Cleaning and Maintenance

Posted on by

Ecological Notes:

  • 7 Elephant Seals, including 2 “pups” still using the grass areas
  • Monday saw a dramatic reduction of animals and birds in the reserve (almost no guillemots or Sealions, and about half the number of gulls) but they are gradually returning.
  • An anecdotal possibility is that Sunday night had a 50+ knot storm, lining up with a high tide and lots of big ocean swells, making the reserve a very nasty place to be!
  • Noticing more Black Oyster Catcher nests. These are more just an indentation in the gravel, and the birds rely a lot on the camouflage of the eggs. Due to high egg loss rates (here, primarily gulls snatching them), Oyster catchers can lay up to 3 or 4 replacement clutches in a season.

Very distant photo

Visitors:

  • Guests left Sunday
  • 4 Pearson College students on Monday, for an informal visit, with some discussions on marine mammal adaptations life in the ocean.
  • Was also nice to re-instate the visitor log in the newly painted and repaired Visitor Welcome Box

Facility Work:

  • Trouble shooting power interruptions originating from the Student Building
  • Cleaning and minor repair to the housing on the Camera 5 unit.
  • There’s an old prairie saying “Make hay while the sun shines” …… out here, the addendum could be “Clean stuff while the rain falls!” Rain makes it much easier to clean paths and windows, and through the rain collection, provides water for the pressure cleaner.

DND events:

  • 6 or 7 loud blasts today, all sealions left the rocks again

 

Weather Events:

  • Westerly winds, 15-20 knots brought rain showers in the morning. Mostly sunny with cloudy periods in the afternoon. Calm seas. Clear skies and 20 knot westerly winds in the evening

Oyster Catcher nest

Posted on by

Ecological Notes:

  • 7 Elephant seal on the grass, including 2 pups. 4 have moved the furthest away from the ramp as I have seen them (towards the southern side of the island, but still up in the grass)

By the solar building

  • Knowing the extra importance of staying off the rocky/gravel areas this time of year, I did my normal perimeter check from the grass, and solid rock areas. I noticed a Black Oyster Catcher doing more of a distraction behavior rather then their normal “go away” squeals.
  • I immediately left the area and searched from a distance with the spotting scope. It took a while, but sure enough I found the nest!!!! (my first ever sighting)
  • Although always true, I CAN’T STRESS THIS ENOUGH – photos shot from as far away as possible, with a 600mm equivalent, then cropped to show better detail! (please read the captions)

Facility Work:

  • More waste wood stacking ……. Due to the obvious fire ban in the reserve, and to the unknown paint content, all waste wood has to be removed from the island and processed properly. Making it easier and safer for the recovery team just makes sense.

DND events:

  • 6 detonations during the day

Noted Vessel Traffic:

  • none (DND vessels kept area clear)

Weather Events:

  • Westerly winds during the day at 10 – 15 knots, increasing to 25 knots early evening.
  • Fog in the morning, followed by mainly clear skies, then fog returning in the evening. Low fog throughout the day to the west and south.

All day distant fog

Evening fog, can’t see the mid channel rocks

Antenna Re-mount

Posted on by

Ecological Notes:

  • 5 female Elephant Seals, 1 juvenile male (about female size)
  • Elephant Seal pups: 2, 1 is a young male
  • Many big old California Sealions tried to take over the pier today
  • Can see several paired up Black Oyster Catchers, but no “nests” visible from the angles I could view from a distance. Also didn’t note any defensive behavior.

Facility Work:

  • Moving beach wood, cut some to stock up firewood
  • Remounted VHF antenna, ONLY because the deck builders ran out of time. First I tried the hard ways, then just dismantled it on the bench and cut the wood away from the mount.

 

Noted Vessel Traffic:

  • 1 Sailboat, doing it the right way! Motor on, sail in centered position and loose, straight down the center of the channel slowly, without disturbing the wildlife.

 

Feature Event:

  • Learning to use the chainsaw, but having to pause when an elephant seal wanted to pass.

 

Weather Events:

  • Medium Winds from the west, rising in the evening. Clear skies all day, good for Solar Power generation. Light cloud moving in the evening after sunset.

There were a lot of eco tourism boats passing through the ecological reserve today. An outrigger canoeist paddled through the main channel in the mid morning and again in the early afternoon.

Tomorrow is my last day as the Ecoguardian. Mara and Kai are returning for a few months. I have enjoyed being back on this wonderful island for the past 17 days, learning on the edge where the land meets the sea meets sky. Race Rocks is a unique place that couldn’t exist without the work of Pearson students, staff, faculty, alumni and volunteers.

Here are some sights from around the island today:

Sea State: calm in morning, rippled in afternoon
Visibility: 10-15 NM
Sky: overcast, then clear from mid morning onwards
Temperature: 13-15 °C

I was excited to see the fluffy head of the sea otter this afternoon. This morning when doing the census count from the top of the tower, I scanned the kelp but couldn’t see the otter.

This afternoon, I gave TLC to the boat house, boat and boat dolly.

There was a steady stream of about two or three eco tour or pleasure boats per hour passing through the ecological reserve.

Here are some sights from around Race Rocks today:

August 20 – Two Pods of Transient Orcas!

Posted on by

Wind: W at the beginning and end of day, NE mid morning to early afternoon, 4-18 knots
Sea State: calm
Visibility: 0-10 NM
Sky: fog in morning, clear in the middle of the day, overcast in afternoon, rain in evening
Temperature: 12-17 °C
Atmospheric CO2: 412.15 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

There was a lot marine mammal activity today. At 11:00, two pods of Bigg’s transient killer whales were in the ecological reserve. One pod appeared to have about six whales. The other pod appeared to have three. Both pods spent a lot of time around the South Islands. A nearby whale watching boat captain mentioned on the VHF radio that the orcas were two families most likely having some social time. They were probably having a good meal too. I didn’t see any hunting happening on the surface. Transients eat marine mammals like seals. I did see a lot of harbour seals not taking any chances, huddled together on nearby rocks and around the east bay beach, looking towards the areas where the orcas were swimming. The transients stayed around until at least 3:30.

See the photos below for views of the orcas and other sights from today:
