The Sun is Shining

Posted on by

The wind dissipated over night. After 8:00am, the wind was calm, only blowing 3 to 5 knots from the southwest. The barometer rose to a high of 1030 hPa at noon, then slowly fell to about 1027 hPa. The temperature reached a high of 12.6oC

There were five visitors that came from Pearson College, on the boat Second Nature. Courtney brought two folks from Cullen Water to install the repaired desalinator pump. Tristan and Robin, volunteers from Wales, helped carry the many boxes that contain the new composting toilets. Each house will have the toilets installed soon.

There were two whale watching boats in the reserve this afternoon. Four halibut fishing boats were spotted to the west of the reserve for most of the afternoon. Many large boats passed within a few kilometres of the southern boundary of the reserve, including a submarine, tankers and HMCS Edmonton.

The harbour seals were difficult to spot for the census yesterday. With the sun and warm weather today, they were hauled out on the rocks to catch some rays. 32 were seen today, compared with only 7 yesterday.

Three branded sea lions were seen on South Seal Rocks, just south of the engine room. I have let Pat Gearin at NOAA know about the sightings and he will let me know where else they have been.

There are updates about the two branded sea lions spotted yesterday.

Pat Gearin wrote to me with the details about the Steller that was branded 966R as a pup at Rogue Reef, Oregon in July 2011.  It is a male and so far we have 9 resights from this individual, all from BC.  In 2011, he was sighted at Pachena Point once, and in 2012 he was sighted at Carmanah 8 times.

Matthew Tennis wrote that U596 was branded on August 15, 2014 in Astoria. At that time he weighed ~193 kg. He was seen in Astoria for a few days following the branding and again in the middle of October. This is the first resight for this animal outside of Astoria. They have high site fidelity and being a relatively young animal, it is very possible he will be seen at Race Rocks for years to come.

Maintenance tasks were performed today: moving propane tanks, pressure washing the algae and bird poop off the exterior of the houses, dismantling the old toilets, picking up garbage that has washed ashore and running generator and new and improved desalinator.

Getting Ready for the Census

Posted on by

The northeasterly wind picked up to 23 knots in the middle of day, producing a choppy swell with frequent whitecaps.  Mixed with the inflowing tide, the standing waves off the end of the jetty became quite large.  The barometer dropped steadily.  There was a low cloud cover with a few scattered showers.

The Juan De Fuca Warrior from Ogden Point visited twice with two groups of four divers.

I prepared for tomorrow’s census by practicing my species identification and counting.  The numbers will be double checked tomorrow and revealed on the log.  The sea lions are proving difficult to count, due to their large cuddle puddles.  Where does one sea lion begin and the other end?

I checked the underwater camera twice today.  Both times there was a sea lion swimming across the screen just as it loaded, but I wasn’t fast enough to click the button to save the image.

Up on land, the california sea lion that was camped out by the desalinator bunker for the past two and a half days decided to move this evening.  It must have got tired of waiting for the new desalinator pump.  Don’t worry, it should be here by Friday.  Just before sunset, the sea lion waddled on all four flippers eastward over the salt water cistern and down the rocks to the water.  Taking many breaks along the 50m overland journey, it collapsed and exhaled large lungfuls of steamy breath.

Sea Lion Thermoregulation

Posted on by

The barometer rose steadily throughout the day as a moderate westerly breeze whipped across the reserve. The clouds parted mid morning to bring an afternoon of sun and a high of 13.1 oC.

The solar panels weren’t the only things soaking up the sun’s rays. Sea lions were floating in small groups with one or all four flippers exposed to the air, using thermoregulation to their advantage. The sun warms the seal’s flippers, which are poorly insulated, then the warmed blood is pumped throughout their body.

One whale watching boat was seen in the reserve, after they spotted humpback whales surfacing a few kilometres to the east of the Race Rocks.

Courtney visited on the Second Nature to give a quick lesson on some of the mechanical systems on the island.

Maintenance tasks were performed today: running the generator, cleaning the solar panels, tracking down equipment and parts, figuring out how to use the equipment, vacuuming, flag care, and sweeping the paths.

Pinnipeds galore

Posted on by

There was a moderate breeze for most of the day.  The barometer dropped slightly throughout the day. There was a low cloud cover and occasional light rain.

There was only one whale watching boat seen in the reserve today.

Two juvenile bald eagles took the rocky perch on the South Islands that was occupied by the adult bald yesterday morning.  Occasionally one of the eagles would assert its authority over the gulls by flying around Great Race and sending the thousands of gulls skyward into a panic.

The pinnipeds are still occupying the reserve in large numbers.  Perhaps wanting solitude from the cacophony of sea lion barking, a lone california sea lion parked itself in the middle of the island for the whole day.

This afternoon, a group of five harlequin ducks were hanging out by the kelp beds to the west of the jetty.

It looks like I'm not the only one excited about the arrival of the new desalinator pump. This California sea lion spent the whole day in the middle of the island.

It looks like someone else is also excited about the arrival of the new desalinator pump. This california sea lion spent the whole day in the middle of the island near the desalinator bunker.

A Good Day for the Birds

As the sun rose, the wind and sea were calm. The wind picked up throughout the morning to become a moderate breeze with light rain and choppy seas during the afternoon. The barometer rose during the morning and dropped slightly in the afternoon, levelling out at 1014 hPa in the evening.

Eight boats were seen visiting the ecological reserve: 4 whale watching boats, 1 pleasure craft, 2 visits from SCUBA divers at Ogden Point Dive Centre and one boat from Pearson College to pick up Rikka, a student who was visiting for the last four days.

Maintenance tasks were performed today: chopping driftwood for the fire, daily seawater salinity test, running the generator and cleaning the houses.

