These surveys are complementary to a similar continuing series of Green Sea Urchin surveys conducted in Queen Charlotte Strait, originating in October 1995. Data were collected by SCUBA divers using the transect-quadrat method, and include information on size and abundance of Green Sea Urchins, gonad weight and quality, and on the depth and substrate. The long-term objectives are to assess variability in Green Sea Urchin populations over time to monitor harvest impacts"--Abstract, p. vii.
