Oceanographic factors of oil pollution dispersion offshore the Nile Delta (Egypt) using GIS

Oil pollution is a worldwide concern due to the increasing rate of offshore oil production and transport. As the Nile Delta coast is adjacent to the main route of oil transport through the Suez Canal, accidental oil spills along the offshore region may have a tremendous impact on the coastal waters. If the oil slicks reach the coast, the impact should also be significant. This study aimed to map the oceanographic parameters that may affect oil pollution dispersion along the offshore zone of the Nile Delta using geographic information system (GIS) techniques. Oceanographic data (wave patterns, bathymetry data, sea surface temperature (SST), chlorophyll content, phytoplankton concentration, and organic carbon concentration) were used to analyze the characteristics of water at the onset of oil pollution to interpret the dispersion of the oil slick once discharged into the seawater. The results showed that SSTs and the depth of the coastal zone primarily influence the distribution of the other parameters.

Automated summary

Oil pollution is a global concern due to the rise in offshore oil production and transport. A study was conducted to map oceanographic parameters affecting oil pollution dispersion in the offshore zone of the Nile Delta, showing that sea surface temperature and coastal zone depth primarily influence the distribution of other parameters.
