El caracter de Eros es afin al de la belleza, pues ambos son mediadores necesarios (Secchi 60) y ninguno es la meta; son los recursos para dialogar con la naturaleza sensible del hombre.
The environmental parameters measured in situ for the period 2009-2015, salinity, Secchi (water clarity), and temperature, did not exhibit a significant correlation with any of the seagrass measurements (Table 4).
A lake can vary in water transparency, so it is important to take numerous Secchi disk readings throughout the day.

First, Secchi disks are used to measure the maximum water depth at which an object may be observed from the surface.
pH (7.6-7.8), ammonia (NH4-N) and `nitrites (NO2-N) less than (0.001mg/l), Secchi's disc visibility (8 cm to 46 cm).
Killer whales, on the other hand, have been reported in southern Brazil throughout the year, usually near the shelf break and the continental slope, in waters depth ranging from 110 to 3500 m (Castello and Pinedo, 1986; Pinedo et al., 2002; Dalla Rosa and Secchi, 2007; Passadore et al., 2015; Di Tullio et al., 2016).
The turbidity levels are determined by the Secchi disk depth (The Secchi disk depth provides a method for assessing turbidity.
