In recent years, the volume of ice floating in the world's oceans has changed significantly. Some believe that these changes do not affect sea level, and floating ice loss has often been neglected in studies of sea level rise. However, because ice is fresher (less salty) than seawater, floating ice causes the ocean to become less dense as it melts, and so the ocean expands.
