March 23 – Ships and Sea Lions

Overcast and light rain, sun breaks in the evening
Wind: NE 3-14 knots, switching to W 5-11 in the evening
Air Temperature: Low 7.2°C, High 9.4°C
Ocean Temperature: 8.8°C

Today was filled with the usual chores of cleaning rust of things, collecting wood, stacking firewood, running the generator, creating fresh water with the desalinator, measuring the salinity and temperature of the ocean water and looking out for the species of the ecological reserve.

This afternoon, a large aircraft carrier passed within 4km of the ecological reserve. The USS John C Stennis is a nuclear powered super carrier, the largest type of aircraft carrier, measuring 333mx77m and weighing over 100,000 tonnes.

See the photos below of the ships that passed to the south of Race Rocks, close to where the sea lions swim, hunt and haul out.

Upon looking at the photo of the aircraft carrier, I noticed a sea lion in the foreground that is branded 26Y. This steller sea lion was born at Rogue Reef, Oregon in 2002.

More Wind, Waves and Clear Skies

The wind blew between 23 to 37 knots from the east for most of the day.  A swell with 1m waves continued from the east.  The barometer dropped from 1027 to 1019 hPa.  The visibility was unlimited, with clear skies.

There weren’t any boats seen in the reserve today.

Only one elephant seal was seen today by the jetty, where upwards of 16 have been spotted there in the last few weeks.

I received some information from Pat Gearin at NOAA about three of the branded steller sea lions seen within the past several days.  All three were branded as pups in Rogue Reef, Oregon.  I have reposted the photos below.


833R was branded in July 2009 as a pup when he weighed 32kg and was 110cm long.  Since then he has been seen in June 2011 at Patrick’s Point, CA; and June 2014 in Tatoosh West, WA.
946R was branded in July 2011 as a pup when she weighed 29.9kg and was 108cm long.  Since then she has been seen in December 2011 at Pachena, BC; June through September 2012 in Rogue Reef, OR; and in July 2013 at Jagged Island, WA.
872R was branded in July 2011 as a pup when she weighed 30.8kg and was 107cm long.  Since then she has been seen 16 times between Pachena, BC and Tatoosh West, WA.

The desalinator ran today for 8.5 hours, creating about 600L of fresh water.  The solar panels were producing 1.2kw of electricity this afternoon.  The windows on the Ecoguardian’s house were cleaned inside and out.  More cleaning and installation was done in the basements of the two houses to ready the spaces for the composting drums and collection units for the new composting toilets.

Standing Waves

The fine weather continued today with light outflow winds and clear skies. The barometric pressure rose to almost 1020 hPa by mid–morning and then started to slowly slide back down. This pattern is forecast again for tomorrow.

I counted 32 tour boats in the reserve today and may have a missed a few as I was busy. I talked to the Garry Fletcher, Ecological Reserve Guardian and learned a great deal.
There were Biggs Killer Whales out to the west again so many of the boats broke up their trips coming or going with a stop at Race Rocks. A few recreational fishers went through at low speed but no poaching today. The only transgression noted was a Grady White speeding. The man with the white hat and red rubber boat was back but stayed just outside the line.

Just before sunset, an enormous aircraft carrier headed past and on out to sea. Ahead of it was a container ship and behind a schooner. The volume of goods and people coming and going in Juan de Fuca Strait is really amazing and it all passes by Race Rocks. Port Metro Vancouver alone trades $184 billion in goods and then there is Seattle, Victoria, Bellingham, Spokane etc..

Corrections to yesterday’s log: 1. There are still at least two Pigeon Guillemots feeding young. 2. I forgot to count in the four Canada Geese that are here daily. 3. I got a good look at the Black Turnstones from the tower today and counted 23.

I did some research today, starting with reading a few papers on Steller’s and California Sea Lions and looking at a paper on Glaucous-winged Gull chick mortality. I talked to Race Rocks Ecological Reserve Guardian, Garry Fletcher, learning a great deal. I started a Glaucous-winged gull survey today and found 30 so far. It is important to get this done before it starts getting too damp.

The practical side of the day involved more cleaning and starting a perimeter fence for the science house. The doors of the house are no match for a 2200 pound sea lion.
I watched the creation of large, breaking standing waves today, right in front of the house/jetty. The tide was flooding in and there was no wind so there must have been some ebb pushing out against it. Pretty spectacular for a few minutes then it calmed down.
