Cruise Info
===========
Bromine Latitudinal Air/Sea Transect II (BLAST II) 
atlantic expedition in Oct/Nov 1994.

Goal:
=====
This cruise was basically a "sequel" of BLAST 94 in order to verify findings
from the first cruise. In addition to all compounds that were measured during
BLAST 94, we added some other halogenated methanes.


List of (the most important) measured compounds:
================================================
Nitrous Oxide		N2O
Sulfur hexafluoride	SF6
CFC-12			CF2Cl2
Methyl Chloride		CH3Cl
CFC-114			C2F4Cl2 symm
H-1211			CF2ClBr
Methyl Bromide		CH3Br
CFC-11			CFCl3
Methyl Iodide		CH3J
CFC-113			CCl3CF3
ChloroBromoMethane	CH2ClBr
Methyl Chloroform	CH3CCl3
Carbon Tetrachloride	CCl4
DiBromoMethane		CH2Br2
ChloroIodoMethane	CH2ClJ
ChloroDiBromoMethane	CHClBr2
PerChloroEthylene	C2Cl4
Bromoform		CHBr3
DiIodoMethane		CH2J2

Method:
=======
Gas chromatography / electron capture detector (GC/ECD) (N2O, SF6, CFC-12)
Gas chromatography / mass spectrometry (GC/MS) (all others)
both methods (CFC-11, CFC-113, Methyl chloroform, carbon tetrachloride).
