SADCP measurements in the Bransfield Strait in 2017
The kinematic structure of currents in the Bransfield Strait was measured over 50 transects across the strait using a Shipborne Acoustic Current Doppler Profiler (SADCP) onboard the R/V "Akademik Sergey Vavilov" (ASV) and "Akademik Ioffe" (AI) in 2017. The sections crossed all th...
