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.

This morning at sunrise, the elephant seals saw their shadows. As the lore goes for their fellow mammal the groundhog, that means six more weeks of winter. Hard to believe with the crocuses blooming and daffodils buds almost ready to burst. Although, there is snow in the forecast for tonight and tomorrow as the temperature drops to 0 °C.

There were no visitors to the island. Two eco tour boats were seen in the reserve this afternoon.
