Abstract--SEDIDAT is a series of compiled IBM-BASIC (version 2.0) programs that direct the collection, statistical calculation, and graphic presentation of particle settling velocity and equivalent spherical diameter for samples analyzed using the settling tube technique. The programs follow a menu-driven format that is understood easily by students and scientists with little previous computer experience. Settling velocity is measured directly (cm/sec) and also converted into Chi units. Equivalent spherical diameter (reported in Phi units) is calculated using a modified Gibbs equation for different particle densities. Input parameters, such as water temperature, settling distance, particle density, run time, and Phi.Chi interval are changed easily at operator discretion. Optional output to a dot-matrix printer includes a summary of moment and graphic statistical parameters, a tabulation of individual and cumulative weight percents, a listing of major distribution modes, and cumulative and histogram plots of a raw time. settling velocity. Chi and Phi data.

The programs presented herein direct the collection, statistical computation, and graphical presentation of settling velocity and particle-size data for sand and coarse silt sediment samples analyzed using the settling tube technique. SEDIDAT is designed for easy use in both research and instructional applications, and its operation requires no sophisticated under- standing of computers or statistical methods. The programs operate through a series of menu-driven steps that allow maximum flexibility in parameter selection. SEDIDAT differs from previously pub- lished particle analysis programs (Kane and Hubert, 1963; Collias and others, 1963; Schlee and Webster, 1967) in that it analyzes continuous settling velocities rather than grouped sieve data, and utilizes the most recent refinements to velocity and velocity-size Con- version equations. SEDIDAT functions on a microcomputer (IBM PC-XT), and provides monochrome screen graphic support with optional output to a standard dot-matrix graphics printer (Epson FX-80).

Particle-size and velocity data are of sedimento- logical interest for their descriptive value in deter- mining lithologic character, as well as for their poten- tial interpretive value in reconstructing sediment- transport history and dcpositional environment. Actual products of the analysis are particle-settling velocity values. SEDIDAT reports these in terms of velocity (cm/sec) and 7. (Chi):

where s is settling velocity expressed in m/see :tnd s,. i~; a standard velocity of I m/see (May, 1981). Velocity values may be used directly, or converted to equivalent spherical diameter for comparison to particle-size data. SEDIDAT size conversions arc reported in q~ (Phi) units:

~b = - I o g , ( d / d , , ) (2)

where d is diameter in mm and d, is a standard diameter of I mm (Krumbein, 1934; McManus, 1963). The long history of the development and application of sedimentation techniques for particle-size analysis is beyond the scope of this paper; however the interes- ted reader is referred to excellent summaries in Gibbs, Matthews, and Link (1971), Blatt, Middleton, and Murray (1980), and May (1981) for further information.

SYSTEM llARDWARE

The settling tube system for which this program operates was modified after the Rice University Rapid Sediment Analyzer (Anderson and Kurtz, 1979). The basic configuration (Fig. I) consists of a Gould Model UC3 universal transducing cell from which a v,eighing pan is suspended at the bottom of the settling column. The signal from the transducer is amplified and con- ditioned (Fig. I), then read by an IBM PC-XT microcomputer equipped with the DOS 2.0 operating system, a Hercules Graphics Card and associated GRAPH X software, 640 K RAM, and a 10-bit Data Translation A/D converter and control clock.

640 K RAM is required to run SEDIDAT. Input and output signals of the amplifier/conditioner unit are monitored by an inexpensive oscilloscope and volt- meter to insure that all electronics are functioning properly before and during data collection.

The amplifier on our system is a custom circuit designed to amplify the strain gauge output, to filter out 60 Hz noise, and to provide a high degree of signal isolation between the computer and strain gauge. Most A/D boards have fair isolation qualities built in; however, for the small signals output by the strain gauge, a high gain, linear amplifier with noise filtering followed by a second isolation stage was determined to be critical for obtaining reliable, low-noise scans.

SEDIDAT

General information SEDIDAT (Appendix I) is a series of menu-driven

programs for settling velocity data acquisition (DIRT), statistical analysis (STAT), and graphic plots (PLOT). The operator can move quickly from one program to another through the main menu (Fig. 2). A unique system number, assigned in DIRT, identifies the data set throughout successive operations.

