Super earths are likely have a slightly wider habitable zone around their star, white or surface too. A planet twice the mass of earth, but the same density is only 26 % wider and 26 % stronger surface gravity. The average ocean depth on s f i a 26 has a pressure down there of 370 atmospheres. On an Earth-like planet you need to add an atmosphere of up to ten meters deep in the water to drop it below sea level. We guess earth had its own proto atmosphere blown off when moon formed and recollected from comet bombardments later on. If a planet could assume this basic over simplified approximation we started withEarth's total mass and 58 % more land cover than
