R I T S 8 9 Radiatively Important Trace Species (1989)
The purpose of this cruise was to measure the interhemispheric gradient
of radiatively important trace species in the atmosphere, to quantify the
ocean's effect on these trace gases in the surface waters, to measure the
biological rate of production of dissolved N2O,
and to compare these measurements to those from CMDL observatories.
Methods and list of measured compounds:
Gas chromatograph / electron capture detector

The NOAA Ship Discoverer, R 102, is about 93m long, cruises at about
14-16 knots maximum speed, and is staffed with around 50 crew members with
a maximum capacity of about 40 scientists. It was one of the largest scientific
vessels in the NOAA fleet and operated out of Seattle, Washington until
it was retired in 1996. The main laboratory was located on main deck level
close to the stern. The portholes of this lab can be seen in this picture
left of the ladder from the raft that is tied to the ship.
RITS 89 is shown in magenta through the East Pacific Ocean, out and
back into Seattle, Washington.