Standard SEDIDAT output (Appendix 2) provides an interval listing of cumulative and individual weight percents for Chi and Phi data. Grouped moment (McBride, 1971) and graphic (Folk and Ward, 1957) statistical measures of mean, standard deviation, skewness, and kurtosis are provided for both data sets, and are based upon specific Phi and Chi sample intervals selected by the operator prior to STAT analysis. The program outputs the five largest distribution modes and tabulates these according to weight percent. Input parameters, equation variables, and constants are summarized. Optional output plots include: (I) cumulative curves of Phi, Chi, settling

DIRT program The DIRT program (Appendix 1) collects strain

gauge data through an A/D converter, and stores data and analysis parameters. The following information is input by the operator:

(I) A system number that identifies the data set in subsequent operations. Format includes drive specification for data storage, a unique six character label, and the file name extension .DAT (example: A:TI0369.DAT).

(2) A descriptive sample name. (3) Total particle settling distance. (4) Water temperature. (5) Total analysis run time.

DIRT collects 1000 data points during a single analysis. Time between points varies depending upon total run time selected. A linear equation computes the correct delay loop index (counter) to delay appro- priately between each data point collected. The cons-

57

tants in this equation were determined by a plot of time (see) vs the index of the loop. fitting a least- squares line to the points, and using the resultant linear equation to determine the loop index for a desired delay. The program waits for the operator to press "'return" on the terminal to start the sample run. Data acquisition starts immediately following the last of three warning beeps to coordinate sample introduction into the settling tube. At the end of the sample run, data are stored in the disk file along with parameters entered by the operator (settling distance, water temperature, etc.) and those parameters calculated (elapsed time, date, etc.).

STA T program STAT (Appendix I) generates grouped moment

(McBride, 1971) and graphic (Folk and Ward, 1957) statistical parameters and calculates individual distribution modes for data collected in the DIRT program. At this stage, the user selects the desired Phi and Chi intervals by designating the appropriate number of subdivisions per unit. Values may range from whole Chi or Phi units to 1/20 Chi or Phi units. Statistical information then is stored using the orig-

Velocity values are calculated from raw time and settling distance, and are converted to Chi values using Equation (I). The conversion from settling velocity to equivalent spherical diameter is made using a modified equation of Gibbs, Matthews, and Link (197 I). The original equation:

r = 0.055804V"er + 0.003114V4Q~ + [g(Q~ -

where r = sphere radius (cm); V = velocity (cm/sec); n = dynamic viscosity of fluid (poises):g = acceleration of gravity (cm/sec): ,o: = density of fluid (g/cm ~); Q, = density of sphere (g/cm~), was derived empi- rically to enable analysis of coarse-grained particles that settle outside the application limits of Stokes' law (Stokes, 185 I: Rubey, 1933). Komar ( 1981) confirmed the accuracy of the Gibbs" equation based upon a theoretical evaluation of Reynolds number and drag coefficient conditions, and introduced a set of correction factors that improve the application limits of the equation. These factors, employed by STAT, are important particularly for substantial particle density deviations from glass spheres; and greatly increase the accuracy of the Gibbs' equation for sediment distributions containing abundant heavy (i.e. heavy mineral) or light (i.e. Foraminifera shell) components. Selec- tion of appropriate particle-density values and selec- tive use of the Komar correction factors is made through menu format. Conversion of size data to Phi units is by Equation (2).

For both Phi and Chi data sets, STAT calculates grouped moment and graphic statistical measures of mean, standard deviation, skewness, and kurtosis (Table I). All inflection points on the Phi and Chi cumtdative curves are computed and the five largest modes are tabulated by weight percent.

Graphic computations [Table 1, Eqs. (!. I)- (!.4)] are based upon a few selected cumulative percent values, and were introduced prior to widespread computer access to reduce the lengthy calculations charac- teristic of moment 'statistics. STAT reports graphic statistics (Folk and Ward, 1957) for the purpose of comparison to other similarly calculated data sets. Moment statistical measures utilize the complete 1000 point data set and, therefore, are the preferred statistical method. STAT performs grouped computations [Table I, Eqs. (I.5)-(I.8)1 using the equation forms in McBride (1971). In a comparison of grouped vs non- grouped moment parameters, Swan, Clague, and Luternauer (1979) concluded that particle size errors induced by grouped data calculations were small (< I%), particularly in the situation of grouping intervals <0.5 Phi. By using the standard grouped equations, STAT results may be compared to other data generated by similar grouping techniques (such as sieve analysis), if desired, however, STAT allows selection of grouping intervals as small as 0.05 Phi and thus eliminates grouping error.

