Ice Tethered Profiler observations: Vertical profiles of temperature, salinity, oxygen, and ocean velocity from an Ice Tethered Profiler buoy system

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 08:19 AM | Dataset Last Updated: June 06, 2026 at 12:00 AM
This collection contains repeated vertical profiles of ocean temperature and salinity versus pressure, as well as oxygen and velocity for some instruments. Data were collected between about 7 and 750m of the Arctic Ocean by Ice Tethered Profilers, including Ice-Tethered Profilers (ITPs) and Tethered Ocean Profiler (TOPs), that crawled up and down a conducting wire suspended from a buoy frozen into the ice pack. The profiles were collected roughly twice a day, depending on ITP programming, over the course of months to years. The vertical resolution of the final processed data is 1m, with horizontal resolution depending on ice drift speeds. ITPs have been released in different parts of the Arctic Ocean including near the North Pole and are intended to cover the whole Arctic ocean with depths exceeding 750m.
