Atmospheric CO2: 414.73 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The past two days have been sunny, which means the animals and scenery are very photogenic.

There was lots of activity with the elephant seal harem today. Overnight, the third mother left the island, after nursing her pup for 24 days. Her pup is now a weaner, no longer getting milk from her mother. The three mothers whose pups survived all stayed for 24 days. The last female, who’s pup died 17 days ago, left late this morning. After the male mated with her, she was either trying to get away from him or was chased down the path and out into the water by the boat ramp. The alpha male left for about an hour, perhaps to get some food. He’s been on the island the longest of any of the elephant seals. He hasn’t eaten or left the island since before the first pup was born on December 29. That’s almost as long as I’ve been here without leaving, except I eat three meals a day. The female elephant seals will most likely return to Race Rocks exactly eleven months after they left, to give birth to another pup. Stay tuned to the Log next December and January for more pupping season drama.

Now that there are no adult female elephant seals left on Race Rocks, the alpha male’s role has changed from mating with the females, to protecting the three pups that remain. The alpha male is most likely father to all of them, as he was the alpha male last year as well.

Three beta male elephant seals are still on the island. One left for about 24 hours and returned this afternoon. When he slid up the ramp onto the island, he appeared to look around to see if any females were around. Then, he headed for the oldest pup and put his mouth around it. He didn’t appear to be trying to hurt it because no blood was drawn. The pup was screaming. The alpha male came over and scared away the beta male. For the afternoon and evening, the three pups were lying in the grass about 10 m away from each other. It will be interesting to see if the pups interact with each other, as they have in previous years.

Some other interesting sights were a sea otter, two black brant geese, and a very bright Venus visible in the western sky for a few hours after sunset for each of the past three nights.

There were no visitors to the island in the past two days. Four pleasure boats and three tour boats were seen in the ecological reserve.

Yesterday in the morning, three members of the Coast Guard came in a helicopter to do a routine check on some equipment on the island. The pilot phoned ahead to confirm the best place to land to try to avoid disturbing the animals. They landed on the helicopter pad. Sometimes they land on the grass at the base of the lighthouse. The Coast Guard guys were excited to see the elephant seals, which they hadn’t seen before. Usually when they fly into the lightstations up the coast, they see a lot of sea lions.

In the afternoon yesterday, three visitors from Pearson College came to the island to have a tour.

The only other boats that were seen in the ecological reserve were two tour boats this afternoon.

See the photos below for some views from the last two days.

Groundhog Day

Wind: yesterday 0-52 knots from S to W, today 0-18 knots from W to NE

This morning at sunrise, the elephant seals saw their shadows. As the lore goes for their fellow mammal the groundhog, that means six more weeks of winter. Hard to believe with the crocuses blooming and daffodils buds almost ready to burst. Although, there is snow in the forecast for tonight and tomorrow as the temperature drops to 0 °C.

There were no visitors to the island. Two eco tour boats were seen in the reserve this afternoon.

The Last Two Days of January

Wind: yesterday 5-20 knots from W to N, today 0-40 knots from N to W
Sea State: yesterday rippled, today calm in the morning and up to 1 m chop in the afternoon
Visibility: yesterday 0-15 NM, today 1-10 NM
Sky: yesterday fog then sun, today overcast and rain
Temperature: yesterday 7-9 °C, today 8-15 °C
Atmospheric CO2: 413.95 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It’s been a mix of weather over the past two days. Yesterday began with the fog signal beeping. Later in the morning, it got sunny. It was overcast this morning and afternoon. This evening, it got quite warm up to 15 °C and wet as a storm came in from the west.

There were six ecotour boats in the reserve over the past two days.

Three visitors were on the island today to work on the generator. For at least the next few days, the island is still on backup power. The web cameras and several other non essential systems on the island will remain off to conserve energy.

See the photos below for some views from the past two days:

The five day old elephant seal pup died overnight. It was in rough shape yesterday, possibly from attacks by other elephant seals. In the morning yesterday, it had fresh blood on its face and the alpha male was lying on the pup. Ravens and black turnstones have been pecking at the seals face occasionally for the past day.

The first elephant seal pup, which is fending for itself now as a weaner, was lying on its back today and I could tell it was a male. See the photo below. I am not sure the sex of the other pups, as I haven’t had a good look at their abdomens.

There were four visitors to the island yesterday. Jeff brought out Greg, Alex and Ric to work on the power issues. They hooked up a backup generator to help power the island and top up the batteries. In the afternoon, Greg brought a diesel delivery. Now, the island has a full supply of fuel for when the main generator gets fixed within the next few days. In the past few days, there has a been some power generated by solar energy, which has helped keep the batteries charged. Thanks to some IT help from Dan at the college, now there is internet for the weather systems and monitoring the power.

Four eco tour boats were in the reserve over the past two days.

For the past two mornings, there were many bald eagles in the ecological reserve. Today, 34 were seen perched on the West Rocks. Many more were catching fish and perched around the other islands. There appeared to be a lot of fish in the water, based on the swarms of gulls, cormorants and the feasting bald eagles.

