Float was launched in a triad (NPS#90, 91 , 92 ~ 146 km off Monterey Bay approximately along CalCOFI Line65 with a distance between the points in a row of ~20 km. After the launching the float moved eastward and then north-northwest till January 12, 2002 when it turned to west into the interior (Figure 2). On January 24, 2002 it was trapped by an anticyclonic eddy (Figure 4, looper#1) with the following characteristics:
Number of loops 2.5 Diameter, km 108.8 Duration, days 69 Period, days 27.6 Swirl velocity, cm/s 14.3 Translation velocity, cm/s 2.2 Direction, degrees 320 Rossby number 0.03
While in the eddy, the float was moving northwest. The float was entrained back in the undercurrent north of Point Reyes on June 4, 2003 and moved there for more than 60 days. North of Cape Arago it curved to the west and then back to east in a cyclonic loop. It was then moving along the coast and became trapped in a submesoscale anticyclonic eddy (or two separate eddies) (Figure 4, looper#2):
Number of loops 30 Diameter, km 20.8 Duration, days 125 Period, days 4.2 Swirl velocity, cm/s 18.2 Translation velocity, cm/s 1.6 Direction, degrees 322 Rossby number 0.16
and remained there till the end of the mission.
Being balanced for 275 dbar, the float was rising and sinking between 264.5 and 344.8 dbar during the mission (Figure 3).
