The float was launching in a triad together with NPS#70 (unsuccessful mission) and NPS#71 (Figure 1). The triad was launched in an across-shore slightly curved arc with the nearest to the shore point about 270 km distant from P. San Lois, and distance between points in the row of about 10 km.

After the launch the float moved northward and on August 1, 1999 turned offshore west of San Francisco (Figure 2). While moving westward the float made two consecuent anticyclonic loops (Figure 4):

The float surfaced about 200 km from the launching point.

The float was ballasted 275 dbar but the real depth reached by the float was initially 611.0 ± 3.7 dbar. After the float entered the eddy it started to sank and dropped to 793.1 dbar on April 13, 2000 (Figure 3).
