August 19 – Fog

Wind: W 4-23 knots
Sea State: rippled
Visibility: 0-15 NM
Sky: fog in morning, clear in late morning, partly cloudy in afternoon, then light rain in evening
Temperature: 12-17 °C
Atmospheric CO2: 412.58 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The fog began to roll in after sunset yesterday. In the early hours of the morning just before 3:00, the fog got thick enough for the sensor part way up the tower to trigger the fog signal. Three high pitch blasts sounded every minute until 11:20, then the fog gave way to a clear sky.

The steller sea lion with the flasher from yesterday still has it hooked to its mouth and is still on Middle Rock, hanging out with a bunch of other sea lions. I spotted it through the partial fog this morning, but wasn’t able to get a good photo. This afternoon, it was facing away from the main island.

Greg came out in the late afternoon to deliver diesel. We are filling the various storage tanks around the island for the furnaces and generator, in anticipation for the cooler and darker months ahead. There will be more fuel delivered over the coming days, taking advantage of the calm seas.

Other maintenance tasks included trimming the plants growing over parts of the paths, cleaning the solar panels and using the chainsaw to buck up more firewood. I finally cut up a 15 metre log that I saw wash up in a winter storm. It was propped up on rocks in the East Bay.

August 18 -More Sea Lions

Wind: W 15-29 knots
Sea State: up to 0.5m chop
Visibility: 10-15 NM
Sky: clear in morning, partly cloudy beginning in early afternoon
Temperature: 14-19 °C
Atmospheric CO2: 412.58 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The groups of steller and california sea lions around the main island and on Middle Rocks have all increased in number. There were two noteworthy sea lions today. In the afternoon, I noticed a lone steller sea lion near the end of the jetty. It had a white and red flasher (fishing lure) hooked to its mouth. Unfortunately, this is a sight that is occasionally seen here. Just last week there was another steller sea lion with a pink and yellow flasher. That sea lion (branded O-19) has not been spotted since. The flashers could have had a fish hooked on the end, which was eaten by the sea lion, or the lure could have appeared to the sea lion to be a fish. The sea lion this afternoon, left the jetty when a large boat went by. A few minutes later, it appeared on Middle Rock where a group of about thirty sea lions were hauled out. I will keep an eye on this sea lion. If it stays around for a few days, it could be a candidate for a rescue from the Marine Mammal Rescue Centre.

When I spotted the sea lion with the flasher haul out on Middle Rock, I noticed a steller sea lion branded 975R. The R means it was branded at Rogue Reef, in Oregon. This animal has been seen here before. See Ecoguardian Anne Stewart’s post from April 6, 2015. The steller was branded as a pup in 2011.

There were about twenty-five eco tour boats that passed through the Ecological Reserve today, some of them repeats. They appeared to be viewing the hauled out sea lions, harbour seals and the floating in the kelp sea otter.

August 17 – Weekly Census

Wind: W 19 to 33 knots
Sea State: up to 1m chop
Visibility: 10-15 NM
Sky: clear
Temperature: 15-21 °C
Atmospheric CO2: 412.54 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Last night after the sunset, a lightning show began. There was at least one flash visible per minute when I was watching from about 21:00 to 22:00.  According to CBC News, there were 1,600 lightning strikes overnight across BC’s South Coast: https://www.cbc.ca/news/canada/british-columbia/august-lightning-weather-bc-south-coast-1.5689195

Weekly census results observed today:
33 steller sea lions
45 california sea lions
1 sea otter
313 harbour seals
1 adult bald eagle
1 Canada goose
3 pelagic cormorants
1256 gulls (approximately 2/3 glaucous-winged gulls and 1/3 california gulls)
4 black oystercatchers
53 pigeon guillemots
42 black turnstones
1 american pipit

There were many ecotour boats passing through the Ecological Reserve today and only a few fishing boats visible in the distance.

