On June 22, 2008, the Black Oystercatcher nest which was located on the rock just above the docks produced two chicks. They hatched in the morning and this set of clips was taken from a screen capture of camera 3 in intervals between 4:00 PM to 5:30 PM. They returned to spend the night at the nest, and left the next morning.

| Procedure 1 | Dec 7, 2007– Purpose: To test performance and resistance to fouling of PVC junction boxes and sealant compounds |
| Procedure 2 | Jan 10, 2008– Purpose: to test resistance to fouling and corrosion of different alloys of Stainless Steel as well as various types of fasteners. |
| Procedure 3 | Purpose: to protect submarine cables from chafing on sharp rocky edges |
| Procedure 4 | Purpose: To prevent corrosion of steel Ibeam supporting and holding power and control cables through intertidal zone. |
| Procedure 5 | Purpose: To provide ballast to steel Ibeam carrying power cables in intertidal zone preventing movement during heavy surge. |

| Against the rock wall above the original concrete foundation of the old engine room, and below the tower, a group led by Hannah and Giovanni on one Project week did the digging out of soil, and replacement with crushed rock. . | This allowed the creation of a natural looking corner for the old historic engine room equipment. In this photo Hannah is on the bucket brigade carrying gravel. |

| Sylvia and Alex Chan examine the old engine parts. | Looking straight down from the tower on the east side, one can see the concrete pathway which we believe went to the blacksmith shop. | In the past, many old pieces of equipment were simply pushed over the side. | In 2006,the old boiler which lay rusting in the intertidal zone for many years was starting to break up. |

 |
| The storms in the winter of 2006 dispersed the parts of the boiler | These pieces which are now small enough to move will be transferred to the collecting area. | The other end of the boiler. This was carried up to shore on February 12, 2007 by members of the racerocks.com activity.See below. | The hurricane in December 2006 moved rocks exposing more rubble below the energy building. |

The last of the rusted parts of the old boiler from the engine room shown above are carried up by Pearson College students in the Race Rocks Activity in 2007 to be part of the collection of other old parts stored at the base of the tower.
This video is a compressed version of the one produced by Brainstorm for the Tidal Current Power Project. It documents the partners and the process along the way in the establishment of the Turbine Project . (released January 19, 2007 to correspond with the visit of Prime Minister Stephen Harper to Lester Pearson College and Race Rocks.)
This video was taken with the remote camera 5 on Dec 11, 2006, a day which can be represented by the images of the atmospheric factors below. Note the wind speed was over 40 knots in the afternoon. The extreme pressure drop on the barometric graph was a good indicator that a big wind was coming.
It certainly can be seen as a wild mixture of weather for the day.
This video was taken in the lab:

II took this picture the first time I encountered this ascidian when diving at Race Rocks. I had no idea what kind of organism it was at the time .. I referred to it as a grape ascidian .. GF

Brant’s cormorants: Phalacrocorax penicilatu -photo by Alex Fletcher
This cormorant is numerous in the winter, with much of the British Columbia population present at that time, as it is a relatively rare bird. In 1987 a survey that reported 3 nests was done on 15 July by Wayne Campbell and was reported in: Campbell, R.W., and Preston, M. 1988. British Columbia nest records scheme. Thirty-first and thirty-second annual report 1986-1987. British Columbia Naturalist 26:12-13.
Here are the links to the Christmas Bird Counts.
In 2014 and for several years previous, there have been no cormorants nesting at Race Rocks. The only still-thriving colonies are at Mandarte Island.
This is a Blue-listed species in BC. This list includes species not immediately threatened, but of concern because of characteristics that make them particularly sensitive to human activities or natural events.

Ryan Murphy photo of this species.
In this video, the soft pink coral Gersemia rubiformis is highlighted. It grows at 7-10 meters over a 3 square meter area off peg #3. Other organisms shown in association in the same area are: Anemone- (both Tealia and Epiactis), hydroids, sponges and colonial ascidians .
Urticina grebelnyi
Painted Anemone
Urticina grebelnyi has previously been called ” Tealia” anemone. They are one of the most abundant large anemone at Race Rocks in the subtidal area. They use their nematocysts expelled from their stout tentacles for the immobilization of small fish, crustaceans such as krill and anything organic that drifts their way. Pieces of dead fish have been seen clinging to the tentacles. They are believed to live a very long time, as long as they are in an area well supplied with food by the current.
