     373Experiment name: rotstr1_1310a, rotapex2_1310b, rotstr1_1310c, rotapex2_1310d. File names: rotstr1_1310a, rotapex2_1310b, rotstr1_1310c, rotapex2_1310d.
     374
     375Four experiments were conducted. For the first two experiments the tank was rotated with a rate of 0.041 rad/s (0.4 rpm) in the clockwise direction, which corresponds to a Rossby number of -2.
     376
     377rotstr1_1310a: The total experiment time was 36 mins. Inflow rate started with 10.61 L/s and then was decreased to 5.89 L/s until it reached a constant level. PIV measurements were conducted. Density excess and temperature were 20.5 kg/m^3^ and 23°C, respectively. ADV data were collected at the straight section (Position X1 - 75% down straight section, 56 cm upstream from the end of the straight section) from 15 to 25 min after the flow rate became constant. 7 sets of siphon samples were collected at 5, 10, 15, 20, 25, 30, and 35 minutes after the start of the experiment, with duration of 1 minute. The cross stream UVP collected data from 5 to 15 minutes, and the down-stream UVP collected data from 25 to 35 minutes.
     378
     379rotapex2_1310b: The total experiment was 30 minutes. Temperature and density excess were 22.5°C and 20.5 kg/m^3^, respectively. Inflow rate started with 10.69 L/s and then was decreased to 5.81 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).
     380
     381For the second two experiments the tank was rotated with a rate of 0.021 rad/s (0.2 rpm) in the clockwise direction, which corresponds to a Rossby number of -4.
     382
     383rotstr1_1310c: The total experiment time was 36 mins. Inflow rate started with 10.97 L/s and then was decreased to 5.78 L/s until it reached a constant level. PIV measurements were conducted. Density excess and temperature were 19.7 kg/m^3^ and 22.4°C, respectively. ADV data were collected at the straight section (Position X1 - 75% down straight section, 56 cm upstream from the end of the straight section) from 15 to 25 min after the flow rate became constant. 7 sets of siphon samples were collected at 5, 10, 15, 20, 25, 30, and 35 minutes after the start of the experiment, with duration of 1 minute. The cross stream UVP collected data from 5 to 15 minutes, and the down-stream UVP collected data from 25 to 35 minutes.
     384
     385rotapex2_1310d: The total experiment was 30 minutes. Temperature and density excess were 22.6°C and 19.6 kg/m^3^, respectively. Inflow rate started with 10.72 L/s and then was decreased to 5.78 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).
