Isopach Contour
The Isopach Arc layer contains contour lines, or isopachs, that represent positions of equal formation thickness of a sand body, or other geologic unit, with the thickness being measured vertically with respect to the seafloor. The investigations from which these geospatial data were derived were fully or partially funded by the Bureau of Ocean Energy Management (BOEM) or former Minerals Management Service (MMS). Attribution consists of location, feature ID and description, study date, contour value (thickness), and study ID. The associated study report(s) are linked via the related Link Documents table within the Marine Minerals Information System (MMIS) geodatabase. This dataset will be updated as new and existing data are received and incorporated in to the Marine Minerals Information System (MMIS) geodatabase.
