B ROCKMANN C ONSULT BallastWater ESA UCM Ballast Water Risk * Hamburg * Ballast Water Exchange Risk Index Recommendations of the IMO Ballast Water Convention for ballast water exchange areas –Distance > 50nm –Depth > 200m –No turbid water –No outbreaks / HABs –Currents away from land –No sensitive aquatic areas –Closest to ship routes Utilisation of remote sensing data where available and suitable –Chlorophyll concentration –Turbidity –Suspended matter –Temperature Transparency

B ROCKMANN C ONSULT BallastWater ESA UCM Ballast Water Risk * Hamburg * Assumptions Risk Index Model Highly turbid waters  high risk Near the coast  high risk Near protected areas  high risk Shallow waters  high risk Drift to the coast  high risk High chlorophyll concentration  high risk High suspended matter  high risk High CHL / turbidity at drift position  high risk Low difference between source and destination area (Salinity, Temperature)  high risk
