ISRO satellite reveals El Niño’s growing impact on Pacific waters
- ISRO’s Oceansat-3 found a notable fall in surface chlorophyll-a across the equatorial Pacific in June 2026.
- Weaker trade winds reduced upwelling, cutting the supply of nutrient-rich water reaching the ocean surface.
- Lower chlorophyll-a signals less phytoplankton growth, weakening marine productivity and ocean food webs.
- ISRO says the low-chlorophyll zone may expand further if the developing El Niño intensifies in coming months.
