The convergence of warm and cold oceanic currents creates nutrient-rich waters, enhancing the productivity of marine ecosystems. This phenomenon, often referred to as upwelling, facilitates the growth of phytoplankton, the foundation of the marine food web, attracting various fish species. Consequently, areas where these currents meet, such as coastal upwelling zones, become significant fishing grounds, supporting global fisheries and economies, as highlighted in standard resources like NCERT textbooks and environmental studies.
