Hydrocarbon seep locations and compositions have been used in prospecting for oil and gas fields. It has been observed that the compositions of hydrocarbon seeps can be a direct indicator of hydrocarbons filling a subsurface prospect. The primary goal of this desktop study is to help BOEM evaluate the potential for offshore petroleum resources in the Lower Cook Inlet, Gulf of Alaska, Chukchi Sea and Beaufort Sea Outer Continental Shelf. Patterns of seep occurrence on the seafloor provide insights into the geologic history, materials, and subsurface structures, improving our geological understanding of the Alaska offshore region. This study developed a geodatabase with the locations and metadata for 1,486 seeps identified from available literature, publicly available seafloor and water column data, and BOEM documents. The geodatabase also includes publicly available geophysical data that were used in interpreting the spatial distribution of the seep locations.
