Impact of a newly observed recurring eddy on the western Bay of Bengal productivity 

Mesoscale eddies have a significant impact on the biological productivity in the Bay of Bengal (Eastern Indian Ocean). However, we do not currently have a complete understanding of them. The Bay of Bengal is a region that is highly dependent on fishing for its population’s survival, with surrounding countries such as Bangladesh depending on fish from the bay for approximately 60% of their consumed animal protein, and hence understanding any changes in this biological productivity is important. In this work, using 25-42 years of satellite data and the py-eddy-tracker eddy detection algorithm (Mason et al., 2014), we observe a yearly recurring mesoscale eddy (called hereafter the Odisha Eddy) on the western coast of the Bay of Bengal, which was noted…
