Satellite remote sensing reveals a positive impact of living oyster reefs on microalgal biofilm development [PDF]

open access: yes, 2018
Satellite remote sensing (RS) is routinely used for the large-scale monitoring of microphytobenthos (MPB) biomass in intertidal mudflats and has greatly improved our knowledge of MPB spatio-temporal variability and its potential drivers.
