“…One body of work that systematically studied the response characteristics of conductivity cells was performed in a salt-stratified tank, in which a sharp interface was maintained between two mixed layers by the turbulence generated by oscillating grids (Gregg et al, 1981(Gregg et al, , 1982Gregg and Hess, 1985). However, these tests failed to detect the substantial thermal mass problems of one conductivity cell (Lueck and Picklo, 1990;Lueck, 1990), since there was little or no temperature difference across the salt interface in most of the trials.…”
