Blooming Thrift

May 3

The weather today was very similar to yesterday’s, with a flip flop breeze most of the day, finally becoming a 15- 20 knot westerly as dusk approached. Temperatures were a little warmer, 14o C and solar radiation levels about the same. The barometer is still dropping and the short-term forecast looks like more of the same with raining arriving Tuesday.

 

Two whale watching boats were observed in the Ecological Reserve this morning and a dive charter vessel supported divers in the ER.

Eagles continue to hunt in the ER as does a lone raven that visits daily and drives the oystercatchers mad.

 

Bald Eagles have been observed catching fish and chasing Canada Geese and Glaucous-winged Gulls in the last few weeks. As long as the wind is not too strong, they are here daily.

There were 15 elephant seals on Great Race this morning and most of the day. Their moult continues.

I spent a bit of time in the inter-tidal today and soon discovered that the memory cards in the camera were full so I spent a lot more time culling and sorting photographs indoors.

 

Phylospadix scouleri, also known as surf grass is found in the low tide zone and the top of the sub-tidal. Here it is mixed with Desmarestia aculeata and bull kelp Nereocystis lutkeaena both subtidal species.

Many of the species found in the inter-tidal at Race Rocks are more usually associated with outer coast, more wave exposed sites. The current here makes it a very rich hotspot for marine biodiversity.

Enter the Merry Month of May

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.

Mirounga Manicure

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.

Notice the fish tucked up under the tail.

April Almost Gone

The wind didn’t do much today other than puff a few light breezes in from the west with a few periods rising to 5 to 10 knots. It was mostly overcast with a few bright interludes and generally rather unremarkable in terms of weather. When the sun did shine through it had intensity foretelling the growing season. The barometer was fairly steady all day and is just starting to drop as I write this. The forecast is for a mix of sun and cloud, a chance of showers and a strong wind warning in effect for Friday afternoon.

There were nine whale watching vessels observed in the Ecological Reserve today, a bit of a spike, possibly due to a large cruise ship at Ogden Point.

I watched a Harbour Seal tearing up and eating a fish today. It looked like it might have been a lingcod (Ophiodon elongatus).

This female elephant seal has no tags and I have been calling her circle sister because of the circular marks on her back. As you can see her moult is almost complete and the circles are  at least a little visible on the new coat so I will still be able to identify her as an individual.

This is the back left side of the newly moulted "circle sister", still identifiable by the small circular scars.

Crankypants Has a Number.

By mid-morning, the light southwesterly winds left over from yesterday’s blow had wandered over to south and they stayed southerly until early evening when they turned back to west. The barometer continued the slow ascent begun early yesterday, throughout the day. Although there was a mix of sun and clouds today, light levels were high and reached over 1000 W/m2 at the peak. Forecasters are calling for strong westerly winds again, with a chance of showers Thursday.

Four Whale Watching vessels were noted in the Ecological Reserve today, visiting on return from the west, heading towards Victoria. No sports fishing vessels were noted in the ER.

The Canadian Coast Guard Helicopter (Fisheries and Oceans) dropped by today to service the light, which went dark the night before last. Dave (pilot) and Derek (technician) were a welcome sight in their lovely little Messerschmidt, which was carefully put down at the base of the light tower stairs.

Ten of the elephant seals managed to go through the measuring device today while I was sitting, waiting for them with the camera. I also spotted tags on the young female Northern Elephant Seal with serious skin issues. I may have mentioned her in a previous blog, I called her psoriasis sister last fall and Courtney named her crankypants in spring 2014. She is very vocal and easily disturbed by the other seals. She is usually off by herself but today she was caught in a traffic jam for daily ablutions, which really seemed to upset her. I have observed her many times last fall and this spring but never noticed the tags before. She moves as if in pain, complains loudly and leaves a trail of blood. She has many open wounds that look like holes and cracks. The right tag is number A114 and although it is difficult to read the left side, it is perhaps A476. She has all four tags still.

A branded Steller’s Sealion # 411R was noted today. She looks big for a female but that is what the record says, branded as a pup in July, 2005 at Rogue Reef, which is in the very southern end of Oregon. I will check with Pat Gearin on this identification.

Spring Wind Blowing.

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.

Fine Day in Spite of the Forecast.

