  16. 2003 Terrain-Following Ocean Models Users Workshop 2. The Southeastern Brazilian Coast 2.3. Center For Oil Spill Monitoring at Sea - CeMOM In 2001 the Center for Oil Spil Monitoring at Sea (CeMOM) of the Brazilian Petroleum Agency was created The mission of CeMOM is to monitor natural and accidental oil spills in Brazilian coast > LAMMA \ UFRJ www.lamma.ufrj.br

  17. 2003 Terrain-Following Ocean Models Users Workshop 2. The Southeastern Brazilian Coast 2.3. Center For Oil Spill Monitoring at Sea - CeMOM The detection of oil is made through SAR images Once detected an oil spill trajectory forecast is performed > LAMMA \ UFRJ www.lamma.ufrj.br
