It changes the distribution patterns of pelagic marine species So to answer the first part of your question, technically yes, but the surface is less dense by such a small amount that it can be considered a negligible difference. But if ocean currents are indeed becoming faster and shallower, there are many implications for the planet. a. This type of ocean circulation is called thermohaline circulation (therme=heat, halos=salt) because the vertical movement is caused by differences in temperature and salinity (the amount of salt in water).
