ITP Goes Sledding

WHOI research associate Rick Krishfield and engineering assistant Kris Newhall take part of an ice-tethered profiler (ITP) for a sled ride between a warehouse—where they tested and prepped it—and outdoor storage at the airport in Resolute Bay, Canada. A key element of WHOI’s contribution to a multi-institutional Arctic observing network is the ITP, which was developed by Krishfield and WHOI oceanographer John Toole. The ITP climbs up and down a mooring string, detecting the temperature, salinity, and oxygen content at various points in the water. (Photo by Chris Linder, Woods Hole Oceanographic Institution)
