Online_Linkage: https://doi.org/10.5066/P1KXSYGD Description: Abstract: This shapefile is of prospective regional outlines of where marine minerals may occur on the Alaska Outer Continental Shelf (OCS). Polygons were hand digitized based on a U.S. Geological Survey (USGS) data review that considers the state of knowledge regarding marine mineral occurrences within the Alaska OCS. This data release is a companion to the USGS Professional Paper, Gartman and others, 2022. Purpose: This work was funded by the 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 polygons are of prospective regions for the potential occurrence of ferromanganese crusts, manganese nodules, and hydrothermal minerals for the marine areas surrounding Alaska, specifically the Alaska Outer Continental Shelf (OCS). In this study we review areas, prospective for deep-ocean minerals in the Alaska OCS to identify regions, where "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, for use by scientists, resource managers, and the general public. The data can be used with geographic information systems (GIS) software for research purposes.

Process_Step: Process_Description: Global and regional oceanographic and geologic spatial datasets were compiled and visually overlaid to determine regions meeting all the known criteria for ferromanganese crust formation (hard rock substrate on seamounts, low sedimentation rate), and abyssal manganese nodule formation (flat and sediment-covered basins, low sedimentation rate, low to moderate primary productivity, depths below the carbonate compensation depth, seafloor lithology), and hydrothermal minerals (along active arc, including extensional regions).

Areas were outlined that met all the formation criteria for each mineral type and were refined based on where samples were collected that confirmed the presence of marine minerals as well as specific criteria in each region as follows: 1) in the Gulf of Alaska Seamounts, areas prospective for ferromanganese crusts are at water depths shallower than 3,000 meters (m) (or 2,850 m where the abyssal plain doesn't reach 3,000 m); below 3,000 m, thick ferromanganese crusts are less likely to occur due to higher sedimentation rates and distance from oxygen minimum zones (OMZ) that are a reservoir of dissolved manganese; 2) for Chukchi Borderland, regions prospective for ferromanganese crusts are between water depths of 300 and 2,800 meters (m), except on the eastern flank of the Northwind Ridge where prospective depths extend down to 3,800 m, owing to steep slopes that prevent sediment accumulation; 3) for manganese nodules in the Gulf of Alaska, areas prospective for manganese nodules are at water depths of 3,800 m or deeper, where the Canada Basin Abyssal Plain is deepest, flattest, and undergoes the lowest sedimentation rates; 4) for the Aleutian Arc, the arc is prospective for hydrothermal minerals, specifically potential extensional regions. Prospective regions were converted to shapefiles in ArcGIS software for each mineral type for use in GIS applications such as maps, modeling, or other.
