Spatial distribution of suspended and dissolved sediment associated with granite mining activity in the North Natuna Sea

Mining typically result in changes to the environment, which is through mine drainage flows reach the marine environment. Coastal regions are susceptible to contamination because of their dynamic position between land and sea. Mining drainage has strong consequences on the downstream marine environment, not only during the period of the mining activities, but also after their end. In this contribution, we report new and important information about suspended and dissolved sediment that flowed out to the North Natuna Sea from granite mining activity.
