Journal ArticleDOI
A Time-Series View of Changing Ocean Chemistry Due to Ocean Uptake of Anthropogenic CO2 and Ocean Acidification
Nicholas R. Bates,Yrene Astor,Matthew J. Church,Kim I. Currie,John E. Dore,Melchor González-Dávila,Laura Lorenzoni,Frank E. Muller-Karger,Jón Ólafsson,J. Magdalena Santana-Casiano +9 more
TL;DR: In this article, the long-term changes in dissolved inorganic carbon (DIC), salinity-normalized DIC, and surface seawater pCO2 (partial pressure of CO2) due to the uptake of anthropogenic CO2 and its impact on the ocean's buffering capacity are discussed.
Journal ArticleDOI
Annual cycle of primary production in the Cariaco Basin: Response to upwelling and implications for vertical export
Frank E. Muller-Karger,Ramon Varela,Robert C. Thunell,Mary I. Scranton,Richard Bohrer,Gordon T. Taylor,Juan Capelo,Yrene Astor,Eric Tappa,Tung-Yuan Ho,John J. Walsh +10 more
TL;DR: The upwelling cycle of Subtropical Underwater (SUW) started around October and lasted through approximately May of the following year in the Cariaco Basin, off Venezuela as discussed by the authors.
Journal ArticleDOI
Comparison of Vertical Distributions of Prokaryotic Assemblages in the Anoxic Cariaco Basin and Black Sea by Use of Fluorescence In Situ Hybridization
Xueju Lin,Stuart G. Wakeham,Isabell F. Putnam,Yrene Astor,Mary I. Scranton,Andrei Y. Chistoserdov,Gordon T. Taylor +6 more
TL;DR: For both basins, significant differences in total prokaryotic abundance and phylogenetic composition were observed among oxic, anoxic, and transitional (redoxcline) waters.
Journal ArticleDOI
Nitrogen Isotope Dynamics of the Cariaco Basin, Venezuela
TL;DR: The 15N/14N measurements of water column nitrate and ammonium, sinking particles, and sediments from the Cariaco Basin, an anoxic marine basin off the coast of Venezuela, were reported in this paper.
Journal ArticleDOI
Seasonal and Interannual Variation in the Hydrography of the Cariaco Basin: Implications for Basin Ventilation
TL;DR: The hydrography of the Cariaco Basin (temperature, salinity, density, dissolved oxygen concentration) was studied using monthly observations collected between November 1995 and August 1998 at the CArbon Retention In A Colored Ocean (CARIACO) time series station (10.51N, 64.661W) as mentioned in this paper.
