Chris Blondeau and Juan Carlos video the substrate at the site of the tidal energy piling installation. This is prior to the pile drilling operation for the Pearson College-ENCANA_Clean Current Demonstration Tidal Current Energy Project. They find bedrock in the area 30 cm under the surface at a depth of 24 meters of water.

Henry Steinberg, Julia Clarke and Laura Verhegge do their first tether dive with Chris off the shores of Race Rocks in Race Passage. The apparatus for the dive was constructed by Henry Steinberg, a Pearson College diver, as part of a project in his PADI Divemasters course. This type of diving is useful for research purposes when one wants to sample jellyfish, salps or other macro-planktonic life forms which may otherwise be damaged if collected in a towed plankton net. It is also necessary as a safety measure for drift diving when the bottom is beyond safety limits, and there are currents involved such as here in the Strait of Juan de Fuca.
This video shows the installation process for the tidal energy generator research project. This was carried out by Chris Blondeau and the Pearson College Divers in order to determine which surfaces discouraged growth in the waters at Race Rocks. As a result, Titanium was used in the construction of some parts of the generator as it was one of the metals most resistant to fouling.
