As global temperatures begin to warm, ice sheets and glaciers at either pole begin to melt, this melt water has dire effects to our ocean currents! First of all, water movement occurs in all our oceans and is key to our oceans success. This movement is driven by many factors such as wind and the Coriolis Effect, the major contributor to deep water movement is thermohaline circulation. Thermohaline circulation depends on the temperature and the salinity of the sea water; together these two variables dictate the density of sea water in a given location. More saline, cooler sea water is more compact, hence the water is more dense and will sink to the bottom below the warmer less saline sea water which will rise to the surface. Temperatures and
