NCEX: Array Plans for NCEX Field Experiments

Array Plans for NCEX Field Experiments

FIGURE 1: Overall NCEX Array Plan

The figure above shows preliminary array plans for observing waves and currents near, between, and onshore of the submarine canyons. The contours are depth below mean sea level in m. Numerical model simulations will be used to refine the array plan. Surfzone bathymetry will be measured using a GPS system and a sonar mounted on a waveruner.

FIGURE 2: Beach profile and the proposed NCEX instrument locations.

The research plan for NCEX swash studies will include measuring swash and surfzone velocities along a cross-shore transect (FIGURE 2) using 3 sets (separated horizontally) of 2 vertically-stacked small ADV current meters, as well as 5 other ADV current meters. Pressure sensors will be colocated at each instrument station.

FIGURE 3: NCEX Large Scale Video Plan	FIGURE 4: NCEX Rip Current Video Plan	FIGURES 3 & 4: Camera locations and their respective footprints are indicated by the purple dots and black lines, respectively. Depth contours are in 5 m increments from -100 to 50 m relative to mean sea level. Submarine contours are in blue, and sub-aerial contours in red.
The video plan for the large-scale array of cliff mounted video cameras (FIGURE 3) and the small-scale shore-based and balloon-mounted array deployed just onshore of Scripps Canyon (FIGURE 4). Wave breaking patterns and run-up excursions will be measured across the 5 km region. The tethered balloon-mounted camera will be located at number 10 (FIGURE 4).
