The Ice Tethered Profiler (ITP) vertically travels along a fixed mooring wire at 25cm/sec and is suited for (but not limited to) sampling the water column under the ice, collecting data in lakes and shelves, and performing studies in coastal oceans. The anodized aluminum housing is narrow for deployment through a bore-hole. The ITP transmits near real-time via inductive modem when connected to a customer-supplied surface controller.

• Depth range: 30m-1000m (open ocean or lake), 5m-1000m (ice floe).
• Minimum Temperature: -2° C (non freezing).
• Available sensors: CTD, dissolved oxygen data, PAR, optical backscatter (other sensors can be integrated).
• Options: 360Ah battery for 50% more battery capacity, motors of 10 or 33cm/sec, mooring stoppers for the top and bottom profile limits.
