The 14th data acquisition for PLP2021 took place on Wednesday 25/08/2021. A number of 4L containers had been replaced the previous day, effectively raising the mesh back to surface level. More containers were added before the passage of the Sentinel 2 satellite. Biofouling levels are steadily increasing. A small part of the mesh was partially cleaned from biofouling during the target maintenance. Very high resolution images were acquired using a DJI Phantom 4 pro RTK drone. No hyperspectral measurements were taken. Metadata collection included wind speed and direction, light intensity and turbidity using a Secchi disk empirical measurement. Conditions were optimal with low winds and a clear sky.
