May 26

It was another steady, west by southwest day, blowing 15 to 20 knots, from morning to night and clearing out the clouds for a glorious afternoon and evening. There was just enough marine haze on the horizon to make a great sunset. This morning barometer gradually rose to 1016 hPA and then started a slow decline after noon ending up at 1014hPA just before 8:00 PM. The forecast is calling for strong westerlies to continue with a mix of sun and cloud.

Only four whale watching boats were observed in the Ecological Reserve today and everyone was on their best behaviour.

Ecological happenings were subtle today. More sealions are hauling out on Great Race including a few very chunky Stellers bulls. The California Sealions seem to putting the call out for others within hearing range to come and bark in concert. There are more birds mating wherever you look, the Canada Geese goslings are growing incredibly fast and the bull kelp is now forming a broad canopy even on the high tide. The gull bolus contents are shifting to more ‘forage fish’ bone content from the earlier strong bias toward chiton plates and the adults are feeding each other in practice for parenthood?

The Bald Eagles continue to fly in and scare all the gulls, geese and oystercatchers and it looked like they caught something today, but I am not sure what..

Chris and Courtney brought Second Nature out in the afternoon with two visitors from Scotland, (an alumna and her husband), and the two relief eco-guardians Guy and Christine who will be here for the summer. Chris, Courtney and Guy delivered diesel for the generator, using the derrick, barrels, a drum dolly and a fair bit of sweat. It looked scary to me but they pulled it off with aplomb and Chris said it is easier, safer and less risky than the old method, so that is really great.

My chores today were routine. I am going to post this now and update it with photos later in case the Internet goes down again in between. Must run and shut down the generator.

 

 

Marine Mammal Hotspot.

As predicted, the west-southwest winds continued today with velocities of 15 – 20 knots. The first half of the day was cloudy and fog threatened but the sun eventually prevailed. Because of the late start, accumulated daily solar radiation was only half of yesterday’s value.

The barometer hovered between 1013 and 1024 hPa, rising in the morning and falling again, in the afternoon. The forecast is for more of the same with the addition of a 30% chance of showers tomorrow.

There were at least 15 visits to the Ecological Reserve by whale watching boats today and probably more as I wasn’t looking every second. Two sports fishing boats sped through the Reserve while most of the whale watching boats followed the rules, slowing on approach and in Reserve, steering well clear of marine mammals, using the middle of Middle Channel, and drifting with the current, or at least going with it.

The reason for all of the whale watching activity was of course biological activity in the area. Race Rocks and environs was a marine mammal hotspot today with at least seven species. At one point there was a Minke Whale very close to the Ecological Reserve boundary just to the east of Great Race and at the same time a large, adult Humpback could be seen ~ 1 nm south of Rosedale Reef travelling east. Once when I looked out at Humpback, it had six vessels pacing it.

Next on the horizon, there were two groups of Killer Whales, both apparently Biggs or Transient (aka mammal eating) Killer Whales. One group appeared to be made up of ~ 3 adult males and the other group looked like females, calves and one smaller bull. The last mentioned group shot out on the ebb tide to the west through Race Passage with a trail of whale watching boats trying to keep up.

The Long Weekend.

Fog followed an overcast dawn and was repetitively beaten back by sunshine throughout the day. While the sun was out, it was intense (900 Watts/meter2), but fog lingered just to the west and Beechey Head was repeatedly obscured as the fog came and went. Eventually in early evening, pushed by the west-southwest wind, the fog rolled back in and enveloped Race Rocks. For most of the day day the wind blew west a fairly steady, 10 – 15 knots. The fog wind was more intense though, pushing 25 – 30 knots. The barometer went up a bit in the morning and then, after noon it dropped by a little more than it had gone up, ending up at ~1014 hPa and falling. The forecast is for a strong wind warning, (more westerlies), mainly sunny, with a few clouds.

No whale watching vessels were observed in the Ecological Reserve today. Several private, sportsfishing boats went through at a respectful speed and they were not fishing in reserve. One rental boat from Pedder Bay Marina was fishing in the Rockfish Conservation Area on both the east and on the west side of the houses. The people seemed to know that they were not supposed to be there and were playing a bit of hide and seek. Two couples were all fishing for and keeping rockfish in the Rockfish Conservation Area (RCA). Whether or not they exceeded the limit for outside RCA (1 rockfish per day) is open for speculation.

Two large male Killer Whales were spotted travelling east, along the north edge of the Ecological Reserve in Race Passage. As is often the case with Bigg’s Killer Whales, they seemed to be evasive, perhaps exhaling underwater. They were spotted again near nNorth Rocks and then skirted around to the south. From their behavious, it is likely that these were Bigg’s Killer Whales.

It takes a lot less energy to play when suspended in water.

