Back to Westerly Gales

Posted on by

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.

Octopus Ashore

West winds of ~25 knots brought heavily overcast skies loaded with rain this morning. The wind continued into the afternoon and the rain stopped occasionally while the sky brightened but remained dynamic and dramatic. As darkness fell it was still blowing 18 – 20 knots west. Barometric pressure rose steadily all day levelling off at dark, just below 1010 hPa. Forecasters call for light winds and showers here tomorrow.

It was a quiet day on the boating front with no whale watching or other vessels observed in the Ecological Reserve. Patrol vessels were positioned in Race Passage to ward off any unsuspecting boaters who might be venturing too close to Rocky Point and loud explosions punctuated lunchtime.

Ecologically, the day heralded spring, which is eternally welcome and now only a few weeks off. Mid-morning, Chunk, the woeful, sole remaining Northern Elephant Seal, shuffled off to the sea, leaving without destroying his daffodil pillow (see yesterday’s Log photo). The first few migrant shorebirds heading north, stopped and rested for a while on Great Race. I think they were Western Sandpipers. A small flock of Rock Sandpipers foraged on small invertebrates amongst the fresh seaweed turf.

A large, dead Giant Pacific Octopus was lodged in amidst the boulders on the south shore. It is hard to say what the cause of death was, but this is a species in which the female tends the eggs, while fasting, for seven months (or more depending on the temperature) and she dies soon after the eggs hatch. Lets hope that 50, 50,000 to  60,000 tiny hatchling octopods are tumbling out on the ebbing tide finding wee plankton to feed on and flashing colour signals to their siblings.

Right now the solar panels need extra help from the Lister generator for a few hours each evening but with spring on the way, there will be longer days and more intense sunlight levels, which will increase the contribution by solar generation. If anyone reading this knows of a small wind generation system that will not damage birds, please let Pearson College know about it. This is a windy place and could possibly be entirely weaned from diesel by using wind to supplement the mighty solar panels. The caveat is that the wind turbine can’t harm the birds that the Ecological Reserve is here to protect.

Wild Goose Chase

Posted on by

Last night’s north easterlies created a bit of a symphony: percussion on soffits accompanied by back door whistling its multifarious tunes. Morning started with the call of Canada Geese arriving, southerly winds (10 – 15 knots) and rainy skies. By late morning the wind direction had changed to west and the sky eventually cleared to a mix of sun and cloud by late afternoon. The gentle to moderate westerly is forecast to continue tomorrow bringing a 30% chance of showers. The barometer has been rising all day, so things are looking up.

‘Sports’ fishers were seen passing and fishing in the distance today and there were no sightings of whale watchers in the Ecological Reserve.

I went out to clear off the geese first thing and saw a pair mating in the water. That inspired me to ramp up daily goose patrols. No sign of nests yet, but there are a few pairs that are hormonally persistent. The large number of Bald Eagles is potentially helping keep the geese nervous. I saw an adult eagle flying with some sort of large bird, hanging from its talons but could not tell if it was a goose or a cormorant. The gulls seem to be setting up their territories, even though it still seems quite early for anything very serious. Pigeon Guillemots, Glaucous-winged gulls, and Black Oystercatchers are all in breeding plumage, as are many of the three species of cormorant.

Chunk actually moved today, leaving his dead, stink zone for fresh flowers and a sloped recline on the other side of the paths. I also saw him open one eye as I walked past, a small feat of energetic response. He really is wiped out from all of his male activities.

A California Sea Lion, which is equally lethargic, is hauled out beside the derrick and he looks quite emaciated with backbones and ribs showing. The rest of Sea Lions that remain look healthy and haul out tightly together in two spots, a small group just down to the northwest of the Science House and a larger group on the South Islets. There are a few branded animals but I haven’t been able to get photos yet. A male Steller’s 76Y (left side) and a couple of rump branded Columbian California Sea Lions. 76Y was branded at St. George Reef in northern California, just south of Oregon, in 2002 as a pup. 443Y is just going into its third year and was branded at Rogue Reef in southern Oregon, just north of the California border, in 2013.

Blue Sky Grey Sky

Posted on by

It was a blue-sky day at Race Rocks for most of the day, as the wind switched from west to northeast and then finally greyed over. The wind started light in the morning and rose to 36 knots NE, by late afternoon. The barometer climbed out its early morning hole of 993 hPA and dove back in as night fell. As I post the log it is falling past 989. The forecast is calling for the wind to drop and switch to southwest 15 to 25 knots Sunday afternoon and to light Sunday evening.

Four whale watching vessels were observed in the Protected Area today. They seemed to be travelling out to the west probably in search of migrating Gray Whales. They were a little more cautious on the south side, a trend, which tends towards sustainability.

The “sporty” halibut fleet was out fishing today. They anchor for the slackest part of the tide, spaced out like a beads on a necklace around the Ecological Reserve. Not all of them know about (or they choose to ignore) the ‘no go’ and ‘go slow’ limits of the Protected Area .

The reasons for speed limits in the Protected Area are the high density of marine mammals and birds and the location’s inherent dangers. Going slow protects the wildlife from boat strikes and reduces disturbance if boats stay far enough away. The no go areas also extend that protection to human life. I am not sure how many people have died in the waters around Race Rocks, but if it were a road intersection, it would have one of those high crash scene signs, combined with a wildlife crossing sign. I look forward to the day when boaters know and respect the rules. The quickest way for that to happen is by word of mouth and peer pressure. So if you boat in the area, please feel free to give others a friendly ‘reminder’ about the rules You might save their life. For the professional mariners, it is a very important part of being professional.

