             abstract = "On November 5th 2015, the Fundaos dam collapsed in Mariana, Minas 
                         Gerais state, releasing approximately 55 million/m³ of tailings to 
                         the coast and marine conservation units. The dams sediment plume 
                         carried by the River Doce could alter local physical conditions 
                         and our study focuses on the changes in turbidity. We made use of 
                         a specific method, MODIS-Aqua images and meteorological data to 
                         assess and quantify turbidity before and after the disaster. Our 
                         results show that the plume dispersion and turbidity are very 
                         sensitive to precipitation rates and the predominating winds. 
                         Before the disaster, close to the river mouth, turbidity values 
                         can sometimes reach around 900 FNU, whereas after the disaster 
                         this variable reached values beyond the 1,000 FNU, suggesting the 
                         influence of the tailings dam. We also generated a map that shows 
                         the percentage change in turbidity after the incident, based on 
                         maximum value of turbidity per pixel observed before. We observed 
                         an increase of more than 600% in turbidity during different 
                         periods. Our data suggest that turbidity was indeed altered at 
                         further regions, reaching both conservation units of Costa das 
                         Algas and Santa Cruz. The tailings plume showed a strong influence 
                         on turbidity until late January of 2016, weakening from February 
                         on.",
