ABOVE: Hypothetical sampling grids for time-series (1 & 2) and high-resolution (3) AUV paths. Location of the sampling grid will be determined, at least initially, by the location of the oceanographic front, but will remain near shore in the northern portion of the bay.

A. Time series

Sampling grids will be run by the AUV on alternating days of the first 5 to 6 days of deployment, with the goal of getting continuous data for at least 5 days.

ADCP information and concurrent water samples for phytoplankton, nutrients, and chlorophyll will be obtained and prepared by the scientists on the R/V Pt. Sur, with stations at 1 km resolution along the transect lines..

Verical bathyphotometer profiles, absorption and scattering, "SPLAT" screen video, and zooplankton samples will be obtained by the scientists on the Shana Rae.

The baseline of A may be relocated to lie on top of the baseline of B. This would provide a continuous time-series along 5km of the 10km line, but would provide fewer boundary conditions for the models.

B. High-resolution

The 1-km box pattern shown in C will be sampled at the highest possible resolution (100 meter separation between lines) twice during each of the high-res night samples, with concurrent profiling and sampling as above.

In addition, Edie Widder will use the ROV Ventana will perform horizontal video transects along lines in this region to compare and supplement the bathyphotometer data from above.

2. Personnel in the Field

• Steve Haddock, MBARI (Pt. Sur)
• Mark Moline, Cal Poly SLO
• Edie Widder, Harbor Branch
• Christy Herren, UC Santa Barbara
• Erika Heine, Cal Poly SLO
• Robert Harper, UC Santa Barbara
• Christina Blevins, UC Santa Barbara
• Amanda Briggs, UC Santa Barbara

We will be monitoring channel 79A on the VHF radio during night operations.
(Subject to change due to competing radio traffic.)

5. Directions to Santa Cruz Harbor to meet with the Shana Rae:

If the boat is on a westside dock, between A and F, come up Hwy
1 thru Aptos, past 41st Ave, and take the Soquel Ave exit (don't take
the Capitola/ Soquel exit B4 41st). Left on Soquel & over the freeway
you just got off, and left again at the 2nd light onto 7th Ave.
Down 7th toward the beach, thru the light at Capitola road, over the RR
tracks & past the Harbor Cafe, to a right onto Eaton at the light. Take
Eaton across the bridge over the harbor, to a left onto Seabright at the
light. Down Seabright toward the water, to another left onto Atlantic,
to another left at the top of the hill by Aldo's, down into the parking
lot where the docks go A,B....F. I could be on any of these WEST side
docks, but you'll know which by then.

If the boat is parked on an eastside dock, it'll be
something between L and T, and everything's the same up to the bridge
over the harbor. You take that right onto Eaton, from 7th, but before
going over the bridge, go left on Lakeside. Then an immediate right down
the hill into the parking lot, where the docks are lettered backward
from your point of view, T,S,.....L.
