July 13 and 14 – Weekly Census

Ecological Notes:

  • The sea lion population is growing. For the past few days there have been 18 Steller sea lions hauled out on Middle Rocks. That is up from four sea lions one week ago. One of the sea lions has a brand. It appears to say 620R, although the researcher I contacted in Oregon mentioned it is what they call a bad brand and he was unable to determine the brand from the photos I sent. I will keep a look out for the sea lion and see if I can get a better view. The researcher will check his records to see if he can identify the sea lion and be able to record the resighting.
  • The super moon on Wednesday night rose in the southeast at 10:00pm. It was a big bright orange orb that looked more like the rising sun, than the moon.
  • Today’s extremely low tide of -0.2m or -0.7′ was at 10:13am. The overnight high tide at 00:55am was 3.0m or 9.8′. It is apparently the lowest tide in a decade. I was fascinated to see the extended edge of the water all around the many islands. I looked at the exposed intertidal zone from a distance and up on the jetty, so as not to disturb the many delicate species.

Bigg’s Killer Whales Kill in Reserve.

The barometer rose all day and so did the westerly winds, so by the time the tide started to ebb, the opposing forces made spectacular waves. Tonight is the last full moon of the summer and it is in perigee, closest to the Earth, so it appears to be a big one, marking the third of a trilogy of super-moons we have been enjoying. It also means bigger than usual tides, making things seem even more dramatic. It was clear all day, no fog, but there are low clouds sneaking in along the Olympic Mountains and the look of fog out to sea. The westerly is supposed to be a little tamer on Tuesday.

Twenty-one tour boats were noted in the reserve today as well as one dive charter boat. A couple of the whale watchers looked like they were pushing the speed limit in the reserve and pushing the marine mammal viewing regulations outside the reserve. No illegal fishing was observed.

I am adding photos to the sea lion branding/tagging observations and that will make the data much more rigorous. Another entangled, aka ring-necked California Sea Lion was photographed. This time it looked like plastic strapping cutting a deep and infected wound.

Bigg’s Killer Whales visited again today. It appeared that they chased Steller Sea Lions all the way here from at least Albert Head. It was very dramatic here as they wove in and out of the kelp and through the tidal rips and standing waves, going with the tide and at great speed. One exhausted male Steller’s hauled out just as the chase was passing and he looked as though he may have been part of it all. He collapsed in a heap and immediately went to sleep. He was the lucky one. The kill happened in the reserve, just southwest of Great Race. There appeared to be a fairly small baby in the family of whales. The group was purportedly the T-61s (not sure of the source however). I tried to take photos so will report back with verified identification information once that comes in.

I finished some more of the set up to protect the ‘Science House’ today and started to clean out the northwest entrance to the generator room. There is a lot of very satisfying cleaning here, when you sweep you really get results, today it was many, many, generations of Ligia pallasii exoskeletons. Wow it’s a moult room instead of a cloak room.
