    274 The tank was rotated with a rate of 0.041 rad/s (0.4 rpm) in the counter-clockwise direction, which corresponds to a Rossby number of +2. Two experiments were conducted.
    275 
    276 Experiment name: rotstr1_1010a and rotapex2_1010b. File names: rotstr1_1010a, rotapex2_1010b.

     274Experiment name: rotstr1_1010a, rotapex2_1010b, rotstr1_1010c, rotapex2_1010d. File names: rotstr1_1010a, rotapex2_1010b, rotstr1_1010c, rotapex2_1010d.

     276Four 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 counter-clockwise direction, which corresponds to a Rossby number of +2.
     277
     278rotstr1_1010a: The total experiment time was 36 mins. Inflow rate started with 10.86 L/s and then was decreased to 5.92 L/s until it reached a constant level. The water was dirty so no PIV measurements were conducted. Density excess and temperature were 19.7 kg/m^3^ and 23.3°C, respectively. ADV data was collected at the straight section (Position X1 - 75% down straight section, 58 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. Cross stream UVP collected data from 5 to 15 minutes and down-stream UVP collected data from 25 to 35 minutes.
     279
     280rotapex2_1010b: The total experiment was 30 minutes. Temperature and density excess were 23.8°C and 20.4 kg/m^3^, respectively. Inflow rate started with 10.86 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).
     281
     282For the second two experiments the tank was rotated with a rate of 0.021 rad/s (0.2 rpm) in the counter-clockwise direction, which corresponds to a Rossby number of +4.
     283
     284rotstr1_1010c: The total experiment time was 36 mins. Inflow rate started with 10.86 L/s and then was decreased to 5.75 L/s until it reached a constant level. The water was dirty so no PIV measurements were conducted. Density excess and temperature were 20.2 kg/m^3^ and 24.3°C, respectively. ADV data was collected at the straight section (Position X1 - 75% down straight section, 58 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. Cross stream UVP collected data from 5 to 15 minutes and down-stream UVP collected data from 25 to 35 minutes.
     285
     286rotapex2_1010d: The total experiment was 30 minutes. Temperature and density excess were 24.1°C and 19.4 kg/m^3^, respectively. Inflow rate started with 10.89 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).
