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 in permeable carbonate sands over a diel cycle: Implications for ocean acidification
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 ...
Groundwater-derived dissolved inorganic and organic carbon exports from a mangrove tidal creek: The missing mangrove carbon sink?
Groundwater-derived dissolved inorganic organic carbon exports mangrove tidal creek
2014/4/2
A majority of the global net primary production of mangroves is unaccounted for by current carbon budgets. It has been hypothesized that this “missing carbon” is exported as dissolved inorganic carbon...
Removal of dissolved inorganic carbon in the Yellow River Estuary
dissolved inorganic carbon Yellow River Estuary
2014/4/2
The Yellow River of China runs mainly through an arid and semiarid midlatitude region that has experienced
substantial anthropogenic and climatic change. This area includes the carbonate-rich Loess P...
Diversity trumps acidification: Lack of evidence for carbon dioxide enhancement of Trichodesmiumcommunity nitrogen or carbon fixation at Station ALOHA
Diversity trumps acidification Lack of evidence carbon dioxide enhancement Trichodesmiumcommunity nitrogen carbon fixation Station ALOHA
2014/4/2
We conducted 11 independent short-term carbon dioxide (CO2) manipulation experiments using colonies of the filamentous cyanobacteria Trichodesmiumisolated on three cruises in the North Pacific Subtrop...
Oxygen in the deep Strait of Georgia, 1951–2009: The roles of mixing, deep-water renewal, and remineralization of organic carbon
deep Strait of Georgia The roles of mixing
2014/4/2
The concentration of oxygen in the deep Strait of Georgia has declined at a rate of 0.45–1.3 mmol L21
yr21
since 1971 and now seasonally approaches thresholds of biological tolerance. The decline ha...
When scientists discuss global change, they often focus on the amount of carbon in the atmosphere and vegetation. But soil contains more carbon than air and plants combined. This means that even a min...

Symbiotic fungi
2014/3/17
AUSTIN, Texas — Microscopic fungi that live in plants' roots play a major role in the storage and release of carbon from the soil into the atmosphere, according to a University of Texas at Austin rese...

Shape transition unstrained flattest single-walled carbon nanotubes under pressure
2014/9/24
Single walled carbon nanotube’s (SWCNT’s) cross section can be flattened under hydrostatic pressure. One example is the cross section of a single walled carbon nanotube successively deforms from the o...
利用瓦里关全球本底站和番禺气象局站地面观测的CO2浓度资料对改进的Carbon Tracker-2010（CT-2010）模式系统进行了验证.结果显示，CT-2010能较好地反映近地层CO2浓度的分布状况，在瓦里关地区，模拟值与观测值的决定系数（R2）为0.584，残差为4.49 μmol·mol-1，相对误差为1.18%；在珠三角地区，上述3个参数值分别为0.430、13.89 μmol·mol...
