Fourth Elephant Seal Pup

Sea State: yesterday rippled, today up to 2 m swell
Visibility: 10-15 NM

The elephant seal harem has a new addition. In the early afternoon yesterday, another pup was born. Since December 29, there have been four births, which is a record for an elephant seal pupping season on Race Rocks. Unfortunately, only about half of pups tend to survive, due to aggression from other elephant seals, learning to nurse, weaning and predation.

There were three visitors yesterday to do some maintenance on the desalinator: Greg, Warren and Cole. Warren and Cole got a once in lifetime opportunity to see the elephant seal birth. They were walking from the desalinator building to the main house, when Warren noticed the pregnant seal had more flippers than usual. Within less than a minute, the female slid up a grassy incline and out popped the pup. It seems like she used gravity to her advantage. All the humans went into the house, so as not to disturb the seals. The new mother vocalized with the pup and the pup wriggled around. The pup appeared larger than the other three at birth. Perhaps it is a male, as male pups tend to be larger than female pups.

What followed next was difficult to watch. Just ten minutes after the pup was born, it was attacked by another mother. The elephant seal mother that gave birth to the third pup, tossed around and bit the new pup, drawing blood between the eyes and on the head. After a few attacks and several minutes passing, the new mother appeared to intervene and put itself between the aggressive seal and her pup. The mother that gave birth to the second pup also appeared to intervene, by approaching and also putting itself in the middle. Out of the five adults in the harem, the third mother was the only one that showed aggression towards the new pup.

Today, Alex and Greg visited for a couple hours in the middle of the day to problem solve a power issue that presented itself yesterday. It’s great to have a lot of people on land supporting the various off grid systems on Race Rocks.

Here are a few photos from the past two days of the flora and fauna on Race Rocks:

Bald Eagle Convocation

Wind: yesterday 5-33 knots SE to N, today 8-20 knots NNE
Sea State: yesterday up to 2 m swell, today rippled
Visibility: 10-15 NM
Sky: both days mixture of sun and clouds

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.

Weekly Census

Posted on by

Wind: yesterday 8-33 knots S to W, today 2-24 knots W to NE
Sea State: rippled
Visibility: 10-15 NM
Sky: both days mixture of sun and clouds
Temperature: yesterday 3 to 8 °C, today 2 to 4 °C
Atmospheric CO2: 412.63 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

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.

Results of the weekly megafauna and bird census:
10 elephant seals (4 females, 4 males, 2 pups)
200 steller sea lions
242 california sea lions
107 harbour seals
8 bald eagles (7 adult, 1 juvenile)
56 brandt’s cormorants
124 pelagic cormorants
43 double-crested cormorants
178 Thayer’s gulls
12 harlequin ducks
9 black turnstones
1 snow bunting

A Third Elephant Seal Pup is Born

Posted on by

Overnight a third elephant seal pup was born to the mother who arrived at Race Rocks on Monday, January 6. On the lawn in front of the house, there are now three pups hanging out with their mothers, a pregnant female and the alpha male.

More Snow and Elephant Seals

Wind: yesterday 10-29 knots N, today 16-63 knots N switching to E in the afternoon
Sea State: yesterday rippled, today up to 3 m waves from E
Visibility: yesterday and today 1-10 NM
Sky: both days fog, blowing snow, cloudy and patches of sun
Temperature: yesterday -1 to -4 °C, today -4 to 3 °C
Atmospheric CO2: 412.38 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The snow has continued to fall, creating large snowdrifts against buildings, paths and rocks. I have enjoyed watching the elephant seals move through the snow and appear to play in it. The snowdrifts have changed my routes around the island, finding the path of least resistance that doesn’t disturb the ground or engulf me into a metre of snow or a hidden puddle. It’s not all fun and games here, there have also been some fights amongst the elephant seals. The beta males have been chasing each other around the island and sinking their teeth into each other. There are once again four adult males on the island. The alpha male continues to be with the pups and females. A new pregnant female elephant seal arrived yesterday morning as I was waiting for Greg to arrive in the boat with a food delivery. She made her way up the boat ramp to the centre of the island with the others. That brings the current elephant seal count to ten. Perhaps two more pups will arrive soon.

Since the snow and strong winds came, the sea lions are still mostly in the water, floating in large groups. Today, a few california sea lions huddled on the jetty. A smaller number of birds have been seen in the ecological reserve. Stay tuned for the post in two days with the results of the weekly census.

Sea Otter Visit and Snow Day

Posted on by

Wind: yesterday 3-53 knots W, today 9-34 knots N
Sea State: yesterday 2 m waves from W, today up to 1 m waves from N
Visibility: yesterday 2 to 10 NM, today 1 to 2 NM
Sky: yesterday sunny with cloudy patches, today fog and snow
Temperature: yesterday 7 to -1 °C, today -1 to -4 °C with windchill as low as -14 °C
Atmospheric CO2: 413.15 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday brought many gifts from the sun: rainbows, warmth and solar power for the batteries. In the afternoon, I spotted an unusual sight for this time of year. A sea otter was being tossed around in the waves near the jetty. I grabbed the camera and did my best to capture some photos as it swam around the northeast side of the island, got out briefly on the rocks near the house, then swam back to the waves of the north side, before it floated northeast past the east side of the North Rocks. The wind was over 40 knots, which made it hard to hold the camera steady and take photos. I managed to get a few photos (see below) that show a slightly blurry sea otter in action.

