Mirounga Manicure

Posted on by

The west-southwest breeze sprang up early and quickly cleared the low morning cloud, revealing blue skies and a rippled Strait. With a sustained westerly wind of up to 20 knots the ripples grew into chop with whitecaps by mid-morning. It continued to blow in the afternoon rising to a steady 30 knots with gusts over 35. By early evening with the wind relentless, it is rough and streaked in white.

The barometric pressure, that harbinger of weather, slid almost imperceptibly downwards today, yet the forecast for tonight and tomorrow is for more west winds in the same pattern. There was increasing cloud throughout the afternoon.

There were no whale watching boats observed in the Ecological Reserve today and only one sports fisherman who sped through the ER, cutting over to the southwest, his favorite anchorage spot to fish for halibut, just outside the closed area.

The Northern Elephant Seals have moved to a more convenient spot behind the boathouse, which is closer to the water and more in the lee under the heli-pad hill. The moult continues.

It is fascinating to watch the elephant seals use their digits and make what looks like a fist in a mitten of freshly moulted skin and fur.

Many pairs of gulls are mating now and I observed a pair of Black Oystercatchers doing the same. Some of the oystercatchers may already have eggs. I am taking clues from the raven that frequents the island and is always interested in a couple of pairs’ territories. The raven really riles up the oystercatchers, who fearlessly mob it. It was so windy today that while the chase was on, the raven tried a tuck to avoid being hit by an oystercatcher and almost lost control.

 

The eagles were fishing early but left when the winds came up. The photo below finishes the series I started a few days ago, to show how the eagle tucks the fish up under its tail in flight.

Spring Wind Blowing.

Posted on by

It was a day defined by wind, starting in the wee hours of the morning, with 30 – 40 knot northeasterlies which calmed just after dawn, then switched to equally ferocious westerlies. The afternoon westerly subsided to 20 – 25 knots early then built back up to 25 – 30 knots as I post this log blog.

The barometer’s fall, started Monday, was short-lived: it started to rise again in early hours today and is leveling off as the day ends. The forecast calls for afternoon westerlies tomorrow and the gale warning remains in effect. They are calling for only a 60% chance of showers and precipitation is taking on new meaning here south of latitude 48o18’ N. What we consider normal rain and showers on the outer coast just doesn’t materialize in the same way here in the Mediterranean climate of Race Rocks. It is so much more of a desert than the outer west coast.

I only saw one whale watching boat today and they were travelling east, well south of the Ecological Reserve. Sports fishing boats were also notably absent. Very wise considering the sea state, wind and current conditions today.

The Northern Elephant Seal moult is taking a new dive into the unconscious with fewer hours awake and active. Some animals have not moved more than a few metres in 24 hours. The larger females seem to be leading the race to moult and the two biggest females and largest male are almost 75% moulted. The soft grey fuzz look is taking over from a once brown and tattered look.

Two of the larger animals on the island are close to 75% moulted, a male (left) and female (right). Young males behind are not as far along.

The seals are also moulting their “whiskers” which are referred to by biologists as vibrissae. It is thought they vibrissae are helpful in detecting vertically migrating prey at depths of greater than 500 meters. Of course it is a bit hard to make observations in situ but recent anatomical work on how these whiskers are enervated revealed over 1500 nerve axons per vibrissae giving more weight to their importance as sensory organs.

This female elephant seal has moutled her facial hair and skin, revealing a soft looking gray fuzz. Note that the "whiskers" and "eyebrows" are also moulting. These are important sensory hairs called vibrissae.

The Steller’s (or Northern) Sealions, and a few California Sealions continue to haul-out on South Islands and I spotted a brand today on the youngest Steller’s that I have yet to see here. #460Y was branded as a pup at St. George in northern California, in the summer of 2013, making it less than two years old at this stage. There are several other Steller’s Sealions that are the same size and appearance that may also be that young.

 

#460Y was branded in July 2013 . This young animal and probably several others its' size are less than two years old and may still be nursing occasionally.

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.

