USGS CMG T-1-67-BS Metadata

To study the size of the basins, character of the rocks, and structure
of the Bering shelf.

Continuous seismic-reflection profiles, sediment thickness, lithology,
age, gold analyses, texture, mineralogy, foraminifera.

Magnetic data and continuous seismic-reflection profiles were obtained
along nearly 1,800 km of track, concentrated mostly in the northern Bering Sea;
in addition, about 100 bottom samples and dredge hauls were taken.
Interpretation of deep-penetration seismic profiles revealed a series of deep
basins containing as much as 2,000 m of sediments. Dredge haul obtained shows
that the acoustic basement on the continental margin consists of turbidites of
late Cretaceous (Campanian) age. Rocks smapled by dredge hauls in the Pribilof
Canyon and boreholes offshore at Nome show that the thick sedimentary cover in 
the basins is mostly of Neogene age. Upper Miocene marine rocks are present at 
the continental margin, and upper Miocene or Pliocene marine sediments are
present off Nome. The size of the basins, character of the rocks, and abundance
of minor broad folds indicate that the Bering shelf has a large and entirely
unexpected petroleum potential.
