Snorkel vs autonomous underwater vehicle surveys

Benthic photo transects implemented using an autonomous underwater vehicle (AUV) have the following advantages compared to a snorkel or dive survey:

  • More photos, straighter transects
  • More consistent: start/end point, speed, height
  • Increased data collection capacity
  • Can be used in deep water, unsafe or turbid water
  • Ability to program complex missions
  • No fatigue