This afternoon, two whale watching boats toured around the islands after watching the orcas in J pod, which were a few kilometres to the east and south of Race Rocks. Two other eco tour boats were seen in the ecological reserve over the past two days.

See the photos below for some sights from the past two days:

The snow is melting quickly, bringing puddles and mud.

The one day old elephant seal pup appears to be doing well and nursing a lot. It’s moving around and wiggling more than the other two did in their first couple days. The alpha male has been mating numerous times with the mother of the oldest pup.

In the early afternoon, I wandered around the island and peered out from the top of the tower to count the mammals and birds. There were some notable omissions in this fourth week of conducting the census. I didn’t see any geese today. The only sign of the honking birds was a lot of poop and tracks in the snow. I also did not see any black oystercatchers. It is possible the birds were scared off by the loud explosions. The Armed Forces were blasting yesterday and today at the Department of National Defence land-based demolition range on Bentinck Island, the closest land to Race Rocks. Directly after each blast, I witnessed sea lions stampeding into the water and birds taking flight. According to a 2017 article On the firing line with the navy, in the Victoria newspaper Times Colonist, the detonation range is used for training members of the Canadian Navy on how to use explosives. The navy has apparently made efforts to lessen the effects on marine life.

The last two days were spent doing some tasks around the island like running the desalinator, topping up the batteries with the generator and cleaning. Today, the sun in the morning and early afternoon was taken advantage of to get a great view of all the species for the weekly census and do a solar powered load of laundry.

The only visitor was Greg, who came out from the college this afternoon for an hour to show me how to use some equipment and remove a load garbage from the island. No other boats were seen in the ecological reserve.

I am glad to hear the Race Rocks live video cameras are being used by the grade 10 students in the Trek Outdoor Education Program, in Vancouver.

Stormy Sunday

Wind: 3-52 knots swinging around from SW yesterday in every direction to NW this evening
Sea State: up to 4 m waves
Visibility: 5-15 NM
Sky: overcast with rain and some sunny patches
Temperature: 5-8 °C
Atmospheric CO2: 413.65 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It has continued be very windy over the past two days, whipping up big waves from the west. Today, the wind reached a top speed of 54 knots or 100 km/h, which on the Beaufort Wind Scale is force 10, corresponding to a storm. The two higher forces on the scale are 11 (56-62 knots violent storm) and 12 (64-71 knots hurricane). See the photos and videos below for some windy and wavy views.

The wind cleared off the South Seal Rocks of its usual inhabitants of steller sea lions. They were floating in sea lion rafts and surfing the waves for most of the day. When the wind died down a bit in the late afternoon, I walked in the intertidal zone which at low tide connects the main island with the closest of the South Seal Rocks. I hadn’t been able to walk around there in the past two weeks I have been here, due to the hauled out sea lions. It was great to see the main island from the perspective of a sea lion. On my walk around, I found some intertidal trash, some of which has been there for a while. See the photos below for some of my finds.

On Monday, there is a planned visit from some electricians and technicians to do some work on the desalinator and energy system. These will be the first visitors in a week and a half. If all goes according to plan, the desalinator will be operational by early afternoon and pumping water into the tank.

During my time here in the past two weeks, I have used 800 L of water, according to the gauge on the water tank as well as the three consumed drinking water jugs. While I’m conscious of my water use, I still do all the normal tasks like cooking, drinking lots of tea, washing dishes, showering and doing laundry. As a comparison, the 2018 average day per capita water use in Vancouver, BC was 444 L. I’m doing all right!

Video: A panoramic view of the whole island and waves as seen from helicopter pad. The sound is quite loud due to the strong wind.

Video: Watching hail on the window from the comfort of inside the house, while the elephant seal neighbours brave the elements outside. It hailed three times today.

First Weekly Census of the Decade

Wind: 5-21 knots N-NE
Sea State: up to 3 m waves
Visibility: 10 NM
Sky: overcast with rain
Temperature:5-11 C
Atmospheric CO2: 412.64 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The weekly census was done today, because the rain yesterday created poor visibility. This morning, it was overcast but not raining, so there was a good birds-eye view from the top of the lighthouse. Some species that were not last week are a whimbrel, snow bunting and another female elephant seal. The new seal looks pregnant, so there might be another pup very soon. She has moved into a spot on the grass between the desalinator building and the flagpole. That’s a great place for me to watch from the house, which is just 20m away. Last year, the three pups were born between January 4 and January 20.

I heard back from a sea lion researcher about the branded sea lions that were seen on Race Rocks a two days ago. Bryan, from the Oregon Department of Fish and Wildlife, let me know about some of the places where the sea lions have been:
California X282: branded at Astoria (Oregon) on Feb 25, 2016 and resighted in Oregon and at San Miguel Island, CA in 2016-2017.
California X392: branded at Astoria on March 8, 2016 and resighted in Oregon and at San Miguel Island in 2016.
California X501: branded at Astoria on May 24, 2016 and resighted in Oregon fall of 2016.
California 1-59: braded at Bonneville Dam (near Portland, Oregon on the Columbia River)on May 19, 2015 and resighted at Astoria and Bonneville through 2017.

The only boats seen in the ecological reserve were two eco tour boats and two kayakers.
