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 curvature.

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”.
