We Have a Weaner

Posted on by

Wind: yesterday and today 5-25 knots between E and N
Sea State: yesterday and today rippled with afternoon NE swells of up to 1 m
Visibility: yesterday 10-15 NM, today 3-10 NM
Sky: both days mostly cloudy with periods of rain
Temperature: both days 7-10 °C
Atmospheric CO2: 414.07 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

On Tuesday night, the first elephant seal mother left the island, leaving her 24 day old pup to fend for itself. The mother had the tail flipper tag T562. The pup is still hanging out with the harem on the lawn.

The island is running on reduced power due to an issue with the generator, which is in the process of being fixed.

Four eco tour boats were in the reserve over the past two days. There were no human visitors on the island.

See the photos below for a few sights from the past two days:

This morning, I heard a ruckus outside the west side of the house, where the a few of the elephant seals have been hanging out. The largest male appeared to be fighting the small juvenile male, while the female watched. The adult was slamming its head down onto the juvenile and biting it. This lasted for a few minutes before the juvenile and female fled to the north side of the path.

While I was doing the census in the middle of the day, there were three people snorkelling off the southwest of Great Race Rock Island. They took turns snorkelling in pairs, while one person stayed in the boat. Six other pleasure craft and eco tour boats were seen in the reserve over the past two days.
