Chatham Rise Bathymetry Poster

This chart of the Chatham Rise incorporates all NIWA's available bathymetric data from a wide variety of sources, including recent multibeam 'swath' data. It is the first time such a detailed map has been produced of this area, and its resolution is able to display small seamount-like features which are important for deepwater fisheries on the Rise. 3-D graphics are produced for two such fishing grounds where these features host aggregations of orange roughy. The map was produced under NIWAs FRST-funded programme 'Seamounts: their importance to fisheries and marine ecosystems'. The poster is approximately 100 cm x 70 cm.
