International Carbon Coordination: Roger Revelle's Legacy in the Intergovernmental Oceanographic Commission
International Carbon Coordination intergovernmental Oceanographic Commission
<
2015/7/8
Since its inception in 1960, the Intergovernmental Oceanographic Commission (IOC) has been responsible for organizing and coordinating the scientific investigation of ocean carbon. Roger Revelle (Scri...
BOOK REVIEW | Chemical Oceanography and the Marine Carbon Cycle
Chemical Oceanography Marine Carbon Cycle
<
2015/7/3
Chemical Oceanography and the Marine Carbon Cycle reflects the two authors' wealth of research and teaching experience, and the community is fortunate that Steve Emerson was able to complete this majo...
Autonomous Observations of the Ocean Biological Carbon Pump
Autonomous Observations Ocean Biological Carbon Pump
<
2015/7/3
Prediction of the substantial biologically mediated carbon flows in a rapidly changing and acidifying ocean requires model simulations informed by observations of key carbon cycle processes on the app...
Humans concerned about climate change are working to find ways of capturing excess carbon dioxide (CO2) from the atmosphere and sequestering it in the Earth. But Nature has its own methods for the rem...
Regional-scale variation of dissolved organic carbon concentrations in Swedish lakes
Organic carbon lakes
<
2014/10/16
We assessed spatial variability in dissolved organic carbon (DOC) concentrations measured in nearly 2000
Swedish lakes. Inter-lake variance peaked at two different scales, representing within-region ...
Identifying variable sea ice carbon contributions to the Arctic ecosystem: A case study using highly branched isoprenoid lipid biomarkers in Cumberland Sound ringed seals
Sea ice carbon The arctic ecosystem
<
2014/10/16
We analyzed liver samples from 322 ringed seals (Pusa hispida) collected from Cumberland Sound (southeast
Baffin Island) to test our ability to differentiate between carbon sources in near apex preda...
Microscopic organism plays a big role in ocean carbon cycling, Scripps scientists discover
Microscopic organism big role ocean carbon cycling Scripps scientists discover
<
2014/5/13
It’s broadly understood that the world’s oceans play a crucial role in the global-scale cycling and exchange of carbon between Earth’s ecosystems and atmosphere. Now scientists at Scripps Institution ...
Transformation and fate of microphytobenthos carbon in subtropical shallow subtidal sands: A 13C-labeling study
Transformation fate of microphytobenthos carbon subtropical shallow subtidal sands A 13C-labeling study
<
2014/4/2
Microphytobenthos (MPB) in photic sediments are highly productive but the fate of this production remains uncertain. Over 33 d, tracing of 13C from added bicarbonate in subtropical shallow subtidal sa...
The marine inorganic carbon system along the Gulf of Mexico and Atlantic coasts of the United States: Insights from a transregional coastal carbon study
The marine inorganic carbon system along Gulf of Mexico Atlantic coasts the United States a transregional coastal carbon study
<
2014/4/2
Distributions of total alkalinity (TA), dissolved inorganic carbon (DIC), and other parameters relevant to the marine inorganic carbon system were investigated in shelf and adjacent ocean waters durin...
Phosphorus enrichment and carbon depletion contribute to high Microcystis biomass and microcystin concentrations in Ugandan lakes
Phosphorus enrichment carbon depletion contribute
<
2014/4/2
We investigated the factors influencing cyanobacterial biomass and microcystin (MC) concentrations in several
Ugandan lakes from September 2008 to February 2009. We characterized thermal structure, l...

Carbon cycling hysteresis permeable carbonate sands over a diel cycle ocean acidification
<
2014/4/2
Dissolved inorganic carbon, dissolved oxygen, H+, and alkalinity fluxes from permeable carbonate sediments at Heron Island (Great Barrier Reef) were measured over one diel cycle using benthic chambers...
Revealing organic carbon sources fueling a coral reef food web in the Gulf of Mexico using stable isotopes and fatty acids
Revealing organic carbon sources coral reef food web Gulf of Mexico stable isotopes fatty acids
<
2014/4/2
Carbon and nitrogen stable isotopes and fatty acids (FAs) revealed primary producer organic carbon sources that fuel a coral reef food web with river influence. A stable isotope mixing model was used ...
