Tropical Cyclone Triggers PSC Shifts in the Arabian Sea

EasyChair Preprint 9590

Abstract

Of the many oceanic ecosystems experiencing seasonal and climate-driven changes worldwide, the Arabian Sea (AS) stands out as the one with the most dramatic and extreme changes of all. However, the phytoplankton community distribution pattern and environmental adaptation to the extreme events in the Arabian Sea are less explored. Hence these features of the Arabian Sea and the fact that no comprehensive studies have been attempted to investigate the phytoplankton structure based on their size (micro- >20 μm, nano- 2 – 20 μm and picoplankton- < 2 μm) in this regional basin provided an opportunity to explore and understand the tropical cyclone influence on the phytoplankton size classes (PSC) distribution in the AS. The aim of this study is to investigate the phytoplankton size classes (PSC) distribution pattern in the AS during tropical cyclone events through a three-component approach and reconstructed chlorophyll-a datasets. The study revealed interesting results not reported earlier. The cyclone influences PSC variations observed in the AS revealed that the short extreme events regulate the PSC changes in the Arabian sea by controlling the physical drivers.
