Collaborative Research: Development of an Ice-Tethered Winch for the Seasonal Ice Zone
To help fill the data gap that exists in oceanic observations over the Arctic shelf, we have developed a new autonomous profiler, the Ice-Tethered Winch (ITW). The ice-tethered winch (ITW) combines the design of two established technologies, the Ice-Tethered Profiler (ITP) and Arctic Winch. Merging...

| Summary: | To help fill the data gap that exists in oceanic observations over the Arctic shelf, we have developed a new autonomous profiler, the Ice-Tethered Winch (ITW). The ice-tethered winch (ITW) combines the design of two established technologies, the Ice-Tethered Profiler (ITP) and Arctic Winch. Merging these technologies allows for expansion upon their individual capabilities by creating a new instrument that can both telemeter subsurface data from beneath the ice and profile the water column over variable depths. The ITW provides relatively high resolution (four profiles daily with sub-meter vertical resolution) time series of water-column physical and optical properties, including temperature, salinity, pressure, turbidity, and chlorophyll. The ITW can transition between an Eulerian platform when tethered to landfast ice and a semi-Lagrangian drifter when in open water. More information about the project and full data records can be found through the ITW and ITP websites, respectively (see related links). |
