Abstract:

Current meter moorings with internally-recording instruments were deployed on cruise (G01) in July 2012. The moorings were recovered and redeployed in July 2013 and recovered in July 2014. During this cruise a CTD/Rosette samplers, two shipboard acoustic Doppler currents profilers (75Khz and 300Khz), and an underway continuous sampling system were operated. This data set include CTD data, NISKIN bottle samples (salinity, dissolved oxygen and nutrients).
