This book was released on 1973 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Foraminifera populations and distributions of five deep sea sediment cores recovered from the Arctic Ocean yielded data on 126 species of Foraminifera. Abundance data and species appearance and mortality data across geomagnetic reversal intervals in the cores show no positive correlation. Arctic Ocean Foraminifera apparently do not respond in any significant way to magnetic reversals of the earth's magnetic field. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: Although it is generally accepted that the Arctic Ocean is a very sensitive and important region for changes in the global climate, this region is the last major physiographic province of the earth whose short-and long-term geological history is much less known in comparison to other ocean regions. This lack of knowledge is mainly caused by the major technological/logistic problems in reaching this harsh, ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. During the the last about 20 years, however, several international and multidisciplinary ship expeditions, including the first scientific drilling on Lomonosov Ridge in 2004, a break-through in Arctic research, were carried out into the central Artic and its surrounding shelf seas. Results from these expeditions have greatly advanced our knowledge on Arctic Ocean paleoenvironments. Published syntheses about the knowledge on Arctic Ocean geology, on the other hand, are based on data available prior to 1990. A comprehensive compilation of data on Arctic Ocean paleoenvironment and its short-and long-term variability based on the huge amount of new data including the ACEX drilling data, has not been available yet. With this book, presenting (1) detailed information on glacio-marine sedimentary processes and geological proxies used for paleoenvironmental reconstructions, and (2) detailed geological data on modern environments, Quaternary variability on different time scales as well as the long-term climate history during Mesozoic-Tertiary times, this gap in knowledge will be filled.*Aimed at specialists and graduates *Presents background research, recent developments, and future trends*Written by a leading scholar and industry expert

Available in PDF, EPUB and Kindle. Book excerpt: As global climate continues to warm, the Arctic Ocean is becoming increasingly vulnerable, largely due to a fast retreat of sea ice. Knowledge of paleo-sea-ice conditions is essential for comprehending the changing Arctic system. This study combines micropaleontological (foraminiferal) data with existing litho- and chronostratigraphic results to construct a more resolved stratigraphic record and history of sea-ice change during the Quaternary in the western Arctic Ocean. Benthic foraminiferal assemblages were investigated in four sediment cores from the Northwind, Mendeleev, and Lomonosov Ridges (western Arctic Ocean). A uniquely-preserved sediment core from the Northwind Ridge was found to contain the longest calcareous foraminiferal record in the Arctic Ocean, estimated to extend to the early Pleistocene, ca. 1.5 Ma. This record was divided into two assemblage zones, representing distinct changes in foraminiferal composition with respect to ecological groups (polar vs. phytodetrital species) and extinct taxa. The distribution of polar and phytodetrital species yields significant information related to sea ice (perennial vs. seasonal) and associated climatic conditions. A principal faunal and sedimentary turnover occurred near the early-middle Pleistocene boundary (estimated ca 0.7-0.8 Ma), indicating an advance of perennial sea ice along with an increase in glacial inputs from the Laurentide ice sheet at the end of the Mid-Pleistocene Transition (MPT).
