      The Cenozoic planktonic foraminifera (PF) (calcareous zooplankton) have arguably the most detailed fossil record of any group. The quality of this record allows models of environmental controls on macroecology, developed for Recent assemblages, to be tested on intervals with profoundly different climatic by:   Ocean history is largely read from deep-sea sediments, using microscopic fossils, notably foraminifers. Ice age fluctuations in the ocean's sediments provided for a new geologic understanding of climate change. The discovery of rapid decay of ice masses at the end of glacial periods was especially important, yielding rates of sea level rise reaching values of 1 to 2 m .

    The Cenozoic planktonic foraminifera (PF) (calcareous zooplankton) have arguably the most detailed fossil record of any group. The quality of this record allows models of environmental controls on macroecology, developed for Recent assemblages, to be tested on intervals with profoundly different climatic by: The deep-sea floor (bathyal and abyssal depths, i.e., depths > m) constitutes the largest habitat on Earth (e.g., Norse, ; Verity et al., ).The deep-ocean floor had long been thought to be devoid of life (Wyville Thomson, ), but in the early s the Antarctic expedition of James Clarke Ross on the Erebus found indications that life existed there.

    several decades worth of scientific drilling in the sea and on land have provided many answers and questions. Peter Barker (British Antarctic Survey) presented the Cenozoic context to SO development, with several aspects of Antarctic glaciation that are well-known: (1) Significant glaciation started ~34 Ma, and cooling intensified from 16 to 13 Ma. The Asahiko Taira International Scientific Ocean Drilling Research Prize (The Taira Prize) is given annually to one honoree in recognition of “outstanding transdisciplinary research accomplishment in ocean drilling.” Established in , the Taira Prize is a partnership between the American Geophysical Union (AGU) and the Japan Geoscience.

In this book, we will examine, on a global scale, the groups of freshwater fishes that have a fossil record dating from the Mesozoic and Cenozoic eras, a period covering the last million years of the Earth’s history. We will focus on the paleogeographical and paleoenvironmental contexts that surround the fossils and attempt to situate.

The proxy of oxygen isotopic composition (δ 18 O) obtained from benthic foraminiferal shells found in marine sediment cores [Zachos et al., a] indicates changes in global ice volume (from around 34 Ma) and bottom water temperature, heavier δ 18 O values reflecting more ice/lower temperatures.

Scientific ocean drilling played a significant role in producing the long time series of marine oxygen isotope variability that was used to modify and constrain the paleomagnetic reversal ages and to develop a revised Astronomical Polarity Time Scale for the Cenozoic (Kent, ), thus linking continental- and marine-based research on a common.

Evidence of Recent Climate Change. While climate has changed many times in the past (see chapter and chapter ), the scientific consensus is that human activity is causing climate to change today more this seems like a new idea, it has been suggested for more than 75 section describes the evidence that scientists agree is most likely a result.

For more than 30 years, following the abandonment of the bungled Mohole project, designed to drill a hole through the crust-mantle boundary, the National Science Foundation (NSF) has energetically supported and shepherded along a spectacularly successful scientific ocean drilling program that has cored oceanic sediments and crust at more than a thousand places over.

Land plants began to flourish and diversify during Silurian time. Plants on land became a food source allowing the first animals to emerge onto dry land (including insects and scorpions)(Figure ). The Geological Society has prepared a position statement on climate change, focusing specifically on the geological evidence.

Scientists in the Soviet Union appear to have used the term "anthropocene" as early as the s to refer to the Quaternary, the most recent geological period.

Ecologist Eugene F. Stoermer subsequently used "anthropocene". Marine mammals are aquatic mammals that rely on the ocean and other marine ecosystems for their existence. They include animals such as seals, whales, manatees, sea otters and polar are an informal group, unified only by their reliance on marine environments for feeding.
