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.
