Table 4 Results of GLM models for absent or small quantity of bio-fouling (F = 0), and different values of water turbidity (T). Chla_1mo = Chlorophyll-a concentration recorded by satellite one month before actual data; SST_sat = sea surface temperature recorded by satellite; solar_irr = solar irradiance; corr = sign of the correlation; neg = negative.
