This work presents the results of the measurements of absolute gravity value g obtained over four field seasons in 2010-2013 at marine expeditionary station of Pacific Oceanological Institute at Shults Cape of Gamov peninsular (42.58 N, 131.15 E, Russia). The measurements revealed that during the first year the absolute g at the measurement point increased by 5.1 μGal, and during the second year, by 3.2 μGal. The auxiliary point No. 2 located 46 m below the main point No. 1 was founded in 2012 to create a gravimetric test site for calibration of the tidal gravimeter g-Phone
