March 16 – Camera, Crane and Coruscating Sun

Posted on by

Sunny
Wind: 5-16 knots from the SW and S in the early morning, NE until 17:00, SE for a few hours and calm after 20:00
Air Temperature: Low 6.6°C, High 10.3°C
Ocean Temperature: 8.9°C

The underwater camera is back up and running, after a few weeks offline. The power issue has been solved. Algae on the dome around the camera is partially obstructing the view, but it will be cleaned soon by divers from the college.

This afternoon, there were two low flying aircraft: a floatplane and a Search and Rescue Helicopter.

Three fishing boats passed through the ecological reserve today. One boat spent an hour fishing within the Rockfish Conservation Area, which is prohibited by the Department of Fisheries and Oceans (DFO). The Rockfish Conservation Area is within the 40m depth contour of Great Race Rocks and Rosedale Reef, marked by the green buoy to the southeast of Great Race Rocks.

The crane needs to be run and serviced once a month. Today, it was used to lift a 12m log from the jetty beach to the boardwalk, where it will be chopped into firewood. In hindsight, it would have made it less challenging to cut the log in half while it was on the beach. Although, 6m sections wouldn’t have been as much fun to manoeuvre with the crane.

During the low tide in the afternoon, there was a large number of harbour seals and sea lions hauled out on the rocks. Two branded steller sea lions were seen on the South Islands. Both sea lions were branded as pups at Rogue Reef, Oregon. 524R was branded in 2007. 365Y was branded in 2013.

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.

March 13 – Finding Nests and Making Water

Cloudy with sunny breaks
Wind: 2-14 knots, NE in morning SE in afternoon
Air temperature: Low 8.7°C, High 11.3°C
Ocean temperature: 9.0°C

A bazaar of 27 pigeon guillemots spent the morning on the wharf, nearby rocks and occasionally gathering in the water to float through Middle Channel. They appeared to be checking out nesting sites on the rocks between the wharf and helicopter pad. They like nesting in the crevices and under the blasted rocks on the northwest side of Great Race.

The visiting students helped unroll the fire hoses to pump salt water into the cistern, which is underground between the lighthouse and the Ecoguardian’s house. The water from the cistern is pumped through the desalinator. This afternoon, the desalinator ran for eight hours, producing about 700 litres of fresh water.

There were three eco tour boats and two recreational boats in the ecological reserve today.

March 12 – Sunny Census Thursday

Posted on by

Sunny
Wind: 0-13 knots SW in the morning, NE from mid morning to afternoon and SW in the evening
Air Temperature: Low 9.9°C, High 13.2°C
Ocean Temperature: 9.0°C

Three Pearson students came to Race Rocks this morning. Karen, Sunny and Hanne joined Martin, who has been here since Monday.

The students did some work this afternoon: sweeping all 99 steps of the lighthouse and continuing the process of stowing the chopped wood in all the nooks and crannies of the buildings, to be used next winter to heat the main house.

There was DND blasting happening in the morning and early afternoon on Bentinck Island, less than 1km away from the ecological reserve.

Today’s high temperature of 13.2°C, as measured at the ground weather station, was the highest recorded since 2006, when the weather station was installed. A high of 14°C was recorded by the instruments at the top of the lighthouse.

Three eco tour boats visited the reserve. One boat came very close to a group of sea lions swimming and others hauled out on the South Islands.

The low tide of 1.1m at 13:52, exposed lots of species from the low tide zone into the air. The shore and tidal pools were full of life: mussels, barnacles, limpets and lots of other flora and fauna of the sea. The oystercatchers and shore birds were having a feast.

There were no small birds perching birds seen today. There are usually a few fox, sparrows, savannah sparrows and occasionally juncos and robins zipping around the island.

Here are the results from today’s Megafauna Census:
Elephant Seal: 1
Steller Sea Lion: 54
California Sea Lion: 43
Harbour Seal: 52
Bald Eagle: 9
Great Blue Heron: 1
Crow: 1
Oystercatcher: 4
Double Crested Cormorant: 12

A great blue heron hung out on northeast side of Great Race for the afternoon. The oystercatchers are travelling around in pairs and are quite vocal. The gulls have spread themselves out around the island as they start to find nesting sites. Chunk returned to Great Race during the night. He spent the day resting against a boulder and the rock below the helicopter pad. The female elephant seal is relaxing in the same spots as yesterday, to the west of the main house.

One eco tour boat and one recreational boat visited the reserve today.

Cold, Sea Lion Brands and Beautiful Sunset

Posted on by

The wind blew from the northeast, between 15 and 25 knots.  The barometer rose in the morning from 1024 hPa and then dropped to 1020 hPa.  The visibility was unlimited, with great views of Mt. Baker and many other wonders of the Salish Sea.  The temperature reached a high of 2oC as I am writing this at 21:00.

