The performance of 36 models (22 ocean color models and 14 biogeochemical ocean circulation models (BOGCMs)) that estimate depth‐integrated marine net primary productivity (NPP) was assessed by comparing their output to in situ 14C data at the Bermuda Atlantic Time series Study (BATS) and the Hawaii Ocean Time series (HOT) over nearly two decades. Specifically, skill w...... hiện toàn bộ
The CAFE model: A net production model for global ocean phytoplankton
Global Biogeochemical Cycles - Tập 30 Số 12 - Trang 1756-1777 - 2016
Greg M. Silsbe, Michael J. Behrenfeld, Kimberly H. Halsey, Allen J. Milligan, Toby K. Westberry
AbstractThe Carbon, Absorption, and Fluorescence Euphotic‐resolving (CAFE) net primary production model is an adaptable framework for advancing global ocean productivity assessments by exploiting state‐of‐the‐art satellite ocean color analyses and addressing key physiological and ecological attributes of phytoplankton. Here we present the first implementation of th...... hiện toàn bộ
A global ocean carbon climatology: Results from Global Data Analysis Project (GLODAP)
Global Biogeochemical Cycles - Tập 18 Số 4 - 2004
Robert M. Key, Alex Kozyr, C. Sabine, Kitack Lee, Rik Wanninkhof, John L. Bullister, Richard A. Feely, Frank J. Millero, Calvin W. Mordy, Tianji Peng
During the 1990s, ocean sampling expeditions were carried out as part of the World Ocean Circulation Experiment (WOCE), the Joint Global Ocean Flux Study (JGOFS), and the Ocean Atmosphere Carbon Exchange Study (OACES). Subsequently, a group of U.S. scientists synthesized the data into easily usable and readily available products. This collaboration is known as the Global Ocean Data Analysi...... hiện toàn bộ
Coupled nitrogen and oxygen isotope measurements of nitrate along the eastern North Pacific margin
Global Biogeochemical Cycles - Tập 19 Số 4 - 2005
Daniel M. Sigman, Julie Granger, Peter J. DiFiore, Moritz F. Lehmann, Ruby Ho, Greg Cane, Alexander van Geen
Water column depth profiles along the North Pacific margin from Point Conception to the tip of Baja California indicate elevation of nitrate (NO3−) 15N/14N and 18O/16O associated with denitrification in the oxygen‐deficient thermocline waters of the eastern tropical...... hiện toàn bộ
Mercury isotopes in a forested ecosystem: Implications for air‐surface exchange dynamics and the global mercury cycle
Global Biogeochemical Cycles - Tập 27 Số 1 - Trang 222-238 - 2013
Jason D. Demers, Joel D. Blum, Donald R. Zak
Forests mediate the biogeochemical cycling of mercury (Hg) between the atmosphere and terrestrial ecosystems; however, there remain many gaps in our understanding of these processes. Our objectives in this study were to characterize Hg isotopic composition within forests, and use natural abundance stable Hg isotopes to track sources and reveal mechanisms underlying the cycling of Hg. We qu...... hiện toàn bộ
The contribution of ocean‐leaving DMS to the global atmospheric burdens of DMS, MSA, SO2, and NSS SO4=
Global Biogeochemical Cycles - Tập 17 Số 2 - 2003
Mtinkheni Gondwe, Maarten Krol, W. W. C. Gieskes, Wim Klaassen, Hein de Baar
The contribution of ocean‐derived DMS to the atmospheric burdens of a variety of sulphur compounds (DMS, MSA, SO2, and nss SO4=) is quantified from season to season. Such quantification, especially for nss SO4= (the climate‐relevant product of DMS oxidation), is essential for the quanti...... hiện toàn bộ
Amazonian biomass burning‐derived acid and nutrient deposition in the north Andean montane forest of Ecuador
Global Biogeochemical Cycles - Tập 22 Số 4 - 2008
Jens Boy, Rütger Rollenbeck, Carlos Valarezo, Wolfgang Wilcke
We explored the influence of biomass burning in Amazonia and northeastern Latin America on N, C, P, S, K, Ca, Mg, Al, Mn, and Zn cycles of an Andean montane forest in south Ecuador exposed to the Amazon basin between May 1998 and April 2003. We assessed the response of the element budget of three microcatchments (8–13 ha) to the variations in atmospheric deposition between the intensive bu...... hiện toàn bộ
Air‐borne dust fluxes to a deep water sediment trap in the Sargasso Sea
Global Biogeochemical Cycles - Tập 12 Số 2 - Trang 311-320 - 1998
T. D. Jickells, Stephen Dorling, W. G. Deuser, Thomas M. Church, R. Arimoto, Joseph M. Prospero
The record of atmospheric dust deposition as recorded by a deep sea sediment trap in the Sargasso Sea is presented. The record is shown to be consistent with the limited available data on directly measured atmospheric dust loadings. The seasonality of the sediment trap dust flux is different from that of the atmospheric deposition as a result of seasonal biological cycles in the surface wa...... hiện toàn bộ
Biomass burning in Asia: Annual and seasonal estimates and atmospheric emissions
Global Biogeochemical Cycles - Tập 17 Số 4 - 2003
David G. Streets, K. F. Yarber, Jung‐Hun Woo, Gregory R. Carmichael
Estimates of biomass burning in Asia are developed to facilitate the modeling of Asian and global air quality. A survey of national, regional, and international publications on biomass burning is conducted to yield consensus estimates of “typical” (i.e., non‐year‐specific) estimates of open burning (excluding biofuels). We conclude that 730 Tg of biomass are burned in a typical year from b...... hiện toàn bộ
