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 into the ocean in this area. The North Atlantic acted as a sink of the atmospheri...

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 into the ocean in this area. The North Atlantic acted as a sink of the atmospheric gas during the spring, a source during the summer, and a weak sink during the fall. The annual air-sea flux of methyl bromide from the North Atlantic area between 30 degrees N and 60 degrees N (approximately 15.4x10(6) km(2)) was estimated to be in the range of -0.3 to -0.6 Gg y(-1), with the methyl bromide flux varying between -4.0x10(6)+/- 1x10(6) g d(-1), 1.6x10(6)+/- 0.6x10(6) g d(-1), and -0.6x10(6)+/- 0.4x10(6) g d(-1) in spring, summer, and fall, respectively.
