TLDR
The effects of the Cenomanian-Turonian Oceanic Anoxic Event (OAE) in the Chalk Sea of NW Europe have been investigated using published macrofossil records combined with new detailed sedimentological, foraminiferal, ostracod, calcareous nannofossil, dinoflagellate cyst and stable-isotope data from Dover, England as mentioned in this paper.About:

Oceanic anoxic events and plankton evolution: Biotic response to tectonic forcing during the mid-Cretaceous
TL;DR: In this paper, the authors investigated the link between submarine volcanism, plankton evolution, and the cycling of carbon through the marine biosphere, and concluded that there were important linkages between submarine volcano activity and marine productivity.
Journal ArticleDOI
Carbon- and oxygen-isotope stratigraphy of the English Chalk and Italian Scaglia and its palaeoclimatic significance
TL;DR: A detailed carbon and oxygen-isotope stratigraphy has been generated from Upper Cretaceous coastal Chalk sections in southern England (East Kent; Culver Cliff, Isle of Wight; Eastbourne and Seaford Head, Sussex; Norfolk Coast) and the British Geological Survey (BGS) Trunch borehole, Norfolk as discussed by the authors.

Secular variation in Late Cretaceous carbon isotopes: a new δ13C carbonate reference curve for the Cenomanian-Campanian (99.6-70.6 Ma)
TL;DR: In this article, carbon stable isotope variation through the Cenomanian-Santonian stages is characterized using data for 1769 bulk pelagic carbonate samples collected from seven Chalk successions in England.
Journal ArticleDOI
Calcareous nannofossils and Mesozoic oceanic anoxic events
TL;DR: The Toarcian, Early Aptian and latest Cenomanian OAEs are truly global in nature, commonly carbonate-poor, and typically represented by organic carbon-rich black shales.
Journal ArticleDOI
Evidence for rapid climate change in the Mesozoic-Palaeogene greenhouse world
TL;DR: In both the early Toarcian and early Aptian cases, the negative carbon–isotope excursion precedes global excess carbon burial across a range of marine environments, a phenomenon that defines these intervals as oceanic anoxic events (OAEs).

Chronology of fluctuating sea levels since the triassic.
TL;DR: An effort has been made to develop a realistic and accurate time scale and widely applicablechronostratigraphy and to integrate depositional sequences documented in public domain outcrop sections from various basins with this chronostratigraphic framework.
Journal ArticleDOI
Isotopic standards for carbon and oxygen and correction factors for mass-spectrometric analysis of carbon dioxide
TL;DR: In this paper, Niee's and Solenhofen standards were compared to the Chicago PDB standard for carbon and oxygen isotope ratios, and the correction factors for instrumental effects and for the nature of the mass spectra were derived.
Journal ArticleDOI
On the Isotopic Chemistry of Carbonates and a Paleotemperature Scale
TL;DR: In this paper, the temperature variation of the fractionation of oxygen in exchange reactions between dissolved carbonate and water and between calcite and water was calculated on theoretical grounds, and checked experimentally.

Cretaceous oceanic anoxic events: causes and consequences
TL;DR: In this article, an interpretation of these events as the result of the interplay of two major geologic and climatic factors is given, namely, the Late Cretaceous transgression which increased the area and volume of shallow epicontinental and marginal seas and was accompanied by an increase in the production of organic carbon; and the existence of an equable global climate which reduced the supply of cold oxygenated bottom water to the world ocean.

Isotopic evidence for source of diagenetic carbonates formed during burial of organic-rich sediments
TL;DR: In this article, the relative dominance of different burial diagenesis processes within specific depth intervals is given by the isotopic composition of incorporated oxygen which is temperature dependent (1) 0 to −2‰, (2) −1.5 to −5'
