Moulting is Itchy Business

Weather and Sea Conditions

After a hesitant start, with locally overcast skies and fog to the southeast, the sun was blazing by afternoon and it stayed that way into the evening. The UV index rose to almost 6 today, which is high. The wind started at 15 to 20 knots from the west, dropped and turned to the south and southeast and then returned to west15 to 20 knots by early evening. The barometric pressure stayed fairly steady between 1005 and 1010 hPa. The forecast calls for the westerly to increase to 15 to 20 early this evening and to 20 to 30 late this evening, then to drop to 5 to 15 knots late overnight. They expect a similar wind pattern tomorrow with more cloud.

Vessel Observations

Seven whale watching vessels were documented working in the protected area today and most followed the rules. One yellow zodiac exited past West Rock heading west, at high speed. Better communication is needed about boundaries, limits and a reminder about keeping at least 100 meters away from marine mammals might be helpful. I know these ecotourism operators want this good thing to last.

Ecological and General Observations

A nice low tide this morning exposed all the beautiful new seaweeds of the season. Bull kelp is growing fast and the Mazzaella splendens is a rich, iridescent burgundy colour. Fresh kelps like Alaria, Laminaria and Cymathere triplicata festoon the rocks in the lower intertidal areas. Up high, the more ephemeral species of nori and sea lettuce are starting to go reproductive and lose their ‘bloom’.

A high density of grazers, keeps the seaweeds in check and feeds the gulls and oystercatchers.

More elephant seals arrived today bringing the number moulting in the garden to eight. On land they are the epitome of lethargic. It is a real treat to watch them in the water, they are so graceful and languid as they chase and roll and spin in slow motion. I also see the River Otter and Sea Otter daily, which is always interesting. The Sea Otter hung out with the Harbour Seals today while they were hauled out on South Rocks. He just floated a couple of metres away as they slept on the rock. He dozed in the water, using the back eddies to stay close. Later he positioned himself in a back eddy that kept him almost stationary, while meters away the current that blasted past at almost six knots. Very savvy sea otter.

There were a lot of shorebirds today, about fifty Surfbirds, a few Rock Sandpipers and a couple of Dunlin. The Black Turnstone numbers are swelling too so I think the migration is happening. The turnstones I watched foraging seemed voracious.
