New Zealand Hikurangi Margin temperature and pressure loggers - data sets.

Description of data

In 2019, 14 RBR data loggers were purchased as a supplement to an existing NSF grant, and were tested, calibrated, and deployed on the Hikurangi Subduction Zone margin as part of the Evan Solomon (UW) deployment of flow meters at this site. The purpose of the Solomon pore fluid analysis program was to determine the impact of Slow Slip Tectonic Events on near-surface fluid flow for this active margin. The purpose of the supplemental RBR loggers, attached directly to fluid flow meters, was to add the key components of pressure and temperature to this data set and specifically to identify any sediment slope failures and turbidity flows that occur during the two year deployment period.

By May 6, 2021, all of the Solomon flow meters have been recovered with the attached UW supplemental RBR loggers.  The loggers were be subjected to a final ice bath calibration test prior to data-download in New Zealand and all T/P data will be returned to UW via internet. The physical data loggers were then be returned to UW via air freight.

The data in these Zenodo data archive files include all of the pre-cruise and post-cruise calibrations fro the RBR T/P loggers, the raw and calibrated data, and the locations of the stations.  Also included are some infrastructure information including a multi-channel seismic profile showing that locations on the Hikurangi margin with known fault zones, and a published catalogue of earthquakes that occurred during the logger deployment period.
