  "term": "Bathythermograph slide",
  "field": "Meteorology and atmospheric science",
  "definition": "A smoked glass slide used in older mechanical bathythermographs to record temperature and depth data. As the instrument descends, a stylus scratches a trace onto the smoked surface, creating a permanent record of the ocean's thermal profile. These slides are then analyzed to extract temperature-depth information.",
