What Corals are Dying to Tell Us About CO2 and Ocean Acidification
Ocean Acidification CO2
<
2015/7/22
Emissions of carbon dioxide are causing the oceans to become more acidic. Recent experiments show that this ocean acidification threatens many ocean ecosystems. The ancient past may provide a cautiona...
Deep Ocean Carbonate Chemistry and Glacial-Interglacial Atmospheric CO2 Changes
Deep Ocean Carbonate Chemistry Glacial-Interglacial Atmospheric CO2
<
2015/7/17
Changes in deep ocean carbonate chemistry have profound implications for glacial-interglacial atmospheric CO2 changes. Here, we review deep ocean carbonate ion concentration ([CO32–]) changes based on...
A Time-Series View of Changing Ocean Chemistry Due to Ocean Uptake of Anthropogenic CO2 and Ocean Acidification
Time-Series View Changing Ocean Chemistry Due Ocean Uptake Anthropogenic CO2 Ocean Acidification
<
2015/7/17
Sustained observations provide critically needed data and understanding not only about ocean warming and water cycle reorganization (e.g., salinity changes), ocean eutrophication, and ocean deoxygenat...
Ocean Acidification:The Role of CO2.
Research Priorities for Understanding Ocean Acidification: Summary From the Second Symposium on the Ocean in a High-CO2 World
Carbon dioxide sea world ocean acidification oceanography
<
2015/7/6
The first symposium on "The Ocean in a High-CO2 World" in 2004 proved to be a landmark event in our understanding of the seriousness of ocean acidification, as reported in Oceanography (Cicerone et al...
Nutrient Cycles and Marine Microbes in a CO2-Enriched Ocean
Ocean carbon cycle element carbon dioxide ocean acidification Marine nutrient biogeochemical microorganisms
<
2015/7/6
The ocean carbon cycle is tightly linked with the cycles of the major nutrient elements nitrogen, phosphorus, and silicon. It is therefore likely that enrichment of the ocean with anthropogenic CO2 an...

<
2015/7/6
The uptake of anthropogenic CO2 by the global ocean induces fundamental changes in seawater chemistry that could have dramatic impacts on biological ecosystems in the upper ocean. Estimates based on t...
An Accounting of the Observed Increase in Oceanic and Atmospheric CO2 and an Outlook for the Future
Carbon dioxide atmosphere ocean burning fossil fuel emissions
<
2015/7/6
Observations of CO2 accumulation in the atmosphere and ocean show that they are approximately equal to the total amount emitted by burning of fossil fuels since 1850. A mass balance calculation is car...
Triple I of CO2 Ocean Sequestration against Ocean Surface Acidification
Triple I CO2 Ocean Sequestration Ocean Surface Acidification
<
2009/3/25
To mitigate the global warming and ocean surface acidification caused by increase of atmospheric CO2 concentration, ocean sequestration of CO2 has been proposed. Because the technology has risks on de...
Postindustrial enhancement of aragonite undersaturation in the upper tropical and subtropical Atlantic Ocean: The role of fossil fuel CO2
Postindustrial enhancement aragonite undersaturation upper tropical subtropical Atlantic Ocean fossil fuel CO2
<
2014/5/14
The dissolution of aragonite particles in the ocean primarily depends on the degree of undersaturation of seawater with respect to that mineral. Most of the upper Atlantic Ocean, particularly north of...
Clams as CO2 generators: The Potamocorbula amurensis example in San Francisco Bay
Clams as CO2 generators Potamocorbula amurensis example San Francisco Bay
<
2014/5/22
Respiration and calcium carbonate production by the invasive Asian clam, Potamocorbula amurensis, were calculated to assess their importance as CO2 sources in northern San Francisco Bay. Production, c...
Dissolution from a liquid CO2 lake disposed in the deep ocean
Dissolution liquid CO2 lake disposed deep ocean
<
2014/5/20
The dissolution from a liquid CO2 lake source located at a flat ocean bottom at 3,000 m depth is investigated. Using the unsteady, two-dimensional advection-diffusion equation, temporal and spatial di...
Biogeochemical and physical factors influencing seawater fCO2 and air-sea CO2 exchange on the Bermuda coral reef
Biogeochemical physical factors seawater fCO2 air-sea CO2 exchange Bermuda coral reef
<
2014/6/9
It is uncertain whether coral reef ecosystems are oceanic sources or sinks of carbon dioxide (CO2). Understanding the complex interactions between biogeochemical and physical processes within reef eco...
