Description
From 9-17, September 2017 and from 9-14, October 2017 R/V surface drifters were deployed by scientists from the Naval Postgraduate School (NPS), the University of California, San Diego, Scripps Institution of Oceanography (SIO), and the University of Washington on the inner continental shelf (20-100 m isobaths) off the central coast of California between Oceano beach and Point Conception as part of the 2017 Inner Shelf Experiment (ISDE). Drifter activities were coordinated with several other ISDE observational efforts including 1) the large vessels R/V Sally Ride, R/V Oceanus and R/V Sproul, 2) the small vessels R/V Sally Anne, Sounder, Kalipi, and Sand Crab, 3) coastal radar provided by SIO and OSU, and 4) aircraft remote sensing provided by SIO and the University of Washington (UW). Drifter releases were designed to observe surface dispersion, vorticity, and divergence by wind driven currents, eddies and submesoscale structures, fronts, nonlinear internal waves, and topographic effects. In total, there were 13 separate 4 hr (approximately) releases of 20 (approximately) drifters resulting in over 250 separate drifter trajectories. Data contained herein includes GPS drifter positions, velocities, and for some drifters temperature 1 m below the surface.
