The Dissolved Organic Carbon Controversy:An Update
Dissolved Organic Carbon Controversy An Update
2015/8/19
This note is intended as an update on activities to improve the measurement of dissolved organic carbon (DOC) in seawater. The exciting and controversial paper by Sugimura and Suzuki (1988) led to ren...
Carbon isotopes in the ocean model of the Community Earth System Model (CESM1)

2015/8/11
Carbon isotopes in the ocean are frequently used
as paleoclimate proxies and as present-day geochemical
ocean tracers. In order to allow a more direct comparison of
climate model results with this ...
Following the highly publicized 1998 E1 Niño event, interest in how climatic events in the tropics affects global climate has grown. However, an understanding of the long-term natural variability...
It is a great pleasure to give this, the first Revelle Commemorative Lecture, for [ had the privilege both to know Roger over the last decade of his career, and to work on problems in whicln he was ke...
Radiocarbon in Corals: Records of the Carbon Cycle, Surface Circulation and Climate
Carbon Cycle Surface Circulation
2015/7/31
For more than two decades, coral skeletons have been used to reconstruct records of isotopic and chemical ratios in surface seawater (for reviews, see Druffel, 1997a; Gagan et al., 2000). Here I demon...

2015/7/20
Anthropogenically driven climate change will rapidly become Earth's dominant transformative influence in the coming decades. The oceanic biological pump—the complex suite of processes that results in ...
Was the Late Paleocene-Early Eocene Hot Because Earth Was Flat? An Ocean Lithium Isotope View of Mountain Building,Continental Weathering, Carbon Dioxide,and Earth's Cenozoic Climate
Late Paleocene-Early Eocene Hot Earth Was Flat Ocean Lithium Isotope View Mountain Building Continental Weathering Carbon Dioxide Earth's Cenozoic Climate
2015/7/17
Hothouse climates in Earth's geologic past, such as the Eocene epoch, are thought to have been caused by the release of large amounts of carbon dioxide and/or methane, which had been stored as carbon ...
Scientific Outcomes and Future Challenges of the Ocean Carbon and Biogeochemistry Program
Scientific Outcomes Future Challenges Ocean Carbon Biogeochemistry Program
2015/7/17
The ocean plays a major role in shaping Earth's climate, regulating levels of key atmospheric trace gases such as carbon dioxide on time scales of decades to millennia. Much progress has been made in ...
Integrated Carbon Budget Models for the Everglades Terrestrial-Coastal-Oceanic Gradient: Current Status and Needs for Inter-Site Comparisons
Terrestrial-Coastal-Oceanic Gradient Inter-Site Comparisons
2015/7/16
Recent studies suggest that coastal ecosystems can bury significantly more C than tropical forests, indicating that continued coastal development and exposure to sea level rise and storms will have gl...
Simultaneous measurement of the gross and net primary production of the benthic community and the net input of organic carbon delivered by currents to the coral reef flat of the north shore of Moorea,...
