Digital Terrain Models:
Compilation of echo-sounder and other bathymetry data by M. Dunkin
Areas A soundings allowed a 1m grid size,
Area B soundings allowed a 10m grid size,
Area C is a 10m grid based on the NIWA Coastal Bathymetry Database
using 10m contour lines where available (generally at depths less than
100m), elsewhere 50m contour data.
All shaded relief grids have x5 vertical exageration.

Data Collection:
Nearshore launch surveys using echo-sounder, side-scan sonar, Uniboom
seismic system and grab sampler, with positioning by differential GPS
in April and December 1996 and LINZ Hydrographic Survey, January to
April 1998. Deep water swath survey from French (IFREMER) RV L'Atalante
using Simrad EM 12D swath mapping system in November, 1993. Coastal
and shore platform morphology from aerial photographs. Other seismic
reflection data, soundings, and samples from R.V. Rapuhia surveys
1988-1992, and from published and archived bathymetric, scientific and
industry sources.
