Water velocity profiles were gathered in the Bay of Sept-Îles from the 16th to the 18th of May, 2018, as part of the Canadian Healthy Oceans Network (CHONe II) program. Current profiles were collected using a Teledyne RDI Sentinel V 500 kHz ADCP fixed on a Biosonics BioFin aluminum towing body and towed at a speed of approximately 2 m s−1. The ping frequency and vertical resolution were set to 0.5 Hz and 0.5 m yielding a 50 m depth range. The mean depth of the towing body was 0.9 m and the centre of the first bin was 2.6 m deep. Towed ADCP velocities were smoothed with a 63 ping horizontal moving average and gridded at a resolution approximately equivalent to the distance travelled by the boat in the corresponding time (252 m). Water velocity data were collected inside the bay during flood tide. Repeated passages were also conducted at the mouth of the bay, between the port of Sept-Îles and Pointe à la Marmite during one semidiurnal tide cycle (12 h). ...
