Occurrences of Oil and Gas Seeps Along the Gulf of Alaska.
8th Ann Offshore Tech Conf Houston Tex 1976 May; :211-220
Oil seeps on portions of the Alaska Peninsula and the northcentral Gulf of Alaska were investigated by the federal Bureau of Mines to determine (1) whether previously reported seeps are still active, (2) the characteristics of the seeping hydrocarbons, and (3) the amount of bitumen contained in the drainage leaving the seeps and entering the Gulf of Alaska waters. Eighteen oil seeps, 7 bitumen deposits, and 12 gas seeps were located. In all, 102 samples of water were obtained from seep locations and seep drainages. Water samples associated with the seeps were analyzed for ionic content by solvent extraction for hydrocarbon content. Analyses confirmed that although the water at the oil seep sites sometimes contained high bitumen content, the amount of hydrocarbons actually reaching the Gulf of Alaska waters from the seeps is minimal.
