Ocean velocity profiles were collected using an ADCP (300 kHz Teledyne RD Instruments Workhorse Sentinel ADCP) mounted on the CTD-Rosette during the Maria S. Merian cruise MSM107. During CTD-Rosette casts, the Lowered Acoustic Doppler Current Profiler (LADCP) collected full-depth profiles of velocities and echo intensity under the CTD frame over a 110.17 m profile with 27 bins of 4 m. The short profiles were combined into a record of full-depth absolute (i.e. in the Earth's frame of reference) velocities using the LDEO Software provided by A.M. Thurnherr (https://www.ldeo.columbia.edu/~ant/LADCP.html) and the CTD data (to know the vertical velocity of the LADCP frame and accurately calculate sound velocity throughout the water column), the ship position (to correct for horizontal movements) and the data from a ship mounted ADCP (to better constrain LADCP data close to the surface). A total of 16 profiles were collected. The processed ADCP data show the water velocity magnitude and direction over the whole water column every 4 m.
