Abstract: During a 17-day period in February 2002 GNS and Otago University undertook a Global Positioning System (GPS) survey in the central South Island, consisting of two campaigns labelled AP2002 and CSI2002. The CSI2002 campaign was intended to fully repeat the observations made in earlier “Copland/Rangitata” campaigns during February 1996 and February 1998 We succeeded in reoccupying all but a few of these earlier GPS sites. For some of the sites this campaign represents a fourth occupation, as some observations were also made by DoSLI in 1996 and GNS/Otago University/Oxford University in 1994. We also observed a number of sites towards the western end of the Arthur’s Pass GPS network, which we denote the AP2002 campaign. This was partly to obtain extra data at sites whose velocities appeared anomalous relative to nearby sites, and partly to install new stations in the vicinity of the western Hope fault. This report documents the survey, describing the logistics of the two campaigns, the sites occupied and the data collected. (auth)
