THE "SOLUTION PLANE" RECTILINEAR GRID IS DEFINED TO APPROXIMATE 

 THE TEMPERATURE/DEPTH SCALE OF THE STANDARD CURVELINEAR GRID 

 BATHYTHERMOGRAPH. THE BT PROFILE (INSET) WAS VISUALLY DIGITIZED 

 AT FIVE METER OR FIFTEEN FOOT INTERVALS. DATA POINTS (DOTS) ARE 

 PLOHED ON THE SOLUTION PLANE. "REGRESSION POINTS" (ASTERISKS) 

 WERE CALCULATED USING THE THREE LEVEL TOLERANCE ALGORITHM 

 DESCRIBED IN THIS REPORT.
