Calculation of Across-shelf-break Flux
Define the shelf-break section along the 1000 m isobath in the
model. Include across-shelf sections at either end to close the box.
At every point, calculate the gradient of bathymetry. Get the
component of vertically integrated flow in that direction.
Calculate the curvature, and the change of curvature, along the
shelf-break section.
Calculate the lagged correlation of onshelf transport and shelf-break
Onshelf transport is correlated (r=.45) with curvature
with a lag of 7.5 to 12.5 km.
“Water flows on the shelf when the bottom turns in front of it”.
