‘plants’ are starting to grow now. They will be full size by July after phenomenal  growth fuelled by sunlight and nutrients. A few ‘old growth’ Bull Kelp were visible today, silhouetted through the waves on breaking reefs; for brief seconds as the waves crested, they stretched out fully vertical. Bull Kelp clings with tenuous holdfasts anchored through storms and calm. They are considered to be an annual species and don’t generally last much more than a year so the ones still here are very hardy.

The wild goose chase continued today as if the weather wasn’t enough to ward them off. It was too windy for the eagles and the gulls were hunkered down in nooks and hollows head into the wind in order to stand their ground against the wind. A few of the larger sea lions managed to haul out mid day. It looked too difficult (and dangerous) for the smaller animals that were seen cavorting in the waves. Again there was no sign of seals or guillemots.

Landing would have been impossible today. Even at low tide, big breakers were sweeping the jetty. Chores were routine as wind and spray permitted.

Rest and Recovery: The Lull

Posted on by

Friday and Saturday were both calmer days, with light winds and a mix of cloud and sun. The barometric pressure dropped slowly all day Friday and then wobbled back up today to ~1001 hPa where it holds as this entry is posted at 19:00. There is a warning for central Juan de Fuca Strait, calling for ‘Gale’ force winds of 34 to 47 knots east to southeast. At dusk there were large thunder clouds dropping heavy rain, moving towards Sooke.

With the warning in place and the last storm a fresh memory, there were few small vessels seen on the horizon yesterday and today. Only two vessels were observed within the Ecological Reserve boundaries today. One was a speeding sports-fishing boat heading for Victoria. It passed remarkably close to the small reef that just shows above the surface, west of North Rock. The other was also a sporty boat equipped for salmon and halibut. It passed through Middle Channel very slowly, against the flood.

The Strait was busy with marine traffic including four RoRos, (roll-on, roll-off, car carrying vessels with a capacity of ~6,000 vehicles each), in a steady procession outbound. The cable laying ship was inbound as was the tanker Argent Sunrise amongst many others coming and going.

On Great Race, the Glaucous-winged Gulls are back in force, pairs occupying their favourite spots in shiny new plumage. The gull count today was 340 including ~25% juveniles and an estimated 125 paris of adults. One Western Gull and a few California Gulls were amongst the mix. Every time a bald eagle passes over, all the gulls lift off as though raising their collective hat in respect. The two birds observed killed by eagles, to date, on this shift, were both cormorants. They are not such skilful flyers as the gulls and probably easier to pick off.

Harbour Seals missing in action during the last census; have returned to their haul-outs and today’s count was 97 individuals. The Pigeon Guillemots returned this morning as well (~75) but were all gone by early afternoon.

Remnants of the heritage lighthouse gardens are blooming everywhere right now and the rich green growth is a draw for Canada Geese.

Went ashore yesterday for first time this shift. Picked up Alex and supplies. The visit is timely on many fronts. Chores were much more than routine today and it is really great to have good company.

 

 

 

 

Back to Westerly Gales

Weather-wise, yesterday was wild weather and today dramatic. After yesterday’s log was posted and the internet was out,  the wind turned to southeast and sustaining over 50 knots. The barometer bottomed out at ~987 hPa  in the early hours of the morning and then started to rise again. As today’s entry goes on the web-site ~17:00 it is at 1006 and climbing.

This morning, the sea was still in motion with a substantial swell (~1m) from the southeast that was knocked down later by the flood tide and west wind. The wind switched to west fairly early in the morning and it has been blowing 20 – 30 knots all afternoon. (Oh for a wind turbine that doesn’t harm birds.)

The forecast for Friday is a switch to east overnight, 5 – 15 knots, turning back to west 10 – 15, by late afternoon. Showers to continue.

No vessels were observed in the Ecological Reserve today. Explosions resumed around noon, with the red flags flying a warning to all.

Geese are starting to prefer Rocky Point’s grassy areas and that is a good thing. The high density of eagles here could be unsettling. A Bald Eagle was observed taking a cormorant today. The big adult ate about half of it. Another slightly smaller, adult (male?) approached, waited and they switched off carefully in the wind so the carcass would not fly off. The male (?) ate most of the rest, before taking off with remains in talons, as gulls moved in to clean up. There were a few different species gulls resting here today. The Harbour Seals didn’t show up yesterday or today, nor did the Pigeon Guillemots.

