In the 2005/06 Antarctic field season, a Sea-Bird SBE37SM-RS232 conductivity-temperature-depth (CTD) recorder was deployed through a hot-water-drill hole approximately 1-3 km from the ice shelf front. The sensor was placed about midway in the water column below the ice shelf, with a cabled connection for data transfer and power supply to the surface.
