This quantity names a “fingering” process between regions with differing values of this quantity that paradoxically leads to more 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 (-5[1])to the (*) slowing of the (-5[1])AMOC due to a decrease in this quantity. (10[2])A type of circulation (10[1])named for temperature (10[1])and this quantity (10[1]-5[1])is also called the global conveyor belt, since temperature and this quantity determine the density of water. For seawater, this quantity usually equals about 35 parts per thousand. For 10 points, identify this quantity which measures the concentration of compounds (10[1])such as sodium chloride in the ocean. ■END■ (10[2])
