Panting to Cool Down on Great Race

Posted on by

Westerly breezes of 15 to 20 knots kept the island comfortably cool today as the sun shone steadily. The overall tendency of the barometer, was to slowly fall today ending up at 1012 hPA., as the sun set. The forecast is for continued strong westerlies and clear skies.

Twenty-one visits to Ecological Reserve by whale watching boats were observed today and there were probably more that I missed while doing other chores. Again most of the operators were great but there are a few who speed and a few who go too close. Several sport fishing boats and one rental were also seen transiting the Reserve.

The large Humpback whale affectionately known as Big Momma by the whale watchers did a complete circuit of Race Rocks today without actually entering the Reserve itself. While travelling through Race Passage she was accompanied by five to ten whale watching boats and was never alone.

Chunk and Floyd, the two large male Northern Elephant Seals spent a lot of time “fighting’ in the water today and that was also draw for the whale watching boats. Chunk definitely has the advantage over Floyd both in terms of size and personality. Floyd had quite a few fresh bleeding scars this evening and Chunk was doing quite a bit of perhaps, triumphant bellowing.

The lone male, sea otter that hangs out in the Middle Channel kelp bed directly opposite the eco-guardians’ house was also a draw today. The sea otter was viewed close up, by just about every vessel and he seemed completely unfazed by all the attention. Whale watching vessel congestion in the Ecological Reserve continues to be potentially problematic. Also dangerous for the little rental boats that like to follow close behind some of the bigger whale watching boats.

Whale watching vessel operators are good at avoiding each other in narrow channels.

Gull incubation is happening right now and one of the interesting behaviours observed is thermoregulation by panting. Today there panting gulls everywhere.

Gulls can keep their eggs at just the right temperature by evaporative cooling through panting.

Of note, the majority of the Canada Geese have left the island after a rash of Bald Eagle attacks. They were observed practicing the swim across to Middle Island with the goslings and were gone by June 10th, leaving three pairs of adults and their 10 collective goslings.

There were no visitors today and chores were routine.

Double-Billing (Thursday-Friday)

Posted on by

Thursday was a howler. The wind started early and blew ferociously all day. Although it developed into a classic westerly, it actually started out from the west-northwest, which is closer to the direction running down the outside coast of Vancouver Island (NW). Most of the day, it was westerly from 30 – 40 knots and late in the afternoon there gusts over 40 knots. The fog that formed early on the Port Angeles side of the Strait was blown away early and the sky stayed clear until just after sunset when clouds became visible in the west. The barometer has been rising since Wednesday and the forecast is for continued gale warnings and mix of sun and cloud.

 

It really calmed down on Friday. The westerlies with a touch of southwest, continued but at moderate speeds of 15 -25 knots. Although there were clouds to the west early in the morning, they evaporated quickly and it was full on sunshine all day. The barometer is dropping from a high of 1020 hPa and the forecast is for strong winds and mostly clear skies.

There were no whale-watching boats, or sport fishers on Thursday, as the weather and sea conditions were just too wild. Friday was a totally different story with 16 whale-watching vessels observed, visiting the Ecological Reserve. Some vessels made multiple visits.

There was a lot of whale activity within and around the Ecological Reserve. Both a Minke Whale and a large Humpback were feeding just to the southeast and south respectively and three different pods of Killer Whales moved through the area in the afternoon and evening, including small group of Bigg’s Killer Whales (Transients), two pods of southern residents ( J-pod and L-pod according to the whale-watching boats). One of the SRKW pods came right into the Reserve within fifty meters of South Rock, heading east. There were two large adult males, one small calf and about 15 individuals all together. Another ~ 20 individuals were travelling in the same direction about one mile to south, at the same time. It appeared as though the two groups met up and mingled to the east of Race Rocks. Time for the sockeye to be running.

Other ecological happenings are progressing as has been reported on for the past few weeks. I started a Glaucous-winged Gull nest survey Thursday and finished surveying about one third of the island. On Friday the female Northern Elephant Seal # 5866’s tags were noted. Chunk and Floyd have been peacefully moulting, sleeping and travelling up and down the ramp for several swims a day (more like lolly-gagging in the water).

Thursdays are animal census day. It is worth noting that the winter resident bird species such as Black Turnstone, Harlequin Duck and many species of gulls that nest elsewhere are gone now and so are the transitory migrant shorebirds and other migrants that stop off briefly or for a while. The sealions are at their lowest number which is expected since they too should be on or heading towards their breeding grounds. Census results follow.

Northern Elephant Seals 10 (including 5 on Great Race)

Harbour Seals 218

California Sealions 5

Northern or Stellers Sealions 2

River Otter 1

Sea Otter 1

Canada Geese 24 (= 10 goslings + 14 adults) (many appear to have swum away)

Pelagic Cormorants 3

Double Crested Cormorants 5

Bald Eagles 2 (1 adult, 1 sub-adult)

Black Oystercatchers 10 (5 nesting pairs all incubating)

Kildeer 2

Pigeon Guillemots 110

Caspian Terns 2

Glaucous-winged Gulls total 424 (402 adults in nesting areas; 22 sub-adults in roosting/resting area). Most gulls are incubating now, although some are still getting started.

There were no visitors on Thursday and two visitors Friday, who did a retreat in the science house. They came and went in Second Nature with Chris.

Chores and maintenance were routine today and I am glad to report that I am able to wash windows again.

 

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.

Floyd may look like a large lump but when I saw him being frisky today I was amazed at how fast he could hustle that bulk across the lawn after a female.

