ABSTRACT: The equations for gradient of electric field in seawater induced by
gradients of salinity, temperature and pressure were developed by means of
non-equilibrium thermodynamics. Extrathermodynamic assumptions and accepted
chemical model of seawater permit to carry out numerical calculations of electric
field caused by diffusion, thermodiffusion and barodiffusion for realistic
hydrophysical structure of the ocean. It is shown that contribution of
barodiffusion into electric field of the ocean is almost constant (about -3 × 10-7 V/M). This magnitude can be ignored in many cases because it is too small.
However natural salinity and temperature gradients significantly impact into
electric field of the ocean.
