  New Zealand Regional Bathymetry

Bathymetric contour data set 50m - 12,000m around the New Zealand region.Published Chart: CANZ Group (2008), ‘New Zealand Region Bathymetry’,1:4,000,000 scale at 46°S on Mercator projection, NIWA Chart, Miscellaneous Series No. 85, National Institute of Water and Atmospheric Research, Wellington, New ZealandGeographic Coverage: In the edgematching of this sheet with GEBCO sheet G.08, the bathymetry was taken from sheet G.08 for the following areas:24°-31°S,157°-158.5°E; 47°-54°S,157°-165°E; 54°-57.5°S,157°-163.5°E The bathymetry was compiled by NIWA at a scale of 1:1 million using a series of 18 separate Ocean Plotting Sheets on which the soundings were plotted. Each author (as listed above) worked on the interpretation and contouring of 3-4 sheets each and gravity data were used to assist in the interpretation. The resulting contours (at intervals of 250m) were then digitized and used in the production of the 1:4 million scale chart. The bathymetry was compiled from data held at:National Institute of Water and Atmosphere (NIWA) Hydrographic Office of the Royal New Zealand NavyUS National Geophysical Data Centre South Pacific Applied Geoscience Commission (Fiji);from published scientific papers; and from recent swath bathymetric surveys funded by Institut Francais de Recherche pour l’Exploitation de la Mer (IFREMER), France, NIWA and Seabed Mapping New Zealand Ltd.The shallow water contours (50m, 100m, 150m and 200m) were compiled from a database made up of the digitized contours from the NIWA coastal (1:200,000)chart series.

Statement

Published Chart: CANZ Group (2008), ‘New Zealand Region Bathymetry’,

1:4,000,000 scale at 46°S on Mercator projection, NIWA Chart, Miscellaneous Series No. 85, National Institute of Water and Atmospheric Research, Wellington, New Zealand

Geographic Coverage: In the edgematching of this sheet with GEBCO sheet G.08, the bathymetry was taken from sheet G.08 for the following areas:

24°-31°S,157°-158.5°E; 47°-54°S,157°-165°E; 54°-57.5°S,157°-163.5°E

The bathymetry was compiled by NIWA at a scale of 1:1 million using a series of 18 separate Ocean Plotting Sheets on which the soundings were plotted. Each author (as listed above) worked on the interpretation and contouring of 3-4 sheets each and gravity data were used to assist in the interpretation. The resulting contours (at intervals of 250m) were then digitized and used in the production of the 1:4 million scale chart.

The bathymetry was compiled from data held at:

National Institute of Water and Atmosphere (NIWA)

Hydrographic Office of the Royal New Zealand Navy

US National Geophysical Data Centre

South Pacific Applied Geoscience Commission (Fiji);

from published scientific papers; and from recent swath bathymetric surveys funded by Institut Francais de Recherche pour l’Exploitation de la Mer (IFREMER), France, NIWA and Seabed Mapping New Zealand Ltd.

The shallow water contours (50m, 100m, 150m and 200m) were compiled from a

database made up of the digitized contours from the NIWA coastal (1:200,000)

chart series.
