Summary of Field Work: |
Research Cruises: Two research cruises will be carried out during this study project.
1. Pacific Transect - The first cruise is a north/south transect in the Pacific. The requested track is essentially the same as that for BLAST I [Lobert et al., 1996; King et al, 2002] with a northern west coast departure port (e.g. Seattle, WA) and arrival in Punta Arenas, Chile. We will make continuous underway measurements of the concentration of methyl bromide and a suite of halocarbons and alkyl nitrates in air and in surface seawater, as well as analyze depth profile samples for the same compounds. The depth profiles will extend through the seasonal thermocline to approximately 1000m and will be collected approximately every 2 degrees of latitude for a total of ~50 profiles.
