Journal ArticleDOI

James C. Orr,Victoria J. Fabry,Olivier Aumont,Laurent Bopp,Scott C. Doney,Richard A. Feely,Anand Gnanadesikan,Nicolas Gruber,Akio Ishida,Fortunat Joos,Robert M. Key,Keith Lindsay,Ernst Maier-Reimer,Richard J. Matear,Patrick Monfray,Anne Mouchet,Raymond G. Najjar,Gian-Kasper Plattner,Keith B. Rodgers,Christopher L. Sabine,Jorge L.

TL;DR: 13 models of the ocean–carbon cycle are used to assess calcium carbonate saturation under the IS92a ‘business-as-usual’ scenario for future emissions of anthropogenic carbon dioxide and indicate that conditions detrimental to high-latitude ecosystems could develop within decades, not centuries as suggested previously.
Journal ArticleDOI
Potential climate-change impacts on the Chesapeake Bay
Raymond G. Najjar,Christopher R. Pyke,Mary Beth Adams,Denise L. Breitburg,Carl Hershner,Michael Kemp,Robert W. Howarth,Margaret R. Mulholland,Michael Paolisso,David H. Secor,Kevin G. Sellner,Denice H. Wardrop,Robert Wood +12 more
TL;DR: In this article, the potential impact of climate change on the Chesapeake Bay watershed is reviewed. And the authors suggest that the magnitude of these changes is sensitive to the CO 2 emission trajectory, so that actions taken now to reduce CO2 emissions will reduce climate impacts on the Bay.
Journal ArticleDOI
Evaluation of ocean carbon cycle models with data-based metrics
Katsumi Matsumoto,Jorge L. Sarmiento,Robert M. Key,Olivier Aumont,John L. Bullister,Ken Caldeira,J.-M. Campin,Scott C. Doney,Helge Drange,Jean-Claude Dutay,Michael J. Follows,Yongqi Gao,Anand Gnanadesikan,Nicolas Gruber,Akio Ishida,Fortunat Joos,Keith Lindsay,Ernst Maier-Reimer,John Marshall,Richard J. Matear,Patrick Monfray,Anne Mouchet,Raymond G. Najjar,Gian-Kasper Plattner,Reiner Schlitzer,Richard D. Slater,P. S. Swathi,I. Totterdell,Marie-France Weirig,Yasuhiro Yamanaka,Andrew Yool,James C. Orr +31 more
TL;DR: In this paper, the authors used radiocarbon and chlorofluorocarbon-11 data from the World Ocean Circulation Experiment (WOCE) to assess a suite of 19 ocean carbon cycle models.
Journal ArticleDOI
Downward transport and fate of organic matter in the ocean: Simulations with a general circulation model.
TL;DR: A phosphorus-based model of nutrient cycling has been developed and used in conjunction with a general circulation model to evaluate the roles of the dissolved and sinking particulate phases in the downward transport of organic matter in the ocean.
Journal ArticleDOI
A new coupled, one-dimensional biological-physical model for the upper ocean: Applications to the JGOFS Bermuda Atlantic Time-series Study (BATS) site
TL;DR: In this paper, a coupled, one dimensional biological-physical model applied to the subtropical region near Bermuda is presented, which includes the effects of photoadaptation, phytoplankton aggregation, and particle remineralization in the aphotic zone.
