2020 Roger Revelle SAT EM712 and EM124

Cruise ID: RR2002
Multibeam System: EM712/EM124
Dates: October 18-25, 2020

The R/V Roger Revelle (RR) underwent a major mid-life refit / repower during 2018-2020, receiving new
engines and a new gondola to reduce bubble sweep along the acoustic transducers. The Revelle’s multibeam mapping systems were fully upgraded to Kongsberg Maritime EM124 and EM712
multibeam echosounders with a Seapath 330+ position/attitude system and MRU 5+; a new Kongsberg K-Sync unit was installed to manage synchronization of these and other acoustic systems (e.g., full Simrad EK80 suite).