One tagged California Sea Lion was photographed; tag and brand # X79. A necklaced Steller’s Sea Lion was observed and photographed. It look a lot like one that was here last fall except that the plastic on the neck may be coming apart. The animal is vigorous. While under observation, it climbed off one rock, swam across head held high and climbed up another rock, to the top of the ‘dog pile’.

Today was census day and here are the results.

Wild Easterlies

Posted on by

The ferocity of 40-knot easterly winds and heavy seas made for a spectacular storm day. The barometer, deflected by a big low-pressure system (965 hPa) passing by offshore, started to drop at about 08:00 this morning from the overnight high of 1008. As this piece was posted at 17:00, the pressure is 994 hPa and still falling.

A gale warning is in effect and the Environment Canada marine forecast calls for winds to veer to the south 25 to 35 tonight. The wind is supposed to drop to southwest 15 to 25 knots by Thursday morning and to light by evening. Although there was a brief period without rain in the morning, sea spray and rain mixed in the afternoon. Rain is forecast on and off for the rest of the week.

Not surprising, there were no vessels seen in or around the Ecological Reserve today. The neighbourhood explosions continued mid-day and I did not envy those standing by in the two little boats, on watch, as the winds and sea rose.

Ecologically, it almost feels like a step back into winter except for warm temperatures and longer days. The flowers are taking a beating and facing west away from the wind. Even the sea lions retreated to the sea and the young ones spent the day surfing and catching airtime. Some gulls seemed to savour the chance interact with high winds, doing skilled flying with high speed turns and tucks, while others hunkered down, facing into the wind and occasionally blown off their roosts. Geese were easily persuaded to flock off early.

Ocean surface temperature dropped from the last few days’ readings, by 0.1 degrees to 8.9o C. The mixing caused by the storm was palpable as large breakers’ tops blew off and the circular motion of the waves was exaggerated by opposing tidal currents.

There were no visitors and chores were routine. Photos were only taken through the window to save the camera from salt spray.

This photo doesn't really capture the mighty waves, but it gives you an idea.

There was nothing remarkable about the leaden morning with light and languid, north-northeast winds. Partially overcast skies cast a silvery pall over the Strait but bits of blue sky held promise for better things to come. The barometer held overnight at just above 1010 hPA and by mid-afternoon had dropped to 1008 As evening falls the barometer is holding at 1007. In the afternoon there was some sunshine but it was really a day dominated by cloud.

Five commercial whale-watching vessels were observed working in the Ecological Reserve today. Three were seen working in behind (south side) South Rocks and they were travelling very slowly and cautiously. Sea conditions were calm. The sea lions did not appear too disturbed by their presence. A few younger animals close to the water went in but it would be difficult to determine cause. On that note, military blasting continued as planned, from late morning to mid afternoon. Interceptor vessels and red flags warned boaters off. The sea lions and birds did not seem to react.

The wild goose chase continued and progress is happening. By early afternoon, most of the geese had retreated to the military zone to graze on the large lawn there. One pair staking out an area by camera 5 were more persistent, but eventually left for greener pastures. A couple of pairs of gulls were seen doing some of the broody things they do when nest building but as it is early yet, they are probably just practicing for the big day when they actually start to build a nest. The Pigeon Guillemots continue to flock here in the morning and leave in the afternoon as noted by Riley. Many were practicing walking on land today and in the water they worked the ebb flow through the rocks taking a ride and then flyew back upstream for another one.

A partially decomposed Northern Elephant Seal pup and part of its skull was located not far from the octopus in the boulders beach east of the Ecoguardian’s house. From the size, it appeared to have been a very young pup, if not premature, at death. The octopus was bigger. The plentiful, rich food sources are starting to explain the large number of eagles here daily.

A branded Stellers Sea Lions was photographed today 319Y and 4332 was observed. A California Sea Lion with a number on its rump and an X anterior to that was observed but the number was not verified nor was a successful photo taken.