Light northeasterly winds brought some morning showers and kept it cool until late morning. The light northeasterly continued in the afternoon but solar radiation levels went up to a high of over 800 watts per m2 bringing up air temperature to a high of over 13oC. The barometer was fairly steady until noon and then started to fall very gradually. The marine forecast has a strong wind warning in effect overnight diminishing to a 20 knot westerly by early afternoon tomorrow. As I write this in the early evening the north-northeasterly is freshening to over 20 knots.

Three whale watching vessels were observed in the Ecological Reserve today… Sports fishing vessels were observed fishing nearby but not in the ER.

More measurements and individual moult progression, observations were made on the Northern Elephant Seals on Great Race today.

Killer Whale # T103 possibly.

The day started with a gorgeous sunrise with lots of golden light pouring under a low violet cloud layer, scattering pinks, reds and oranges. The wind was out of the northeast at 10 – 15 knots and stayed that way until early evening when it turned to west. The barometer continued the climb it started Friday morning, until late in the day when it hit ~1020 hPa and levelled out. The forecast is for east winds and rain.

Six whale watching vessels were noted working in the Ecological Reserve today, one in the morning with a videography crew and five in the afternoon associated with the Killer Whales. Five out of six totally respected the reserve and the regulations.

Although the ER was surrounded by Sunday sports fishers, there was no fishing observed in the ER. One sports fishing charter boat, white ~ 21 – 24’ long, came through Middle channel at high speed, heading towards Victoria.

There were Bigg’s Killer Whales (transients) in the area today and we watched as a large male, possibly T103, made his way from Church Island, through Race Passage and on towards Constance Bank, with a bevy of whale watching boats. Five of those boats also passed through the Ecological Reserve

A branded, male Steller’s Sealion was noted today, hauled out on South Islands. He was branded 603R, as a pup in July 2007, at Rogue Reef in southern Oregon. That makes him 8 years old this summer.

Steller's Sealion # 603R is an eight year old male branded in Oregon, near the California border.

Bald Eagles continue to attack the geese, the Black Oystercatchers continue to gang up on the Raven that may be up to some tricky business with their unsheltered ‘nests’ and the Pigeon Guillemots are spending a lot of time on the jetty and ashore, practicing landing, taking off and walking around. The Glaucous-winged gulls are mating which is quite an acrobatic feat of balance and the Northern Elephant Seal moult is progressing quite fast in the larger animals.

Population Explosion

During the early morning there were light winds from the north but it soon switched to west and blew 25 to 30 knots mid-morning. The wind dropped down to a lazy 5 to 10 from the west and swung through south to east and back again, during the rest of the afternoon. The barometer rose steadily all day and even though there were showers early on, the day ended in glorious sunshine with a 10 knot wind from the west, southwest. The forecast is for the wind to turn to east and bring more showers.

Five whale watching vessels were observed within the Ecological Reserve and they were all very respectful of the speed regulations although several were as close as 20-30 meters from the shoreline of Great Race. Two kayakers were noted in the Ecological Reserve in the late afternoon. Several halibut sports fishermen fished just outside the conservation area closed to fishing, respecting the boundary of the closed fishing area.

Casual, ecological observations were made in the inter-tidal at 0.9m and above today in the shelfing area just east of the derrick on the north side of Great Race. A widespread settlement event has occurred recently and juvenile barnacles (<1mm) carpet the mid- to upper inter-tidal area including any unoccupied rock and even occupied shells of sessile organisms like big, old California Mussels.

This population explosion will provide food for many whelks and opportunists and emphasizes incredible competition for space here in the intertidal. The more ephemeral algae of the high inter-tidal are starting to bleach out including some of the higher Porphyra spp or Pyropia spp (nori) and a small red that may be Rhodymenia sp. The following community of intertidal organisms in addition to those list above, were noted (in no particular order) in the area examined.

There were also at least four limpet species, several species of periwinkles, coralline algae, red algal turf and red crust.

Today there were 30 visitors. Catrin brought her first year biology students for a field trip and they were divided up into three working groups of eight students each. Erich from Victoria came with the group. Two volunteers from the College accompanied the group and Courtney drove them all out and back in Second Nature (six trips in total). Earlier I picked up Alex in the Race Rocks Whaler who is staying on. he was very helpful with all the landings, loadings and embarkations.

Other than working with all three groups of students which was a real treat, other chores were routine today. Some students, especially biology and marine science students really benefit from exposure to such a biodiverse and productive site as Race Rocks. Most students enjoyed the visit, many observed species they had never seen before and some even collected extensive data for next years individual investigations.
