Discharge of drill cuttings in the Arctic seas and responses of bottom fauna: bivalve Mytilus edulis L.
Abstract Drill cuttings are the largest solid waste of drilling operations. Onsite discharge of drill cuttings into the marine environment is relevant and can be permitted under certain conditions and regulations. Environmental impact of the on-site discharge of drill cuttings is poorly understood f...
