Ice Tethered Profiler
Autonomous time-series profiler that measures conductivity, temperature and depth under sea ice, with near-real-time inductive telemetry.
Description
The Ice Tethered Profiler (ITP) is an autonomous time-series instrument that vertically profiles the water column under the ice, collecting in situ conductivity, temperature and depth measurements. Data can be transmitted in near real time via inductive modem when connected to a surface controller. Profiling depth, intervals and pressure stops are user-defined. Over 90 ITPs have been deployed in the Woods Hole Oceanographic Institution (WHOI) Arctic program since 2005.
Key features
- Depth: 30 m to 1000 m (mooring dependent)
- Minimum water temp: -2°C water (non freezing)
- Profiling speed: 25cm/sec (10cm/sec, 33cm/sec options available)
- Battery: 240Ah or 360Ah lithium battery pack
- Telemetry: Seabird Inductive Modem
Applications
- Arctic and under-ice water column measurements
- Long-term polar ocean observing programs
