Today was spent tidying around the island, chainsawing logs and chopping firewood. I gave the gulls and sea lions a wide berth as I moved around the paths.

650 L of diesel was delivered this afternoon.

Here are a few photos from today:

August 24 – Weekly Census

Wind: W 4-19 knots
Sea State: calm in morning, rippled in afternoon
Visibility: 10-15 NM
Sky: overcast, then clear from mid morning onwards
Temperature: 13-15 °C
Atmospheric CO2: 412.21 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Here are the numbers from today’s census:
30 steller sea lions
121 california sea lions
1 sea otter
167 harbour seals
1 bald eagle
2 pelagic cormorants
742 california gulls
518 glaucous-winged gulls
169 gull chicks
4 black oystercatchers
14 pigeon guillemots
1 black turnstone
2 killdeer

I was excited to see the fluffy head of the sea otter this afternoon. This morning when doing the census count from the top of the tower, I scanned the kelp but couldn’t see the otter.

This afternoon, I gave TLC to the boat house, boat and boat dolly.

There was a steady stream of about two or three eco tour or pleasure boats per hour passing through the ecological reserve.

Here are some sights from around Race Rocks today:

August 23

Wind: W 2-19 knots
Sea State: calm in morning, rippled in afternoon
Visibility: 15 NM
Sky: clear, partly cloudy in evening
Temperature: 11-16 °C
Atmospheric CO2: 412.58 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

There were not a lot ecological happenings to note from today. The sea lions are continuing to grow in numbers in the main haul out spots on the southwest side of the main island, southeast side near the lighthouse, jetty area, and Middle Rock. Stay tuned for the weekly census tomorrow to get the official numbers to see how the population has grown since last week.

I have been keeping track of the two steller sea lions seen recently with flashers hooked to their mouths. I only saw one this morning near the jetty. I thought I saw one which was possibly the same one on Middle Rock, although I couldn’t get a good look at it because it was facing away.

I transferred diesel to the furnace tanks in each house, in the ongoing effort to get everything stocked up for the colder months.

There were a lot of eco tourism and pleasure boats in the area, taking advantage of the nice weather.

Here are two photos from today:

August 22 – More Flashers

Wind: W 9-12 knots
Sea State: calm in morning, rippled in afternoon
Visibility: 10-15 NM
Sky: clear
Temperature: 13-15 °C
Atmospheric CO2: 412.45 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It rained heavily overnight, giving the windows and pathways a much needed cleaning of the built up bird poop. I have been able to collect run off water from the downspouts on the main house and energy building, which can be used in the pressure washer to clean paths and exterior walls.

This morning, two steller sea lions were spotted with flashers hooked to the left sides of their mouths. One appears to be the sea lion spotted over the past few days. The other has an identical flasher. The Marine Mammal Rescue Centre has been updated, as this makes three different stellers with flashers hooked to their mouths in a week and a half.

Here are a few photos from today:

August 21

Wind: every direction throughout the day 0-24 knots
Sea State: calm in morning, rippled in afternoon
Visibility: 0-10 NM
Sky: fog and patches of rain in morning to mid afternoon, partly cloudy in afternoon to evening
Temperature: 12-18 °C
Atmospheric CO2: 412.15 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The juvenile female elephant seal tagged V173 slid her way up the boat ramp this morning. She is looking healthy and well fed. She has visited several times over the past few weeks, as well as in the spring to moult and briefly in December. She was born last year on Drakes Beach, in Point Reyes National Seashore, in California. Researchers tagged her as a weaned pup on February 28, 2019.

I did some maintenance around the island: changed the oil in the backup generator, tidied paths with the trimmer to make it easier to move fuel and equipment with carts, cleaned the solar panels, washed windows on the main house, and pressure washed the stairs leading up to the door of the lighthouse to get rid of the slippery bird poop. Greg brought 800 litres of fresh water, which we pumped up from the jetty to the fresh water tank.

Here are two photos from today:

August 20 – Two Pods of Transient Orcas!

Wind: W at the beginning and end of day, NE mid morning to early afternoon, 4-18 knots
Sea State: calm
Visibility: 0-10 NM
Sky: fog in morning, clear in the middle of the day, overcast in afternoon, rain in evening
Temperature: 12-17 °C
Atmospheric CO2: 412.15 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

There was a lot marine mammal activity today. At 11:00, two pods of Bigg’s transient killer whales were in the ecological reserve. One pod appeared to have about six whales. The other pod appeared to have three. Both pods spent a lot of time around the South Islands. A nearby whale watching boat captain mentioned on the VHF radio that the orcas were two families most likely having some social time. They were probably having a good meal too. I didn’t see any hunting happening on the surface. Transients eat marine mammals like seals. I did see a lot of harbour seals not taking any chances, huddled together on nearby rocks and around the east bay beach, looking towards the areas where the orcas were swimming. The transients stayed around until at least 3:30.

See the photos below for views of the orcas and other sights from today:

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 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.
