Journal ArticleDOI
Determination of carbonate and organic matter in calcareous sediments and sedimentary rocks by loss on ignition; comparison with other methods
TL;DR: In this article, a modified ignition loss method is described for determining organic and carbonate carbon in calcareous sedimentary materials using equipment found in most laboratories and has been found to equal or excel the accuracy and precision of other methods tested and has the advantage of being considerably faster if large numbers of samples are to be analyzed.
Journal ArticleDOI
Geochemical and climatic effects of increased marine organic carbon burial at the Cenomanian/Turonian boundary
TL;DR: In this paper, the authors present new data from nine localities and demonstrate that a positive excursion in the carbon isotope composition of organic carbon at or near the C/T boundary is nearly synchronous with that for carbonate and is widespread throughout the Tethys and Atlantic basins.
Journal ArticleDOI
Magnitude and significance of carbon burial in lakes, reservoirs, and peatlands
Walter E. Dean,Eville Gorham +1 more
TL;DR: In this article, the authors estimate that lakes are currently accumulating organic carbon (OC) at an estimated annual rate of about 42 Tg�yr −1, and most of the OC in all but the most oligotrophic of these lakes is autochthonous, produced by primary production in the lakes.
Journal ArticleDOI
Geochemical evidence for suppression of pelagic marine productivity at the Cretaceous/Tertiary boundary
TL;DR: In this article, stable isotope data from planktonic and benthic micro-fossils across the Cretaceous/Tertiary boundary in the North pacific was used to reveal a rapid and complete breakdown in this biologically mediated gradient.
Journal ArticleDOI
Inorganic geochemical indicators of glacial-interglacial changes in productivity and anoxia on the California continental margin
TL;DR: In this article, the authors show that organic productivity under the California Current upwelling system was highest during OIS-3 and the Holocene, and lowest during the last glacial interval (LGI, ca. 24-10 ka).
