Sedimentation rates. Field measurements of sedimentation between December 2014 and March 2017 indicated a mean rate of 0.048 ± 0.013 SE m yr-1 on the restored site. As these sampling points were only located in a small portion of the site, comparison of successive DTMs were used to assess sedimentation across the site.

After dropping blood (approximately 0.2 mL) into the pipette tip, the blood flow can be started and stopped by periodically operating a pinch valve. To evaluate variations in RBC aggregation due to the continuous ESR, an EAI (Erythrocyte-sedimentation-rate Aggregation Index) is newly suggested, which uses temporal variations of image intensity.
