2. Map of moorings for HB Phase III investigation (funded by OCSD)
Looking at data from mid-June to mid-Oct 2001, used moorings 3,5,6,7 (in a line offshore) top bins from all ADCPs, which range from 3-4 m
3 and 5 are 1 m bins, 6 and 7 are 2 m bins
Also used all bins from M5 to get an idea of horizontal and vertical variability, wind from M7 and ASOS from LBH and JWA
Not included here are LBH (up coast) and JWA (inland slightly west)

3. Plot of sea level height at LA basin (slightly north), this and a tidal analysis show the tide is predominantly semidiurnal for this area

4. CW – red CCW – green Total – blue Spectral Units: (cm2/s2)/cph
Plot of rotary spectra for all top bins, point out colors of lines, units, scales
Diurnal peak at 24 hours and sd peak at hours (S1 and M2)
