Current data measured during a dredge experiment during RV SONNE cruise SO268/2 in the German license area, CCZ, NE Pacific Ocean

DOI

Expedition SO268 was part of the JPI Oceans project MiningImpact to assess the environmental impacts of deep sea mining of polymetallic nodules in the Clarion Clipperton Zone (CCZ). A sediment plume monitoring operation was conducted as part of this expedition. This plume was created by a dredge on 11 April 2019 between 6:30 to 19:00 UTC. Monitoring of the baseline conditions, active plume and post-disturbance effects was achieved by a sensor array of optical and acoustical sensors on platforms spread out around the plume creation site. This dataset contains calibrated acoustical measurements of this plume array acquired by 7 acoustic profilers (AQD/ADCP).
