This EnviroAtlas dataset is a digital hydrologic unit (HUC) boundary layer to the Subwatershed (12-digit) 6th level for Puerto Rico, based on the May 2016 NHDPlus V2.1 WBD (Watershed Boundary Dataset) Snapshot for Puerto Rico & U.S. Virgin Islands. Information on the percent land area has been added, and HUCs for Puerto Rico and the Virgin Islands have been split into two separate files. The location of one HUC (a small island) has been adjusted to align with aerial imagery and GAP (Gap Analysis Program) land cover data. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).

This Feature Class contains polygon features that summarise the exploration potential of the Miocene succession within sedimentary basins in the Northwest Province (Taranaki, Deepwater Taranaki, and Reinga-Northland basins). Areas where all of the requirements for oil or gas accumulation are present are indicated as having high exploration potential. Areas where all the requirements are not optimum, but may be present are indicated as areas of moderate exploration potential. Areas of low exploration potential indicates that on the basis of currently available open-file information there is a high risk for one or more of the petroleum systems elements not being able to effectively contribute to the petroleum system in that area. It is important to note that a rating of low exploration potential does not conclusively rule it out; rather, there is a high degree of uncertainty associated with presence of one or more of the petroleum system elements. For any given prospective area, more detailed work and data acquisition would be required. For more information about these data please refer to: Arnot, M.J. and Bland, K.J. et al. (Compilers), 2016.

This Feature Class contains paleogeographic structural polyline features for sedimentary basins in the Northwest Province (Atlas of Petroleum Prospectivity), namely the Taranaki, Deepwater Taranaki, and Reinga-Northland basins. Features are depicted relative to the modern New Zealand coastline. No palinspastic reconstructions have been undertaken. Polygon features for 98 Ma (mid-Cretaceous, NZ Ngaterian Stage) are contained in this Feature Class.

This layer comprises the faults datafor Antarctica. It represents a synthesis of existing published and unpublished mapping of faulting in this area in a single dataset at a regional scale. While it includes some structures interpreted from geophysical datasets, or inferred from continental-scale syntheses, the focus has been a capture of data from geological observations and geological mapping. The dataset comprises arcs with each arc having attributes describing the locational accuracy, exposure, activity, type of fault, and the sense of movement of the fault, where this is known. This layer complies with the GeoSciML Lite standard for ShearDisplacementStructureView and fields required by that standard were populated using the CGI Controlled Vocabulary (v2016.01).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

This Feature Class contains contours that depict the interpreted depth below sea level (in metres) to the Basement seismic horizon, in 500 m intervals, as mapped within the Northwest Province of the Atlas of Petroleum Prospectivity (namely the Taranaki, Deepwater Taranaki, and Reinga-Northland basins). For more information about the seismic horizon naming scheme used in this project please refer to: Strogen, D.P.; King, P.R. 2014. A new Zealandia-wide seismic horizon naming scheme. Lower Hutt, NZ: GNS Science. GNS Science report 2014/34. 20 p. The depth grids, from which these contours were derived, were generated in Paradigm 2015 SeisEarth software using an adaptive fitting algorithm and a grid resolution of 1 km x 1 km. Faults have not been incorporated into the regional-scale gridding of either the TWT or depth maps in this project. The depth grids were then exported from SeisEarth (Zmap format), checked for internal consistency in Zetaware (Trinity 4.61), edited as needed to account for gridding errors and then exported as ArcView Ascii grids, imported and contoured with Esri's ArcGIS software. Due to its large depth range the Basement horizon has been contoured at both 250 m and 500 m intervals. For more information about the depth conversion and gridding process used, please refer to: Arnot, M.J. and Bland, K.J. et al. (Compilers), 2016. Atlas of Petroleum Prospectivity, Northwest Province: ArcGIS geodatabase and technical report. GNS Science Data Series 23b. Given the considerable variability in the spacing and density of 2D seismic data over the entire NWP area the "smoothness" of the depth maps varies accordingly. In the central Taranaki Basin, where seismic line spacing may be 5 km or less, the 1 km x 1 km grid resolution captures the geological complexity well. However, in areas of the NWP such as the Deepwater Taranaki Basin to the west and Reinga Basin in the north, seismic line spacing may be in the order of 15 to 30 km. In such areas the underlying geological complexity is only captured where seismic interpretation exists along the available 2D seismic lines.

This layer shows the interpreted surface locations of active plate and microplate boundaries, in and around Te Riu-a-Māui / Zealandia. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

This layer is a geological map bibliography for Antarctica. It was produced by GNS Science in conjunction with partners in the SCAR GeoMAP project. It represents the sources referred to in the classification of geological map polygons. This layer depicts a selection of key maps, as polygon outlines with data providing links to original bibliographic source, that have been useful to the GeoMAP team (as at June 2019). It shows the majority of, but not necessarily all, geological maps available for Antarctica. The dataset comprises polygons with each having attributes describing the source's authors, title, publication, year, program and scale of publication. The data structure complies with the GeoSciML 4.1 standard where relevant and uses the relevant CGI Controlled Vocabularies.

This Feature Class contains Common Risk Segment (CRS) polygon features for denoting the risk of reservoir rocks being absent at the 66 Ma (latest Cretaceous) level in sedimentary basins in the Northwest Province (Taranaki, Deepwater Taranaki, and Reinga-Northland basins). Risk is depicted by a relatively simple "traffic-light" system: green colours denote low risk, orange denotes moderate risk, and red colours denote high risk. It is important to note that a rating of high risk (red) for this petroleum systems element does not conclusively rule it out; rather, it indicates that on the basis of currently available open-file information there is a high risk for that factor being able to effectively contribute to the petroleum system in that area. For any given prospective area, more detailed work and data acquisition would be required. For more information about these data please refer to: Arnot, M.J. and Bland, K.J. et al. (Compilers), 2016.
