Advanced Multi-Penetration Heat Flow Probe (ADHFP)
The Advanced Multi-Penetration Heat Flow Probe (ADHFP) is currently under development by a team centered at the CMTD facility and led by Dr. Robert Harris. The ADHFP is a joint project between Oregon State University, University of California Santa Cruz, and Woods Hole Oceanographic Institution. Initial testing is scheduled for June of 2022 aboard RV Sally Ride.
The system will consist of a weight stand, a strength member, an electronics package, and an option for either a 3.5- or 6-m oil-filled thermistor tube. The probe will measure heat flux in seafloor sediment. It will make multiple penetrations over a single 48-hour submersion operating in depths up to 6,000 meters.
Select data will be transmitted to the surface via an Ultra-Short Baseline (USBL) system that will also precisely locate heat flow determinations. The full data package will be stored in the onboard data logger for retrieval upon probe recovery.
