This is because the density change is dependent on the temperature (Thermo) and salinity (Haline). Salinity is defined as the measure of the concentration of dissolved inorganic salts. The average seawater density is 1.026g cm3 along with an average salinity of 34.77 practical salinity unit (p.s.u). The density of water is directly proportional to its salinity, meaning when the salinity of the water increases or decreases, so does its density. The Conveyor Belt begins when cold, saline heavy water that has lost its moisture at the North Atlantic Ocean near the pole sinks to the bottom of the ocean floor. This cold, saline water travels down towards the South pole between South America and Africa. When it reaches Antarctica, the water is recharged …show more content…

Other oceanographic instruments are equipped with global positioning technology while others are equipped with multiple technologies. All equipments that measure ocean currents through drifting are termed Lagrangian measurements. They were named after a mathematician called Joseph Louis Lagrange. He was the first to describe the path followed by fluids. Another way to measure ocean currents is by the use of Eulerian measurements. These equipments got their names from a Swiss mathematician called Leonhard Euler. These instruments measure the speed and direction of a current in a fixed point. The instrument is anchored in the ocean water and measures the water speed and direction as the water moves pass the instrument. The Eulerian method is becoming more commonly used simply because it is easier to retrieve these instruments rather than to locate a drifting object. Another method of measuring ocean currents is by the use of The Acoustic Doppler Current Profiler. The device is deployed on the sea floor or attached to the bottom of a boat. The device sends an acoustic signal through the water column that bounces off water particles. The instrument then calculates the direction and speed of the current by knowing the frequency, distance, and the time took for the signal to
