Abstract: Of the many anthropogenic and climate-driven changes being reported in oceanic ecosystems worldwide, the recent advent of the green Noctiluca scintillans (herein after Noctiluca) as the dominant bloom forming organism represents the most dramatic and extreme of all. Large widespread and intense blooms of Noctiluca have now become a common feature in the Arabian Sea and in many other tropical coastal ecosystems of southeast Asia that come under the influence of the Indian monsoons. In the Arabian Sea outbreaks of Noctiluca blooms have been attributed to the seasonal shoaling of hypoxic and low pH waters. It recent rapid range expansion has been attributed to ocean stratification and warming Because Noctiluca is not a preferred food for zooplankton, its emergence at the base of the food chain represents a threat to many countries where coastal marine resources are of great economic and cultural significance.
This presentation will highlight new results from a satellite and coupled physical biological modeling effort called DISCO aimed at 1) investigating the origens of Noctiluca and its unique ecophysiological characteristics and, 2) developing Noctiluca specific ocean color algorithms and 3) developing based decision support tools specifically geared towards mitigating large socio-economic losses being caused by massive Noctiluca blooms along the coast of the Sultanate of Oman.
