Tropical Pacific Drifting Buoys
Rick Lumpkin / Mayra Pazos, AOML, Miami
During July 2017, 194 satellite-tracked surface drifting buoys were reporting
from the tropical Pacific. The drifter array did not reveal any large-scale
current anomalies in the basin. Staring with this report, velocity from
undrogued drifters is recovered as described in Laurindo et al. (2017),
Deep-Sea Res. 124, doi:10.1016/j.dsr.2017.04.009.

The linear segments of each trajectory represent a one week displacement.
Trajectories of buoys which have lost their subsurface drogues are gray; those with
drogues are blue.
