The float was launched in a triad with NPS#20 and NPS#23 (these floats were "fast sinkers", they sank immediately and terminated its subsurface mission when the ambient mission exceeded a preset allowable value (Garfield et al., 1999)).
The float entered the undercurrent immediately after launching. At about Pt. Saint George the float stalled, then turned offshore and moved westward. (Figure 1, Figure 2). On June 30, 1994 the float was entrained by an anticyclonic eddy (Figure 4) with diameter of 54 km and period of 12 days

and remained there for about two months. After it was ejected from the eddy, it turned onshore and then made a large cyclonic curve to the northwest Figure 2.The float was ballasted for 275 dbar but settled deep, about 420 dbar. Initially it acted as a "slow sinker" and underwent a minimal sinking of 0.02 dbar/day, or 1.2 during 58 days in the undercurrent. Two days before the end of its scheduled 203-day mission the float sank abruptly and terminated its subsurface mission when the ambient mission exceeded a preset allowable value (Figure 3) (Garfield et al., 1999)
