Abstract
The paper presents a determination method for the field data conversion coefficient of the laser-interferential instruments developed on the basis of equal-arm and unequal-arm Michelson interferometers, into the values of hydrospheric pressure variations during the sea wave registration. Based on a comparison of experimental data obtained in the bays of the Primorsky Territory in various wave period ranges and at different depths, it is shown that there is a strong dependence of the dimension conversion coefficient on the depth of immersion.
