The NOAA/CMDL Bromine Latitudinal Air/Sea Transect III (BLAST III)
cruise was conducted between February 22nd and April 7th, 1996 from
McMurdo, Antarctica, along the coast and through the ice of Antarctica
to Punta Arenas, Chile. This cruise was a continuation of previous
BLAST cruises. The main focus on these expeditions has been the
measurement of methyl bromide and a suite of other methyl ... halides,
very similar to the setup during BLAST II. The ship Nathaniel Palmer,
used for the BLAST III expedition, is operated by Antarctic Support
Associates which headquarters located in Englewood, Colorado.
Compounds measured include: HCFC-22 (CClF3), CFC-11, -12, -113, and
-114, methyl chloride (CH3Cl), methyl bromide (CH3Br), methyl iodide
(CH3I), methyl chloroform (CH3CCl3), Halon-1211 (CBrClF2), carbon
tetrachloride (CCl4), dibromomethane (CH2BR2), perchloroethylene
(C2Cl4), bromoform (CHBr3), and nitrous oxide (N2).
