This work was funded by the National Science Foundation (04241333 and 0728375). Ray Kreth and Mike Neeley-Brown have done most of the construction, testing, calibration, and preparation of the χpods as well as maintenance of Chameleon. We are grateful to the TAO Project Office for continued support in deployment and recovery of χpods on TAO moorings. The EQUIX mooring was deployed by the Applied Physics Lab at the University of Washington (R.-C. Lien, M. C. Gregg), and all χpods were skillfully and safely recovered by Jim Johnson (APL) and Daryl Swensen (OSU). Current speeds used for χT computations were provided by APL and NOAA.