 

 

Beautiful Spring Day

Posted on by

The wind didn’t do much until mid-afternoon when the westerly came up and blew 10 – 15 knots. Velocity kept increasing during the afternoon and evening and as the sun was setting it was blowing a steady 30, gusting to 35 knots. It was a very sunny day with 354,000 watt-hours per meter2 accumulated throughout the day. The barometer continued its slow descent begun on Saturday and is heading inexorably towards wet weather in the forecast. Although it is still supposed to blow west tomorrow, with showers, the rest of the week looks darker and wetter.

A couple of whale watching boats were observed in the Ecological Reserve today: both were proceeding with caution, at a minimal speed and staying a respectful distance away from the wildlife. These companies are practicing sustainable wildlife viewing practices. One rental boat was observed speeding in reserve.

The Northern Elephant Seal moult continues and is becoming more visible on the older animals. The measuring device was modified to allow for more accurate length measurements and the animals continued to cooperate by going one by one, down the ramp and into the sea for a swim. #5850, the young male tagged as a weaner in 2012 was stretching bull kelp stipes today, a biomechanics activity done by phycology students everywhere on the west coast. No teeth involved, so no confounding tearing factor.

Westerly Winds Prevail

Posted on by

 

Well it blew hard west, west-southwest all night and all day without let up. I didn’t see the tower anemometer drop below 20 knots and it was often gusting to 30 (and over last night). Although there were a few serious clouds and showers that came through it was overall a sunny day and the barometer climbed high and fast in the late morning, slowing to a more gradual ascent in the afternoon. The forecast continues to be the same with a strong wind warning in effect but winds are forecast to drop to 10 to 20 overnight and become light in the morning.

There were no boats of any kind in the Ecological Reserve today. It was a wild place with the wind combing whitecaps, on top of a big oceanic swell. Beautiful to watch from shore but not something you would want to be out in, especially in a small boat.

The ecological happenings are subtle right now. There is nest building, courtship, egg laying and brooding, lots of resting and sleeping by the seals and sealions and continuing predation by the eagles. The Northern Elephant Seals visiting Great Race spent the day sleeping in the heritage garden and another 22 animals could be seen asleep on Middle Rock bringing the total to 27. These are mostly sub-adult animals and some of them appear to be starting their moult. This time on land looks really labourious for them but it is important in building bone density to have some weight bearing time ashore.

I believe that the animals here on Great Race now are the some of the same ones that were here in the fall. It is easy to know for sure with the tagged animal and I am quite sure with one other animal that had terrible looking psoriasis last fall and still does now. The only place the skin is not scratched raw is under the flippers. The others look really familiar too but that could just be their generic elephant seal look.

It was sunny enough to run the desalinator off the solar energy today and it always feels good to know that the sustainability plan is paying off. Now we just need to add to the suite of diesel alternatives and wind is such a natural for this site.

Lawn Crushers Extraordinaires

It was a cold and blustery day with winds from the west-southwest, blowing 25 to 35 knots. It was also dark, with a cumulative solar radiation of only ~130 Langleys and a peak of less than 500 Watts/m2, which was half of yesterday’s high. The temperature was about 6o C most of the day but it felt much colder in the wind. The barometer bottomed out around noon and although the trend is rising it seems tentative. The forecast is calling for a little less of the same, with a gale warning for Central Juan de Fuca Strait and an expectation for westerlies to blow 25 -25 knots again by Tuesday evening.

In late afternoon there was one brave, little whale watching boat in the Ecological Reserve. No other vessels were noted in Reserve today.

The folks on the tour boat were watching the sealions on the south side. The sealions which are usually hauled out on the rocks there these days, were almost all hanging out in the water where it was a few degrees warmer than the air and even cozier for a wet animal in the wind.

The lawn was freshly crushed, by four Northern Elephant Seals today. It certainly beats mowing. All but the one with the skin condition woke up after a profound 33 hour sleep to “romp” in the grass. The two young males sparred and a larger male and female practiced for parenthood. They all conked out after about three hours of activity and are now back into deep sleeps. The tagged one (5850) left yesterday afternoon and was not seen today.

