The engineering design work for the ITP was initiated by the Cecil H. and Ida M. Green Technology Innovation Program (an internal program at the Woods Hole Oceanographic Institution). Prototype development and construction were funded jointly by the U.S. National Science Foundation (NSF) Oceanographic Technology and Interdisciplinary Coordination Program and Office of Polar Programs (OPP) under Award OCE-0324233. Continued support has been provided by the OPP Arctic Sciences Section under Award ARC-0519899 and internal WHOI funding. Numerous WHOI engineers and technicians contributed to the ITP development and design, including Ken Doherty, Dan Frye, Terry Hammar, John Kemp, Don Peters, and Keith von der Heydt. We also acknowledge the technical assistance provided by McLane Research Laboratories, Inc., Sea-Bird Electronics, Inc., and Webb Research Corporation during the ITP development effort. We thank the officers and crew of the CCGS Louis S. St-Laurent and members of the science parties for their assistance in deploying the prototype instruments, as well as Eddy Carmack, Fiona McLaughlin, Sarah Zimmermann, and Koji Shimada for including our ITP activities in the collaborative Beaufort Gyre field program. Thanks also are given to Leif Thomas and Bob Pickart for valuable discussions.
