Census and gale again in the evening

Weather

At 8:00:10 North East wind ,calm and overcast .Rain in the morning and no wind at all around 10AM .The usual calm weather before a storm and  around 6:00PM to 11:00, The wind from West raised steadily from 20 to 40 knots . We noticed that the darkness is coming only after 6H30

Vessel and aeroplans

The morning was really calm so it was easy for me to notice that something was wrong…like a chainsaw running somewhere and looking by the window all around the rock you could see a small grey zodiac, full speed creating a panic all around!!! Finally It headed to Pedder Bay…End of the story. I Coast guard’s helicopter

A Stormy Census

Ecological Happenings

  • A Stormy day on the Rock with Gale force winds and large swell running.
  • Sea lions rode out the winds in the ocean swells, rafting together in large moving masses or surfing in groups.
  • The two Bull Eseals stayed on the island.

Marine Vessels

  • Navy vessel on manoeuvres outside the reserve.
  • Accompanying Navy helicopters flying out from the ship over the reserve at night.

Maintenance

  • Some driftwood cleared from the boat launch ramp after the winds dropped.
  • Camera 2 re-set. Further investigation needed to resolve the network problem.

Other

  • Number of animals in the reserve was affected by the storm (and maybe the counting too due to conditions!).

How Low Can It Go?

Thick fog met me at dawn, not the sleepy kind that coffee cuts through, but dripping wet, zero visibility, fog created through the convergence of cold ocean water and warm air. The fog retreated and advanced repeatedly before it was beaten back by high wattage sunshine. The westerly wind blew throughout, at 5 – 15 knots only rising near sunset to closer to 20. The barometer started a gradual drop in pressure late morning yet the forecast is for sunshine and continuing westerlies.

There were a few whale watching boats in the area mid-morning with two observed in the Ecological Reserve. Sports fishing boats were seen in the general area but outside the Reserve.

The elephant seals found the trek to seawater quite an effort today and some of them gave up for a few hours on the way to have a swim. Getting back up the hill was even more of an effort.

The tide is a long way out.

The tide is a long way out.

Observational efforts were focused in the inter-tidal and on the mega-fauna census today. Another really good tide (0.5m) allowed me to do a large algal survey and find more marine invertebrate species. I will share some of the invertebrates here and come back to the seaweeds tomorrow. In each photo, if you look closely you will notice smaller and smaller animals in a wall to wall competition for space or is it sharing of space.

The human history and natural history are intertwined.

Both the natural and human history at Race Rocks are profound.

California Mussel beds are ‘old growth’ and substantial on Great Race. The large area provides important habitat creating significant diversity.

 

Extensive mussel beds on the south side of Great Race.

Extensive mussel beds on the south side of Great Race.

A brooding sea anemone (Epiactus prolifera) with numerous offspring attached low on the column near the pedal disc.

Epiactus prolifera

The mottled sea anemone (Urticina crassicornis) is quite common in the low inter-tidal on the south side of Great Race.

Urticina crassicornis

This species of tubeworm, named after Vancouver (Eudistylia vancouverensis) is usually more abundant sub-tidally. Here in the high current area between Great Race and South Islands, it is common in the low inter-tidal.

Eudistylia vancouverensis There is a lot of gigantism on the Pacific coast but here at Race Rocks even the giant species seem even more abundant and bigger than I have seen them elsewhere.

Cryptochiton

The gumboot chiton (Cryptochiton stelleri) is an important grazer in the inter-tidal. They are very abundant here.

Katharina

The Black Leather Chiton (Katharina tunicata) is another grazer and like the gumboot chiton grows both very large and is super abundant here.

 

Cucumaria Dodecaceria

Orange sea cucumbers (Cucumaria miniata) are really abundant both in tide pools and under the edges of boulders and there a lot of boulders on the south side.

 

Three species of sea urchin were observed today, adding the green urchin (Stronglyocentrotus drobachiensis) to the list. The green and purple both like to “dress-up” aka cover themselves, with shells, seaweeds and even bits of wood. Here they were using empty limpet shells in an area frequented by oystercatchers.

drobachiensis rostangia

Green and purple sea urchins with a small orange nudibranch to their left (Rostanga pulchra) that usually lives on the red sponge Ophlitasponge.
