There were a lot of eco tourism boats passing through the ecological reserve today. An outrigger canoeist paddled through the main channel in the mid morning and again in the early afternoon.

Tomorrow is my last day as the Ecoguardian. Mara and Kai are returning for a few months. I have enjoyed being back on this wonderful island for the past 17 days, learning on the edge where the land meets the sea meets sky. Race Rocks is a unique place that couldn’t exist without the work of Pearson students, staff, faculty, alumni and volunteers.

Here are some sights from around the island today:

The Vancouver Aquarium’s Marine Mammal Rescue Centre has been notified. Rescue Centre staff mentioned they were up in Powell River today successfully disentangling a young steller sea lion.

Here are a few photos from today:

Sea State: calm in morning, rippled in afternoon
Visibility: 10-15 NM
Sky: overcast, then clear from mid morning onwards
Temperature: 13-15 °C
Atmospheric CO2: 412.21 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Here are the numbers from today’s census:

I was excited to see the fluffy head of the sea otter this afternoon. This morning when doing the census count from the top of the tower, I scanned the kelp but couldn’t see the otter.

This afternoon, I gave TLC to the boat house, boat and boat dolly.

There was a steady stream of about two or three eco tour or pleasure boats per hour passing through the ecological reserve.

Here are some sights from around Race Rocks today:

Sea State: calm in morning, rippled in afternoon
Visibility: 15 NM
Sky: clear, partly cloudy in evening
Temperature: 11-16 °C
Atmospheric CO2: 412.58 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

There were not a lot ecological happenings to note from today. The sea lions are continuing to grow in numbers in the main haul out spots on the southwest side of the main island, southeast side near the lighthouse, jetty area, and Middle Rock. Stay tuned for the weekly census tomorrow to get the official numbers to see how the population has grown since last week.

I have been keeping track of the two steller sea lions seen recently with flashers hooked to their mouths. I only saw one this morning near the jetty. I thought I saw one which was possibly the same one on Middle Rock, although I couldn’t get a good look at it because it was facing away.

I transferred diesel to the furnace tanks in each house, in the ongoing effort to get everything stocked up for the colder months.

There were a lot of eco tourism and pleasure boats in the area, taking advantage of the nice weather.

Here are two photos from today:
