A PROCESSING SYSTEM FOR AANDERAA CURRENT METER DATA

R. L. CharnellG. A. Krancus

ABSTRACT. Several projects being conducted by thePacific Marine Environmental Laboratory (PMEL) involvedirect measurement of current using the model RCM-4Aanderaa current meter equipped with conductivity,temperature, and pressure sensors. At present, PMELhas over 100 RCM-4 I s and obtains 200-300 current meterrecords per year. To cope with this volume of data,PMEL has developed a processing system to rapidlyapply corrections and produce several routine productsused in subsequent data analysis. This technicalmemorandum describes this processing system.

1. INTRODUCTION

The strength of the PMEL Aanderaa current meter processing system liesin minimizing the manpower normally required to reduce current meter data.Because of the high current meter use rate it is imperative that data fromrecently returned current meters be examined rapidly to insure proper opera­tion of the meters prior to their recommitment to the field. By reducingthe manpower for data processing, more time can be spent in the scientificanalysis of data.

To process a given meter tape the average time spent by an oceano­graphic technician is 5 hrs, and processing can be completed in an elapsedtime of a few days. Normally four or more meter tapes are processed atone time, so that all output products described below may be ready withina week from the time the actual tapes enter the laboratory. This is asignificant improvement over the 2 to 4 months currently experienced inother parts of ERL (D. A. Mayer, AOML, personal communication). The proc­essing package was developed for the scientist. However, several of thedisplays and tabulated data rapidly convey a visual summary of a largevolume of current meter data. Thus this package can be used by a programmanager to rapidly assess progress of a project. Such a management toolis the plotted output that succinctly presents processed data and flowcharacteristics on a single figure.

Processing consists of four phases: (1) translation, (2) conversionof coded data to engineering units, (3) editing, and (4) product genera­tion. The translation is done with an electromechanical system whichreads the signal and checks parity of each record. The data are thenwritten on a computer compatible tape for subsequent operations. Thistape is then run through the computer, in our case a CDC-6400, for con­version and cleanup. This results in production of a printout of all data,including error analysis, and of an interim data tape. The third segment

of the system, editing, is currently being done solely by technicians.We are now in the process of automating this portion of the work. Eventu­ally data will be processed with a single computer pass and hence eliminatethis time-consuming interruption. The last phase of processing takes theclean, edited data through several filtering and calculation steps. Outputfrom this phase is a processed data tape for use in future analyses, a sum­mary printout,and a plotted presentation of all data.

The data generated by the RCM-4 I s have few errors. The largest por­tion is related to the time base. Periodically the electromechanicalsystem will fail to read an existing synchronous (sync) pulse signal onthe data tape and hence generate an extra record, apparently lengtheningthe observation time. However, the extra record produced is either incom­plete or zero-filled and results in a parity error. By keying on the syncpulse during translation and continuously checking parity the few time­base errors generated can be identified and eliminated. It is this identi­fiable signature which should allow comprehensive editing of these data bycomputer and eventually result in single pass processing. Other errorsencountered are values which exceed the normal ranges. These errors areusually caused by the current meter encoding circuits and, although neverresulting in a parity error, they do follow a specific pattern. Again,they are identifiable and easily corrected. The combination of a lownumber of errors and their easy identification is key to the rapid process­ing of these current meter data.

Our experience has shown a total number of errors less than 1% ofeach record. The low number of errors in the records is not accidental.Each meter is examined in detail before deployment with all contact pointsof the digitizer thoroughly cleaned and electrical circuits checked.Rapid translation of the data tape from the previous deployment gives a6-channel strip chart record, allowing identification of specific mal­functions to be rectified. After the check and spot calibration, a datatape is produced and checked. While not part of the post-operation proc­essing, this stage in the total operation is critical to production ofreliable data.

The PMEL processing system for Aanderaa current meter data relies onthe identification and removal of errors as part of the processing system.It simultaneously generates several products, rather than waiting forsequential checking of the data at the end of each operation. It must berecognized that checking of the data at each stage is as necessary asbefore. However, processing in a simultaneous mode allows an early exami­nation of data to aid in equipment turnaround, future field planning, andrapid data analysis. Since subsequent checking rarely turns up errors inprocessing, this approach is worth the gamble.

2. ELEMENTS OF THE SYSTEM

The data processing procedure starts with the original O.5-mil datatape created by an RCM-4 Aanderaa current meter. This tape is removedfrom the meter with no rewinding and rerecorded onto a stronger 1.5-mil

2

working tape. The delicate 0.5-mil tape is then stored and ordinarily isnot replayed under normal circumstances. The working tape is then proc­essed by the system depicted in figure 1. The elements of this system aredescr"ibed below.

2.1. Translation

The Aanderaa tape translator was designed and built by PMEL. It isused to read the 1.5-mil working data tape and to rewrite this data on amedium-density (556 bpi) computer compatible 7-track raw data tape. Be­sides the raw data tape, the translator also produces a 6-channel stripchart. This is an invaluable aid in early detection of a current metermalfunction and in verifying the quality of the data.

The RCM-4 current meters use a dual-channel tape recorder with chan­nel A being an exact duplicate of channel B, except that one channel maybe more readable than the other. The meter records six 10-bit words inserial form followed by a sync pulse. Each 10-bit word is read by thetranslator and expanded into two 6-bit characters by inserting flag bitsafter the fifth and tenth input bit. Each character is then packed intoa 400-character output buffer. After each word is read a check is madefor the sync pulse. When it is encountered, a 2-character (12-bit) errorword is transferred to the output buffer. The reader can detect incorrectbit counts within words in addition to incorrect word counts between syncpulses. Any discrepancies are encoded and written in the error word.Hence, for every data frame (six 10-bit words) that is read from theworking tape, seven 2-character words (12-bit words) are written to theoutput buffer. The output buffer is finally dumped to tape, in odd parity,when 25 frames have been processed. The translation phase of processingis complete when the entire working tape has been read. The resulting rawdata tape is then taken to the CDC 6400 for all subsequent phases of proc­essing.

2.2. Conversion Program (AANCMRD)

The first computer function performed on the translated data is doneby the conversion program (AANCMRD). AANCMRD reads the tape, created bythe translator, converts raw data into engineering units, makes a listingof the data in both forms, and creates an intermediate tape used for editing.The program is written in CDC FORTRAN version 2.3 and uses some nonstandardsubroutines that have been implemented on the University of Washington'sCDC 6400. Inputs to this program include the calibration equations, themagnetic deviation at the mooring site, the time interval between records,and the type of speed sensor used.

The actual processing done by AANCMRD is in two steps. First, trans­lated data are read in, unpacked, the sync pulse (which is encoded in thesixth and twelfth bit of the sixth word) located, and the error word ischecked for any problems the translator had with individual records. Un­packing consists of restoring the data to their original form by removingbits 6 and 12, then compressing everything to the right. The data are then

converted, salinity computed, and any bad records are written on OUTPUT(in our case the line printer). Step two involves generating a summaryof bad records, removing negative speed values, and writing all converteddata on both TAPE3 and OUTPUT. The next phase in processing is hand edit­ing. This process identifies bad values, rectifies the time base, andproduces correction cards for improving the data on TAPE3. These cardsplus TAPE3 are the input to the edit program (EDTDAT) where these correc­tions are applied.

2.3. Edit Program (EDTDAT)

This program uses as input the converted data tape created by AANCMRDand the edit cards generated in the hand editing step; AANCMRD's TAPE3 isnow called TAPE1. Output from EDTDAT includes a clean data tape and list­ing, plus a Data Summary Report. Like AANCMRD this program also is writtenin CDC FORTRAN version 2.3 but does not use any locally implemented sub­routines.

EDTDAT can add, change, or delete records by proper selection of con­trol parameters on the individual edit cards. The time base that was estab­lished and verified by hand editing is used to assign a date-time groupto each record. The value for speed, which is taken by rotor counter, isconsidered to be the speed at the time the direction and sensor readingswere recorded. The U and V components of velocity are computed at thistime. Following this correction phase of processing the data are filteredto remove high frequency noise and filtered a second time to remove thetidal portions of the signal.

2.4. Filters

The program which does the filtering also calculates total energyspectra and determines extrema for a Progressive Vector Diagram (PVD) tobe drawn in the plot step. Filtering and spectral analysis are carriedout using a general time series analysis package known as FESTSA. Thispackage of subroutines was developed initially at the University of Hawaii,modified extensively at the University of Miami, and is currently beingmaintained by NOAA at AOML, Miami, and Suitland, Maryland. The copy ofFESTSA used here is written in CDC FORTRAN EXTENDED version 4.

The U and V components of velocity are convolved with two separatetwo-sided Lanczos filters. The first is a low pass filter with a responseof 6 db down at a period of 2.86 hrs and is such that less than 0.1% ofthe amplitude is passed at periods of 2 hrs and more than 99% of the ampli­tude is passed at periods greater than 5 hrs (see fig. 2). Output fromthis step yields one data point per hr with 4-hr starting and stoppingtransients lopped off each end.

The second filter removes most of the tidal energy with a responseof 6 db down at a period of 35 hrs such that 0.1% of the amplitude ispassed at periods of 25 hrs while 99% is passed at periods of 55 hrs (seefig. 2). The resultant time series from this operation yields one data

point per 6 hrs with 60-hr starting and stopping transients lopped offeach end. The output from each filter is copied to tape and preserved forfuture reference.

The total energy spectra is calculated from the 2.86-hr filtered t~meseries such that the ensuing numbers represent an ensemble averaged perlodo­gram. The complete operation is actually performed in two steps. Firstthe time series is broken up into 360-hr segments, the mean value removed,and the 1as t segment zero fi 11 ed. The Fouri er coeffi ci ents are found foreach segment and the ensemble averaged spectral energy is then computed.This yields 36 bins. Next, the series is broken into 120-hr segments andthe same manipulations are performed. This yields an additional 12 binsfor a total of 48 bins for each component. The Uand V components arethen summed. The spectrum represents the distribution of variance amongthe 48 frequencies and generally accounts for about 95% of the total vari­ance. Output from the spectral and PVD computations are written on ascratch file (TAPE4) and passed to the plot program.

2.5. Plot Program

This program makes use of the clean data created by EDTDAT, the fil­tered U, V time series, and the spectra. Additional information is givento the program via control card input. The program is written in CDC FOR­TRAN EXTENDED version 4 and utilizes standard CalComp subroutines. Outputsinclude pertinent mooring information and some statistics, a spectral plot,a progressive vector diagram, and plots of various parameters versus time.

The parameters plotted against time include U, V, temperature, pres­sure, and salinity. Plotting the latter three data sets is optional andmay be turned off. The U and V components are passed over twice: firstfor the PVD and second·for the time series plot. The second is done inlO-day segments such that the origin is reset at the beginning of eachlO-day set. Th is mi ni mi zes the amount of central memory requ i red for datastorage.

Under normal circumstances, the filter program and then the plot pro­gram are executed in the same job stream. This is essential if one wantsthe spectral plot as this information is passed, via a temporary file(TAPE4), between the programs. Other information on this file includesthe PVD bounds, the variances, and the mean pressure.

3. INPUT FORMATS

There are various types of input to the processing system. Each hasa distinct format that is described in this section. In addition to thecomputer compatible tape format that results from the translator, the cardformats for controlling operations, functions, and data corrections aredescribed.

3.1. Conversion Inputs

AANCMRD (the conversion program) takes two types of input: one is theraw data tape created by the translator and the other is seven punchedcards with the mooring and calibration data. The raw data tape has 25Aanderaa records (seven 12-bit words per record) packed into one physicalrecord or block followed by a 3/4-in tape gap. It is a 7-track, odd parity,556 bpi computer compatible tape. The data fields are written in the order:reference word, temperature, conductivity, pressure, direction, and speed.It may be read most effectively by using a FORTRAN BUFFER IN statement (seesubroutine GETREC of AANCMRD).

The seven punched cards are a major source of errors and must be re­viewed upon successful execution. In general, card 1 is a combination ofcorrection factors and program control fields, cards 2 through 5 have thecalibration equations, and cards 6 and 7 have header information for theoutput data tape. Formats for these cards are:

IThis number is taken from the translator which counts the number of goodrecords plus the number of bad records. It should be verified with a roughcalculation.2NFSKIP is normally set to zero since this is a very inefficient way to skipfiles. It is better to use existing system utilities for file positioning.3NUMETR may be either T or F. T implies that the speed sensor used resetsitself to zero after each reading. F implies that it is the constant accumu­lation type which is reset to zero when the counter reaches 1023.4It is important that the speed sensor gear ratio be figured into this con­stant. For a gear ratio of 4 to 1, this number is around 2.76. Similarly,for a gear ratio of 2 to 1, it is about 1.5.

