Finally Field Exam.

Posted on by

It blew west 15 – 20 knots all day as the barometer slowly climbed to 1016 hPa and leveled off. The early, overcast sky gave way to sunshine by late morning and it continued brilliantly until sunset. The forecast is for more of the same with the strong wind warning continuing.

Two whale watching boats were observed working in the Ecological Reserve and both followed guidelines and regulations, treating the Reserve and its wildlife with respect. Several sports fishing boats passed through the Ecological Reserve at low speed and only one halibut sports fishing boat was slow to slow, in the go-slow zone, doing at least 15 knots but eventually remembering and slowing.

All of the ecological happenings reported on, in the last week or so continued today. Great Race was busy with Northern Elephant seals coming and going from their bathing routines, moulting, sleeping and jousting. The gulls, guillemots and oystercatchers continued to prepare for the next generation and Canada Geese were out and about, promenading their goslings. A raven was seen taking one small gosling that had been noted dead earlier, near a nest in front of the science house. Both species of sealion seem more vocal this week, with the Steller’s mostly on West Rocks and the Californians more spread out but definitely back at South Islands.

Today was busy with visitors as Laura and 36 first year marine science students arrived early to do their marine science field exam. Chris and Courtney, shuttled the class out in Second Nature and Hyaku. An extra trip in Hyaku brought out author Peter Johnson who is researching lighthouses for an up-coming book, along witha guest photographer. Hanne, a second year marine science student from Pearson College also arrived on that trip and she photographed the first years hard at work and enjoyed observing elephant seals with Courtney.

‘Delightful dichotomies and wondrous waves’ is the intriguing title of this exam station.

My family continued their visit and helped out in lots of different ways, from assisting boats and people on the jetty, to encouraging me in becoming more proficient and comfortable running the derrick. I assisted Laura and students with the field exam, which is very unique. This is one exam the students will  never forget.

 

 

 

How Low Can It Go?

Posted on by

Thick fog met me at dawn, not the sleepy kind that coffee cuts through, but dripping wet, zero visibility, fog created through the convergence of cold ocean water and warm air. The fog retreated and advanced repeatedly before it was beaten back by high wattage sunshine. The westerly wind blew throughout, at 5 – 15 knots only rising near sunset to closer to 20. The barometer started a gradual drop in pressure late morning yet the forecast is for sunshine and continuing westerlies.

There were a few whale watching boats in the area mid-morning with two observed in the Ecological Reserve. Sports fishing boats were seen in the general area but outside the Reserve.

The elephant seals found the trek to seawater quite an effort today and some of them gave up for a few hours on the way to have a swim. Getting back up the hill was even more of an effort.

The tide is a long way out.

The tide is a long way out.

Observational efforts were focused in the inter-tidal and on the mega-fauna census today. Another really good tide (0.5m) allowed me to do a large algal survey and find more marine invertebrate species. I will share some of the invertebrates here and come back to the seaweeds tomorrow. In each photo, if you look closely you will notice smaller and smaller animals in a wall to wall competition for space or is it sharing of space.

The human history and natural history are intertwined.

Both the natural and human history at Race Rocks are profound.

California Mussel beds are ‘old growth’ and substantial on Great Race. The large area provides important habitat creating significant diversity.

The mottled sea anemone (Urticina crassicornis) is quite common in the low inter-tidal on the south side of Great Race.

Urticina crassicornis

This species of tubeworm, named after Vancouver (Eudistylia vancouverensis) is usually more abundant sub-tidally. Here in the high current area between Great Race and South Islands, it is common in the low inter-tidal.

Eudistylia vancouverensis There is a lot of gigantism on the Pacific coast but here at Race Rocks even the giant species seem even more abundant and bigger than I have seen them elsewhere.

Cryptochiton

The gumboot chiton (Cryptochiton stelleri) is an important grazer in the inter-tidal. They are very abundant here.

Katharina

The Black Leather Chiton (Katharina tunicata) is another grazer and like the gumboot chiton grows both very large and is super abundant here.

 

Cucumaria Dodecaceria

Orange sea cucumbers (Cucumaria miniata) are really abundant both in tide pools and under the edges of boulders and there a lot of boulders on the south side.

