| 520 | 3 |a"Systematic mapping of the Chatham Sound region, British Columbia, shows that hexactinellid sponge reefs are a significant component of the seafloor mosaic. Based on the three criteria for reef identification (positive relief, low backscatter strength, and acoustic transparency) it is shown that the total reef area is 48 km2. The largest cluster of identified reefs is located within Chatham Sound sensu stricto and covers more than 27 km2 of seafloor in water depths of 35-170 m. It includes reefs up to 25 m high and is designated the Chatham Sound reef complex. The authors describe some of the wide range of morphologies in this reef complex and the nearby reefs”--Abstract, p. 1. |
