AFAICT tidal heating is quite minor, and the main heat exchange is therefore at the surface: solar radiation, radiative loss and evaporation. (Rain and river influx is also negligable) | |

| Sep 12, 2011 at 13:03 | comment | added | MSalters | From what I found, yes. Of course it's not the only effect, but it's an interesting one as it affects both temperature and salinity. At tropical temperatures, heat loss through evaporation exceeds radiation. | |
| Sep 12, 2011 at 11:45 | comment | added | eudoxos | @MSalters: I worked with the data OP said are provided by the sensors. I wrote computed salinity was function of conductivity and temperature. Temperature is measured directly, the sensor name reveals that. (.. evaporation?!) | |
| Sep 12, 2011 at 10:07 | comment | added | MSalters | Salinity isn't a direct function of temperature, it's far more complex. It's been measured directly, though, just by dragging it up. Similarly, temperature is influenced by many factors (e.g. currents, evaporation) so it's often measured instead of calculated. | |