3.2. Edit Inputs

EDTDAT (the edit program) takes two inputs; one is the blocked binarydata tape created by AANCMRD and the other is one or more punched cards.The magnetic tape has two header records on it followed by the actual datarecords. The first header has the following information in the order:project, mooring, meter, meter depth, latitude, longitude, and bottom depth.This header may be changed if the information is poorly formatted orinaccurate. The second header has the start time, day, month, and year.

9

Both of these headers are written on the clean tape but the start timesare modified to reflect the fact that records will have been deleted fromthe beginning of the series. The individual data records from AANCMRD havedata stored on them in the following order: record number, speed, direction,temperature, conductivity, pressure, and salinity.

Only one punched card is necessary to make EDTDAT run. It has allthe information on it to assign date-time groups to the data records andto delete any starting and stopping transients. The rest of the cardsare optional and are used for editing the individual records. It is pos­sible to add, delete, or change records by proper manipulation of the lead­ing entries on each card. The punched cards use the following format:

lThis field is used to indicate that a change is to be made to the infor­mation on the first header record. If a T is entered the following cardin line must have the new header information in the same format as card 6of input to AANCMRD. If an F is entered, the first header record on theclean tape will be the same as on the converted data tape.21f new header information is entered it would actually be the second cardand the detailed record corrections would be on cards 3 through N. Toactually add a record or records the record just before the insertion pointmust be flagged as a record to be changed or dropped.3To change a record NREC1 should be positive. Even though only one fieldneed be changed, all fields must be present on the card. To delete a recordNREC1 should be negative and none of the other data fields need be present.

3.3. Plot Control

The plot program has four inputs: (1) the clean data tape, (2) thefiltered data tape, (3) one or two punched cards, and (4) statistical andspectral data. The heading information plus temperature, pressure, andsalinity data are taken off of the clean tape which is in blocked binaryform. The 2.86-hr and 35-hr filtered U and V components are on the fil­tered tape. This tape is also in blocked binary form with the data fromthe separate filters being written on separate files each of which has twoheader records like those on the clean tape. Before execution, these filesare copied onto two separate local files, TAPEl and TAPE2.

The first punch card is essential as it controls what plots will bemade and also provides scaling information. The format of this card isgiven below. The second card is optional and may be used when the PVDinformation normally transmitted via TAPE4 is not present. The statistics(the PVD range, U and V minimums, Uand V variances, and mean pressure)plus the spectral data (the amplitudes of the 48 bins and the confidenceintervals) are transferred directly from the filter program via the localfile TAPE4. Without this file no spectral plot can be made but the sta­tistics for the PVD and labeling will still be made if the second card ispresent. When TAPE4 and this second card are not present no PVD plot willbe made. The punch cards have the following formats:

4. OUTPUT PRODUCTS

Output from the system includes tapes, printout and plotted data.This section describes these products and specifies the various formats.

4.1. Converted and Raw Data Listing

The Converted and Raw Data Listing is generated by AANCMRD and is usedin the hand editing step. Besides a complete listing of the data otherinformation is given which must be verified to assure accuracy of the cleandata.

On the first page of output, all information which was read in frompunched cards is given. The calibration coefficients should be checkedat this point to ensure that the right numbers were used in converting rawdata into engineering units. Also, mooring information should be examinedsince this is what will be written on the header of the clean tape. Ofparticular importance here is the latitude of the station for this valueis used in the plot program to compute the inertial frequency.

On the second page of output, records in which the translator founderrors are listed. After this list is given the total number of datarecords processed and percentage of them found to be in error.

