This layer contains annotation about geomorphological features of the eastern Canterbury area. They describe landforms and surficial processes that have acted upon the area in the late Quaternary.

This collection of datasets comprises the 'Geology of the Hyde-Macraes Shear Zone and Waihemo Fault Zone area' 1:50 000 compilation of geological data covering a part of of East Otago and extending off shore to the Karitane Canyon.

Dunedin City in the South Island of New Zealand has many assets and critical infrastructure sitting on a low-lying coastal plain that is underlain by a largely unseen and relatively poorly understood hazard. Shallow groundwater in this area limits the unsaturated ground available to store rain and runoff, promotes flooding and creates opportunities for infiltration into stormwater and wastewater networks. Groundwater levels are expected to rise as sea level rises, causing greater frequency of flooding and/or direct inundation once it nears the ground surface. This zipped archive contains ArcGIS 10.8 geodatabases and spatial analysis of data gathered from a shallow groundwater monitoring network between 6/3/2019 and 1/5/2023. Data are licenced under Creative Commons Attribution 4.0 (CC-BY-4.0) licence without warranty. A series of statistical surfaces represent the present-day (2023) water table elevation and depth to groundwater, the response to rainfall recharge and tidal forcing, the available subsurface storage of rain infiltration. Simple geometric models have also been developed using the present shape and position of the water table, combined with tidal fluctuations, to forecast the future state of groundwater levels at 10 cm increments of sea level rise (up to 1 m). The geometric models are strongly empirical, with many implicit assumptions and caveats – particularly, that they do not account for groundwater flow and possible changes in water-budget mass balance. Although many variables and controlling processes are simplified into a single parameter, the projected groundwater levels highlight how local variations in the water table shape and slope interact locally with the ground elevation or infrastructure networks. They are best considered as a worst-case analysis of groundwater-related contribution to hazard and how this will evolve over time. Further description of these data, and implications from the analysis, can be found in Cox et al. (2023) GNS Science Report 2023/43 doi:10.21420/5799-N894.

This layer contains geomorphological boundaries of the eastern Canterbury area. Its features describe landforms and surficial processes that have acted upon the area in the late Quaternary.

This collection of datasets comprises geological information for Antarctica. They have been compiled by the GeoMAP team led by GNS Science. This work utilsed co-funding from GNS Science's Nationally Significant Databases and Collections Programme (NSDC) and international collaboration through the SCAR GeoMAP project. It represents a synthesis of existing published and unpublished mapping of the geology of this area in a single geodatabase at a regional scale. The data comprises geological unit polygon geometry and attribute fields describing the unit type, name, age, lithology, stratigraphy, and supporting background information, where this is known and geological fault polyline geometry and attribute fields describing locational accuracy, exposure, fault type, and supporting background information, where this is known.

The collection of datasets describes the geology of the eastern Canterbury area.

The collection of datasets describes the geology and geomorphology of urban Christchurch and eastern Canterbury. Following the 2010-2012 Canterbury Earthquake Sequence the Christchurch area was the focus of an unparalleled investigation of subsurface ground conditions, resulting in extensive acquisition to drillhole, geotechnical and geophysical data. These new data have been combined with legacy information including logs that describe more than 12,000 wells drilled for groundwater, one of Christchurch's most valuable resources.

This collection of datasets comprises geological information for Antarctica. Data have been compiled by the GeoMAP team led by GNS Science. Version 2022-08 updates an early beta version (v.2019-07) in response to informal feedback and peer review, and/or the need for local improvements. GeoMAP has utilsed co-funding from GNS Science's Nationally Significant Databases and Collections Programme (NSDC) and international collaboration through the SCAR GeoMAP project(2015-2020). It represents a synthesis of existing published and unpublished mapping of the continent's geologyin a single geodatabase at a regional scale. The data comprises geological unit polygon geometry and attribute fields describing the unit type, name, age, lithology, stratigraphy, and supporting background information, where this is known and geological fault polyline geometry and attribute fields describing locational accuracy, exposure, fault type, and supporting background information, where this is known. Data are linked to the source polygon geometry which provides a spatial bibliography of key datasets and maps used in their compilation. The data structures within this geodatabase comply with the GeoSciML 4.1 standard where relevant and uses the relevant CGI Controlled Vocabularies.The GeoMAP dataset was produced as part of the Regional Geological Map Archive and Datafile, one of the Nationally Significant Collections and Databases supported by the New Zealand Government’s Strategic Science Investment Fund (contract C05X1701).DOI https://doi.org/10.21420/7SH7-6K05
