Two series of salinity measurement data

1- Five CTD sensors located in the Casamance estuary implemented gradually from 2014 to 2017

       The equipment is composed of Decagon CTD 10 sensors connected with Decagon Em50 data logger

2- Forty measurement points documented twice a year at the end of rainy season and at the end of dry season

       Salinity is measured with:

- a conductimeter Hanna 98129 for values less than 2 mS/cm

- a conductimeter Hanna 98130 for values between 2 to 20 mS/cm

- a refractometer PCE 0100 for values above 20 mS/cm
