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. For detailed
information, select one of our cruises above and then a topic in
the menu to the left!