Chunk, the only remaining Northern Elephant Seal continues to slumber in the same spot. He has completely fried the vegetation where he is stretched out and seems to have lost a lot of mass since I saw him last fall. I guess he has been fairly engrossed with breeding, killing pups and fighting with other males. It must soon be time for him to head off and bulk up in the depths. He has massive “stretch marks” from slimming down to what looks like about 50% of his portly, fall physique.

There were a dozen Bald Eagles here today and the cormorants roosted on Great Race so it was possible to see the subtleties of the neon blue under the Brandt’s Cormorants’ chins and their whiskery white feathers.

The numbers of Canada Geese have risen rapidly, going from six, the day I arrived, to twenty by this afternoon. Canada Geese are protected under the Migratory Bird Regulations, however, they can wreck havoc on a tiny islet like Great Race, which is also used by other species that cannot easily, (unlike Canada Geese), nest elsewhere successfully. Like some people, they are loud, pushy and tend towards aggression, not making the best neighbours for nesting Black Oystercatchers, Pigeon Guillemots and Glaucous-winged Gulls. Although the status of all three of these nesting species, is ‘Least Concern’ as listed by the International Union for the Conservation of Nature (IUCN), we are hoping to keep them that way and discourage geese from staying (under strict permit from Environment Canada).

Other than wild goose chases, chores were routine today including camera and computer care.

Back on the Rock: March 2– 4th

Posted on by

Wednesday morning, while tide, wave height and current speed were just right; we slipped a crew change through a narrow window between two gales. As we waved goodbye, and I turned to get moved in, the barometer started to drop again.

After four and half months away, it was good to be back on Great Race with its familiar views of the Strait of Juan de Fuca. As an averred naturalist, I couldn’t help notice that North Rock was bristling like a military brush cut, with 350 – 400 cormorants. All three species Pelagic, Double-crested and Brandt’s, were ‘drying out’ on this strategic roost after foraging in the sea. An adult Bald Eagle swooped in and the cormorants en masse, hit the water. The tidal ebb started to clear them out to sea, pulled by moon and pushed hard by rainwater rising in the Salish Sea. The cormorants dispersed and the counting moment was over; some flew, some dove and others disappeared into the gloom, as more rain squalls swept in.

Concentrating on moving in and checking all systems in order, counts were put on hold for Thursday’s census. Chunk, the big, pup-killing, male Elephant Seal was lying where he had apparently been, on and off, for a week. He was a little too close to the path for comfort, which meant that coming and going to the energy building involved tip-toeing by, while keeping a look-out for his eyes to open and being ready to run, if necessary. Of course it is never necessary but absence makes the fear forget.

Riley left things fairly ship shape and I knew that everything was going to be fine when the old Lister generator roared to life. In the evening, the wind gradually rose to 36 knots, ESE, a speed and direction that makes the back door of the house whistle a weird, three-toned tune, but it didn’t keep me from a deep sleep.

Seawater sampling came early and the morning weather was fairly wet and windy. The sun broke out with rainbows in the afternoon and the wind dropped to less than 10 knots. As the sun sets now, the forecast is calling for light winds, a chance of showers Friday morning with rain again by afternoon.

Once established that it was a beautiful afternoon, three small whale-watching boats came out to watch the sea lions on South Rocks. It always makes me a little nervous to see them with their human cargo in close to the south reefs and the sea lions. Their insurance companies probably wouldn’t be too keen on that sight either.

Today was census day and there were interesting differences in the timings of comings and goings of different species. Today, the Pigeon Guillemots were here at first light and numbers kept increasing until about noon. They were all gone by late afternoon. The Black Oystercatchers were together in a squawky flock early in the morning and then dispersed. The sea lions hauled out mostly in the morning but additional individuals hauled throughout the day. The cormorants started roosting late morning and were mostly back in the water by late afternoon. The Harbour Seals hauled out in the late afternoon. There were few gulls in the morning, but by mid-day some were pairing up and looking like they might already be standing near their nest sites. By late afternoon there were over 200 gulls roosting on the island but they were gone by the time I came back from shutting down the generator at 21:00. The Killdeer, as usual arrived after dark.

The diverse temporal use of the Ecological Reserve by different species would be missed in a standard count where the observer passed through during a set amount of time. By having an Eco-Gaurdian here throughout the day, a much more thorough accounting of the different species use of the Protected Area is possible.

Here are the results of the animal census:

Friday’s weather was windy and wet. There was a lull early, as it switched for a short time to southwest but then turned back with a vengeance to strong northeast and big seas. The forecast is for a switching back and forth from southeast veering to southwest and back. It is blowing north 24 knots as I post this Friday evening, but is supposed to come down to light variable in the morning, rising againSaturday afternoon.

One whale watching vessel used the Ecological Reserve today and like yesterday’s boats, it too ventured into the danger zone of breaking reefs on the south side. The ebb was so large at the time that there were standing waves and a huge overfall along the string of rocks, islets and shallows. After a few tippy moments, they got out of there and I was glad they were all safe and sound.

I fought entropy today doing a few minor cleanups, making kindling and moving propane tanks around (downhill and empty). The usual chores also kept me busy. I tried to figure out what is going on with the camera, which has not yet fully cooperating. Now that I am through the technical barriers and able to post the blog I will be doing so daily and hope to post photos soon.
