Survey Requirements: • Multibeam: 100% coverage below LWT (bathymetry AND backscatter) Special Order to 20 m Order 1 thereafter • Datums: horiz. : WGS 84, vertical: CHS Chart datum • Sidescan : search for targets amongst moorings reconnaisance of intertidal zone • Subbottom : 50 m line spacing (28 k. Hz and 3. 5 k. Hz) • ADCP : GGE 5083 Hydrogrpahic Field Operations time series over full tidal cycle for E and W harbour entrances Multibeam, Sidescan and Subbottom all collected within 2 hours of HW. © J. E.
