Fig. 10.8 Plots showing the
morphometric analyses and
current data from the Grand
Bahama Bank study area.
a Mound footprint area
versus mound footprint
shape. Mound shape is based
on the principal axis ratio
(PAR, y-axis): values
approaching one indicate
circular shapes, whereas
values approaching zero
represent elongated forms.
Graph shows that mounds do
not become elongated as their
size increases. b Mound
footprint orientation based on
the azimuth of the principal
axis (black arrow) of every
mound analyzed. Graph
shows that mounds do not
have a preferential footprint
orientation. c North–south
current velocity component
versus elapsed AUV survey
time (x-axis). The current
reverses approximately every
six hours, indicating tidal
bottom current regime
