Journal ArticleDOI
Biogeochemistry of carbon in the Amazon River
Jeffrey E. Richey,John I. Hedges,Allan H. Devol,Paul D. Quay,Reynaldo Luiz Victoria,Luiz Antonio Martinelli,Bruce R. Forsberg +6 more
TL;DR: The average export of total organic carbon (TOC) was 36.1 Tg yr-i (8.5 g m-2 yr-I), of which 62% was DOC, 34% was FPOC, and 4% was CPOC.
Journal ArticleDOI
Specific inhibition of nitrite oxidation by chlorate and its use in assessing nitrification in soils and sediments.
L. W. Belser,E. L. Mays +1 more
TL;DR: It was concluded that chlorate had relatively little inhibitory effect on ammonium oxidation, however, under some conditions chlorate was not completely effective in blocking nitrite oxidation, and the causes of this were investigated.
Journal ArticleDOI
Consistent fractionation of 13C in nature and in the laboratory: growth-rate effects in some haptophyte algae.
Robert R. Bidigare,Arnim Fluegge,Arnim Fluegge,Katherine H. Freeman,Kristi L. Hanson,John M. Hayes,John M. Hayes,David J. Hollander,David J. Hollander,John P. Jasper,Linda L. King,Edward A. Laws,Jeffrey C. Milder,Frank J. Millero,Richard D. Pancost,Brian N. Popp,Paul A. Steinberg,Stuart G. Wakeham +17 more
TL;DR: Before concentrations of dissolved CO2 can be estimated from isotopic fractionations, some means of accounting for variations in growth rate must be found, perhaps by drawing on relationships between [PO4] and Cd/Ca ratios in shells of planktonic foraminifera.
Journal ArticleDOI
Spatial and temporal distributions of prochlorophyte picoplankton in the North Atlantic Ocean
Robert J. Olson,Sallie W. Chisholm,Erik R. Zettler,Mark A. Altabet,J.A. Dusenberry,J.A. Dusenberry +5 more
TL;DR: In the Sargasso Sea in May 1988 and May 1989 prochlorophytes were present throughout the upper water column, and they observed the highest concentrations in surface waters within the Gulf Stream as discussed by the authors.
Journal ArticleDOI
The role of particulate carbohydrate exudates in the flocculation of diatom blooms
TL;DR: The findings indicate that TEP should be included in models of particle aggregation in the ocean, as the abundance, large size and high sticking coefficient of TEP make them essential to the aggregation of diatom blooms.