Last night, the temperature dipped below O °C. I prepared the buildings from getting too cold by turning on heat in the evening. Throughout the night, the fog horn sounded and the snow accumulated. Judging by the snow on the relatively sheltered ground mounted solar panels, there was about 8 cm of snow overnight and into the early afternoon. On the rest of the island, the tracks of sea lions, birds and slide marks of elephant seals showed the few movements of a quiet island. A smaller than usual group of gulls and cormorants were hunkered down on the southwest side of the island. Most of the sea lions were rafting in the water, which was observed this afternoon at 7.7 °C, much warmer than the -4 °C air temperature.

A video of the two beta male elephant seals fighting at the base of the lighthouse. They move very fast when they are motivated. After they disappeared behind the tower, they chased each other around the island and into the water by the jetty, causing a stampede of some nearby sea lions.

Another Elephant Seal Birth

Posted on by

Wind: yesterday 2-19 knots NE, today 1-46 knots NE shifting to W
Sea State: yesterday 3 m waves from NE, today 2 m waves from W
Visibility: 10 NM
Sky: both days overcast with patches of sun and rain
Temperature: 6-8 °C
Atmospheric CO2: 413.54 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday morning in the rain, I started pressure washing the slime covered stairs up to the door of the lighthouse. They were getting a bit treacherous on a wet and windy day. A second tank of water later, it was sunny and the 18 stairs as well as entryway were clean.

The past two nights have been louder than usual, with the elephant seal bellows and barks dominating the soundscape of waves, wind and sea lion barks. I was surprised to not see a new pup yesterday morning, after all the carrying on outside my windows all night. This morning, the light brought a delightful sight of a new pup. Once again, the eagles, black turnstones and gulls all made quick work of getting rid of the placenta and umbilical cord. The new mother had arrived at Race Rocks on January 3. The other pup looks huge compared the new pup. It’s amazing how much weight the older pup has gained in two weeks. The three females appeared to be at odds with each other for most of the day, with lots of bellowing and chomping. If the remaining pregnant female sticks to the pattern, she should give birth on Tuesday, which is nine days after she arrived on the island.

See the photos and videos below for some sights and sounds of the past two days.

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.

New Desalinator and New Adult Female Elephant Seal

Posted on by

Wind: 1-44 knots from NE yesterday to W this evening as the wind increased
Sea State: up to 3 m waves breaking on west side of the island
Visibility: 5-10 NM
Sky: overcast with rain and a few sunny patches today
Temperature: 6-11 °C
Atmospheric CO2: 413.70 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It was a flurry of activity on the island yesterday. A big change from having no human visitors for a week and a half. Greg brought seven other people on the boat Second Nature. Three volunteers from the college (Lawrence, Sandra and Vincent) came to help with some maintenance and clean up tasks. John and Mike, from Pacific Coast Fire Equipment, were here to do the yearly inspection of the fire extinguishers. Warren and Ric spent almost six hours doing the electrical and plumbing hook ups and tests of the new desalinator. The desalinator room is very cramped quarters with thick concrete walls and only a six foot high ceiling inside. As Race Rocks legend goes, the building was originally constructed as a fallout shelter for Cold War fears of nuclear attack. It apparently contained emergency supplies and two bunks for the lighthouse keeper and assistant keeper. There was no space for their families. In 1975, the building was converted to a water filtration plant.

The non-human activity was busy too, with the arrival of a new adult female elephant seal. She showed up soon after the boat, staying on the boat ramp for a while before coming up to the middle of the island. The alpha male chased her around, they barked a lot, then she settled in the grassy area between the desalinator shed and the flagpole, where she still is this evening. Now there are two suspected pregnant seals hanging out in the centre of the island near the mother, pup and alpha male. The two other males appear to be keeping their distance. One is near the jetty. The other is behind the house by the compost bins.

The desalinator is running well after a total of nine hours of use. This evening, I was delighted to see that it had pumped 600 L of fresh water into the tank. Combined with the 500 L from yesterday, the desalinator has produced more fresh water than has been used since my shift began on December 21. At this rate, the 4,500 L fresh water tank should be filled up in about a week. At that point, the desalinator will be run regularly, but for shorter amounts of time. It’s an energy intensive way to produce water which consists of a reverse osmosis system and secondary UV filter. The temporary method of getting fresh water while the desalinator was out of commission was also very energy intensive. It consisted of filling up a 1,000 fresh water tank at the college, boating it to the island, and pumping it up to the tank from the boat. The water usage is planned to increase a little bit in the near future, due to some much needed pressure washing of the exteriors of the buildings, to prevent them from being overtaken by algae.

Stormy Sunday

Posted on by

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!
