Database of lake core and sample metadata from Lakes380, past, present, future programme (MBIE endeavour 2017-2022). • To use and collaborate on research relating to environmental change and lake health captured in lake cores. • Location and sample information including physical location and core subsampling. Linked back to core sample depth and number. • Metadata of the history of the analysis, including processing, handling, and analysis. DOI: https://doi.org/10.21420/PBNM-5X75 Cite as: GNS Science.

New Zealand Active Source Seismic Data Resource a national archive which holds data and interpretation derived from active-source seismic investigation within the NZ ECS. It contains data from both commercial exploration and research experiments. It is managed as a collection of datasets.

A database of geophysical logs derived from NZ boreholes (and derived velocity/time curves). It includes both digital and paper records

This layer contains depth information in gridded format captured by multibeam sonar in 2005 as part of P3001 - Bounty and Antipodes Islands Hydrographic Survey. The data was collected for Toitū Te Whenua Land Information New Zealand (LINZ) and for which the survey took place from 25 March to 8 April 2005. Data management and distribution is by LINZ. Data comprises a gridded depth model as tif or ascii tiles in UTM projection. Vertical accuracy is +/- 1.14m (95%) Horizontal accuracy is +/- 3.04m (95%) Vertical datum is Approximate Lowest Astronomical Tide. The source data used to create the depth model may be of a higher resolution/density than the model. This data can be supplied on request and available resolutions be discovered through the [NZ Bathymetric Surface model Index](https://data.linz.govt.nz/layer/95574-nz-bathymetric-surface-model-index/).
