Teluk Senunu terletak di pantai selatan Kabupaten Sumbawa Barat, Provinsi Nusa Tenggara Barat. Daerah ini merupakan kawasan pembuangan tailing dari PT Newmont Nusa Tenggara (NNT). Hasil pemeruman di lokasi penyelidikan di sekitar alur pipa tailing memperlihatkan kedalaman dasar laut di sekitar Teluk Senunu bervariasi, pada kedalaman 0 sampai dengan 100 meter dijumpai pada jarak sekitar 3 - 3,25 km dari garis pantai. Keberadaan pipa tailing terluar berada pada kedalaman sekitar 120 meter dari permukaan dasar laut, dan posisi penempatan tailing ini terletak di kawasan Ngarai dengan kedalaman lebih dari 125 meter. Berdasarkan hasil penafsiran data Side Scan Sonar dijumpai adanya 3 jalur pipa tailing yang berada di permukaan dasar laut dengan penyebaran tailing secara lateral melebar sepanjang 1,5 km sejajar dengan tebing Ngarai Senunu. Kata kunci : tailing, Teluk Senunu, Rekaman Seismik, Side scan sonar Senunu bay is located on the southern coast of West Sumbawa Regency, West Nusa Tenggara. This area is a tailings disposal area of the ??PT Newmont Nusa Tenggara (NNT). Results of sounding around the tailing pipe shows the depth of the seafloor around the Senunu bay vary, at a depth of 0 to 100 meters was found at a distance of about 3 to 3.25 km from the coastline. The outer pipe of tailings located at a depth of 120 meters from the sealevel, and tailings placement position is located in the gap with a depth of more than 125 meters. Based on the results of Side Scan Sonar data interpretation, the 3 pipelines of tailings on the sea floor with spread laterally along the 1.5 km wide parallel to the canyon cliffs of Senunu. Key words : tailing, Teluk Senunu, Seismic Record, Side scan sonar
