The ice-tethered profiler: \textsc{a}rgo of the \textsc{A}rctic

Abstract

Ice-Tethered Profilers (ITPs), first deployed in fall 2004, have significantly increased the number of high-quality upper-ocean water-property observations available from the central Arctic. This article reviews the instrument technology and provides a status report on performance, along with several examples of the science that ITPs and companion instrumentation support.
