Nutrient availability limits phytoplankton growth throughout much of the global ocean, and this has led scientists to consider fertilizing the ocean with phytoplankton growth‐limiting nutrients. We studied the response of phytoplankton to the addition of natural materials such as rice husk and bamboo leaves through field mesocosm experiments. Rice husk released only SiO 4 4− while the bamboo leaves released SiO 4 4− and also N...

The increasing atmospheric CO 2 concentration in the last few decades has resulted in a decrease in oceanic pH. In this study, we assessed the natural variability of pH in coastal waters off Goa, eastern Arabian Sea. pH T showed large variability (7.6–8.1) with low pH conditions during south‐west monsoon (SWM), and the variability is found to be associated with upwelling rather than freshwater runoff. Considering that marine b...

Fishery along the west coast of India largely depends on pelagic fish such as oil sardines, which are dominant during the south‐west monsoon. However, the response of sardine population to the warming caused by the climatic events such as El Niño/Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) is poorly studied. Here, we hypothesize that the ENSO‐related changes in biogeochemistry can adversely affect the oil sardine...
