  "id": "MLC-T-ENV-016564",
  "term": "Marine Oceanic Mesopelagic Layer",
  "field": "Environment",
  "definition": "The region where light is vertically attenuated to below the level required for photosynthesis, generally between 200 meters and 1,000 meters in depth. Oxygen declines rapidly to a minimum, corresponding with the lower limit of the Mesopelagic Zone - due to high bacterial respiration from settling organic material.",
