Fig. 19.7 Remote-sensing and aerial images of the Three Creeks
area, Andros Island. ( a ) Image illustrating the nearshore marine,
channeled belt, and inland marsh located, within a broad embay-
ment in the Andros coastline. ( b ) Ikonos image of part of the chan-
neled belt. Note the different geomorphic elements, including
well-developed creeks and fl anking levees, marshes and ponds. One
spillover lobe (cf. Fig. 19.5i ) is circled. ( c ) A small delta, extending
into an open pond (to the north). ( d - e ) Paired historical (1943) and
recent (2001) remote sensing image from the southern part of the
Three Creeks area, illustrating some changes. Note the contraction
of the marshes ( dark areas ) and the expansion of ponds (Remote
sensing images ( b ), ( c ), and ( e ) copyright GeoEye)
migration is evident in historical changes (Rankey and
Morgan 2002 ) or cores (e.g., Shinn 1986 showed only
~75 m migration) (cf. Wright 1984 ) .
The most infl uential processes impacting the geo-
morphology of the channeled belt are driven by water
and sediment transport through the creeks and into
adjacent environments. Most sediment on the tidal fl ats
is transported from the nearshore marine areas via
these conduits, probably associated with meteorological
events that suspend and transport offshore mud into
the channeled belt (Shinn et al. 1969 ; Ginsburg and
Hardie 1975 ; Hardie 1977 , cf. Rankey et al. 2004 ) .
Because sediment is transported from the ocean land-
ward through creeks, Shinn et al. ( 1969 ) described the
tidal fl at system as a delta “turned inside out.” The
same is true more literally at a fi ner scale, as illustrated
