Across-shelf mooring array from the northeast shelf of New Zealand

DOI

Five cross-shelf oceanographic moorings (M1 - M5) were deployed along Topex/Poseidon 147 line in water depths spanning 80to 1865 m (Fig. 1a). The stations, M1 (80 m depth) and M2 (130 m) were on the continental shelf, M3 (438 m) the shelf break,M4 (1105 m) the continental slope, and the most offshore M5 (1865 m) on the continental rise. The deployments lasted longerthan a year and the measurements overlap between 11/5/2015 and 15/5/2016. A total of 46 instruments were installed in the array of moorings (Fig. 1). Long Range (LR) acoustic Doppler current profilers (ADCPs) (75Hz) were deployed at stations M3, M4, and M5, and 4 Workhorse (WH) ADCPs (300 or 600Hz) were installed near the bottom at M1 and M2, and near thesurface at M4 and M5 and covered the water column shown in red and blue in Fig. 1b. The water column was binned every 4 m(WH) or 15 m (LR) by upward looking ADCPs. All the stations, except M1, had between 4 and 10 SBE 56 temperature sensors (black dots in Fig. 1b) and 2 or 3 MicroCAT CTDs (green circles in Fig. 1b). The temperature sensors were deployed every 10m in the upper 100 m and then every 50 m below that. M2 and M3 had CTDs placed near the surface and bottom, whereas M4and M5 had additional CTD at 200 m depth. Velocity (temperature and salinity) measurements were taken during a period of 2min. (1 min.) every 10 min or less.