Two crows were making their rounds on the reserve throughout the day. A juvenile bald eagle flew around Great Race at 0800, landing on Turbine Rock. An adult bald eagle landed on the high point of the South Islands at 1345 and took watch for an hour.

Clear Skies

As the daylight broke, the fog began to burn off near the entrance of Pedder Bay and to the west of Race Rocks. The wind rose slightly throughout the day to a medium breeze of 11 knots in the evening. Clear skies prevailed through the day as the barometer rose slightly.

Maintenance tasks were performed throughout the day, giving me a chance to spend lots of time outside: painting, tidying, sweeping, cleaning the solar panels, and topping up the batteries with the generator.

There were ten boats in the seen in the reserve. Several whale watching boats passed by. The Juan De Fuce Warrior from Ogden Point Dive Centre spent a few hours with two groups of divers. Two boats from Royal Canadian Marine Search and Rescue (RCMSAR) Station in Sooke passed through Middle Channel at noon. A sailboat went against the current through Middle Channel at 15:30.

The wind was blowing northeast this morning 20 – 25 knots, it dropped mid-afternoon for about an hour and then swung to the west. The west came on strong in the late afternoon and blew over 25 before settling down to 15 -20 knots. The barometer, which has been falling all day, started climbing at 19:00 and the forecast for tomorrow is looking better with light winds forecast.
There were only two whale watching vessels spotted in the Ecological Reserve today. There were no other vessels other than Second Nature dropping off Nick Townley the new eco-guardian and Pearson College student Riikka who is here to finish her project week.
The results of the census are as follows:
Steller Sealion 447

California Sealion 433

Northern Elephant Seal 16

Harbour Seal 17

Canada Goose 24

Greater White-fronted Goose 1

Double-crested Cormorant 324

Pelagic Cormorant 29

Most of the work today was packing, cleaning,  and training Nick in preparation for departure tomorrow.

Mega-fauna Draw

It was another north-northeasterly day on Race Rocks. There was even some sunshine during the late morning and early afternoon but it clouded over for the latter part of the day. The barometer is dropping again and the forecast is for windy, cloudy and wet.

The weather did not deter the hardy whale watchers and nine tour vessels were observed in the Ecological Reserve.

Meno and WW

Killer Whales, Humpback Whales, Steller and California Sealions, Northern Elephant Seals and Harbour Seals were also observed from the Ecological Reserve creating the draw for tourists.

Sealions lounging

Most of my day was tied up with supporting the water technician’s visit to repair the desalinator, briefing fending off Elephant Seals, stowing fire hoses and entering/organizing data. During my tower trip I was able to see all of these species and noted three new brands on Steller’s Sealions on MiddleRock.

It was another day of mixed weather at Race Rocks. Gentle breezes less than five knots, tended north to northeast all day. While the sea surface appeared calm, there was a big sea running that caused spectacular waves on the west side of the islands. The barometer rose until noon and then started to slip back down. Although it looks like rain coming on the horizon now, it was a fairly dry day while apparently pouring down over on the American side.

In spite of many Humpback Whales in sight from Great Race, the season must be winding down, as there were only five whale-watching boats observed within the Ecological Reserve and only one sports fisher stopped by for a look at the seals and sealions.

The interesting, new (to me), Steller’s Sealion brand of the day comes from almost as far away as yesterday’s George Island animal whose branding location was indicated by the ‘Y.’ Today’s ‘T’ stands for Marmot Island which is just off the southeast end of Kodiak Island. So both of these animals are from the western Alaskan Stellers Sealion population, west of 140 degrees west. The western population is considered to be endangered due to its inexplicably, declining numbers. How interesting that these guys are hanging out here, where there is a lots of food right now, far from home.

This branded Stellers Sealion was born on Marmot Island just off Kodiak Island, Alaska. He was branded as a pup, July 4, 2010.

Second Nature, with Courtney at the helm, brought out the chimney specialists who cleaned and inspected the chimneys in both houses. A young Frenchman from Lille who is volunteering at Pearson College came along as well. I did some more trouble-shooting with the desalinator and called an expert for help. I strung the fire-hoses and fired up the Briggs & Stratton and pumped seawater into the cistern. The hoses are getting a nice fresh water rinse over-night.

Spot the Mian.

Weather was happening all around Race Rocks today but it was pretty nice here. There was a significant swell, which is nice to watch, unless you want to launch a boat. Across the Strait, on the American side, it was really pouring on the Olympic Peninsula especially in the Elwah Valley. Here, clouds came and went, it rained a little, it shone a bit and the barometer was actually up and steady after yesterday’s low. Forecast is for more of the same.

There were only two whale-watching boats observed in the Ecological Reserve today and one was a “new” catamaran vessel that I have not seen before, called “4-Ever Wild”.

Juan de Fuca Warrior spent the day with a crew diving in the Ecological Reserve most of the day again today. I forgot to mention that yesterday there were three happy kayakers enjoying a paddle in the Ecological Reserve and unwittingly getting a little too close to the sealions.

Some of the photos of sealions taken from the tower actually show Elephant Seals too. Can you spot the Elephant Seals in these two photos?

I spent quite a bit of time troubleshooting web-cams, “watertight boxes”, power and ethernet lines, not very successfully, but maybe tomorrow. I changed both of the cartridge filters on the desalinator today. I worked on further organization of the brand, tag and entanglement data for both species of sealion and got some new photos of brands.

The Steller Sealion in the background Euju 299Y was I believe, tagged on St. George Island in the Bering Sea. The Y refers to that location which is close to 5,000 kilometers away from Race Rocks. Looking for confirmation of this amazing voyage.
