Data Access

R/V Moana Wave oceanographic data are available from the TOGA COARE
International Project Office (TCIPO). Data can be accessed via anonymous FTP
from tcdm.coare.ucar.edu in subdirectory
pub/COARE_DATA/ocean_mixing/Moana_chamel. Data are also available upon request
from NOAA's National Oceanographic Data Center (NODC) in Washington, D.C.

Background

The data were obtained during leg 2, aboard the R/V Moana Wave, which remained
approximately stationary at 1.75S, 156E from 20 December 1992 to 11 January
1993 during COARE.

Currents were measured from shipboard ADCP, with frequency 150 kHz, bin length
4 m and pulse length 8 m. The remaining quantities were measured using the
CHAMELEON microstructure profiler, which executed 6-8 profiles per hour during
most of the cruise. (Profiling was suspended for about one hour each day near
local noon (0100 GMT) for other ship operations.)

The accompanying files contain temperature, salinity, density, zonal and
meridional currents, and dissipation rates for turbulent kinetic energy and
temperature variance.

Data File Information

Directory name: Moana_Chamel
Number of data files: 7
Dataset format: ASCII
Dataset volume: 532 KB

File Format

Each ASCII file contains approximately 550 rows of data, each of which pertains
to a single hour. The first column gives the time at the center of the hour as
year day 1992, i.e., midnight GMT, 1 January 1992 = 1.0. Day 355 = 20 December.
The remaining 63 columns give data for the depth bins centered at 2 m, 6 m, 10
m, ...

Missing data is indicated by the value 999.0.

Data Processing

Data have been averaged into bins spanning one hour and 4 meters in the
vertical. The first depth bin is centered at 2 m.

Collection of this data was funded by NSF grant ATM-9110552.
