Processed EM124 swath bathymetry data, eastern Pacific PLUME RAIDERS cruise RR2106 (2021)

Eastern Pacific Ocean swath bathymetry was collected with a Simrad EM124 multibeam sonar system on R/V Roger Revelle during PLUME RAIDERS cruise RR2106 in 2021 (investigators Chris German, Joseph Resing, Scott White). The files were processed in MB-System following standard protocol for navigation, attitude, sound velocity, and bad beams. The data files are in MB-System-compatible format (mbio format 261) and contain processed swath bathymetry and acoustic backscatter data. The files were generated as part of the projects called Finding hydrothermal chimneys along the southern East Pacific Rise with machine learning approaches to AUV-based sonar data; and, Are Low-Temperature Hydrothermal Vents an Important but Overlooked Source of Stabilized Dissolved Iron to the Ocean? Funding was provided through NSF grants OCE20-06265, OCE17-55571, and OCE17-56402.
