The 20th data acquisition for PLP2022 took place on Thursday 29th of September. Ancillary data measurements including sea surface temperature, wind speed, light intensity, Secchi disk depth, dissolved oxygen, GPS position and buoy temperature were performed. UAS RGB, multispectral and thermal images were also acquired. No cleaning of the non-biofouled target was performed (30 days biofouling). The 5×15 PVC target’s inner “waffle” pattern on the southern side has been slightly deflated. Water samples were collected for chlorophyl concentration assessment for the Aquasafe project. Conditions were partly cloudy with low intensity winds and medium intensity gusts.
