  "field": "Meteorology and atmospheric science",
  "definition": "A calibrated transparent overlay, marked with lines representing temperature and depth, used to interpret the smoked-glass slide record from a mechanical bathythermograph. This grid allows for the visual conversion of the stylus trace into a quantitative profile of ocean temperature versus depth. It is placed over the smoked-glass slide to read the recorded data points.",
