| Summary: | <p><strong>Series 2: CO2 Aggregation Experiment - Aggregate Sinking Velocity</strong></p> <p>The sinking velocities of ten randomly selected aggregates from each tank were measured<br /> in a 2-liter cylindrical settling column that was 8 cm wide in a temperature constant room . Each<br /> aggregate was allowed to sink out of the wide bore pipette into the settling column. The duration<br /> of the descent of the aggregate over a distance of 20 cm, from 6 cm below the surface to 6 cm<br /> above the bottom, was monitored using a stop watch. Just before this, the length and width of<br /> each aggregate were measured to the nearest mm under a dissecting scope. Aggregate volume<br /> was calculated based on an ellipsoid shape, assuming that width and depth were identical.</p> <p><strong>Reference:</strong> Passow, U., Rocha, C.L.D.L., Fairfield, C., Schmidt, K., 2014.
