Abstract: The Kupe mapping area (KUP) is the first of seven offshore regions to be mapped on digital seismic reflection profiles as part of the GNS Science “4D-Taranaki Project”. This report provides an overview of this mapping and interpreted subsurface stratigraphy and structure in the Kupe mapping region. Within the KUP area, 17 seismic horizons have been identified and mapped on an allostratigraphic basis, i.e., stratigraphic units are defined on the basis of observed bounding discontinuities. This document describes the seismic reflection character of these horizons and their associated sequences. The 17 seismic horizons have been gridded and mapped as time-structure surfaces. They have also been depth converted to derive a set of depth-structure maps as well as a set of 16 isopach maps. A selection of isopach maps are appended to this report and, together with the time-structure and depth-structure maps. Also included are figures showing the coverage of seismic and well data, as well as four cross-sections. The entire set of time-structure, depth-structure and isopach maps from the Kupe mapping area maps plus the digital grids and GOCAD triangulated-surfaces (t-surfaces) of the mapped horizons are additionally available for purchase. In combination with an analysis of seismic facies character, the map suite provides a more detailed overview of the structural evolution and depositional history in the KUP area than previously existed.
