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 Small-Scale 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.

Statistics
Calculated statistics Matlab *.MAT and Excel *.XLS   Calculated statistics based on 34 minutes data files See section "Summary data tables"
Information plots Graphical files in *.PNG format   Plots of time series of pressure, velocities, suspended sediment concentrations from OBS and ABS 2MHz, and seabed position for each of 34 minutes data files; includes some general statistics (wave period, wave direction, depth, etc.) From FRF server

1SPI - single point instrument

2SSC - suspended sediment concentration

3The last file of the run can be shorter in duration.



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
dfirst letter used to identify the overall experiment
Mindicates month, ex. 9 - Sep., a - Oct., and b - Nov.
Dindicates date, ex. a - 10th and k - 20th day of the month
hindicates time, ex. 8 - 08:00am, b - 11:00am, g - 16:00pm
mmindicates minute
NNCan 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)

Table 2b. FRF filename convention
Format: UFDH_yyyymmdd.hhMM.ss.GGG.mat
UFDHUniversity of Florida, Dan Hanes
yyyyindicates year
mmindicates month
ddindicates day
hhMMstart time (EST) of a run (several consequitive sequences)
ssCan 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)
GGGindicates file type: SPI, ABS1, ABS2, ABS5