PLOT program Several selections in plotting options (Appendix 2)

are available to the user from the PLOT menu. The data from DIRT and STAT are read and appropriate scaling factors are calculated. Cumulative data may be presented as a function of time, velocity, Chi, or Phi (Figs. A I-A4). Frequency plots can be plotted as a function of time (the first derivative) or histograms

Qt)(4-5nI" + 0.0087051/:Qf)]g(e~ - el) (3) [ I

of velocity, Chi, or Phi. Velocity histograms are in l-see increments. The user-defined interval selected in the STAT program determines the width of bar scales in histograms of Chi and Phi. Each plot appears first on the screen and, if desired, a hardcopy may be obtained using a graphics printer.

Program modificathm Modification of SEDIDAT software for other

computer systems could range from a minor to major process, depending upon system hardware diffe- rences. The programs are designed for use on IBM PC and compatible equipment. Substantial software modification would be required for use on alternative hardware systems. Constants in the timing (delay) loops in the DIRT program would need redetermi- nation to compensate for CPU speeds different than the IBM PC-XT (see di~ussion of DIRT for details). Graphics commands (GRAPI! X) would change somewhat if a card other than the Hercules Graphics Card in employed. Ten-bit A/D resolution is defin- itely adequate for this type of data acquisition; however 12-bit resolution along with programmable gain could be used effectively to enhance the process. No need currently exists for 14- or 16-bit A/D resolution. Uncompiled BASIC was used in an early version of SEDIDAT, but program execution was slow (over 10min each for STAT and PLOT). Therefore, compiled BASIC (IBM-BASIC, version 2.00) is used for all SEDIDAT programs.

OPERATIONAL CONSIDERATIONS

The settling tube system and accompanying SEDIDAT software package described here permit accurate analysis of sands in the range of 0--4.0 Phi. Samples finer in size than 4.0 Phi should be analyzed by alternative methods (for example: pipette, X-ray/ light absorption, or laser methods) because of ex- cessive analysis time and problems of turbulent settling. SEDIDAT software was verified using density- and size-calibrated National Bureau of Standards (NBS) glass spheres. Calibration samples ranged (in 0.25 Phi increments) from 0.5 to 2.25 Phi and from 3.0 to 4.5 Phi. Settling tube data using SEDIDAT programs agreed well with NBS values in the range 0.5- 2.25 (within + 0.05 Phi), moderately well with values

Analysis of particle

in the range 3.0-3.5 Phi) (within + 0.2 Phi) and poorly with NBS values in the range 3.5--4,5 Phi (within + 0.4 Phi). Inaccuracies in finer samples result from particle interaction and visible turbulent settling of the finer grains. These problems have been recognized in settling tube analyses (Blatt, Middleton, and Murray, 1980), and reflect problems of sample introduction rather than software flaws. Until sample- introduced turbulence is minimized, the practical lower limit for reliable sedimentation results is the sand-silt boundary (4.0 Phi). Factors which may help eliminate these problems might be (I) refined sample introduction mechanisms, or (2) smaller sample size.

Opt imum sample size for SEDIDAT analysis falls between 0.8 and 1.2g. which makes the technique

part icularly useful for applications in which total available sample is small. In our experience, system electronic noise becomes a problem for samples smaller than 0.8 g. Analysis time is variable depending upon selected settling distance and range of particle size. A standard sand run requires < 10min for a settling distance of 140cm. Analyses into the coarse silt range (to 4.5 Phi) require up to 20min per sample.

The ability to analyze small samples in a short amount of time is standard with settling tube hardware. The advantages of the S E D I D A T software lie mainly in the flexibility of input parameters and the incorporation of recent modifications (Komar. 198 I) to the velocity equations. SEDIDAT users select among a range of water temperature and particle density variables most appropriate for a variety of natural terrigenous and biogenic samples. Both settling velocity and equivalent spherical diameter data are produced; and, equally important, statistical grouping intervals are user-defined. Limitations seem to be mechanical in nature, and are related to turbulent settling of the finest particle sizes. Improve- ment in sample introduction and reduction of minimum sample size may reduce ultimately these errors to allow reliable analysis of the coarse silt fraction.