The Mist Maidens, which I mentioned a few days ago, are a rare plant found on Race Rocks and they seem to be doing really well. They don’t live in places frequented by the elephant seals so are safe from that threat. I will repeat Courtney’s documentation protocol in May to confirm or deny my qualitative impression that they are doing well.

Tracy's Mist Maidens, or Romazoffia tracyi are a rare plant that appears to be making a come-back on Great Race Island in the Race Rocks Ecological Reserve.

The solar panels did not put out much energy today as could be expected from the low light levels. I had to start the generator early and run it a little longer, due to low solar power. It would really be great to have a small, bird-impermeable, wind generator for days like today and to supplement, the rest of the time, as it is usually windy here.

Other than the daily chores, I concentrated on risk mitigation today starting with locating and going through first aid kits. I tried to order first aid supplies and started a health, safety and environment risk mitigation report.

Dramatic Weather

Posted on by

Strong west-southwest winds blew all day with a continuous cycle of showers and dramatic clouds scudding through. Wind velocities ranged from 10 to over 30 knots, up the tower. A low snowline could be seen in the Olympic Mountains from time to time and the air was chilly. The barometer has been climbing steadily since last night and the forecast is for more of the same with a risk of thunderstorms.

No tour boats or fishers were observed in the Ecological Reserve and Rockfish Conservation Area today.

A Sea Otter was spotted in the main channel in front of the eco-guardians’ house again today. As the tide turned, it swam over to Turbine Rock and on arrival was surrounded by six or seven small Harbour Seals. The adult seals remained uninterested, asleep on the rock. Through the spotting scope, it looked like interspecies play with lots of exaggerated diving and washing up onto the rock and back out. This is one of the first times I have looked at a sea otter for any length of time when it was not eating, grooming or sleeping.

Three Northern Elephant Seals moved right up onto Great Race today. When I did the water sample at six there was one individual lolling around by the jetty. I looked up mid-morning and three of them were doing the wave along the walkway. One stopped at the intersection, one went back closer to the boat shed and the third went right around the science house onto the rocks on the west side.  None of these individuals were tagged. Once settled, they slept soundly for the rest of the day.

Most of the Canada Geese are sitting on eggs already and the ganders are fearless defenders. I am trying to discourage one insistent pair of geese that haven’t laid yet (I think) from nesting right beside the path to the Energy Building but it seems to be a losing battle.  The area near the stone burial cairns has been seriously overgrazed by the geese and the earth around the biggest one is eroding around the edges. In that area the goose exclusion cages show up a large difference between grazed and un-grazed (caged). In other areas where crab-grass dominates there is little difference inside and out of the cages.

Dawn broke in reds and pinks heralding another glorious day. Early on there were feeble zephyrs from the southwest and east but the most obvious wind tell-tale on Race Rocks, the Canadian flag, hung limply most of the morning. Westerly breezes started in the early afternoon and developed into moderate breezes, late afternoon with gusts to 23 knots. The strong wind warning forecast is downgraded now to 15 to 20 knots westerly, overnight in the central Straits of Juan de Fuca and it is already dropping, as the sun sets.

No tour boats were observed in the Ecological Reserve although one hardtop sport-fishing boat cruised past the sea lions at a respectful distance and speed.

A Northern Elephant Seal visited the marine railway for a snooze on the falling tide this morning. It was a perfectly symmetrical ellipsoid. From the light tower another 16 elephant seals could be seen on Middle Rock. Two more in the shallows of Middle Rock, looked so much like smooth rocks draped in seaweed, that they had me fooled for a while. That makes 19 in total, a high count for me so far.

There have also been a lot of Bald Eagles present with a total of twelve individuals today. I have been trying to figure out what they are eating and have seen them chasing both gulls and geese.

I have also seen some casualties, including three gull carcasses but they do not have the look of eagle food. The one in the photo above is completely pristine even after several days, with no trace of blood or predation.

This evening the eagles caught and ate something but I could not tell what it was, there were no feathers at the site where they were dining but it may have been turned inside out (skinned). Four adults and two sub-adults fed off the one carcass.

