subsidence
in
drained Histosol
Everglades, Florida
Subsidence in drained Histosols
of the Everglades is illustrated by the post in the center of the
photo. The post was installed in 1924, with the top of the post
at the land surface. This photo was taken ~1975 and it shows the
land surface approximately 4 feet below the top of the post. This
represents a subsidence rate of ~1 foot per 10 years. In contrast,
organic matter accumulation rates in Histosols are usually measured
in inches per 100 years.
