HATS has been investigating the air-sea exchange of trace gases since
1987 by measuring atmospheric and dissolved amounts of nitrous oxide, organic
halogens, and other climatically important gases in and over the oceans.
Research cruises average about one per year and usually span a wide geographical
range. The purpose of these cruises is to measure a latitudinal gradient
or to cover a wide geographic area for all compounds in the marine atmosphere
and to compare these data to those from CMDL observatories, to quantify
the ocean's effect on the gases in the surface and deep waters, and to
determine possible sources and/or sinks for the gases in the ocean.
