Centre for Climate Research and development (CCRD) has organized a talk on “Marine oil spill detection using synthetic aperture radar over Indian Ocean” on 25 August 2022 (Thursday) at 2:30 pm in video conference room of Junaid Zaidi Library, CUI Islamabad to participate in talk.

Ms. Saima Naz was the moderator of the talk. She is a GIS Expert at the Centre for Climate Research and Development (CCRD), COMSATS University Islamabad, Pakistan. She has done her MS in GIS & Remote Sensing from the Department of Meteorology, CUI. Currently, she is involved in several research projects related to climate change, environmental issues, and solutions. She has served as a GIS manager at Geomatic Services and completed the first phase of the Prime Minister’s project of Cadastral mapping and digital land records.

She explained that four oil spill events over the Indian Ocean including Chennai, Sharjah, Al Khiran and Mubarak Village were analyzed using Sentinel-1 satellite data. General National Oceanic and Atmospheric Administration (NOAA) Operational Modeling Environment (GNOME) model was utilized for oil spills trajectory production, whereas oil spills weathering processes were modeled using Automated Data Inquiry for Oil Spill (ADIOS). Synthetic Aperture Radar (SAR) based oil spill detection technique provided reliable results at the wind speed between 3 to 9 m/s for all events. Maximum oil spill movement (33 km) from the source point was observed in the Al Khiran, whereas the evaporation rate of crude (degraded) oil was observed as high (low). The Near Real Time (NRT) detection of oil spill using SAR imagery needed high computational power, however, provided better results. This study concluded that SAR-based oil spill detection is a cost-effective technique and can be utilized for the mapping of oil spills.
