High tides and winds

Posted on by

Ecological Notes:

  • As noted previously, there was a drop in all animals and birds during/after the storm surge, but they are starting to return
  • No elephant seals have returned yet …. checking past blogs, this is not uncommon, but was still hoping there would be some here before I leave!

Facility Work:

  • In addition to weekly battery electrolyte top ups, cleaned the tops of the batteries and did an extra mop up of the floor
  • Due to heavy winds and rain from the north, and the old door still in place, the battery room flooded and needed a full mop out
  • After an initial clean out, debris is starting to fill the boat ramp area again. Many logs rolled right over the jetty!
  • Did a full strip down of the jetty electric fence for now

  • Sticking as close to the proper times as possible, daily salinity and temperature readings adjusted to get safely out onto the jetty

DND events:

  • One blast Monday morning

Noted Vessel Traffic:

  • High winds kept boats out of the area

 

 Feature Event:

  •  As there are ongoing concerns about the battery readings, I’ve gone to a hybrid running pattern……. leaving the system on “Auto” to avoid shutoffs from sudden low voltage readings, but shutting off and switching to “Manual” when the batteries reach 100% to avoid extending float charges (sometimes as long as 4-5 hours extra.)
  • Consulting with  technicians on further adjustments and battery corrections

Weather Events:

  • Monday, December 16:
    • Sky:Bright overcast with small clear spots
    • Wind: N 20-25kts, dropping in the afternoon
    • Sea: rippled, wind against tide chop north of reserve
    • Temperature Low 4oC, High 8oC
  • Tuesday, December 17:
    • Sky: Foggy until mid-afternoon, clear and sunny to overcast, mix of cloud and sun by afternoon
    • Wind:NE 5kts veering E to 35kts mid day, back to NE 10kts  by evening
    • Sea:  3 ft swells mid day, large swells rolling into the jetty area
    • Temperature Low 4oC, High 9oC
  • Wednesday, December 18:
    • Sky:Clear overhead, some low cloud and mist in the distance,
    • Wind: W gusts to 50kts early morning,dropping over the day to 10kts
    • Sea:  2 ft chop, dropping to smooth by late afternoon
    • Temperature Low 8oC, High 12oC

After the surge

Posted on by

Ecological Notes:

  •  the sea lions have taken the jetty over…… most posts damaged by them and the weather. It will require a rebuild after this storm front
  • Storm surge, combined with high tides have resulted in the jetty being totally awash with both water and logs
  • Sea Lions have scattered around the rest of the island, moving around based on wind and swell direction
  • Many birds left the reserve during the surge and took a day or 2 to return
  • Sill a couple Humpbacks viewable from the reserve

Facility Work:

  • as usual, repair fencing after last storm surge
  • Fuel transfers

Noted Vessel Traffic:

  • Only a couple Eco-tourism vessels noted

 Feature Event:

  •  Good news/bad news …. the storm surge and high tides removed all the debris from the ramp and jetty area, but also removed the good firewood logs that were there as well!

    • Sky: Overcast with light rain showers
    • Wind: S SE 10-15kts rising to ESE in the evening
    • Sea: Swell to 3 ft
    • Temperature Low 4oC, High 8oC
  • Saturday, December 14:
    • Sky: Overcast with low lying haze to the south,  light rain in the morning, becoming heavy squalls by afternoon
    • Wind: Gusting ESE to 35kts early in the morning, dropping to S 5kts by noon
    • Sea:  2 ft swells creating surge and wash from the NE
    • Temperature Low 3oC, High 8oC
  • Sunday, December 15:

unplanned break

Posted on by

I took ill last week, and left the reserve for 4 days. The generator system was set to auto, and the island was visited once to do a fuel drop off and top up the generator tank.

 

Ecological Notes:

  • Although i reported little disturbance during the DND blasting, the last day was larger blasts on the southern most point, the by the next day, virtually all the Steller Seas Lions that have been hauling out on the north side of the main rock (next to the pier) have moved to the southern side of the main rock
  • Lots of juvenile and adult Bald Eagles visit each morning, actively chasing birds, while still scanning the sea for fish

Facility Work:

  • While eco-guardian was away, the generator was run on Auto. It manages the batteries differently that way, and we will analyze the results.
  • Fuel delivery to the island, transfer and topping up of the gen tank

DND events:

  • some blasting early in the cycle

Noted Vessel Traffic:

  • Ecotourism and private vessels

Weather Events:

  • Friday, December 06:
    • Sky: Overcast with light showers in the evening
    • Wind: N 10-15 kts, veering to NE by afternoon
    • Sea: rippled to 2′ chop
    • Temperature Low 3oC, High 8oC
  • Saturday, December 07:
    • Sky: Overcast with heavy rain squalls in the morning, giving way so clear periods in the afternoon
    • Wind: low S early morning, veering to W 25-30 kts during the day
    • Sea:  chop turning to light waves by afternoon
    • Temperature Low 3oC, High 7oC
  • Sunday, December 08:
    • Sky: Foggy until mid-afternoon, clear and sunny to overcast
    • Wind: W/WSW 16-37 kts
    • Sea:  light chop turning to high waves by evening
    • Temperature Low 4oC, High 9oC

Clear skies

Posted on by

Ecological Notes:

  • The Elephant Seals, the expecting female and the young female, left the ramp area and haven’t returned …. hoping they’re just off having a good feed and not looking at another haul out spot.
  • In the past, most of the Steller Sea Lions have moved to the outer rocks, leaving the main rock to the California Sea Lions… but this season there are many more Stellers remaining on the main rock, even some have ventured onto the pier

Visitors:

  • Parcel and supply delivery by the waterfront team

Facility Work:

  • got some of the deck algae sprayed down during the nicer weather…. until the sprayers broke!

  • Finally got some good logs in, shortened at the holding area, and moved up to the bucking area
  • Weekly Battery maintenance
  • Monthly Equalization charge to the Batteries
  • Month end reports and posting
  • The waterfront team brought out, and prepped a new door for the battery room, appears to now also need a new door frame

DND events:

  • regular blasting, a few times a day for the last week, no noted reaction from the wildlife.

Noted Vessel Traffic:

  • In addition to a few eco-tourism vessels, there have been a few private vessels visiting the reserve, all with good behaviour

 

Weather Events:

The last week has been primarily N NE winds, leading to mostly clear skies and dry weather. Seas have had light chop, slight fog daily on the shoreline away from the reserve.

  • Thursday, December 05:
    • Sky: High overcast, fog on the southern strait
    • Wind: NE winds 10-15 kts
    • Sea:  light chop
    • Temperature Low 4oC, High 8oC

Holiday “break”

Posted on by

Ecological Notes:

  • Although the winds and storms haven’t been as high as in the past, most of the smaller birds seem to have left the island
  • As is common, the Steller Sea lions tend to always move to the most lee side of the island in the bad weather

Facility Work:

  • Bucked all available logs, ready for splitting

  • Tried to salvage some really good logs, but lost them in the swells before the tide dropped low enough to anchor them

  • Due to the past issues with batteries, mopped down the battery room twice …. once with a baking soda solution, then again with soap and water

  • Replaced batteries in the student building smoke detectors

Noted Vessel Traffic:

  • Still the occasional Eco-tourism vessel

Weather Events:

  • Sunday, December 22:
    • Sky: Brief period of fog in the morning, then clear
    • Wind: Variable calm, rising to E 25 kts
    • Sea: rippled to 2′ chop
    • Temperature Low 6oC, High 9oC
  • Monday, December 23:

    • Sky: Overcast
    • Wind: NNE 5kts in the morning, rising to 40kts gradually over the day
    • Sea:  Waves and swells to 6 feet
    • Temperature Low 7oC, High 9oC
  • Tuesday, December 24:
    • Sky: Clear overhead in the morning, low cloud and mist in the distance… medium overcast by afternoon with sunny patches
    • Wind: W 25kts in the morning, evenly dropping through the day to 15-20kts
    • Sea:  2-3 foot chop, smoothed over by afternoon
    • Temperature Low 7oC, High 10oC
