GOBOP has been active in delayed-mode salinity calibration and quality control for core Argo floats since the start of the U.S. Argo program in 1999. Between May 2001 and June 2002, PMEL deployed 22 floats in the Bering Sea and North Pacific in support of Steller's Sea Lion climate studies. Starting in December 2003, PMEL began to deploy floats regularly as a contribution to the Argo program. PMEL Argo floats now comprise a substantial part of the international array.