Alex continues to be my only visitor and we had a belated Easter dinner, highlighting delicious, fresh halibut. I wonder when the last time was, this kitchen had freshly jigged halibut? Alex resurrected a bench that was both broken and had missing parts. It now sits in front of the Science House with a view out to sea and east up the Strait.

The phone and Internet went off again last night and I didn’t realize it until late. The problem was different this time and required a UPS reset in the tower this morning. I am getting quite adept at restarting the weather system now and we also tried (again) to fix the wind direction indicator on the system. I had success getting the underwater camera going again but it really needs a good scrub. The desalinator filled up the water tank again, running on sunlight through the solar panels. I cleaned up the visitor sign-in cabinet a little and put in some fresh pamphlets about how the public can support Race Rocks through Pearson College.

Note this blog posted next day due to yet another failure of phone/Internet last night due to UPS overload in tower.

Back on the Rock

Last night’s storm blew in just as shift-change finished. Nick Townley waved goodbye from Second Nature as Chris Blondeau, still in his dry-suit from the diving activity, pulled the vessel out into the tidal stream and headed her back to Pedder Bay.

Six students from Pearson College came out to the rock for the weekend and I started my shift with great company. Their goal was to catch up on studies (and sleep (my guess)) and to have their own experience in this gem of a biodiversity hotspot.

As we unpacked and settled into the two houses, heavy rain followed the black horizon moving in quickly from western Strait of Juan de Fuca. It was very nice to be snug inside as it was a wild night with heavy squalls. There were quite a few rattles and thumps that I didn’t recognize from last fall’s storms. Morning broke with gusts over 30 knots in the tower and alternate clearing skies and rainbows shone through and faded out on all sides. It was a white water scene with wind and current colliding in a frenzy. The barometer which had taken a nose dive Thursday and Friday, climbed back up to over 1024 HPa from Friday’s low of 1009. By noon, the westerly winds had dropped to 12 knots and the afternoon and evening was uneventful; overcast with showers and light winds shifting to northwest.

Although there was no fishing activity in the Ecological Reserve (ER) today, five wildlife viewing tour boats were noted. I was surprised by the number of both Northern and California sealions still hanging out and there were at least 75 Harbour Seals hauled out in the afternoon (not a complete count. I saw two pairs of adult bald eagles and numerous other birds including Canada Geese, Black Oystercatchers, Harlequin Ducks, Black Turnstones, Pigeon Guillemots, Double-crested and Pelagic Cormorants and an interesting mix of gulls. Many of the Glaucous-winged Gulls are already paired up and getting excited about spring. They are scattered around Great Race in all the places that there were nests last year. A much more condensed flock of gulls with about 100 birds was hunkered down in the lee of the rock on the west side of the science house. This flock was a mix of some unexpected visitors including Herring Gulls, Ring-Billed Gulls and even a few California Gulls, probably en route somewhere else. As dusk fell last night I heard the calls of Killdeer and it really felt like my home away from home.

It was great to get back up the tower again and have a good look around and for fun and more exercise, I started clearing off some of the winter’s woody debris accumulated on the marine railway. Greenlanders Hana and Malou joined in and we made it into a bit of a game, practicing our aim and strengthening arms. When we finished there was a stream of wood heading out to sea and we hoped that the whale watching boats were avoiding the busy tide lines.

March 14 – West Wind and Waves

Posted on by

Overcast and rain in the morning, sunny in afternoon
Wind: 1-11 knots from the W and N in the morning, 22-46 knots from the W from the late morning onwards
Air Temperature: Low 9.3°C, High 11.3°C
Ocean Temperature: 9.2°C

A gale warning in the afternoon, with winds gusts up to 46 knots, remained in effect for the rest of the day. The gulls had a hard time sitting and claiming their nesting sites when the wind gusts reached 46 knots. Due to the winds, the afternoon was filled with indoor tasks like cleaning, organizing the basement and drinking tea. The winds diminished in the evening.

Hanne Christensen, one of the visiting Pearson students, took some photos around the island yesterday and today. They are included in the gallery below.
