| 278 | rotstr1_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. |

| 280 | rotapex2_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). |

| 282 | For 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 | |
| 284 | rotstr1_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. |

| 286 | rotapex2_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). |
