Vessel – Abigail fishing in Race Rocks RCA

First observed at location *F with binoculars at 0857, they saw me on the deck and reeled in lines. I returned to deck and took photo 1 as they jetted away. (high speed within the reserve)

They returned to the RCA at 0922, photos 2,3,4 taken for overview of location and ID.

After photo 5 and 6, I attempted to contact them on VHF 16 and 68 (was just going to politely suggest they check the regulations for Rockfish Conservation information). They were even closer to the North Rock by this time.

They looked up, reeled in lines fast, and again jetted off.

Reported to DFO Fisheries Violations Hotline – 1-800-465-4336

Emailed in this report to DFO, as requested during phone conversation

New and Old

Posted on by

Ecological Notes:

  • 1 Juvenile Male and 1 female Elephant Seal still on the island
  • Fewer Sealions over the last couple stormy days

Visitors:

  • Yesterday, the waterfront coordinator brought over some packages, drinking water, and a tank of water for the large tank. Hopefully this will be the last large tank, as we’re finishing the maintenance on the desalinator and cistern this month!

Facility Work:

  • Learned how to sharpen and service the chainsaw blade properly today (thank you YouTube). Probably not perfect, but it cuts way better now.

New files really helped

  • Although done on a regular basis it was a nice day to clean the solar panels, albeit windy. This picture shows a nice juxtaposition of the new and the old, realizing that the builders of the lighthouse never envisioned what the future would hold …… yet the installation of the panels wouldn’t be needed in the absence of the lighthouse and facilities.

Daylight, converted to power, for the Night Light

Noted Vessel Traffic:

  • 4 Private vessels

Weather Events:

  • Last night’s wind and rain storm, with gusts up to 45 knots gave way to more westerly winds, rising from 15 knots in the morning to 35 knots by late afternoon. Wind with tide most of the day led to 2 meter swells. Cloudy with sunny patches throughout the day.

Gull Activity

Posted on by

Ecological Notes:

  • Only 2 Elephant Seals left. The largest of the Females, and the Juvenile Male, who is slightly large than the female. Glad(?) to see the last male pup move to the ocean, as he was getting very thin, and looked to be loosing energy. Hopefully He’s off to regain weight and start growing again!

Not too hungry yet, we like it here!

  • The Gulls have nests everywhere, and for the most part are pretty mellow, until an eagle or tern flies over. Every now and then they fly up behind me, but drop quietly if I turn and face them.

Gull Display

Visitors:

  • Shorefront coordinator delivered groceries and supplies yesterday.

Facility Work:

  • Oil and filter changes on the Generator. Service of batteries.

Generator, used only for short periods when there hasn’t been enough Solar power to keep the batteries up.

 

Noted Vessel Traffic:

  • 3 private vessels, short sightseeing visits.

Weather Events:

  • Westerly winds all day, 20 – 30 knots, rising to 35 – 30 knots late afternoon. Light fog in the morning, sunny and clear all day. Heavy haze in the evening, not quite dense enough to be called fog. Swells up to 2 meters, with 1 meter chop on top of that.

Caspian Terns

Posted on by

Ecological Notes:

  • 4 Elephant Seals still in the grass area, including 2 adult females, 1 juvenile male, and the last male pup from this season.
  • 6 Caspian Terns did a few flyovers today making their distinct screeches, upsetting the gulls to no end! Try as I might, I could not get a good photo though.
  • The oldest of the Canada Goose goslings are very large now, larger than the gulls, so they just meander through without worrying

Facility Work:

  • Stripped down and cleaned chainsaw.
  • Sweeping and cleaning out buildings to prepare for good scrub down when water supply permits.

DND events:

  • At least 6 extra loud blasts today. Noted Sea Lion disturbance, most moved off the rocks by the pier and to the outside rocks to the south. Most Steller Sea Lions headed to the water and haven’t hauled out again yet today.

Noted Vessel Traffic:

  • 3 private vessels, sightseeing
  • 1 dingy size sailboat with an outboard, entered the channel and tried to exit against the current, a couple close calls when the current caught them, but they eventually turned and exited with the current.

Weather Events:

  • Shifting winds most of the day, variable from west to north to east then back to westerly in the evening. 5 knots, rising to 15 knots late afternoon. Warm, clear skies and calm seas with a really nice sunset.

Nest Building

Posted on by

Ecological Notes:

  • 4 Elephant Seals still in the grass area, including 2 adult females, 1 juvenile male, and the last male pup from this season.
  • This one was napping at the junction of 4 pathways. Normally not a big deal, but right now there are gull nests everywhere!

You can leave the cart and wheelbarrow alone for now.

  • While there are too many Gull nests to count, other pairs are still courting and nest building.

Noted Vessel Traffic:

  • 6 Ecotourism Vessels
  • 4 Private vessels sight seeing

 Noted Infractions:

  • As usual, private vessels coming up to speed while still well within the reserve.

Weather Events:

  • Westerly winds 10-15 knots most of the day, with a shift to southerly winds for 2 hours mid day. Overcast and warm, basically calm seas.

Enjoying the sun

Posted on by

Ecological Notes:

  • 4 Elephant Seals still in the grassy area
  • I’ve been watching an interesting behavior of one of the female Elephant Seals but can only speculate on the reason…. She has spent 3 days in the very thick Pineapple Weed. This plant produces as very sweet smell when crushed. Every time she wakes up, she moves forward, then thrashes about and slams her head into the fresh patch. She breaths deeply for a while, and falls back asleep!

Crushed trails

nestled in for a sleep

Facility Work:

  • After confirming the need last week, and insuring the system was working properly, it was time to do some minor repairs and modifications to the pier electric fence. Sunlight, salt water, waves and animals can be hard on electricals!

Weather Events:

  • Westerly winds of 20-30 knots all day. Large swell and chop until midday when the tide turned to a flood, which smoothed thing out a lot. Sunny with  light haze at water level, but still pretty good visibility.

  • Even though the goslings are different sizes, the 3 “families” of Canada Geese were grouped up today, perhaps for better protection.

  • Shut down the composting toilet system in the student building for the season.

Noted Vessel Traffic:
