Our Last Day on Station!

Posted on by

I cant believe it has been a month already!

We spent our last day doing the end of month and, end of shift tasks, like taking stock of fuel used, and uploading the water sampling data set.

We also made sure that everything is ready for Kendra, the next Eco-Guardian.

Sharing a space with 1000 + Sea Lions and Seagulls has been an interesting time, and I think it will take me sometime to get used to the silence.

Until next time – Neha and Scott

Weather: Sunny all day, Winds pretty steady around 8knts SE All day

Our Last Census Day!

Posted on by

Sunday, September 29, 2024

Today was our last census!!!

We took our coffees up to the tower for the 7am Low tide.

Animal Census:

Birds:

  • Gulls: 1580
  • Cormorants: 22
  • Canada Goose: 22
  • Turnstones:
  • Shorebird: 1

Would love help on the ID of this.. email us if you know!

Mammals:

  • Stellar Sea Lion: 306
  • California Sea Lion: 834
  • Harbour Seal: 81
  • Elephant Seal female: 2

Animal Tracking and Injuries:

Spotted a Stellar Sea lion with fishing line wrapped around his neck ☹

Reported to DFO.

Since we are leaving on Tuesday, we spent the day cleaning the house, and washing the windows.

As well as our daily fence repair. It’s a particularly nauseating feeling to wake up each morning, look out at the beautiful view, and survey the extent of fence damage that has happened overnight…. This is a task I definitely will not miss.

Weather: Sunny all day, Very windy all night (35+ Knts, dropping all day to around 20knts W/SW)

Water Woes

Posted on by

Friday, September 27, 2024

Unfortunately for us, the levels of water in the massive cistern beside the house are low, so we have not been running the desalinator lately, and despite our best water saving efforts we need more …

Until the sea lions (and the massive amounts of poop that comes with them) clear out we aren’t able to fill the cistern with seawater. So…  today, Greg came out with a massive tank of freshwater on the back of the Second Nature to top up our reservoir.

This was a bit of a production as we had to lay out ~ 75m of fire hose from the reservoir to the dock, but we did it, and now we won’t be leaving the next eco-guardian in a lurch.

On another note, we have a returning Elephant Seal. This lady is untagged, and definitely knows her way around the island. We first saw her at 11 am on the jetty, and by 2 pm she was in the grass by the main path to the house.

I hope she sticks around for the weekend!

Weather: Sunny all day, Wind at around 16knts SW all day.

Grey Days Ahead!

Thursday, September 26, 2024

Finally, some real lighthouse keeping weather! Greg paid us a visit with a freshly tuned up Second Nature. We topped up the large diesel holding tank that is used to power the generator. We laid out some firehose as tomorrow we will top up the fresh water holding tank. Normally, we are able to make our own water but the cistern is running low and the area where sea water is pumped from is right where the sealions are hanging out.

Weather: Intermittent rain all day with brief periods of heavier fall. Wind 8-14kt with some heavier gusts.

Elephant Seal Frustrations

Posted on by

Tuesday September 24, 2024

This morning we woke up to fog lapping at the shores of the island. Its honestly very magical to be fully socked in on a rock that you know is completely surrounded by water. But also, this really throws the problem of a malfunctioning foghorn into sharp relief.

We were obviously not alone in this thought, as we read an 8am email from the Coast Guard team who will be out here tomorrow to take another stab at repairing it.

We spent the morning cleaning the solar panels, making the daily fence repairs, and doing some general tidying for the week.

We also tried to capture some more identification photos of the Elephant Seal who has been around. Last week we reported her with my best guess of her tag number based off a couple glimpses from when her tail was at just the right angle.

The group we reported her to responded right away with a bunch of interesting information about her life. She was born in Ano Nuevo California in 2013. She has been spotted there many, many times since then, during the winter months, and has even had two babies of her own!

But they have no sightings of her in other locations up until now! So that is super exciting!

From a Race Rocks perspective, she also seems to be a Newcomer. Elephant seals have full reign of the island, and the guys who visit here often know that, and take advantage of it….. as recorded in many previous blogs,

This gal, however, is hanging down on the rocks on the South side of the island amongst all of her Sea Lion relatives.

In addition, speaking with some of the previous Eco-Guardians, there is usually another seal (Beverly) who is the first to arrive. She has a pink tag.. so we know this is not her. Maybe there is new newcomer on the block….?

The previous eco-guardians also shared this neat image, that shows the tag color correspondence with animal birthplace!

What a cool and simple way to track such amazing animals!

Anyways, I will continue on trying to get a clear tag picture.

Census on a Cloudy Day

Census Day!

This morning, Scott and I headed up to the top of the tower for our weekly animal count.

We added the elephant seal to this week’s survey because she is still sticking around!

Yesterday we beefed up the fence on the West side of the island between the helipad and the generator shed. Since this one isn’t anchored into the bedrock, it has been taking quite a beating from the westerly winds.

Greg also dropped by yesterday and gave us some groceries for the week. The water cistern is quite low, so we have ceased using the desalinator, and are trying to be more conservative than normal with the water. Fingers crossed, Greg will be able to boat over some more water this week!

Today, we checked and topped up the batteries, and tidied up the basement in the main house. I can’t believe we only have a week left on the island!

Elephant Seal!

Posted on by

Friday September 20th

Last night while we were fixing the fence on the South Side of the Island that had been knocked over….Again.. we spotted a seal looking a little different than everyone else

Looking a little closer, we realized it was an elephant seal! Looks like a small female, and she is tagged, though we couldn’t get a good photo of it. We reported it to the biologists from California who implement that specific tagging study.

Also saw a couple more branded Sea Lions who we also reported, as well as a dead sea lion we spotted along the south side of the island at low tide.

Scott has worked his way through the pile of wood piled down near the Jetty, so the next Eco-Guardians will def be warm for a while.

The Journey of #444X

Posted on by

Wednesday September 18, 2024

Not a huge day facilities wise. We did our daily repair of the electric fences, and chopped a little more wood.

However, we did receive some cool news from Brian Wright, the NOAA scientist who we reported the branded sea lions to. He told us that number 444X, was first tagged in Astoria all the way back in 2016, and he has not been reported since.

This information is super valuable to scientists and managers because it shows what areas are being used by these animals, the extent of their ranges, and how long they can live. (Which for a California Sea Lion is 15 – 25 years!).

Mark and recapture studies are also very important for estimating functional population size, and this type of study design is used for lots of fundamental ecological work. This infographic from FishBio, nicely explains how a mark-recapture study can work in an open environment! Again, this is a good reminder to report any tagged animals you encounter!

Tagged Sea Lions

Posted on by

Scott spent some more time with the chainsaw today. He is putting a huge dent in the pile of logs down by the jetty, and the stacks of firewood in the basement are steadily growing for the winter.

As the numbers of sea lions on the island continues to climb we have been seeing quite a few tagged and branded individuals. These markings are implemented by researchers in Oregon and along the West coast of the US. They give the researchers an idea of animal movement, functional population size, and more. If you ever see a tagged or branded sea lion remember to report it!
