I can only list a few regular «goings on'that I KNOW affect sea level; I'm certain that there are others: Change in overall temperature of the

oceans, marine life and its products building up the
ocean floors, melting land ice, undersea discharges of a variety of «stuff» from literally hundreds of thousands of sources, often at temperatures in the 1 - 2 thousand degree range, which we are only now beginning to notice, wind carrying dust from the land and
dropping it on the
ocean.
