Methyl iodide distribution in the ocean and fluxes to the atmosphere
(1999-05)
Methyl iodide concentrations have been measured in air samples, surface, and subsurface waters of the NW Atlantic, NE Atlantic, and Pacific Oceans. They are shown to be substantially oversaturated in all surface waters. ...
Natural emissions of chlorine-containing gases: Reactive Chlorine Emissions Inventory
(1999-04)
Although there are many chlorine-containing trace gases in the atmosphere, only those with atmospheric lifetimes of 2 years or fewer appear to have significant natural sources. The most abundant of these gases are methyl ...
A new measurement of CO sub(2) eddy flux in the nearshore atmospheric surface layer
(1991)
Fluxes of CO sub(2) in the atmospheric surface layer have been measured at a shoreline site by the eddy correlation method using a new CO sub(2) sensor with greater sensitivity than the ones used in earlier studies. In ...
Ocean-atmosphere exchange of methyl bromide: NW Atlantic and Pacific Ocean studies
(1998-07)
Measurements of methyl bromide partial pressure and concentration in surface water and air samples in the NW Atlantic Ocean in July 1995 and the Pacific Ocean in October 1995 are presented, Mean atmospheric mixing ratios ...
Effect of the nonlinearity of the carbonate system on partial pressure of carbon dioxide in the oceans
(1995-04)
Partial pressure of CO sub(2) is a nonlinear function of several seawater properties. Due to the nonlinearity in this relationship, the partial pressure of a uniform ocean would be different from that of a nonuniform ocean ...
Measurements of methyl chloride in the Northwest Atlantic
(American Geophysical Union, 1994-04)
Methyl chloride was measured directly in seawater using a purge and trap system and gas chromatography with electron capture detection. The results indicate that surface waters of the northwest Atlantic are a source of ...
A description of water types on the Mackenzie Shelf of the Beaufort Sea during winter
(1992)
For a number of years during the 1980s, observations of the physical and chemical properties of seawater in the southeastern Beaufort Sea have been acquired in late winter. The most complete data set, from 1987, has been ...
Photochemical Production of Methyl-Iodide in Seawater
(1994-08)
It is generally accepted that methyl iodide is a major contributor to the flux of iodine from the ocean to the atmosphere, but its sources in the ocean are largely unknown, an exception being production by certain species ...
Composite global emissions of reactive chlorine from anthropogenic and natural sources: Reactive Chlorine Emissions Inventory
(1999-04)
Emission inventories for major reactive tropospheric Cl species (particulate Cl, HCl, ClNO2, CH3Cl, CHCl3, CH3CCl3, C2Cl4, C2HCl3, CH2Cl2 and CHClF2) were integrated across source types (terrestrial biogenic and oceanic ...
Methyl-Chloride (Ch3cl) Production in Phytoplankton Cultures
(1995-01)
Unialgal nonaxenic cultures of seven species of phytoplankton, including both warm- and cold-water organisms, were examined under halocarbon-clean conditions for the production of CH3Cl. Incubations of all species showed ...
