Principle of Measurement

The FIELAX heatflow measuring system records temperature as a function of time. The temperatures are recorded with 22 thermistors that are placed within a sensor string. The sensor string also contains a heating wire with which a distinct amount of energy is released into the sediments.

  • A: lowering to seabed
  • B: penetrating into seabed
  • C: measuring thermal decay of frictional heat
  • D: heat pulse
  • E: measuring thermal decay of heat pulse
  • F: pullout and retrieve to surface
