| Abstract | The Sea of Oman is among the fastest-changing tropical marine ecosystems, experiencing a marked loss of plankton biodiversity driven by the rise and range expansion of green Noctiluca blooms. These blooms are linked to Eurasian warming, spreading hypoxia, and ocean acidification. Green Noctiluca, a mixoplankton, is not a preferred food for zooplankton; instead, it competes with them for resources. Its dominance is reshaping the food web and threatening a fisheries-rich ecosystem of substantial socio-economic and cultural importance for the region. This presentation synthesizes insights from laboratory experiments, field observations, and satellite-based remote sensing to reveal the drivers of these seasonal blooms, their expansion, and the risks they pose to regional food security, water quality, and broader national security. We also highlight how this knowledge is being translated into decision-support tools designed to mitigate socio-economic losses and support sustainable blue economy initiatives. |