The Northern Elephant Seals have been sticking very close to shore during their swims, preferring the shallow sub-tidal in the bull kelp fringes. The young males who love to play fight when they are hauled out continue their sparring activity in the water. I wonder if the Bigg’s Killer Whales could hear them?

Another new (to me) Northern Elephant Seals showed up today, well tagged with #9836 on the right and #9807 on the left. All four tags looked really new as did the seal. The smallest one ashore since I arrived in March, it had almost completed its’ moult and the skin was looking too big for it, so I venture to guees that it has been hauling out on Middle Rock moulting for a while and came over to Great Race because of all the bustling seal activity here.

This small animal is starting to look like her skin is a bit too big for her.

Both routine chores and seasonal maintenance were accomplished today. The grated, aluminum ramp on the jetty was repaired and trouble-shooting completed on the Whaler’s electrical system. There were no new visitors today.

Camera 5 back on line

After a period of being down, our IT specialist at Lester Pearson College,  Maxim  Wieser has been able to restore Camera 5 to operation.  Now the only problem is keeping it clean, and that is no easy task as seagulls like to hover above it…….cam5a

Greener Pastures (Covering May 11 & 12)

The wind blew west 20 – 25 knots until early afternoon on Monday when it slowed, came in from the southwest and cleared out the cold, wet clouds. For the rest of the day, it stayed partially overcast with sunny breaks and the forecasted call for more of the same, with showers was spot on. The dropping barometer leveled out a bit Tuesday and the prediction is for continuing strong westerlies, which blew all day 10 – 20 knots. Wednesday looks like a wet one.

Monday morning  was blustery  and bristling with police and military activity on the water, all around but not in the Ecological Reserve. Only two whale watching boats were noted in Reserve on Monday.Tuesday only one whale watching vessel was noted in Reserve. There was a Pedder Bay rental with independent researchers counting seals and sealions. Tuesday, Second Nature arrived with a large contingent of support staff, maintenance, IT and volunteers. Tuesday was punctuated by military blasting.

The elephant seals were on the move today and yesterday. After a dawn swim, Monday, only half the animals moved back behind the boathouse, where most of them have been sleeping for the last couple of weeks. The grass where they were lying, behind the boat house, is a fried brown colour. Although it looks dead, it will probably come back after a couple of weeks like the other crushed and cooked parts.

Seven animals, including two females who started the move, found fresh, green grass right outside my basement door. Tuesday was a repeat performance except that we were also graced by the presence of a very large male. It was a short visit and I was too busy to measure him but he was massive.

There were at total of 17 Northern Elephant Seals on Great Race Monday and at least two individuals here Sunday that were gone Monday. My guess is that there is exchange with the group hauling out on Middle Rocks and that was reinforced by the big visitor here today.

California Sealions started hauling out on the jetty today.

Some the gull pairs are getting quite good at their acrobatic feats of reproduction which involve the male standing, balanced on the females back.

Chores were minimized Monday due to an injury. There were no visitors Monday and six staff/volunteers Tuesday. The men moved a tidy tank across the island, Max fixed camera 5 and did some trouble-shooting and Courtney started training Guy.

 

More Than Radical Moult?

The east-northeast breezes that came with dawn, soon turned to west-southwest and became light winds by early afternoon. The early morning sky was quite hazy with smoke and “marine air”. A gale warning was in effect today and when the wind picked up to 20 knots in the late afternoon it cleared the haze temporarily, but then the “marine air” (with brown tinges) thickened and started to feel like a chill fog. The wind rose to 30 knots in the evening. The rising barometer leveled off for the afternoon then started dropping. The usual forecast continues.

 

I was surprised that a vessel of this size would use Middle Channel but she was well driven, slowly and carefully.

I was surprised that a vessel of this size would use Middle Channel but she was well driven, slowly and carefully.

It was a busy Saturday on the water and a parade of whale watching boats came through the Ecological Reserve to observe the usual cast of characters. A total of 20  commercial whale watching boat visits to the Ecological Reserve were observed today.  All but one of these vessels took their time while in the ER, minimizing potential impact on wildlife by driving slowly.Their passengers probably saw more that way. The one vessel that seemed a bit pressed, just had a momentary lapse and dropped his speed after clearing away from a sports fisher also observing.

Some of the vessels that came through Middle Passage seemed a mite large. One of the smaller, open vessels took the passage between Great Race and South Islands. There really isn’t much room in there and there are a lot of animals in the water and on the rocks of that narrow passageway. Not a good practice, nor is it really following the regulations or guidelines.

A few sports fishers came through the reserve to have a look at the animals and they also drove slowly and kept their distance. There were several rental boats in the Ecological Reserve today, all but one behaving. One rental packed with people sped right through the “rockpile”, not slowing for wind, current or Ecological Reserve. A dive charter from Ogden Point dove a couple of sites in the Ecological Reserve today, All very calm and professional.

