Seasonal and spatial variations in methyl chloride in NW Atlantic waters
 Methyl chloride concentrations were measured in the upper 200 m of the water column of the NW Atlantic during three cruises along the same track in spring, summer and fall of 2003. Distinct seasonality was apparent, ...
Dichloromethane in North Atlantic waters
 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 ...
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 ...
Aerobic hydrogen production and dinitrogen fixation in the marine cyanobacterium Trichodesmium erythraeum IMS101
Rates of hydrogen production and acetylene reduction were measured in aerobic cultures of the marine cyanobacterium Trichodesmium erythraeum IMS101 grown in a supplemented seawater medium low in combined inorganic nitrogen. ...

An isotopic labeling method for determining production of volatile organohalogens by marine microalgae
An isotopic method has been developed to establish the biological production of volatile organohalogens. The marine microalgae Porphyridium purpureum and Dunaliella tertiolecta were grown in seawater medium containing ...
Methyl iodide in the NW Atlantic: Spatial and seasonal variation
While the global ocean is an important source of atmospheric methyl iodide (CH(3)I), the major producers of CH(3)I within the ocean remain unclear. During a seasonal study in the NW Atlantic, the relationship between CH(3)I ...
