The float was launched in a triad with NPS#64 and NPS#62 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.

The float was entrained in the undercurrent immediately after launch and moved alongshore for about two months (Figure 1). On June 22, 1998 the float entered an eddy that broke away from the undercurrent. For the rest of the mission the float moved in an interior flow.

The float was ballasted for 275 dbar but the real pressure was more or less steady at ~350 dbar for the first half of the mission. Starting from December 1998 the float steady dropped to ~385 dbar (Figure 3 ).
