Paleo Channel System Polygon
The Paleochannel Ply (polygon) layer contains polygons delineating the interpreted boundaries of paleochannels existing under the surface of the seafloor within the respective study area. Paleochannels are remnants of river and stream channels that have been filled with sediments and overlain by younger units. Paleochannels and other subsurface geologic features are identified as a result of sub-bottom geophysical surveys and coring. The features gathered into this MMIS layer were acquired from multiple investigators and projects, whose research on or around the Outer Continental Shelf (OCS) was funded fully or partially by the Bureau of Ocean Energy Management (BOEM). Attribution consists of feature description, location, age, and identification properties associated with each study. 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.
