The documentation available in PDF format and in Excel tables.
Available data
The data processing steps that lead to these data are described in detail
and available from the report "University of Florida
Data Set on SmallScale Sediment Processes from SandyDuck'97",
and will be briefly reviewed here.
Initially, the data was recorded in continuous runs. Each of the runs
can consists of several *.DAT files and may have *.MTA
data file for the MTA measurements. Not every run has the MTA data.
The duration of the runs vary according
to the measurements settings and reaches several hours. The MTA measurements
usually cover most of the run, starting from the beginning of the run.
The measured raw data was converted into physical units (please, check
the document mentioned above for more details
on variable conversion); the *.DAT files for one run were
combined into one *.MAT file which is saved in Matlab format.
Thereafter, each run was splited into several bursts of 34
minutes of length for calculation of statistical quantities. These files
were saved in Matlab format as well. The types of available data are
summarized into Table 1.

Information plots 
Graphical files in *.PNG format

Summary data tables
Since the volume of the data is very large, several summary
tables were created, which gather a lot of statistical information from the
data files. The section Statistical plots presents
some of various measured parameters for the period of experiment.

Original UF filename convention  See renamed FRF format below, Table 2b
The name of each file is a standard UF naming convention that
contains information about the date and
time of data acquisition in the following format:
Table 2a. UF filename convention
Format: dMDhmmNN 
d  first letter used to identify the overall experiment 
M  indicates month, ex. 9  Sep., a  Oct., and b  Nov. 
D  indicates date, ex. a  10th and k  20th day of the month 
h  indicates time, ex. 8  08:00am, b  11:00am, g  16:00pm 
mm  indicates minute 
NN  Can be one digit, two digits or zz.
One digit used for raw and MTA data  file number within a run (0, 1, :)
Two digits or zz used for 34 minutes data files  file number within a run (00, 01, ...);
zz used for shorter files (last file of the run)

Format: UFDH_yyyymmdd.hhMM.ss.GGG.mat 
UFDH  University of Florida, Dan Hanes 
yyyy  indicates year 
mm  indicates month 
dd  indicates day 
hhMM  start time (EST) of a run (several consequitive sequences) 
ss  Can be one digit, two digits or zz.
One digit used for raw and MTA data  file number within a run (0, 1, :)
Two digits or zz used for 34 minutes data files  file number within a run (00, 01, ...);
zz used for shorter files (last file of the run) 
GGG  indicates file type: SPI, ABS1, ABS2, ABS5