The Northern Elephant Seal moult continues with most animals sleeping in a pile and making the trek to the water at least once a day for a soak and a swim.

The little female A114 came back today. She is in terrible shape with many open sores, continuously bleeding on the ventral side, which leaves trail of blood and she is often shivering or maybe it is trembling? She smells really awful, perhaps not long for this world, or is it just a super radical moult? I think it is pathological.

This little female, A114/ A473, has serious skin problems. More than just a radical moult.

Where the skin folds above the foreflippers, the folds have become open cracks.

Out of the ~20 animals observed closely, there are three with the ‘more than a radical moult look’; two females and a male. Earlier, I confused A114 and the “Psoriasis Sister”. I now know they are very different animals of different size. A114, the smallest is definitely the worst for wear with her gouges, deep cracks and ventral bleeding. All of these animals keep to themselves (separately) and have not been seen sleeping in the skin to skin “pile” with the healthy looking, very social seals.

Pairs of Pigeon Guillemots, Black Oystercatchers and Glaucous-winged gulls are mating. Three pairs of Canada Geese are walking their goslings, successful broods of eight, six, four and three. There seem to still be two pairs who have not nested and the other six pairs are still incubating.

There were no visitors and chores were routine.

 

 

 

 

 

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.

Misleading information in recent STANTEC report on Whales.

Also see the APRIL 23 post with graphs on Whale Observations from Race Rocks 2009-2014.
I believe that the increasing frequency in recent years in the number of humpback whales observed in the area which will be affected by increased tanker traffic from the Kinder Morgan/ TMX project has not been taken into account In the Consultant’s report issued today
Quantitative Assessment of Increased Potential for Marine Mammal-Vessel Interactions from the Trans Mountain Expansion Project TRANS MOUNTAIN PIPELINE ULC TRANS MOUNTAIN EXPANSION PROJECT -Prepared by: Stantec Consulting Ltd. 500 – 4730 Kingsway Burnaby, BC, V5H 0C6 Ph.: (604) 436-3014, 

Quoted from the report :
“While the BC CSN data includes numerous opportunistic sightings of humpback whales in the study area over the course of the last four decades, the majority of the Marine RSA is generally not recognized as a humpback whale hotspot, although the western extent just overlaps with the eastern-most extent of humpback whale critical habitat –(Fisheries and Oceans Canada 2013a). As such, and since actual humpback whale density values for the Marine RSA (Regional Study Area) do not exist, this species was assigned a density according to the lowest density observed for humpback whales during the surveys reported on in Best and Halpin (2011) elsewhere in BC ((Williams and Thomas 2007) did not observe any humpback whales during their summer 2004 survey in this area) This value corresponds to roughly 10 whales distributed across the majority of the Marine RSA

——As a result, humpback whales were assigned a proportion of time in the study area of 0.17 (i.e., two months of the year) based on the largest concentration of sightings from the BC CSN data (British Columbia Cetacean Sightings Network 2013)”

Here is a good example, in my opinion,  of how a decision having long term implications regarding the welfare of a species recovering from near extinction may be completely misdirected if based only on a consultants interpretation of officially published scientific resources which can quickly become dated.

2009-2014 Whale Observations from Race Rocks

Lester Pearson College has employed the Ecoguardians at Race Rocks Ecological Reserve since 1997. One of the benefits of this is in having observers on site 24 hours on this archipelago in the Strait of Juan de Fuca. A great amount of citizen science is achieved as they record in their logs the events such as whale sightings of the area.

In the past year I have been working as an intervenor for the Board of Friends of Ecological Reserves to try to question and advise  the National Energy Board and the Kinder Morgan Corporation on the problems of increasing the traffic of oil tankers from the Westridge terminal through the Strait of Juan de Fuca. The area of potential impact from chronic and catastrophic oil spills puts at risk the ecological integrity of  up to 17 of our Marine Ecological Reserves around southern Vancouver Island. In our submission I was able to draw upon the records from the Race Rocks Ecoguardian’s logs to demonstrate the increase in the incidence of whales in this area. A recent report of the Department of Fisheries (Sufficiency Review of the Information on Effects  of Underwater Noise and  the Potential for Ship Strikes from Marine Shipping on Marine Mammals  in the Facilities Application for the Trans Mountain Expansion Project )has criticized the Environmental assessment done by Trans Mountain as being ineffective to take account of the increasing potential of Impact on the large whales such as humpbacks and the underwater noise which will masking of the ability of whales to communicate and get food.

I put together the following graphs to show the increase in the number of days per month that whales were observed from Race Rocks:

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.
