Digging hole #1, Aug 18
Hole #1 snapshot, see astericks, Aug 18
Hole #1, Aug 18, immediately after dig. Timex image
Removed sand
Cool megaripple features
Hole #1, Aug 18, immediately after dig. Variance image
Hole #1, Aug 18, day after dig. Brightest image
Hole?
Walking surfer(1/2 second captures)Highest swash
Two days after, daytimex image
Hole plus instrument pipes
Fourier Phase Maps – astericks marks Elgar hole
Hole #2, Aug 20
Time stamps on all images
Hole #2 Variance
(partially cloudy day, so beach also shows up).
Hole #2
Dye Experiment
Snapshot goes with next slide. Notes waves from southeast.
Simultaneous timex. Note piling wakes from longshore current
Waves from southeast. Elgar group about to “jet”
Nice swell propagating over very shallow bar then creating undular bore upon entering the trough

Rectification of Same Brightest Images
Rip heads
Long SE swell crossing short NE wind waves
Striped dissipation patterns due to long/short wave interaction
Sept 9, 2010 merged rectification.(bar less defined at 800m and near pier)
26 August rectification(messy trough)
Nice SE Swell from Hurricane Danielle
Argus Resolution Map
Pixel Array Design, Including VBar
Vbar Stack Results
V convergence forces rip
V divergence over shoal
Southerly current
