The acquisition of conductivity/salinity data alongside the SeaFETTM is recommended. The acquisition of temperature data is not necessary as the SeaFETTM performs temperature measurements. Typically, conductivity and temperature measurements are combined in standard sensor packages. One can use an external temperature measurement calibrated to a relevant scale to confirm the accuracy of the SeaFETTM temperature measurement.
The proximity of the two sensors, as well as, the abruptness of spatial gradients in temperature are both important considerations.