The dive boat from Ogden Point visited at 11:00.  The group was diving around Middle Rock.

I was going to leave on the Race Rocks boat this morning for a short trip into Pedder Bay to drop off garbage and pick up gas.  A lot of garbage is being swept onto the shores of the ecological reserve.  I thought I had a good window to get away from the jetty. Although, the northeasterly swell started to pick up just as I was putting the boat in the water.  The waves were too high as they rolled into the jetty, so I changed my plans and raised the boat back into the boat house.

Two branded sea lions were spotted today.  See the photos and captions below for 359Y and 975Y.  In November there were 20 different brands spotted around Race Rocks. Many of those california and steller sea lions had never been spotted before at Race Rocks.

I collected depth soundings from all the tanks around campus for the month end report. 475L of diesel was used over the past month to power the generator and heat the houses. Last year in November, 737L of diesel was used.  The reduction of diesel use by a third  this year has come from increased power output from the solar array as well as the wood stove, which was installed last winter in the Ecoguardian’s House.  There are lots more changes being made to transition to more sustainable power sources.  Stay tuned to this blog to read about them as they are introduced.

Snow Day!

Posted on by

The wind was howling up to 38 knots from the north northeast last night, bringing with it a low of -2oC and a couple centimetres of snow.  The temperature stayed just below 0oC for the rest of the day.  The barometer rose from 999 hPa to 1022 hPa throughout the day, making for a bluebird sky.  During the daylight hours, the wind continued to blow from the north northeast between 10 and 20 knots.

There was one whale watching boat seen in the reserve in the mid afternoon.  Six divers from Ogden Point were exploring the undersea world of the reserve in the late morning.

The snow didn’t seem to faze the animals.  The sea lions barked just as loud and the bald eagles tormented the gulls just as much.  Some of the snow melted from the sun.  There is still ice on some of the paths and rocks, as well as a light dusting of snow on the grass and in the places that were shaded by buildings and rocks.

Other than taking photos of snow, the tasks of the day included: running the desalinator, topping up the batteries with the generator, deconstructing the old washroom in the basement of the Marine Science Centre to accommodate the new composting toilet (it’s almost finished), fixing the wheelbarrow, testing the salinity and temperature of the water, and doing a load of laundry.

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.

Here are the results of the weekly census:

Humpback Whale: 2
Steller Sea Lion: 244
California Sea Lion: 216
Harbour Seal: 39
Northern Elephant Seal: 4
Bald Eagle: 5 (2 adults, 3 juveniles)
Canada Goose: 18

Birds and Sea Lion Brands

The wind was calm, not rising above 10 knots.  It blew from the northeast, swinging around to the south in the middle of the day, and settling on the east at night.  The barometer dropped from 1020 hPa to 1009 hPa, with a few short rises throughout the day.  The temperature reached a high of 10.8oC, at the ground station.

There was one whale watching boat seen in the reserve, just before sunset.

Pam Birley, the dedicated webcam viewer from the UK, spotted a peregrine falcon again this morning.  She was able to capture a photo of the peregrine from Camera 1, see below.  Pam thinks it’s a young one, because it has dark brown chest feathers.

I wasn’t able to spot the peregrine, but I saw two branded steller sea lions.  See the photos below of brands 205Y and 405Y.  The steller sea lion branded 405Y was born in 2013, at Rogue Reef, Oregon.  The steller sea lion branded 205Y is a female born in 2004 at St. George’s Reef, California.   The sea lion is well known to Pat Gearin, from the NOAA. Pat emailed me with some details about the sea lion: “She is an unusual animal because she has not returned to CA to have her pups but instead has settled at Carroll Island, WA where she has had at least two pups over the last 4 years.  I think the animal next to her in your first photo may be her juvenile which is still nursing.  Steller’s sometimes nurse their pups for over 2 years.”

Bald Eagles and Sea Lion Bones

The wind blew from the south, switching around to the east and north, by the mid afternoon.  The velocity of the wind hovered between 9 to 15 knots, during the daylight hours.  The barometer dropped from 1027 hPa to 1018 hPa.  The sky was overcast, with rain in the afternoon.  The temperature was 8oC for most of the day, dropping from 10oC yesterday.

There were no boats seen in the reserve today.

This morning, nine bald eagles were in reserve at one time:  four adults and five juvenile. They made at least one kill of a gull, just below the high point of the island, northwest of camera 5.

During a beachcombing exploration this afternoon, I found a partially decomposed sea lion carcass.  It appeared to be a steller sea lion, based on the appearance of the fur and flippers.  It was near where I had found other sea lion bones a few weeks ago.  The bones had been mostly cleaned by gulls and insects.  It looked fairly recent, because the fur was still intact and attached to several parts of the skeleton.
