Processed multibeam bathymetry data from the southern Mid-Atlantic Ridge, 50.2°S-51.5°S (RR2301, 2023)

A bathymetric survey using a Kongsberg EM124 echosounder was done along the Mid-Atlantic Ridge and its flanks between 50.2 and 51.5°S during the February 2023 R/V Roger Revelle cruise RR2301 (Chief Scientist: Tamara Russell). Survey lines were acquired at a typical vessel speed of ~9 kt (~4.6 m/s), with tracks spaced ~12 km to provide almost 100% bathymetric coverage. Adverse sea conditions during data acquisition caused a considerable number of ping artifacts due to vessel motion, which were removed manually on shore using QPS Qimera software. The final bathymetric grid was constructed using MB-System software at 100 m x 100 m node spacing. The grid is in GMT-compatible netCDF format. The survey was performed using UC Ship Funds.
