It is
suggested that this feature is due to
|
topographic
steering by the abyssal layer
|
flow,
which is forced to follow the f/h
|
contours
of the bottom topography.
|
|
|
To
see if this is in fact true, we examine
|
twin
non-linear simulations, one
|
including
the bottom topography (figure
|
6a,
shown here), the other flat bottom
|
(figure 6b).
|
|
|
Results
indicate that the ridge feature, and
|
enhanced
transport, is absent in the flat
|
bottomed
simulation, providing firm
|
evidence
that the enhanced NHRC
|
transport
is due to topographic steering
|
by
the lowest layer flow.
