1979, Open-File Report 78-1034
Well water with concentrations of arsenic and nitrate exceeding U.S. Environmental Protection Agency standards occurs sporadically throughout the hills north of Fairbanks, Alaska. The arsenic contamination has not been correlated with placer or other mining activity. The high levels of nitrate do not generally appear related to septic waste contamination....

Possible role of mantle-derived CO2 in causing two "phreatic" explosions in Alaska
I. Barnes, G.A. McCoy
1979, Geology (7) 434-435
Two "phreatic" maars in Alaska may have been created by the explosive release of carbon dioxide from a basaltic melt. Both the basalt of the maars and the observed CO2 (δ13C = -6.36‰) are inferred to have come from the mantle. © 1979 Geological Society of America....

Submarine seep of carbon dioxide in Norton Sound, Alaska
K.A. Kvenvolden, K. Weliky, H. Nelson, D.J. Des Marais
1979, Science (205) 1264-1266
Earlier workers have described a submarine gas seep in Norton Sound having an unusual mixture of petroleum-like, low-molecular-weight hydrocarbons. Actually, only about 0.04 percent of the seeping gas is hydrocarbons and 98 percent is carbon dioxide. The isotopic compositions of carbon dioxide (δ13CPDB = –2.7 per mil) and methane (δ13CPDB = –36...
Biogenic and thermogenic gas in gas-charged sediment of Norton Sound, Alaska
Keith A. Kvenvolden, C.H. Nelson, D.R. Thor, Matthew C. Larsen, G.D. Redden, J. B. Rapp, D. J. Des Marais
1979, Conference Paper, Proceedings of Eleventh Annual Offshore Technology Conference
Chemical and isotopic compositions of sediment gas from Norton Sound have been determined for near-surface, gas-charged sediments at two sites identified in acoustic profiles and bottom observations. At one site air-driven vibracorer penetrated sediment saturated with methane. The isotopic value suggests that the methane originated from active biological processes operating...
