This report summarises the survey results and assessments of the eight specific sites, and makes comparisons of the benthic abundance and diversity and substrate characteristics among sites. The Seabed Ecology Studies form part of an ongoing series of marine monitoring studies designed to address the cumulative impacts of dredging and disposal projects on the marine environment of Hong Kong. The Studies were both a continuation and refinement of previous soft-bottom ecological surveys, with specific Study tasks outlined in eight different areas of Hong Kong waters, including:
- open water disposal sites: East of Ninepins and South Cheung Chau;
- marine borrow areas: Tathong Channel, the Sokos, Eastern Waters;
- ambient reference areas: Basalt Island and South Lama;
- backfilled marine borrow area: East Sha Chau; and,
- far field reference areas associated with each of these sites.
The broad objective of the Studies was to provide a clearer understanding of the environmental impacts of dredging and disposal activities.
