Bromoperoxidase and iodoperoxidase enzymes and production of halogenated methanes in marine diatom cultures
Halogenated methanes produced in the oceans are important as carriers of chlorine, bromine, and iodine into the atmosphere. There they play roles in the regulation of ozone in the stratosphere and perhaps in the Arctic ... -
Composite global emissions of reactive chlorine from anthropogenic and natural sources: Reactive Chlorine Emissions Inventory
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 ... -
Dichloromethane in North Atlantic waters
[1] Dichloromethane is an atmospheric trace gas that has a tropospheric lifetime on the order of 5 months and has major anthropogenic sources. Evidence has been presented for an oceanic source. This paper reports measurements ... -
Methyl iodide distribution in the ocean and fluxes to the atmosphere
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
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 ... -
Ocean-atmosphere exchange of methyl bromide: NW Atlantic and Pacific Ocean studies
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 ... -
Production of chlorinated hydrocarbons and methyl iodide by the red microalga Porphyridium purpureum
Two experiments were performed using axenic batch cultures of the red microalga Porphyridium purpureum. The cultures were grown in sealed 5-liter glass vessels under a high-purity artificial atmosphere and analyzed for the ... -
A seasonal study of methyl bromide concentrations in the North Atlantic (35 degrees-60 degrees N)
Methyl bromide concentrations in and over the North Atlantic were examined during spring, summer, and fall 2003. The results demonstrate that seasonality plays a great role in controlling methyl bromide fluxes from and ...
