Shift Changeover

Posted on by

Wind: 0-20 knots NE
Sea State: 0.5 m chop
Visibility: 15+ NM
Sky: overcast clearing to sun in the late morning
Temperature: 8 C
Atmospheric CO2: 412.73 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday, Laas’ shift ended after being on Race Rocks for the past two and half months and a big chunk of the past two and a half years. I came out to the island at noon on Second Nature with Guy, Corey, two students, a family visiting the college and a friend of Laas. It was great to share in the excitement of all on the boat. I also appreciated their help carrying my many bins of food. I always get excited when the boat rounds the corner out of Pedder Bay and the lighthouse comes into view. The cacuphony of seal lion barks and belches was overwhelming when the boat pulled up to the jetty. Thanks for the great welcome home, my pinniped pals. I had a run through of the energy systems with Laas, Guy and Corey, as the equipment has changed completely since I was here almost five years ago. It’s great to be back on the Rock. Thank you Laas for leaving the place so tidy. Best of luck on your new adventures.

After the group left, I climbed the 99 steps inside the lighthouse to get a bird’s-eye view of the island. I spend the rest of the day reacquainting myself with the place and unpacking. I welcomed the slow down, as I settled into the island that I will call home for the season, watching the changes as the days become longer. I will be here for all of winter and depart soon after the vernal equinox.

Today, I continued to check out more places and do the regular tasks like monitor the energy levels, wash the solar panels, turn the composting toilet and sample the salinity and temperature of the water at high tide. On one trip up the lighthouse, I counted 336 sea lions on the rocks. There are also six elephant seals on the main island: three large males spaced apart from each other, one pregnant looking female in the centre of the island and two juvenile males.
