Description 348-353
A bio-physical model was developed to estimate zooplankton production in
the Arabian Sea using satellite derived
chlorophyll concentration (CC) and sea surface temperature (SST). For this, US
Joint Global Ocean Flux Study (US
JGOFS) 1995 cruises in-situ data has been used. A 3D plot was generated using
in-situ measured chlorophyll, temperature and zooplankton bio-mass.  Scatter plot indicated linear and exponential
relationship between CC - zooplankton biomass, temperature and zooplankton,
respectively.  A typical range of 24º-26º
C water temperature was found preferable for zooplankton production. Based on
this study a multiple regression analysis was carried out to derive
coefficients for the development of algorithm. 
Correlation co-efficient (r2) of multiple regression analysis
was 0.78. An empirical algorithm was developed using these co-efficient. This
algorithm was applied to Oceansat-1 derived chlorophyll concentration and
NOAA-AVHRR derived SST to generate zooplankton images showing zooplankton
biomass distribution and concentration. Model was validated through synchronous
in-situ observations. Zooplankton biomass was
measured on board Sagar Kanya and Sagar Sampda in the Arabian
Sea. Regression analysis indicated co-relation co-efficient (r2)
= 0.74.
