Improved Solar Power

Posted on by

Ecological Notes:

  • 5  Elephant Seals
    • The Beachmaster (Bernard) has left the island, most likely for one more big feed before molting
    • 2 Adult females, both starting their molt

    • 2 new (to me) animals here, either very large pups, or small yearlings …. waiting to see if they do a normal molt.
    • The only remaining pup that was born here has completed it’s first baby fur molt, and has been tentatively exploring the area by the pier, when encouraged by another new pup I don’t recognize

Tentative first tries

Moved into the water while he had support

 

  • 3 known Canada geese nests now, one was right by the door to the house. The gulls robbed all the eggs though, so I dismantled that nest so that they would build somewhere else.
  • Gulls and Black Oyster Catchers are pretty much all paired up now, although I have not seen any nests yet as it’s still a bit early in the season

Visitors:

  • 4 contractors stayed for 2 days to work on the solar power system
  • 3 guests of the Ecoguardian  over 2 different time slots
  • College instructors and their guests came for a brief visit and overview of the reserve

Facility Work:

  • Replacement of damaged solar panels
    • added a new array or 4 panels
    • redid most of the wiring involved

There was an immediate improvement  to the system, resulting in a reduction of generator fuel use by about 1/3. This will only improve as the days get longer and brighter.

  • Visiting guests aided the ecoguardian in some tasks better accomplished by have some else there for safety and/or lifting. (including log and firewood prep and other  wastewood and equipment moving and stacking.) they also helped with pressure washing.

Safer to cut down on the rocky shore with someone here with me

DND events:

  • 3 or 4 days of the regular blasting, with safety vessels and Marine Mammal Observers present.

Noted Vessel Traffic:

  • Ecotourism vessels are gearing up for the season and visit on a regular basis, often reporting the location of the sea otter and injured or entangled animals to the ecoguardian.
  • 2 jet skis in today … a little loud running against the current, but they kept proper speeds

 Noted Infractions:

  • Only one private fishing vessel in the reserve noted.

 Feature Event:

  • Spring is in full swing. Flowers are blooming, the pineapple weed is growing and of course the birds are all in courting behavior.

Weather Events:

  • very typical mix of spring weather …..wind from all directions on any given day, mix of sun, clouds and rain squalls.

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.

August 16 – Returning Sea Lions

Posted on by

Wind: from NE in morning, SE in afternoon, W in evening – between 2 to16 knots
Sea State: calm in morning and rippled in afternoon
Visibility: 15 NM
Sky: clear
Temperature: 16-25 °C
Atmospheric CO2: 412.54 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

While I have only provided the conditions for today, I did step onto the Rock just after noon yesterday. It’s great to be back, having spent the whole winter and the first few weeks of spring here. I will be here for the next two and a half weeks, 100 days shorter than my last stint.

I feel very fortunate to be a part of the amazing team of Pearson students, alumni, staff, volunteers, donors and researchers who keep this Ecological Reserve going.

I spent yesterday afternoon and evening reacquainting myself with this wonderful place, practicing how to avoid disturbing the young gulls, who blend in well with the rocks as they like to hide beside the paths and in plants.

This weekend, there have been a lot of boats (pleasure craft and eco tour boats) taking advantage of the nice weather. The only visitor to the island, other than me, was Greg, who drove me out here from Pearson and brought back Mara and Kai.

In the previous log post, on August 13, a branded sea lion with an attached flasher (fishing lure) was mentioned. The steller sea lion is branded O-19. Bryan Wright, the Marine Mammal Biometrician/Project Leader at the Oregon Department of Fish and Wildlife, gave us an update on the history of the stellar sea lion:

He was captured and branded by us (ODFW, along with WDFW) at Bonneville Dam on the Columbia River on February 2, 2012.  We don’t know his exact age but he was probably 5-7 years old at the time of capture, making him 12-15 now.  He then wasn’t seen again until July 21, 2016, at Tatoosh Island off the tip of the Olympic Peninsula in Washington.  He was then next seen back at Bonneville Dam from August-November, 2019.

Bryan also passed along an interesting article that was just published called “California Sea Lion (Zalophus Californianus) Monitoring In The Lower Columbia River, 1997–2018” (Brown et al 2020). Click here to read the abstract of the article.

Big Creatures and Big Winds

Posted on by

Weather: 

  • Visibility 14 miles
  • Partly cloudy, sunny
  • Wind 25-35 knots (gale warning in effect)
  • White caps and spray. Waves up to 4 m.

Visitors/Boats: 

  • The college boats are still in for maintenance, so we have not had any visitors. We are hoping to go to the main island soon but winds were much too strong and unpredictable today.
  • The past couple of days we have seen a handful of eco-tourism vessels and pleasure craft. Some vessels have approached within 20 m of our jetty and surrounding Great Race Rock. The elephant seals have been scooting up the jetty to get away and the few sea lions remaining appear disturbed.

Ecological: 

  • We were sad to find the missing gosling deceased. It seems that due to its injured foot it was easy prey for the bald eagles that have been swooping by lately.
  • We are now in the company of 4 very large male elephant seals who have stopped here to moult. They are enjoying taking regular baths in the shallow and protected jetty waters.
  • The occasional sea lion has stopped by and hauled out for a rest, but otherwise they have all moved on.
  • The seagulls are becoming more and more aggressive. We are anticipating the need to wear protective equipment sometime in the coming week!

Maintenance/Other:

  • We are still waiting for the delayed desalinator, so we are conserving water as much as we can in the meantime, as it is not possible for more to be delivered without the use of the college vessels.
  • We have been collecting shingles as the high winds are tearing them off of the sheds (new metal roofing is expected sometime soon), and often find fishing lures, bits of rope, and other litter wedged into the rocky intertidal.
  • The beautiful sunny days lately have meant that we have been able to operate entirely on solar power most days. We’ve been having some troubles with the battery charge readings but otherwise the system is working without a hitch!

Wind, Fog, and Eggs!

Posted on by

Weather: 

  • Visibility varied today. This evening visibility is excellent, 10-13 miles. This afternoon we were surrounded by fog and could not see even nearby north rock (less than 1 mile).
  • Wind this evening is blowing 30-40 knots. This morning was calmer, 12 knots.
  • Sky clear. This was interrupted mid afternoon by thick fog.
  • Water white capping and breaking into spindrift.

Boats/Visitors: 

  • Today was fairly quiet, with only a few whale watching boats in the morning which seemed to mostly keep a good distance. Greg visited this afternoon to deliver water as we are still waiting for the new desalinator. A former student visited as well.
  • The swiftsure international sailing race passed Race Rocks on Saturday, so we have been seeing the boats trickle back towards Victoria over the past couple of days.
  • Yesterday we spotted a rental boat from Pedder Bay Marina attempt to pass through the channel between our main island and the south islands.
  • Lately whale watching boats have been present viewing the elephant seals and sea lions. Many have appeared to be well within the 100m distance from sea lions required by DFO.

Ecological: 

  • Two evenings past we noticed the first seagull eggs of the season. We noticed that one nest was missing its egg the next morning. The seagulls have become quite aggressive towards us but only if we get too close to their nest by accident.
  • There are still four elephant seals on the island, two moulting, the juvenile male from this past spring, and an older female.
  • The sea lions have remained on the SE side of the island, although fewer than what we were seeing before surrounding our jetty. They have been enjoying surfing the waves periodically.
  • Another oyster catcher nest spotted on the SW side.
  • We have been finding dead seagulls presumably killed by the bald eagles that have been hanging around. They especially like to sit on top of camera three.

Other: 

  • Except for in the occasional presence of fog, we have been able to operate the island completely with solar on clear days.
  • We were in need of batteries so missed a few days of salinity/temperature data collection.

  • Wind: 5-15 NE
  • Sky: Very Sunny
  • Water: Calm

Boats/Visitors

  • Saw quite a few boats today, tour boats, fishing boats and sailboats

Ecological

  • Seems like the seals and sea lions spent most of the day either lazing in the sun or cooling off in the water, the gulls seem to be extra rowdy today, not sure why

Other

  • the batteries don’t seem to be taking in enough solar power, I find it odd that I still have to run the generator today even though its been very sunny for the past few days

More Sunshine and Wind