 

August 16 – Returning Sea Lions

Wind: from NE in morning, SE in afternoon, W in evening – between 2 to16 knots
Sea State: calm in morning and rippled in afternoon
Visibility: 15 NM
Sky: clear
Temperature: 16-25 °C
Atmospheric CO2: 412.54 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

While I have only provided the conditions for today, I did step onto the Rock just after noon yesterday. It’s great to be back, having spent the whole winter and the first few weeks of spring here. I will be here for the next two and a half weeks, 100 days shorter than my last stint.

I feel very fortunate to be a part of the amazing team of Pearson students, alumni, staff, volunteers, donors and researchers who keep this Ecological Reserve going.

I spent yesterday afternoon and evening reacquainting myself with this wonderful place, practicing how to avoid disturbing the young gulls, who blend in well with the rocks as they like to hide beside the paths and in plants.

This weekend, there have been a lot of boats (pleasure craft and eco tour boats) taking advantage of the nice weather. The only visitor to the island, other than me, was Greg, who drove me out here from Pearson and brought back Mara and Kai.

In the previous log post, on August 13, a branded sea lion with an attached flasher (fishing lure) was mentioned. The steller sea lion is branded O-19. Bryan Wright, the Marine Mammal Biometrician/Project Leader at the Oregon Department of Fish and Wildlife, gave us an update on the history of the stellar sea lion:

He was captured and branded by us (ODFW, along with WDFW) at Bonneville Dam on the Columbia River on February 2, 2012.  We don’t know his exact age but he was probably 5-7 years old at the time of capture, making him 12-15 now.  He then wasn’t seen again until July 21, 2016, at Tatoosh Island off the tip of the Olympic Peninsula in Washington.  He was then next seen back at Bonneville Dam from August-November, 2019.

Bryan also passed along an interesting article that was just published called “California Sea Lion (Zalophus Californianus) Monitoring In The Lower Columbia River, 1997–2018” (Brown et al 2020). Click here to read the abstract of the article.

April 13 and 14 – End of Shift

Wind: yesterday variable 2-28 knots, today W 7-38 knots
Sea State: yesterday calm, today rippled in morning and up to 1 m chop in evening
Visibility: both days 15 NM
Sky: both days clear
Temperature: yesterday 7-13 °C, today 8-11 °C
Atmospheric CO2: 415.81 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Today is my last full day on the island before the shift changeover. Tomorrow morning, Mara and Kai will arrive to take over as Ecoguardians. They were here last year from May to September.

I spent the past two days finishing up some tasks around the island and cleaning. I also took time to walk around the island and get a look at all of the incredible species, land and shoreline that make up this ecological reserve.

There were no boats in the ecological reserve.

See the photos below for some views from around the island.

April 11 and 12 – Weekly Census

Wind: yesterday W-S 0-32 knots, today W-SE 2-17 knots
Sea State: both days calm
Visibility: yesterday 10-15 NM, today 15 NM
Sky: yesterday partly cloudy then clear from mid morning, today clear
Temperature: yesterday 8-14 °C, today 7-14 °C
Atmospheric CO2: 416.33 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The lawn in front of the house got busier this morning with nine elephant seals, two more than yesterday. A tenth seal, the pup, was near the jetty. The two new arrivals have green tags on their tail flippers. One is a male tagged C887. The other is a juvenile tagged G512 on the right flipper and E779 on the right. I will update the information on age and past sightings when I hear back from the researchers. The green tags signify the elephant seals were tagged at Año Nuevo, south of San Francisco.

[UPDATED April 13: I heard back from Dr. Patrick Robinson, the researcher from Año Nuevo Reserve. The elephant seal with green tags E779 and G512 was tagged as a pup in February 2019, where he was born at Año Nuevo. This is the first time the male juvenile has been spotted outside of Año Nuevo, where he was last seen as a weaner in March, 2019. The elephant seal with the green tag C887 is a juvenile male that was born at Año Nuevo in February 2017. He has been seen at Race Rocks in the month of December in 2017, 2018 and 2019.]

There was one boat seen in the ecological reserve on each of the past two days, a pleasure boat yesterday and a sailboat today.

Census results observed this afternoon at low tide:
10 elephant seals (1 female pup, 1 female juvenile, 1 juvenile, 2 sub adult males, 5 female adults)
16 steller sea lions
91 california sea lions
1 sea otter
72 harbour seals
5 bald eagles (2 juveniles, 3 adults)
16 Canada geese
1 black brant goose
99 gulls (mostly thayer’s)
17 pelagic cormorants
4 brandt’s cormorants
5 double-crested cormorants
6 black oystercatchers
24 pigeon guillemots
7 harlequin ducks
2 surfbirds
5 black turnstones

April 9 and 10

Wind: yesterday W 0-26 knots, today W 11-38 knots
Sea State: both days calm in am and up to 1 m chop in pm
Visibility: yesterday 15 NM, today 0-15 NM
Sky: yesterday clear, today fog from 7:00-8:00 then clear
Temperature: yesterday 7-9 °C, today 7-10 °C
Atmospheric CO2: 417.85 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The youngest elephant seal pup came back ashore, on the east side of the island. She is easy to identify from the scar below her right eye. She spent the evening and night on the southeast side of the house, where she spent several weeks in February and March once she weaned from her mother. Today she had moved around to haul out on the boat ramp and swim in the sheltered water by the jetty.

A new sub adult male elephant seal has joined the other elephant seals. He is a bit smaller than the other sub adult male that joined the last week.

Yesterday there were two visitors, Guy and Corey, in the college boat Second Nature. There were no other boats in the ecological reserve.

The fog signal sounded for an hour this morning, before the sky cleared. It hasn’t sounded for almost two months. The fog signal is (3) 60 s, which means three blasts sound and repeat every minute. The more detailed version is blast 2 s; sil. 3 s; blast 2 s; sil. 3 s; blast 2 s; sil. 48 s.

April 7 and 8

Wind: yesterday W 0-34 knots, today E in am SE in pm 0-16 knots
Sea State: both days calm
Visibility: yesterday 10-15 NM, today 15 NM
Sky: yesterday partly cloudy in morning, clear onwards, today clear
Temperature: yesterday 8-11 °C, today 6-13 °C
Atmospheric CO2: 415.60 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

A sea otter spent most of yesterday afternoon in the South Channel between South Islands and South Seal Rocks. It ate clams, cleaned itself and rested on the rocks. When it dove underwater to grab some more food, I approached to get a closer view from an indent in rocks on South Seal Rocks. See the 16 second video below.

The last elephant seal pup appears to have left today. She was swimming in the jetty bay for most of the day. When I went out in the boat this afternoon, she was floating by the rocks to the north of the jetty bay. When I returned, she wasn’t there anymore or on the land. All three surviving pups left the island within a week of being three months old. The two others haven’t returned. Presumably, they are off feeding themselves after teaching themselves to swim over the past two months, since they weaned from their mothers.

I moved four wheelbarrows of the remainder of this winter’s supply of wood from the cupboards beside the Energy Building to the basement of the house. That wood should last for any cool or damp days of the spring or fall. I fixed some loose boards on the winch deck and boardwalk. Over the winter, the sea lions were rough on that deck.

A single blast was heard yesterday morning just after 11:00, coming from the demolition training area at Rocky Point.

One pleasure boat was seen in the ecological reserve this evening. The Race Rocks station boat was out this afternoon for a quick trip to Pearson College to pick up groceries.

April 5 and 6 – Orcas

Wind: yesterday variable 0-17 knots, today variable 0-22 knots
Sea State: both days rippled
Visibility: both days 15 NM
Sky: yesterday partly cloudy, today clear
Temperature: both days 5-10 °C
Atmospheric CO2: 416.03 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday morning, I noticed a pod of at least six orcas on the western edge of the ecological reserve. They swam east through Middle Channel, passing just north of the main island. What a treat it was for me to watch them from the front porch. See the photos below.

The older of the two female pups has been gone for the whole day. She left the island at some point early this morning. It’s been 14 days since the oldest of the three surviving pups left the island. Perhaps the pup who left today is following the strict schedule, as she is 14 day younger than the male pup who left 14 days ago.

Today, there were three boats in the ecological reserve: two pleasure craft and one local whale watching boat with two people on board.
