These observations have centred on high-frequency (10-minute) observations of turbidity and flow giving possibly the first such annual data at this sampling frequency on New Guinea Island. The first year of monitoring has demonstrated a marked seasonality in the delivery of suspended sediment from the 5866 km2 Upper Ramu basin, with considerably more natural variability in response within the 6-month wet season. Were new mining operations to release fine sediment (contaminated with heavy metals) into the watercourses of the Upper Ramu, then such shifts in the sediment signal may be, therefore, more identifiable within the dry season. With evidence of an increase in fine sediment load, the Ramu Communities would have a more robust case to request increased monitoring of heavy metal levels within the Ramu and if necessary to request improvements to the erosion and drainage management of mine areas",
