Chris Blondeau and Juan Carlos do another video of the substrate at the site of the piling installation prior to the pile drilling operation for the Tidal Current Energy Project. They document some of the species of hydroid, colonial ascidian and sponges which grow on the giant barnacles in the area. March 29, 2006.
Note: The video pauses on each clump in order to have a better view.