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.

Green and purple sea urchins with a small orange nudibranch to their left (Rostanga pulchra) that usually lives on the red sponge Ophlitasponge.

 

Today was large animal census day and the results are as follows:

Northern Elephant Seals 34 (including 15 on Great Race)

Harbour Seals 179

California Sea lions 17 (includes brand U792)

Misleading information in recent STANTEC report on Whales.

Posted on by

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

Posted on by

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:

New DFO Report highly critical of Kinder Morgan /TMX environmental assessment on Whales

Posted on by

The recentlly released DFO report:
(See Full PDF) 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 was very critical of the Trans Mountain Expansion Project Application documents. The Conclusion of the report is concerned with Vessel strikes on Whales and the overall impact of noise from increased Project-related traffic.  Included below are the conclusions of the report.

Conclusions

There are deficiencies in both the assessment of potential effects resulting from ships strikes and exposure to underwater noise in the Trans Mountain Expansion Project Application documents.

There is insufficient information and analysis provided with which to assess ship strike risk in the Marine RSA from either existing or Project-related traffic. Ship strike is a threat of conservation concern, particularly for baleen whales such as Fin Whales, Humpback Whales and other baleen whales (Gregr et al. 2006). If shipping intensity increases as projected in Section 4.4 in the Marine RSA and the Strait of Georgia and Juan de Fuca Strait as a whole, the significance of this threat to cetacean populations that occupy the region will increase.

Incidence of recovered whale carcasses is not considered to be an adequate measure of the frequency of ship strikes. No information is provided about the speed and maneuverability of Project-related ships or the distribution of whales in relation to the shipping lanes. Analyses that consider the statistical probability of ship-whale encounters and the risk of collisions are considered appropriate methodologies to assess this potential effect.

The JASCO MONM model, as it has been applied by the Proponent, is not adequate to assess the overall impact of noise from increased Project-related traffic. Although state-of-the-art acoustic modelling has been used to model the noise propagation associated with a single Project-related tanker in the Marine RSA, only four locations were chosen to represent the Marine RSA; therefore, the assessment does not adequately represent the noise exposure for the entire time a marine mammal would be in the RSA. The assessment represents only Project-related tanker traffic and not the current noise environment or the potential increase due to Project-related traffic. Finally, the method used to assess the significance of impacts from the modelled noise level contours resulting from a single Project-related tanker and tug on indicator cetacean and pinniped species is qualitative and the lack of an appropriate assessment framework reduces DFO’s ability to evaluate the assessment.

Humpback

Barometer continued to drop during the day to below 1005 hPa by nighttime. The wind was10 knots N in the morning and picked up to gusts over 30 knots in the evening.  There have been growing swells coming in from the North East.

Observed two river otters around the boardwalk in the morning and several eagles hunting and feeding in the reserve today.  Before dusk there was a lone humpback whale between West rock and Church rock.  Also around dusk I saw a sea otter off the south end of the island swimming on its back eating something off its chest.

Cleared the boat ramp twice of debris, harvested driftwood, cut and stacked firewood.

Peregrine, Eagles and Wind

The wind gusts reached 39 knots from the west this morning.  The general wind trend throughout the day was between 11 and 32 knots from the west, with slight fluctuations to the north and south.  The barometer generally went down from 1001 hPa to 997 hPa, with a few dips upwards as the sun broke through the clouds.

The approaching Arctic blast of cold weather will bring a chance that the thermometer might drop from 7oC to below 0oC tonight for the first time in a while.  Heating coils and warm thoughts have been deployed around the buildings to prevent pipes from freezing.

There was one whale watching boat seen in the reserve at 12:30.  A couple boats gathered to view humpback whales to the east of the reserve in the mid afternoon.

There were a couple of bald eagles around for most of the day, one adult and one juvenile. At 10:00 in the morning, a peregrine falcon was chasing after the juvenile eagle over the north of Great Race and Middle Channel.  The size difference of the eagle and peregrine took me by surprise.  I had never seen the much smaller peregrine next to a bald eagle. This might be the same peregrine that Pam Birley has seen over the past week.  It had dark chest feathers, which indicates it is a juvenile peregrine falcon.

The desalinator worked hard today to make about 800 litres of fresh water.  With a maximum output of 1.5 litres per minute, the desalinator is a very energy intensive way to create water.  Although, when the water is heated and added to a mix of leaves, spices and herbs, it makes great tea.  A necessity for Race Rocks.

Weekly Census

Posted on by

The wind varied in velocity and direction throughout the day.  Fog settled in overnight as the wind blew between 15-25 knots from the southwest.  In the daylight hours, the wind blew from the south and west between 7-32 knots.  The barometer dropped slightly from 1008 hPa to 1004 hPa.  It was overcast with patches of sun and rain throughout the day. The temperature reached a high of 12.8oC at noon.

There was one whale watching boat seen in the reserve, in the mid afternoon.

I saw humpback whales (Megaptera novaeangliae) twice today, both times from the kitchen window.  The whales were surfacing just south of Great Race Rocks, within the boundaries of the Ecological Reserve.  At 9:30am, I saw two humpbacks blow, surface and dive westward.  At 3:20pm, I saw one humpback surface and dive eastward.  I am not positive if they were different whales, so I counted them as two in the census.

Two branded steller sea lions were seen seen today.  76Y was a pup in 2002 when it was branded in St. George Reef, California.  443Y was branded in 2013, when it was a pup at Rogue Reef, Oregon.
