Q.11 Which among the following statements regarding Upwelling are correct ? 1) It is associated with the divergence of currents that bring deeper, colder, nutrient rich waters to the surface 2) It replaces nutrient-depleted surface water 3) Nutrient-rich upwelled water stimulates the growth and reproduction of primary producers 4) wind & Coriolis effects affects the Upwelling Codes: A) 1,3,4 B) 2,3,4 C) 1,2,3 D) 1,2,3,4 Ans. D Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-depleted surface water. The nutrient-rich upwelled water stimulates the growth and reproduction of primary producers such as phytoplankton. Due to the biomass of phytoplankton and presence of cool water in these regions, upwelling zones can be identified by cool sea surface temperatures (SST) and high concentrations of chlorophyll-a. The increased availability in upwelling regions results in high levels of primary productivity and thus fishery production. Approximately 25% of the total global marine fish catches come from five upwellings that occupy only 5% of the total ocean area. Upwellings that are driven by coastal currents or diverging open ocean have the greatest impact on nutrient-enriched waters and global fishery yields.
