Jan 23, 2025 · Twenty-five miles offshore from Nome's gold beaches, natural gas now bubbles up through the ocean floor. Found by shipboard water sampling during 1976, the seepage is not the first sign of oil and gas near Nome. Oil films have been …

Potential interactions of oil and ice in Norton Sound by Seelye Martin; Sedimentary process and potential geologic hazards on the seafloor of the Northern Bering Sea by Hans Nelson;

The low ethane/propane ratio is indicative of gas from a liquid petroleum source rather than from nonassociated or biogenic natural gas. Preliminary data on the structural geology of Norton Basin lend support to the interpretation based on the hydrocarbon plume.

the St. George Basin, Norton Sound, Navarin Basin, lower Cook Inlet + Shelikof Strait, and Beaufort Sea areas, but none encountered commercial-grade hydrocarbon deposits. Additionally, one dry hole was drilled onshore on a federal lease in the National Petroleum Reserve AEaska. Six federal outer continental shelf

Unusual concentrations of dissolved two- to four-carbon alkanes were observed in the waters in Norton Sound in a localized area approximately 40 kilometers south of Nome, Alaska, in 1976. The hydro...

Offshore seeps were discovered the to late 19th century and gas explorations. the Red Sea, along the coast of New Zealand, and the Sea (Owen, 1975). seeps North America were reported as early as the late 18th Century. The best known offshore seeps North America occur the Santa Barbara Channel off California.

Submarine seepage of natural gas in Norton Sound, Alaska January 1, 1977 Unusual concentrations of dissolved two- to four-carbon alkanes were observed in the waters in Norton Sound in a localized area approximately 40 kilometers south of Nome, Alaska, in 1976.

Geochemical evidence of a submarine seepage of natural gas beneath Norton Sound was discovered during a 1976 environmental survey of petroleum hydrocarbon levels in waters covering Alaskan continental shelves.

records in Norton basin(Fig. 7) are quite different from theone associate d with thegas seep. They exhibit onlyslight reflector pull-downs at their rr,argins, and lackthe dramatic“wipe-out” appearance of the seep anomaly. Low frequency reflections at0.6, 0.9, and 1.2 seconds canbe trac~d across

During a 1976 survey of petroleum hydrocarbon distributions in the waters of Norton Sound, relatively large concentrations of dissolved C2-C4 alkanes were observed in a localized area approximately 40 km south of Nome, Alaska.
