"The Volkihar vampires of eastern Skyrim live under haunted, frozen lakes and only leave their dens to feed. They have the power to freeze their victims with icy breath, and can reach through the ice of their frozen lake dens without breaking the ice. The Vampires featured in the Elder Scrolls:Skyrim game do not possess or at least display the ability to reach through the ice, in fact the Vampires of skyrim are very similar to the Oblivion Vampires, the only differences being the appearance of the vampire and they are only weakened by the sun and not burned by it, other differences are the powers though a few of the oblivion Vampire powers remain."
I just found this from the wiki