 

Three species of sea urchin were observed today, adding the green urchin (Stronglyocentrotus drobachiensis) to the list. The green and purple both like to “dress-up” aka cover themselves, with shells, seaweeds and even bits of wood. Here they were using empty limpet shells in an area frequented by oystercatchers.

Enter the Merry Month of May

Posted on by

The wind was just a zephyr today, with a weightless push from south, then southwest, and then nothing for a while. Not much to sail with and the flag hung lifelessly. The barometric pressure was similarly lethargic, going up ever so slightly, then down by about the same. The strong wind warning continues, so it may get here by Sunday evening and the forecast is for sunshine.

There were no whale-watching boats in the Ecological Reserve today although a sports fishing boat came by to look at the sealions in the evening. One rental boat from Pedder Bay with three men, insisted on fishing for and catching rockfish in the closed Rockfish Conservation Area, while the regulars were well outside. There needs to be more notification and communication about where the conservation area is located.

The bull kelp has reached the surface at low tides and is forming fairly massive beds around Turbine Rock where the Sea Otter likes to hang-out. In by the jetty where the current is less active it is at the surface all the time now and some of it is very reproductive, with large sori patches visible on the fronds.

Bull kelp fixes carbon faster than just about anything and grows so fast it makes bamboo look like it is standing still.

You can easily see where reduction division (meiosis) happens in the lighter yellow spore patches. You can also see where early patches have popped out of the frond and drifted off.

 

The pair of geese nesting at the base of the light-tower were out walking their goslings today. It looks like five out their eight eggs successfully hatched. The gander belonging to another, younger pair gave himself a real scare today, walking past the basement door where he could see his own reflection. That was really troubling to the pair and also very noisy. The gulls are also noisily going about their business.

The elephant seals continue to moult although a few of them are down to just a few eyebrow hairs now. The younger males seem to be the last to moult and the most active. The same 12 to 14 individuals continue to frequent Great Race.

This almost three year old male (#5850) continues to spend day and night on Great Race. He has finally started to moult.

California Sealions were hauled out on Great Race today for the first time since I arrived in March and there was a male Californian (sealion) on the jetty that didn’t want to leave when I went down to sample seawater in the afternoon.

The solar panels were well supplied with sunlight today and produced enough energy to run the de-salinator and top up fresh water supply. The high value was 900 W/m2 and the cumulative amount for the day, at 7:00 PM broke the week’s record.

There were no visitors today and maintenance included routine chores and a couple of little projects.

A Changeable Spring Day.

Posted on by

During the early part of the morning, the flag hung vertically, stuck to the flagpole, wetted by fresh rain. Later in the morning, when it occasionally fluttered, it was from almost imperceptible, easterly zephyrs. After lunch it blew north 10-15 knots for a while before switching over to the afternoon westerlies mid afternoon. Although there was significant rain (see figure below) throughout the day, there was also lots of sunlight and we surpassed yesterday’s level by over 30%. The barometer started rising in the early morning and by 17:30 was at 1008 hPa. The forecast for Saturday is for a continuation of the afternoon westerly pattern.

Only one whale watching boat was observed in the Ecological Reserve, just at dusk, although several headed west and back through Race Channel. One sports fishing boat fished very close to the boundary at Rosedale, but clearly outside. The Life Saving vessel ‘Spirit of Sooke V’ came through middle Channel this afternoon at a very stately pace and then swung around and went in between South and Great Islands and returned to the west.

A pod of at least four Killer Whales passed to the south of Race Rocks, heading west at ~07:00. It was not possible to determine which population and there were probably quite a few more than four. They were quite spread out and moving fairly fast, travelling about half way out to the US/Canada border (yellow can buoy) from Race Rocks. A flock of 23 Black Brandt flew through Middle Channel about the same time, also heading west. The Barn Swallows appear to be staying on the island somewhere; at least they were here bright and early. This place is certainly a haven for an insectivore. I hope they stay.

The Pigeon Guillemots are spending more time on land as spring progreses. These true seabirds are ill equipped for walking with their feet used as rudders for underwater flight, and set far back on their muscular little bodies. I don’t think they are actually nesting yet but certainly getting use to land. Their favorite roosting spots are in the surge channel between the energy building and the science house, on the jetty and its’ upland scree and cliff area and on the little cliffs just southeast of the light-tower.

