Figure 1. BLAST III cruise track from McMurdo, Antarctica, to Punta Arenas, Chile. Numbers along the cruise track indicate the Julian day of year 1996.

Figure 2. Measurements of methyl bromide in air (a), air equilibrated with surface water (b), and the resulting saturation anomaly (c) for both the GC/MS and the GC/ECD systems. The shaded area in panel (c) represents the saturation anomaly, corrected for physical effects, calculated from the GC/MS saturation anomaly (black line).
