The float was launched in a triad with NPS#64 and NPS#65 along the coast approximately above the 1500-m isobath (Figure 2), about 40 km off the shore between 34.5° and 36°N. The distances between the points were ~ 70 and 130 km.

After launch the float demonstrated marginal reversing flow for the first 26 days. On May 24, 1998 the float turned inshore and entered the California Undercurrent. For the next 70 days the float was moving alongshore. On August 5, 1998 it curved offshore and then seems to enter an eddy: it curved first anticyclonically, then cyclonically and then moved westward. In the end of the mission the float was moving southeastward (Figure 1).

The float was ballasted for 275 dbar but the real pressure was 375.7 ± 28.5 dbar (Figure 3 ).
