    389 Density of the previous siphon samples were measured and recorded. Two experiments were conducted in which the tank was rotated with a rate of 0.0104 rad/s (0.1 rpm) in the clockwise direction, which corresponds to a Rossby number of -8.

     389Density of the previous siphon samples were measured and recorded. Also 3 guests were at Coriolis to visit the site and see the experiments. Two experiments were conducted in which the tank was rotated with a rate of 0.0104 rad/s (0.1 rpm) in the clockwise direction, which corresponds to a Rossby number of -8.

     393rotstr1_1410a: The total experiment time was 36 mins. Inflow rate started with 10.36 L/s and then was decreased to 5.75 L/s until it reached a constant level. PIV measurements were also conducted. Density excess and temperature were 20.5 kg/m^3^ and 22.3°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.

     395rotapex2_1410b:The total experiment was 30 minutes. Temperature and density excess were 22.4°C and 20.1 kg/m^3^, respectively. Inflow rate started with 10.58 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).

    407 When measuring the density of the siphon samples for this experiment it was revealed that the ambient was too salty so no experiments commenced and the tank was drained.

    410 The tank was drained, washed and cleaned. Then it was filled and rotated with 0.041 rad/s (0.4 rpm) corresponding to Rossby number of +2. Wiki notes were prepared and the website was updated. All files on the LEGI network were also updated.

     405When measuring the density of the siphon samples for this experiment it was revealed that the ambient was too salty in the current experiment and the one conducted on Friday. Therefore, no experiments commenced and the tank was drained immediately. Furthermore, Wiki notes were prepared and the website was updated. All files on the LEGI network were also updated.
