So far, however, no such policy has been created to protect carbon storage in the ocean, which is Earth’s largest carbon sink and a central element of our planet’s climate cycle. As a marine biologist, my research focuses on marine mammal behavior, ecology and conservation. Now ...
Murray explains, "We tested two CO2levels, present-day levels and the maximum level of CO2we would see in the ocean in 300 years under a worst-case emissions scenario. The caveat to that is that silversides spawn and develop as larvae and early juveniles in coastal systems that are prone ...
Organic carbon buried in marine sediment serves as a net sink for atmospheric carbon dioxide and a source of oxygen1,2. The rate of organic carbon burial through geologic history is conventionally established by using the mass balance between inorganic a
The reaction rate of the copper-catalyzed oxidation of iodide by oxygen in an aqueous acidic medium is first order in copper and oxygen concentrations, Michaelis-Menten in pH and a complex, asymmetrical bell shaped function in iodide concentrations. A theoretical, multivariate reaction rate equation ...
We report on an application of chemical, physical and biological methods to analyze the changes of carbon dioxide in oceans. Based on the relationships among the oceans, land, atmosphere and sediment with respect to carbon dioxide, the foundation of carbon dioxide in shell-building and ocean ...
Measurements from the Southern Ocean show that particulate organic carbon (POC) concentration is well correlated with the optical backscattering by particles suspended in seawater. This relation, in conjunction with retrieval of the backscattering coefficient from remote-sensing reflectance, provides an algor...
Simulations of the flux of atmospheric carbon dioxide into the ocean show that changes in flux associated with human activities are currently masked by natural climate variations, but will be evident in the near future. See Letter p.469 The world's ocean
Only about 45% of the total CO 2 emitted from fossil fuel burning and land use change stayed in the atmosphere on average during the past few decades. The remaining CO 2 was taken up by the carbon reservoirs (the 'CO 2 sinks') in the ocean and on land. The sinks are sensitive to ...
Transparent Exopolymer Particles (TEP) have received considerable attention since they were first described in the ocean more than 20years ago. This is because of their carbon-rich composition, their high concentrations in ocean's surface waters, and especially because of their ability to promote agg...
Large amounts of atmospheric carbon can be exported and retained in the deep sea on millennial time scales, buffering global warming. However, while the Barents Sea is one of the most biologically productive areas of the Arctic Ocean, carbon retention times were thought to be short. Here we ...
