Spreading and Vertical Structure of the Persian Gulf and Red Sea Outflows in the Northwestern Indian Ocean

In the Indian Ocean, salty water masses from Persian Gulf and Red Sea are important sources of salt, heat, nutrients. Across Arabian Sea, these outflows impact human biological activities, their thermohaline characteristics shapes exhibiting spatial seasonal variability. The knowledge properties is to validate realistic simulations Ocean. A classical approach study track them on specific isopycnal levels. Nevertheless, peaking not always found at a density but rather spread over range. Here, we develop detection algorithm able capture full vertical structure outflows, that applied data set about 126,000 profiles. We thus quantify changes in signatures structures, characterized here by intensity salinity peaks lateral injection fresh waters, describe northwestern undergo several changes, diminishing layering. early stages narrow Oman Aden, present configurations indicative diapycnal mixing. same regions along western edge subject All salt fingering conditions met for lower layers outflows.
