422 | | The tank was washed and cleaned and both conductivity probes were calibrated. Some photos were taken from the position of the ADVs, UVPs and the siphon rig. The tank was then filled and one experiment was conducted where the tank was fixed which corresponds to a Rossby number of infinity. |

424 | | fixstr1_1810a: The main goal for this experiment was to collect PIV data and shot a high quality movie from above. The total experiment time was 12 mins. Inflow rate started with 11.11 L/s and then was decreased to 5.58 L/s until it reached a constant level. Density excess and temperature were 20.2 kg/m^3^ and 21.8°C, respectively. 2 sets of siphon samples were collected at 5 and 10 minutes after the start of the experiment each with duration of 1 minute. The the down-stream UVP also collected data for 10 minutes. The laser sheet was set to be 2 cm above the channel's bottom for shooting the movie. |

| 430 | rotapex2_1810b: The total experiment was 30 minutes. Temperature and density excess were 21.8°C and 20.2 kg/m^3^, respectively. Inflow rate started with 10.69 L/s and then was decreased to 5.83 L/s until it reached a constant level. ADV measurements were collected from 15 to 35 minutes after the start of the experiment at the second apex (Position X4). |