Now that the winds have settled down, the eagles are back and making determined attempts on the Canada geese. They also spend a considerable time on the pinniped haul-out rocks.

I keep expecting the Harlequin Ducks to leave and head for the mountains, where they nest and lead their summer  lives. There are at least four here still and probably more.

Harlequin Ducks are also supreme under-water swimmers and specialize in white water: in rushing mountain rivers and streams in breeding season and in the sea the rest of the time.

A new (to me), young, female Northern Elephant Seal joined the Great Race elephant seal group today bringing the total to nine, five males and four females. #5850, the three year old male, embraced the new female (literally) and although he is the smallest of the males on the island, while the other males were practicing their jousting he had his ‘pinky’ out and was snuggling up to the new arrival. It is the first time I have seen seals hold ‘hands’.

A student group is arrived just before dinner and are staying over. They will be part of a first year biology field trip that will be here most of tomorrow. Work was routine today but the day was anything but routine. Amazing place.

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.

 

 

April 12

As the sun set, the wind shifted around to south-southeast after blowing about 10 knots  from a westerly direction most of the day. The snow line across the Strait is very low and the chill in the air continues. Although there was some sunshine today producing a high solar radiation reading of 1,000 watts/m2, there was also a lot of cloud. The barometer reached a high of 1020 hPa mid-day and then began to fall. The forecast is for southeast showers switching back to westerlies tomorrow afternoon.

Only one tour boat was observed in the Ecological Reserve today and although there were dozens of sports-fishing boats all around the reserve none were observed inside.

American Pipits have been spotted bobbing and flitting around Great Race and there is a photo below as evidence. Thanks go out to Rocky Point Bird Observatory for the identification confirmation.

Six Northern Elephant Seals came ashore at first light and spent the whole day sleeping in the garden. One was a tagged, with a pale green tag #5850. This same individual had two tags when I first saw it last fall, October 14.

The Canada Geese are in over-drive right now and uber-territorial. One pair tried again to take up residence in the entrance way to the de-salinator room which is just not going to work.

The Glaucous-winged Gulls are engaging in more definite pairing behaviours and also becoming more territorial. Many are nest building, pulling out chunks of grass turf for padding. Black Oystercatchers are looking broody too and I observed Black Oystercatchers eating limpets today.

 

There were no visitors today.

 

Gorgeous Day.

Posted on by

What a gorgeous day. It started and ended on equally lovely notes and was nice in between. It was clear all day and light breezes from the east, eventually swung around to the west. The barometer was fairly steady, not doing much and the forecast is for those westerlies to come up tonight and tomorrow.

It is incredibly beautiful here right now with the flowers blooming everywhere, a legacy from light-keepers with gardens. Tulips, daffs, bluebells, grape hyacinth, snapdragon, phlox and calendula are everywhere, reminders the long history of the place going back to when light-keeping happened here at Race Rocks, before Canada was a country. The stone cairns bear witness to people using this place long before it was a light station and a worry today is that the Canada Geese are over-grazing and trampling these iconic and ancient cairns.

I was off-station today, my first trip since arriving twelve days ago. Everything worked well including the winch, marine railway, carriage and the Boston Whaler with its Yahama engine. Alex (my husband) came back with me and will spend a few days here.

Emil, one of the Pearson College students here over the weekend sent me this photo to include in the blog. You can see that they were enjoying being theatrical and generally had a great time on the rock.

It is all in the branding

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.

April 4th – Full Moon and Blood Moon

Posted on by

The weather was much more subdued today with light winds and a morning switch in direction to the east, northeast and then back to westerlies at sunset. The sky was partially overcast but more sunny than cloudy with only the slightest of showers. The barometer continued its very slow and not very steady, decline that began on Thursday. The forecast is for more of the same. Today’s full moon was in total eclipse early this morning and although I was up at 5:00 AM, I did not see it, maybe that is because it was totally eclipsed ; – )?

Only two tour boats were noted within the Ecological Reserve today and they both kept their speed down and seemed to be very respectful of the wildlife. There was no fishing activity noted inside the Conservation Area.  A couple of Kayakers were paddling in the Ecological Reserve today and they were very close to the sea lions. They managed to make it past them without any disturbance, but the sea lions woke up after the kayakers passed. They were only concerned enough to do some neck craning and alert behaviour before falling back asleep.

