Month End, and Bye for now!

Posted on by

Thanks for another fun term out here at Race rocks, Will be back in the fall!

Ecological Notes:

  • 2 adult female Elephant Seals
  • The Female that had the pup here this season is particularly vocal and bossy!

(video coming)

  • 2 Elephant Seal pups, 1 might be a small yearling
  • With the warmer weather, all the Elephant Seals enjoy their daily dip in the water.

(video coming)

  • As usual, the Geese are very protective of their nests

  • But the “baby” Elephant seal seems to take great pleasure in harassing the gees at their nests

  • Orca only observed passing the reserve once in the last week (but from other reports, they may have passed by unnoticed or early in the morning)

Visitors:

  • 1 volunteer came out to help Richard with projects

  • 2 sets of students came out for orientation and tasks assignments, they also enjoyed some mini presentations from the Eco-Guardian
  • Richard  came to work on his projects when the students were here

Facility Work:

  • Battery electrolyte levels
  • Fuel Transfers
  • Full general house clean
  • Tidy student house after visitors
  • Ongoing solar panel cleaning, and battery electrolyte top ups

  • Valve replacement and servicing on the salt water pump to fill the cistern
  • Filling the cistern, and then flushing the pump with fresh water
  • Some desalinator runs, successful running on just solar as well 
  • All month end reports and filing

Restoring the concrete cistern

Posted on by

Up early to fix the southern electric fence, then onto solar panels and sea water temperature and salinity measurements. Took inventory of First Aid kits, expired items. Generator ran today.

Richard T. returned to pump out and start work on the large concrete cistern, in hopes that the desalinator and restored cistern may eventually bring an end to the paucity of usable water. Two killdeer and one turnstone seen on the western part of the main  island.

 

Elephant Seal

Ecological Notes:

  • A large Male Elephant Seal came to the Island today, laid by the path in the sun for a while, and then went and settled in in the shade of the student house. I gave him plenty of room!

Soaking up some sun

 

Visitors:

  • Yesterday. the Waterfront Coordinator delivered diesel fuel and repair parts.

Facility Work:

  • In preparation for the servicing of the desalinator , the large saltwater cistern was drained. As there has never been any chemicals or grey water added to the cistern, it was drained back to the ocean. Long firehose material was used to ensure no bird nests would be affected.

DND events:

  • Many inshore detonations over the last few days.

Weather Events:

  • Sunny with a few cloudy spots throughout the day, giving way to heavy fog in the evening. Westerly winds 20 – 30 knots. Slight chop all day.

March 24 and 25

Posted on by

Wind: yesterday variable 1-11 knots, today mostly W 2-17 knots
Sea State: both days calm
Visibility: yesterday 5-15 NM, today 10-15 NM
Sky: yesterday overcast, rain then clearing in early afternoon, today partly cloudy then clear from mid morning onwards
Temperature: yesterday 5-6 °C, today 5-10 °C
Atmospheric CO2: 414.34 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

I heard back about more information on the recently arrived female juvenile elephant seal pup, with green tags E103 and E135. Dr Patrick Robinson, the Director of the Año Nuevo Reserve and Lecturer at University of California Santa Cruz, sent a report of the history of the seal’s sightings and said, “It’s always great to get these updates… we greatly appreciate it!” The seal was born in the 2018 winter season, which makes her just over two years old. She was seen a lot during the winter and spring of 2018 at Año Nuevo Reserve. Researchers took two blubber samples to study bioaccumulation. The seal wasn’t seen again until the fall of 2019, when she spent a month at Race Rocks between September 7 and October 11. Fast forward a few months, the seal came back to Race Rocks two days ago, on March 23. She appears to be in the early stages of her catastrophic moult of her fur and skin, judging by the patches on her sides.

The youngest elephant seal pup returned yesterday morning from her one day adventure in the sea. She spent the whole day sleeping by the wood pile. The oldest pup has been gone for the past two days. A new adult female elephant seal arrived yesterday. She is most likely one of the four mothers that was here in January and February. So far the three have come back a month and a half after they each weaned their pups, which happened on January 21, February 4 and February 9.

At today’s 16:31 high tide, after recording the salinity and temperature of the water, I hooked up the hoses and pump to top up the seawater in the cistern. The gas powered water pump sucks water through a hose with a strainer dropped off the end of the jetty. The water is pumped through 76 m (250′) of fire hose up to the cistern. Over a couple hours, tens of thousands of litres of water were pumped into the underground cistern, which should feed the desalinator for the next month and a bit.

Yesterday, there was one pleasure boat that zoomed through Middle Channel and stopped by the rocks to take photos of sea lions. This afternoon, the Canadian Coast Guard lifeboat Cape Calvert, appeared to be out for a cruise around Race Rocks from the base in Victoria. They came in for a closer look and a couple of the crew appeared to be snapping photos of Race Rocks with their phones. This is a very photogenic place. This afternoon, Guy, Corey and Christine from Pearson College delivered a new fridge and took away the old one that recently stopped working. They also brought some fresh food from the Pearson kitchen, which is closing down for a while.

Here are a few photos from the past two days:

March 4 and 5

Wind: yesterday 2-42 knots variable directions, today 0-31 knots from N in am and W in pm
Sea State: yesterday chop up to 1 m, today rippled then up to 1 m chop in afternoon
Visibility: yesterday 10 NM, today 5-15 NM
Sky: yesterday clear, today partly cloudy and rain in afternoon
Temperature: yesterday 5-10 °C, today 5-9 °C
Atmospheric CO2: 413.05 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The tide has been getting low in the evenings over the past two days, revealing lots of neat intertidal creatures. With no sea lions hanging out on the east side of the island, I was able to explore the rocky shoreline to see feather duster worms, sea stars, barnacles, surf grass, many types of seaweeds and long ago discarded metal pieces from former buildings and equipment at the lightstation that only reveal themselves at low tide.

There are six very stationary elephant seals on the island: one adult female, two adult males, two female pups and one male pup.

Today, I drained the cistern which stores the seawater before it gets treated by the desalinator. The cistern is a large concrete box located between the lighthouse and the main residence. It measures 12 m long by 8 m wide by 3 m deep. It holds a lot of water. The water was slightly turbid and causing the desalinator pre-filters to work harder than needed. The water pump ran for four hours to drain the many thousands of litres of water back into the ocean. I used a long pressure washing wand to reach in to clean the rocks on the bottom and concrete walls, at least the parts I could reach. Tomorrow, I will refill the cistern when the tide is higher and the intake hose can be put off the end of the jetty.

Yesterday morning, six visitors came to the island: Travis, Hilary, Antoine, Hannah, Val and Greg. There was one tour boat that passed by. Today, two tour boats were in the ecological reserve in the morning.
