During February 1986, a 0.5 km-wide by 2.0 km-long region of spectacular bottom
topography was discovered off the west coast of the northernmost island of the
Tobacco Range mangrove group, Belize. This unusual marine landscape consisted
of vertical submarine peat exposures, tilted slumping blocks of fossil peat, and long
narrow fractures. The upper edges of the exposed vertical walls were composed of a
10 to 20 cm-thick veneer of a living Thalassia testudinum community atop a 1 to 7 m thick
consolidated layer of fossil mangrove peat. This seagrass-dominated peat
surface sloped westward to its point of lowest relief ( < 1.0 m, 500 m offshore) and
contained poorly sorted sandy gravels and gravelly carbonate sands (mostly mollusc
and foraminiferan fragments) on the unfractured surfaces and muddy calcareous
peat sediments within the fracture depressions. Florida Atlantic University.
