A cooperative study on a project to conduct a high-resolution seismic-reflection survey of the area
around several Comprehensive Everglades Restoration Program (CERP) projects was begun on
November 13 and continued on December 3.
Participants include Jack Kindinger, Chandra Dreher,
Dana Wiese, and Jim Flocks (St. Petersburg), Kevin Cunningham (WRD, Miami), and Cynthia Gerfvert
and Steve Kupa of the South Florida Water Management District (SFWMD).
The CERP projects are focused
on the surficial aquifer and ground-water flow through the area located in the eastern part of Everglades
National Park west of Miami. The objective of the survey is to image and map the limestone stratigraphy
of the subsurface to 60 m.
This is not the first time we have collected boomer data from a 16-ft Jon boat
(a flat-bottomed boat designed for shallow inland waterways), but it is our first attempt to acquire data
from canals dug in limestone. This cooperative study evolved from other successful cooperative studies
conducted in central and northeastern Florida
(for previous studies, see
Subsurface Characterization of
Selected Water Bodies in the St. Johns River Water Management District, Northeast Florida).

The field operation presented a series of unique logistic challenges because many of the canals are
narrow and difficult to access and the geology is limestone. SFWMD personnel were crucial in providing
help with gate keys and lifts for getting the Jon boat into and out of the canals. Preliminary review of the
seismic-reflection profiles indicates that the data are usable but data quality vary widely. Indications are
that some acquisition methods need modification to improve data quality. Stay tuned for future updates.
