This quantity names a “fingering” process between regions with differing values of this quantity (-5[1])that paradoxically leads to more (15[1])efficient mixing. Silver nitrate is used to measure this quantity in the Mohr–Knudsen titration. A polynomial function of a ratio of conductivities defines this quantity in the PSS-78, which is also determined by measuring conductivity in a CTD. Melting Arctic sea ice has led to the (*) slowing of the AMOC due to a decrease in this quantity. A type of circulation named for temperature and this quantity is also called (10[1])the global conveyor (10[1])belt, (-5[1])since temperature and this quantity determine the density of water. For seawater, this quantity usually equals about 35 parts per thousand. For (10[1])10 points, identify this quantity which measures the concentration of compounds such as sodium chloride in the ocean. ■END■
