Evolution of the Miocene ocean in the eastern North Pacific as inferred from oxygen and carbon isotopic ratios of foraminifera Author(s) Miocene ocean book Barrera. Buy The Miocene Ocean: Paleoceanography and Biogeography: NHBS - Edited By: JP Kennett, Geological Society of America.

Oxygen and carbon isotopic ratios of planktonic and benthonic foraminifera have provided information about the evolution of the oceans at low- and mid-latitude sites in the Miocene eastern North Pacific Ocean. DSDP Site (12° N; 91° W) provides a record of early and middle Miocene Miocene ocean book conditions in the eastern Miocene ocean book Pacific.

This volume brings together research carried out within the Cenozoic Paleoceanography Project (CENOP), a goal of which was to generate paleoceanographic reconstructions of the Miocene Cited by: 1.

This book constitutes an excellent and probably unique example of how interdisciplinary stratigraphic and geochronologic studies are approached with modern methodologies and techniques.

It contains numerous unpublished, accurate radioisotopic dates of volcano-sedimentary layers interbedded in fossiliferous marine and continental Miocene sequences representing Mediterranean and Pacific Book Edition: 1. On the basis of stable isotope and quantitative micropaleontological studies, the authors have related these data bases to parameters and processes of the Miocene ocean book Ocean, including paleogeography, Miocene ocean book, circulation, water mass distributions, temperature variability, Miocene ocean book water mass structure, biogeography, and biotic these authors attained their goal is attested to by the quality Cited by: 1.

Although it was in paperback (when one expects sometimes poor editing), I don't recall any real problems.

The series caught my attention, first for its concept of a computer with human components ("Souls in the Great Machine") and then for the plots as they developed over the next two books, "The Miocene Arrow" being the second/5(28). In the middle to late Miocene such carbonate crash events were a widespread phenomenon throughout the world's ocean basins.

However, low carbonate contents may also derive from terrigenous dilution and carbonate production changes in surface waters as shown for late Miocene records of the South Atlantic (Diester-Haass et al.,Westerhold Cited by: 3.

The Tethys Sea connection between the Mediterranean and Indian Ocean was severed in the Mid-Miocene causing the increase in aridity in Southern Europe.

The Paratethys barrier, which isolated Western Europe from the exchange of flora and fauna, was periodically disrupted, allowing for the migration of animals. Miocene tectonics and paleoclimate Miocene ocean current circulation The Miocene saw a change in global circulation patterns due to slight position changes of the continents and globally warmer climates.

Conditions on each continent changed somewhat because of these positional changes, however it was an overall increase in aridity through moun. The late Miocene evolution of the deep ocean circulation is associated with major climate changes, like the beginning of the glaciation of Southern Greenland, and with a perturbation of the carbon cycle (the so‐called late Miocene carbon isotope shift [e.g., Billups, ; Bickert et al., ]).

We examine the role of the vegetation cover and the associated hydrological cycle on the deep ocean circulation during the Late Miocene (~10 million years ago). In our simulations, an open Central American gateway and exchange with fresh Pacific waters leads to a weak and shallow thermohaline circulation in the North Atlantic Ocean which is consistent with most other modeling studies for this Cited by: The clay fraction of sediments drilled at Ocean Drilling Program (ODP) sites and is composed of variable proportions of chlorite, illite, smectite, kaolinite, vermiculite and mixed-layers such as illite/vermiculite (I/V) and chlorite/vermiculite (C/V).

Written by a foremost authority in the field. The Miocene is the first epoch of the Neogene period of the Cainozoic. It started about 23 million years ago and ended about million years ago. The rock beds that mark the start and end are well known, but the exact dates of the start and end of the period are uncertain.

The biota becomes 'modern'. The Miocene was named by Sir Charles g: ocean book. The mid Miocene, including the mid Miocene climate transition (MMCT) at ~ Ma 1, represents one of the three most significant cooling episodes of the Cenozoic 2,3, along with the Eocene-Oligocene transition 4 (~34 Ma) and onset of Northern Hemisphere Glaciation (~ Ma).

Yet in contrast to these events, comparatively little is known about the causes and feedbacks of this mid Miocene by: 8. Miocene epoch mī´əsēn [], fourth epoch of the Tertiary period in the Cenozoic era of geologic time (see Geologic Timescale, table), lasting from around to million years ago.

North America was more extensively submerged in the Miocene than in the preceding Oligocene epoch and underwent considerable crustal disturbances. The Atlantic and Gulf coasts were flooded about as.

The Eocene-Oligocene and the Mid-Miocene climate transitions are two major cooling steps in the Cenozoic climate evolution (Zachos et al.,[]) from greenhouse to “icehouse” climate circulation changes and atmospheric pCO 2 variations are often cited as potential catalysts of these cooling events (DeConto and Pollard,[]).Cited by: Miocene Epoch.

Notable in the development of primates and human evolution, are fossilized remains of Ardipithecus ramidus, perhaps one of the earliest identifiable ancestors of ized remains found in Ethiopia date to approximately six million years ago, near the end of the Miocene Epoch.

Importantly, the fossilized bones found provide evidence that Ardipithecus ramidus could walk upright. During the Miocene, thornscrub may well have been the regional vegetation in drier areas to the north that are now Sonoran Desert.

Thornscrub, in fact, may be the ancestral biome of many Sonoran Desert plants and animals. The Sonoran Desert itself came about during a drying trend in the middle Miocene.

At 16 Ma, theasymmetric distribution of temperatures in the South Pacific Ocean remained, and thelatitudinal temperature gradient, inferred from the isotopic data, was gentler than that ofeither the late Miocene or Modern n the late early Miocene and late Miocene, surface waters at most lowlatitudePacific sites warmed while those at Cited by:.
