Wind: every direction throughout the day 0-24 knots
Sea State: calm in morning, rippled in afternoon
Visibility: 0-10 NM
Sky: fog and patches of rain in morning to mid afternoon, partly cloudy in afternoon to evening
Temperature: 12-18 °C
Atmospheric CO2: 412.15 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The juvenile female elephant seal tagged V173 slid her way up the boat ramp this morning. She is looking healthy and well fed. She has visited several times over the past few weeks, as well as in the spring to moult and briefly in December. She was born last year on Drakes Beach, in Point Reyes National Seashore, in California. Researchers tagged her as a weaned pup on February 28, 2019.

I did some maintenance around the island: changed the oil in the backup generator, tidied paths with the trimmer to make it easier to move fuel and equipment with carts, cleaned the solar panels, washed windows on the main house, and pressure washed the stairs leading up to the door of the lighthouse to get rid of the slippery bird poop. Greg brought 800 litres of fresh water, which we pumped up from the jetty to the fresh water tank.

Here are two photos from today:

August 16 – Returning Sea Lions

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.

A New Arrival

Posted on by

Today’s Weather Conditions: 

  • Sky overcast
  • Visibility 15+ NM
  • Wind 15-20 knots W
  • Sea state: calm, fast moving currents today (almost 5 knots)
  • Daily fog in the mornings and often late afternoon as well

Marine Traffic/Island Visitors:

  • No island visitors aside from Greg on Thursday with supplies
  • Quite a few whale watching boats today and yesterday (20+)
  • Not many pleasure crafts passing through the reserve, but many outside of pedder bay (especially yesterday)
  • We saw 3 whale watching boats just outside the reserve circle a small group of orcas and follow them under power into the strong currents earlier this afternoon.

Ecological Observations: 

  • Today we were joined again by elephant seal V173. She was also here in December and again in the late spring when we first arrived. Her left eye is a bit oozy and red, but it seems like it is still functioning properly and she is otherwise looking great! She must have eaten a lot of fish out there- she’s much bigger than the last time we saw her only a few months ago.
  • The seagull chicks have been wandering farther away from the safety of their nesting areas, and we have been seeing quite a few more deceased chicks on the ground all around the island. They are being killed by rival gulls protecting their territory and young. There are a few chicks with injuries from these attacks, such as broken legs or wings.
  • We found an eviscerated gull chick on our back step on Friday afternoon. It looks quite a bit like a chicken does when a mink kills them (head missing), so we wonder if this is the work of a river otter.
  • As mentioned above we observed a few orcas just outside of the reserve earlier today. We have also been seeing humpbacks passing quite far away in the straight.
  • The pigeon guillemot nest that we have been observing closely (near our back porch) has at least one chick! We carefully peeked into the crevice and caught a glimpse of a tiny puff of black downy feathers. We are excited to be able to watch their activity so closely from our window as they are very secretive with their movements typically.
  • The remaining male elephant seal has been venturing to other parts of the island as his moult is finishing up. He has been finding some creative places to wiggle over rocks into shallow pools heated by water spilling over sun warmed rocks as the tides rise.
  • We heard a surfbird’s call today while out near the jetty- it’s a very shrill sound, just like the second recording here.

  • There are now 5 elephant seals, two of them tagged, the small pink tag is still around along with a familiar one green tag C887 who I called Flounder last year.
  • Two bigger males, one of them the familiar Bernard, a slightly smaller guy and then flounder being the smallest male along with two females that are under a year old.

  • Seems like some of the sea lions came back when the storm hit, it was blowing up to 40 knots on Wednesday but today it has finally come down to almost nothing
  • A couple different birds also came by, I’ve been seeing a lot of ravens lately, eagles, snow buntings and one whimbrel
  • There is a little elephant seal by the jetty today, pink tag V173
  • Thankfully the storm brought in some driftwood than can be cut up and dried out for next winter
