Oil spill trajectory prediction assessment using multi model ocean currents - case study of MT Dawn Oil spill 2017

Abstract 684276 An assessment was carried out to judge the performance of modeled ocean currents in oil spill trajectory prediction. Ocean circulation is key factor determining drift pattern spilled marine pollutant. General National Oceanic and Atmospheric Administration Operational Modeling Environment (GNOME), an model, diagnostic mode set for simulating Heavy Fuel Oil (HFO). On 28 January 2017, 0345 hrs, Indian Standard Time (IST), approximately 196.4 MT HFO due vessel collision. The model run during 28-Jan-2017 05-Feb-2017 with 196 tons HFO. Wind velocity fields were obtained from European Centre Medium-Range Weather Forecasts (ECMWF). High resolution Forecasting reanalysis System (HOOFS) two ups such as (IO) Bay Of Bengal (BOB). current also Hybrid Co-ordinate Model (HYCOM) Global Data Assimilation (GODAS) based Modular (GM4P1). patterns simulated individually spillage Dawn vessel, by forcing GNOME above said wind currents. Radar data 29-Jan-2017, Sentinel -1A processed detecting slicks. respective compared slick signatures on 29-Jan-2017. It found that while using HOOFS_BOB better agreement observed Unlike other patterns, offshore spread slicks are well captured HOOFS_BOB. This paper illustrates method prediction various validating ground truth. emphasize need assessing model.
