J., and Gartman, A., 2024, Global ferromanganese crust and abyssal ferromanganese nodule prospective occurrence regions: U.S. Geological Survey data release, https://doi:10.5066/P13R3J6J. Online_Linkage: https://doi.org/10.5066/P13R3J6J Description: Abstract: This data release is a polygon shapefile representing prospective occurrence regions of ferromanganese crusts and abyssal ferromanganese nodules on the seafloor throughout the global oceans. Polygons represent areas where oceanographic criteria, such as low sedimentation rate and moderate primary productivity, overlap with geologic criteria, including regions with appropriate seafloor morphology for each mineral type, such as seamounts and ridges or abyssal plains. The regions indicate where ferromanganese crusts and abyssal ferromanganese nodules are likely to occur but do not indicate whether minerals have been found in these regions, nor do they indicate the presence of a mineral deposit. Purpose: This work was funded by the U.S. Geological Survey (USGS ) Coastal and Marine Hazards and Resources Program through the USGS Pacific Coastal and Marine Science Center, and in part by the U.S. Department of the Interior, Bureau of Ocean Energy Management through Interagency Agreement M19PG00021 with the USGS. These shapefiles were created as part of the USGS effort to understand geologic and oceanographic processes that lead to the formation of marine minerals and where marine mineral resources occur. An area designated here as prospective does not mean that the region hosts marine minerals, and it does not indicate that the marine minerals occurring in that region will be economically viable. Regions not meeting the criteria for prospective designation are not included here. These regional outlines are intended to provide baseline information regarding where marine minerals are likely to occur throughout the global ocean, for use by scientists, resource managers, and the general public. The data can be used with geographic information systems (GIS) software for research purposes.

Although this Federal Geographic Data Committee-compliant metadata file is intended to document the dataset in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.

Logical_Consistency_Report: No additional checks for consistency were performed on this data. Completeness_Report: Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Prospective indicates that a region is consistent with the geologic and oceanographic criteria required to potentially host marine minerals. This does not mean that a region hosts marine minerals, and it does not indicate that the marine minerals occurring in that region will be economically viable. Regions not meeting the criteria for prospective designation are not included here. These regional outlines are intended to provide baseline information regarding where marine minerals may occur. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. Locations are based on consideration of global scale maps showing overlapping criteria listed in process steps.
