Geology and petroleum potential of the Eurasia Basin Available to Purchase
Abstract The Eurasia Basin petroleum province comprises the younger, eastern half of the Arctic Ocean, including the Cenozoic Eurasia Basin and the outboard part of the continental margin of northern Europe. For the USGS petroleum assessment (CARA), it was divided into four assessment units (AUs): the Lena Prodelta AU, consisting of the deep-marine part of the Lena Delta; the Nansen Basin Margin AU, comprising the passive margin sequence of the Eurasian plate; and the Amundsen Basin and Nansen Basin AUs which encompass the abyssal plains north and south of the Gakkel Ridge spreading centre, respectively. The primary petroleum system thought to be present is sourced in c . 50–44 Ma (Early to Middle Eocene) condensed pelagic deposits that could be widespread in the province. Mean estimates of undiscovered, technically recoverable petroleum resources include <1 billion barrels of oil (BBO) and about 1.4 trillion cubic feet (TCF) of nonassociated gas in Lena Prodelta AU, and <0.4 BBO and 3.4 TCF nonassociated gas in the Nansen Basin Margin AU. The Nansen Basin and Amundsen Basin AUs were not quantitatively assessed because they have less than 10% probability of containing at least one accumulation of 50 MMBOE (million barrels of oil equivalent).

Specific Character of Magnetic Field and Development of Oceanic Ridges in Arctic Ocean Basin: Summary Available to Purchase
Abstract The Eurasian basin, which includes the mid-ocean Gakkel Ridge and the abyssal Nansen and Amundsen basins, is the only region of the world's oceans where the magnetic field has been thoroughly studied. Systematic surveys have also been made over the Lomonosov and Mendeleyev Ridges and in intervening basins adjacent to the Eurasian coast of the Arctic Ocean. Being so well surveyed, the Arctic basin is particularly useful for studying the relation of magnetic anomalies to complex oceanic regions.
