Abstract : On a recent cruise aboard Oregon State University's R. V. Yaquina, Aanderaa current meters were lowered along with a Geodyne CTD to determine whether the calibration of the Aanderaa conductivity cell was pressure dependent. Two current meters, 268 and 755, were selected from a group of twenty and tested in this manner. Current meter 268 showed no evidence of any air space between the conductivity cell and its glass liner. Current meter 755 showed air space over about 60 percent of the area behind the glass liner. These current meters were selected because we expected cells with less air space to show less conductivity change under pressure, and cells with more space to change more. (Author)
