Available in PDF, EPUB and Kindle. Book excerpt: The details of planktonic and benthonic Foraminifera distribution in nine representative cores has been selected as a method to illustrate Arctic Ocean Late Cenozoic faunal patterns. The cores selected represent some of the most complete and unambiguous cores in terms of magnetic stratigraphy and fauna. The results are representative of actual patterns seen in many other cores. Taken together, the data on planktonic and benthonic Foraminifera give some idea of the Foraminiferal assemblages during much of the Pliocene and Pleistocene in the Arctic Ocean. The cores have been obtained from operations on ice-island T-3, since 1963.

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).

This book was released on 2015-10-02 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of fossil planktonic foraminifera as markers for biostratigraphical zonation and correlation underpins most drilling of marine sedimentary sequences and is key to hydrocarbon exploration. The first - and only - book to synthesise the whole biostratigraphic and geological usefulness of planktonic foraminifera, Biostratigraphic and Geological Significance of Planktonic Foraminifera unifies existing biostratigraphic schemes and provides an improved correlation reflecting regional biogeographies.Renowned micropaleontologist Marcelle K. Boudagher-Fadel presents a comprehensive analysis of existing data on fossil planktonic foraminifera genera and their phylogenetic evolution in time and space. This important text, now in its Second Edition, is in considerable demand and is now being republished by UCL Press.

Download or read book Benthic Foraminifera as Paleo sea ice Indicators in the Western Arctic Ocean written by Kelly Best Lazar and published by . This book was released on 2014 with total page pages. 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).
