| Description |
Atmospheric deposition of soil dust is an important source of nutrients (especially iron) to the open ocean regions. Every winter (December to March) the Arabian Sea, the northwest part of the Indian Ocean, receives large mineral dust flux from episodic dust storms that occur in the surrounding arid and semi-arid landmass. The region also experiences convection-driven entrainment blooms this time of the year [Madhupratap et al., 1996]. While the mechanism of the convection-driven blooms has been well studied, how far nutrients released from mineral dust flux are important in thriving phytoplankton blooms is what eludes us. By doing a simple spatial correlation between satellite-derived dust optical depth and chlorophyll a (Chl a) concentrations we show that the central Arabian Sea (CAS) can support phytoplankton blooms that may be attributed to the nutrients derived from mineral dust fluxes. This is because CAS is away from the domain of active winter convection thereby having limited oceanic supply of nutrients.
