Study Shows North Atlantic Ocean CO2 Storage Doubled Over Last Decade
carbon dioxide ocean life fossil fuels
2016/2/23
A University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows that the North Atlantic absorbed 100 percent more man-made carbon dioxide over the last decade, compared ...
Genetic switch lets marine diatoms do less work at higher CO2
Genetic switch marine diatoms higher CO2
2015/6/18
Diatoms in the world’s oceans exhale more oxygen than all the world’s rainforests. These tiny drifting algae generate about 20 percent of the oxygen produced on Earth each year, and invisibly recycle ...
The responses of eight coral reef calcifiers to increasing partial pressure of CO2 do not exhibit a tipping point
The responses eight coral reef calcifiers increasing partial pressure CO2 do not exhibit a tipping point
2014/4/2
The objective of this study was to investigate whether a tipping point exists in the calcification responses of coral reef calcifiers to CO2. We compared the effects of six partial pressures of CO2(PC...
Increased cellular brevetoxins in the red tide dinoflagellate Karenia brevis under CO2 limitation of growth rate: Evolutionary implications and potential effects on bloom toxicity
Increased cellular brevetoxins Karenia brevis
2014/4/2
Karenia brevis blooms impair human health, marine ecosystems, and coastal economies in the Gulf of Mexico
via their production of carbon-based neurotoxins (brevetoxins), which contain no nitrogen (N)...
Effects of CO2 and their modulation by light in the life-cycle stages of the coccolithophore Emiliania huxleyi
Effects of CO2 their modulation light in the life-cycle stages coccolithophore Emiliania huxleyi
2014/4/4
The effects of ocean acidification on the life-cycle stages of the coccolithophore Emiliania huxleyi and their modulation by light were examined. Calcifying diploid and noncalcifying haploid cells (Ro...
Ocean acidification hot spots: Spatiotemporal dynamics of the seawater CO2 system of eastern Pacific coral reefs
Ocean acidification hot spots Spatiotemporal dynamics the seawater CO2 system eastern Pacific coral reefs
2014/4/16
Seawater CO2system dynamics were assessed from eastern Pacific reef sites in Panama ′ over 5 consecutive years(2003–2008) and twice in the Gala ′ pagos Islands (2003 and 2009). The seawater CO2system ...
Elevated CO2 increases sensitivity to ultraviolet radiation in lacustrine phytoplankton assemblages
Elevated CO2 increases sensitivity ultraviolet radiation lacustrine phytoplankton assemblages
2014/4/17
This study tests the effects of elevated CO2 and ultraviolet radiation (UVR) on phytoplankton photosynthesis through in situ incubations in Lake Giles, Pennsylvania. In a first experiment, CO2 was sup...
High abundance and dark CO2 fixation of chemolithoautotrophic prokaryotes in anoxic waters of the Baltic Sea
High abundance dark CO2 fixation chemoli thoau trophic prokaryotes anoxic waters Baltic Sea
2014/4/21
We determined the abundance and distribution of chemolithoautotrophic prokaryotes in the redoxcline in two basins (Gotland Deep, Landsort Deep) of the central Baltic Sea by combining dark CO2 fixation...

We determined the abundance and distribution of chemolithoautotrophic prokaryotes in the redoxcline in two basins (Gotland Deep, Landsort Deep) of the central Baltic Sea by combining dark CO2 fixation...
11 July 2007,Coral reefs are at risk of going soft, quite literally turning to mush as rising carbon dioxide levels prevent coral from forming tough skeletons, according to UQ research.
Biogas (CO2, O2, dimethylsulfide) dynamics in spring Antarctic fast ice
Biogas dynamics in spring Antarctic fast ice
2014/4/22
We studied the temporal variations of CO2, O2, and dimethylsulfide (DMS) concentrations within three environments (sea-ice brine, platelet ice-like layer, and underlying water) in the coastal area of ...
CO2 control of Trichodesmium N2 fixation, photosynthesis, growth rates, and elemental ratios: Implications for past, present, and future ocean biogeochemistry
CO2 control Trichodesmium N2 fixation photosynthesis growth rates elemental ratios past present future ocean biogeochemistry
2014/4/22
Diazotrophic marine cyanobacteria in the genus Trichodesmium contribute a large fraction of the new nitrogen entering the oligotrophic oceans, but little is known about how they respond to shifts in g...
Relative importance of CO2 recycling and CH4 pathways in lake food webs along a dissolved organic carbon gradient
CO2 recycling CH4 pathways lake food webs a dissolved organic carbon gradient
2014/5/4
Terrestrial ecosystems export large quantities of dissolved organic carbon (DOC) to aquatic ecosystems. This DOC can serve as a resource for heterotrophic bacteria and influence whether lakes function...
Analysis of the seawater CO2 system in the barrier reef-lagoon system of Palau using total alkalinity-dissolved inorganic carbon diagrams
the seawater CO2 system barrier reef-lagoon system total alkalinity-dissolved inorganic carbon diagrams
2014/5/4
We studied the seawater carbon dioxide (CO2) system in the Palau coral reef by measuring total alkalinity (TA) and total dissolved inorganic carbon (DIC). Variation in the CO2 system on the reef flat ...
