Mapping the extent of former channels (infilled and buried in the shallow subsurface) provides crucial information for a number of coastal and marine spatial planning applications that help select appropriate offshore construction sites and and plan sand/gravel mining operations. The Bureau of Ocean Energy Management (BOEM) can use this information when managing Outer Continental Shelf (OCS) non-energy mineral resources in order to ensure that the removal and relocation of sand is conducted in a safe and environmentally sound manner, and that any potentially adverse impacts on the marine, coastal, or human environments are avoided or minimized. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Paleochannel Arc layer contains lines that represent the boundaries and or central axes (thalwegs) of shallow subsurface paleochannels/paleovalleys interpreted from trackline geophysical data (e.g., seismic). Paleochannels are remnants of fluvial and estuarine channel systems that have been filled with sediments and overlain by younger stratigraphic units. 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) or partner agencies. 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.</SPAN></P></DIV></DIV></DIV> |
