Summary
DATA ACCESS
All SeaSoar data are available upon request from NOAA's National
Oceanographic Data Center (NODC) in Silver Spring, MD
(http://www.nodc.noaa.gov). The data are also archived at the
National Center for Atmospheric Research (NCAR) in Boulder, CO
(http://dss.ucar.edu/pub/toga_coare/).
BACKGROUND - TOGA COARE
TOGA ... COARE was a multidisciplinary, international research effort that
investigated the scientific phenomena associated with the interaction
between the atmosphere and the ocean in the warm pool region of the
western Pacific. The field experiment phase of the program took place
from 1 November 1992 through 28 February 1993 and involved the
deployment of oceanographic ships and buoys, several ship and land
based Doppler radars, multiple low and high level aircraft equipped
with Doppler radar and other airborne sensors, as well as a variety of
surface based instruments for in situ observations.
DATA AVAILABILITY
The following SeaSoar observations were made:
1) R/V Franklin
The Australian R/V Franklin participated in TOGA COARE during the IOP
from 19 November to 19 December 1992 and from 7 January to 7 February
1993 The ship was located inside the Intensive Flux Array (IFA) close
to 155E, 1 30'S, performing "butterfly patterns" centered on a
drifting buoy.
The SeaSoar, equipped with an internal CTD unit, was towed around a
bow-tie shaped track with the bow centered adjacent to the drifting
buoy. The ship speed was about 8 kts and the drifter was passed every
four hours. About twice per day, coinciding with passing the drifter,
the SeaSoar was retrieved and the CTD removed and placed on a Rosette
frame. A CTD was then taken to 200 m depth, with samples collected on
the upcast for calibration purposes.
While deployed, the SeaSoar followed a sawtooth flight path sampling
between the surface and 200 m, doing one cycle in about 7-8
minutes. At times when the SeaSoar was onboard, CTD measurements were
taken regularly (near the drifter) to obtain some continuity in the
dataset.
Whenever the drifter began to head out of the IFA or needed servicing,
it was removed from the water and redeployed. As a result six sets of
data were collected, as outlined below. Temperature, conductivity,
pressure and light data were collected. The light data have not been
processed.

2) R/V Le Noroit
SeaSoar data were collected from the R/V Le Noroit for 12 north/south
sections (5N to 5S) along 156E during the TOGA COARE IOP from 30
December 1992 to 17 February 1993. The towed SeaSoar, which undulated
between the surface and approximately 300 m, surfaced approximately
every 3 km. The SeaSoar carried a Neil Brown Mk III CTD.
SeaSoar data are available for 12 of these north/south sections along
156E. The SeaSoar carried a Neil Brown Mk III CTD. The data are
gridded on 4 m in the vertical and 0.1 degree latitude in the
horizontal.

3) R/V Wecoma
>From 6 November 1992 to 23 February 1993, the R/V Wecoma operated in
butterfly patterns near the IMET buoy in the center of the IFA (2S,
156E). SeaSoar operations were conducted between 1S to 3S and 155E to
157E. Measurements were taken with a Sea-Bird 9/11 plus CTD with
dual-ducted SBE-3 and SBE-4 temperature and conductivity sensors
inside the SeaSoar vehicle. The flow-through sensor duct was pumped by
SBE-5 pumps with the duct intake and outlet on either side of the
lower nose. The intake and outlet for each duct was separated by about
5 cm. The final data are all from the same pair of sensors. Maximum
sampling depth was usually less than 300 m.
+ Cruise 1/W9211A
SeaSoar sampling was done in five tows (numbered 1,3,4,5,6) plus an
aborted tow (number 2):

the fluorometer failed slowly during tow 4 and that data after 23
November are not valid. Data taken during tow 1 with SeaTech
transmissometer are also invalid.
