List of Figures
Figure 1. Arabian Sea standard cruise track with the station locations repeating for the
process cruises, and an array of current meter moorings: The o, +, and * indicate,
respectively, long, intermediate and hydro stations. The symbol designates sediment
trap moorings. The smaller circles centered about 15.50N, 61.50E represent the locations of
the five long-term moorings. 2
Figure 2. The ADCP regions of the Arabian Sea, Bay of Bengal, and western portion of
the Indonesian Archipelago with which configuration file controls the operation of the
ADCP. The configuration regions include possible ports of call and the continental shelves
as well as the open ocean of the Arabian Sea and Bay of Bengal. 5
Figure 3. Plot of the difference between the partially calibrated backscatter intensities
from Beam #1 and the mean intensities from all four beams when the rms difference was
greater than 1.5 dB. The data was taken from cruise TN039. The occurrence of these
relatively large differences is restricted to periods when the ship is on station and appear to
reflect inhomogeneities in the small-scale distribution of fish and/or plankton. The bin
length is 8 meters and the first bin is centered at a depth of approximately 22 meters.
Figure 4. Scatter plot of the calibrated backscatter intensity from Beam #1 versus the
average calibrated backscatter intensity from all four beams from profiles where the rms
differences between the individual beams and the beam-averaged profiles were less than
or equal to 1.0 dB. 14
Figure 5. Cruise map of the northeast monsoon JGOFS process cruise, TN043. The RV
T.G. THOMPSON left Muscat on January 8, 1995 and returned on February 4, 1995.
Numbers along the track represent sections and stations for vector and contour plottings
which are shown in Appendix C. The corresponding positions and the start and end of
times are tabulated in Appendix A. 16
Figure 6. Cruise map of the second ONR/NRL SeaSoar cruise, TN044. The RV T.G.
THOMPSON left Muscat on February 8,1995 and returned on February 25, 1995. Below is
the same as Figure 5. 17
Figure 7. Cruise map of the inter-monsoonal JGOFS process cruise, TN045. Included in
this cruise is the deviation to Abu Dubai for repairs between February 28 and April 13,
1995. The RV T.G. THOMPSON left Muscat for the process cruise itself on March 14 and
returned on April 10, 1995. Below is the same as Figure 5. 18
Figure 8. Cruise map of the mooring turn-around cruise, TN046. The RV T.G.
THOMPSON left Muscat on April 14 and returned on April 29, 1995. Below is the same as
Figure 5. 19
