Chapter 6 Conclusion and Recommendation

6.1 Conclusion

From the present study the following conclusions can be drawn-

  • Highest POC was observed during the northeast monsoon, while the lowest was recorded during pre-monsoon months.

  • Monthly POC exhibited an inverse relationship with monthly Sea Surface Temperature (SST), with SST having almost no contribution to the variability of POC in the Bay of Bengal.

  • A positive correlation was found between Chlorophyll-a (Chl-a) and POC in the Bay of Bengal.

  • POC variability was primarily influenced by Chl-a rather than SST, indicating that Chl-a has the greatest contribution to the variation of POC.

  • No statistically significant difference was observed between wind speed and POC (p > 0.05).

  • POC levels were notably high when the prevailing wind vectors were northeasterly and low during southwesterly winds.

  • A moderate positive correlation was identified between in-situ POC values and POC values derived from MODIS-Aqua satellite data.

  • There was a negative correlation between in-situ POC and depth in the Bay of Bengal.

  • POC demonstrated a decreasing trend from the shelf zone to the deep ocean.

6.2 Recommendation

  1. The spatial resolution of MODIS-Aqua satellite is very high. Low-resolution data may provide a more accurate estimation of POC.

  2. It is essential to develop a regional algorithm tailored for the best measurement of POC. This will contribute to more accurate and context-specific assessments.

  3. There is a need for additional facilities to support more intense in-situ field measurements. Increasing the sampling number will enhance the reliability of the collected data for a comprehensive analysis of POC.

  4. Further studies are crucial to address the multitude of factors responsible for POC variability. Understanding these factors will contribute to a more comprehensive and nuanced comprehension of the dynamics influencing POC in the studied region.