Ecologically things were very much like the previous two days, the gulls are slowly becoming a little more territorial and parental looking. I saw two holding nesting material in their bills today and several pairs were doing a synchronous bill down dance that might demonstrate to the other how beautifully they will be able to regurgitate into any chicks they might produce together. I also witnessed some nasty bill holding that drew blood and descended into an outright wrestling match. I was not sure if these gulls were territorial competitors or mates but they were determined to not let go of each other. Gulls are supposed to mate for life so it makes me wonder, when I see the same gulls sitting poignantly all alone, on their spots, day after day. Is their mate missing in action or just late?

The Canada Geese are very broody and in some places are running the gulls off. Some geese are already incubating four to eight eggs per clutch.  I guess the crows know this and there is often a small murder of crows strutting around the nesting areas and also being chased off by the geese.

The Bald Eagles are here all day everyday right now and I watched one adult chase off another so there must be something good to eat. Is it gulls? The chase was quite spectacular with climbs and dives and at one point, upside-down flying in self defence. The defeated intruder headed over to Bentick Island.

It wasn’t sunny enough today to just go with solar power and I had to run the generator for a couple of hours in spite of having no extra draw on energy. I know the day is coming when there will be enough sunshine to go through a whole day, entirely on solar power.

Thirteen visitors came to the island today. Chris brought out a group of eight students and his son accompanied him with a school friend. Alex was deckhand again and brought his father who was visiting, along for the brief version of the Race Rocks tour. Alex’s Dad likes using the Race Rocks video cameras, so one more reason that I need to figure out how to get cameras #2 and #5, back up and running. The students will go back mid-day on Monday and are already earning their keep.

Chores were a mix of entropy fighting of  today. It was really nice to know that there is lots of water in the midst of churning compost and the usual tasks. I am still tidying up wood and very grateful to Alex and Virginie for all the firewood and lovely kindling. I also want to thank Nick for leaving the house so spick and span, very nice.

Almost the end of March.

Fog from overnight burned off in the late morning revealing a beautiful day. Although the barometric pressure continued its gradual decline from yesterday, the winds were less than 10km/hour at ground level until early evening when a gentle westerly started. As the sun is setting, clouds gather in the west making god rays and but no sailor’s delight colours. The forecast is calling for showers and possibly even thunder and lightening on Tuesday afternoon and near gale force winds are expected to the west.

There were eleven Elephant Seals visibly hauled out on Middle Rock today and over 115 Harbour Seals hauled out, scattered on all the islets and rocks. There are many birds on and around the Reserve right now and I look forward to next weeks census. I am trying to persuade the usual gaggle of geese to move on but they are pretty persistent and in some cases quite peevish. While looking for nests, I came across several goose wings so something has been eating them, probably either the otters or the eagles. A total of four tour boats came to the Ecological Reserve to searching for that sort real life adventure, and viewing wildlife in glorious, afternoon sunshine.

That sunshine powered solar panels and batteries so well that the generator run time today was 50% of the daily average over the last two weeks. As day length grows, this will become a continuing trend. The solar panels are a really important piece of the sustainability puzzle on Race Rocks. Over the years Pearson College has done really well in reducing its dependency on fossil fuels on the island and the solar panels are big part of that reduction. Going from eight large oil tanks to one is a big step and of course also helps mitigate spill risk.

The reduction in emissions is not only helpful in reducing greenhouse gas and improving air quality, it is also helpful to the ocean. Ocean acidification, a lowering of pH due to atmospheric carbon dioxide uptake is a serious issue that some people call “the other C02 problem”. Our very close neighbours to the south, in Washington State are taking the threat of ocean acidification very seriously and are mobilizing to address this threat. Their efforts were precipitated by the near collapse of their oyster industry due to ocean acidification. It would be great to add a good pH meter to the kit here in order to monitor that aspect of water quality as ocean water sweeps past Race Rocks and into the inland Salish Sea.

Chores today included seawater sampling, sorting, moving and stacking wood, sweeping walkways, rotating composters, and keeping an eye on activities. The underwater camera is back up and running due to a quick fix and I have started to get to know the computer and its myriad of files again. There were no visitors today and I missed the students who were here on the weekend.
