Bounty and Antipodes Islands Multibeam 30m Depth Model (2005)
This layer contains depth information in gridded format captured by multibeam sonar in 2005 as part of P3001 - Bounty and Antipodes Islands Hydrographic Survey.
The data was collected for Toitū Te Whenua Land Information New Zealand (LINZ) and for which the survey took place from 25 March to 8 April 2005. Data management and distribution is by LINZ.
Data comprises a gridded depth model as tif or ascii tiles in UTM projection.
Vertical accuracy is +/- 1.14m (95%)
Horizontal accuracy is +/- 3.04m (95%)
Vertical datum is Approximate Lowest Astronomical Tide.
The source data used to create the depth model may be of a higher resolution/density than the model. This data can be supplied on request and available resolutions be discovered through the [NZ Bathymetric Surface model Index]( https://data.linz.govt.nz/layer/95574-nz-bathymetric-surface-model-index/ ).

Toitū Te Whenua Land Information New Zealand (Toitū Te Whenua) carries out seabed surveys that meet the standards required to produce and update nautical charts for marine navigation safety. We use ship- and aircraft-mounted sensors that use sound (echo sounders) or light (LiDAR) to map the contours of seabed.
Seabed survey data can also be visualised as detailed 3D maps that provide valuable information. Communities, businesses, and local and central government can use this data for flood modelling, aquaculture development, marine research and much more.
A seabed map describes the shape of the seafloor like a topographic map of land. Terrain attributes like slope and rugosity can also be generated. Toitū Te Whenua also collects data on the strength of the return signals from the echo sounders which can give information about the ocean floor and is a key dataset for habitat mapping. In addition, the water column reflectance is recorded which can be used to identify features above the seabed like algae, wrecks, gas plumes or schools of fish.
Additional sensors can be deployed to collect information about currents, water temperature, salinity, density and acidity. These factors can influence the biodiversity and species abundance, which are of interest to ecologists. It can also be used by councils to refine mooring or anchorage areas, update consents for shoreline infrastructures or help assess coastal erosion for monitoring and planning purposes.