Next is the listing of all converted and raw data. An example of thefirst page is given in figure 3. It is the converted data shown in thispart that has been written on the converted data tape and will be used asinput to the edit program. The first thing to pick out of this listingis the first record recorded after the meter has been positioned in thewater for one complete sampling period and also the last record recordedbefore the anchor was released. The start and stop times should then beassigned and the time base verified. All the converted data must then bescanned for any obvious errors and the correction cards encoded. An inter­polation flag value of 1 is used to indicate that a negative speed wasfound and that the speed value given is an interpolation between the pre­ceding and following records. The last thing written on this output isthe PVD information. Since it is possible to go directly from the con­verted data tape to the plotted data summary, this information is usefulso that all meters on a string will be plotted using the same PVD scale.

4.2. Clean Data Tape and Printout

Of primary importance in this whole system is the clean data tape gen­erated by EDTOAT since this is the permanent record of the investigationand serves as the basis for all future analysis. This tape is 7-trackwritten in blocked binary, odd parity at 800 bpi. While this is a veryefficient configuration, it would be necessary to convert this into anotherform if it were to be sent off to another installation.

The first two records written on this tape are header records (seesection 3.2 for details). The rest of the entries are the data records

with information recorded in the following order: date, time, U, V,temperature, pressure, conductivity, record number, and salinity.

The clean data printout, shown in figure 4, is generated at the sametime as the clean tape. It is a printed record of what is on the tape andis used as a written confirmation of any strange events future analysismay uncover. In addition to the information recorded on the tape, thelisting also prints the speed and direction.

4.3. Summary Data Printout

The summary data printout presents mean values for each hour, eachday and each week of the record. Figure 5 is an example of the outputfor 7 days of record. Each of the seven major blocks of data on the pagerepresents 1 day. Data for each day are presented in hourly means in fourcolumnar sets of six rows each. Each hourly set is denoted by its Julianday and hour. For each hour, temperature and salinity means are calcu­lated from all values recorded for that hour. Sigma-t, shown in thefourth column, is a mean value calculated from the temperature and salinityvalues from that hour. The fifth and sixth columns show the vector­averaged values of speed and direction determined from all values recordedin that hour.

For each day, summary daily values for each measured commodity areshown in the line following the hourly summaries. Temperature, salinity,and sigma-t are arithmetic mean values of all data recorded during the day.Net speed is the vector-averaged speed of all recorded values that day inthe true north direction shown. Also shown is the mean of all speed valuesrecorded that day. Depth is the mean of all observed values from the pres­sure sensor.

Following the seven individual daily summaries is a line indicatingthe mean values for these 7 days. Net speed is the vector-averaged speedof all data observed during the week at the true north direction indicated.As before, the mean speed and depth are simple mean values for all dataobserved in the 7 days.

For the case of the week in which the observation period began orended, the week has fewer hourly values than the maximum 168 possible.The averages for both the day and the week are corrected for the reducednumber of values.

4.4. Plotted Data Summary

The plotted data contains several types of information. Figure 6shows a typical example but reduced in size for this publication. Normallythe figure elements are about 9 in (22.9 cm) high with the plot designedfor use on a 12-in drum plotter. The record depicted here is normallyabout 80 in (203.2 cm) long.

The first segment of the plot is a written summary of the record.The first two lines identify the station and the project. The next twolines, the position, and the fifth, water depth at that site. The nexttwo lines identify the meter by number and its level in the water column,measured from the surface. Mean pressure is calculated from all valuesover the usable record. Record length denotes the length of usable record.Net Drift is the vector-averaged speed over the entire record at the indi­cated direction; mean speed is the arithmetic mean of all speed values forthe record. The variances are in the U (East) and V (North) directions.

The second segment of the plot is a spectral energy diagram for thisseries. The vertical dashed lines denote the frequency of the daily (D)and semidai1y (S) tides and the inertial (I) frequency. The vertical lineof small squares indicates a scale chance of the abscissa from 0.2 cyc1es/day/in to 1.2 cycles/day/in. The line in the upper left-hand corner showsthe error band of the 80% confidence level for the left-hand scale. A simi­lar line in the upper right-hand corner shows the error band for the right­hand scale.

The third segment of the plot is a PVD for the entire record. Thebeginning of the PVD is denoted by an S; the end by an F.

The.fourth segment which constitutes the bulk of the plot, displaysthe time series of all data types recorded. The upper and lower hatchedlines show the time with a scale of 1 day/in divided into quarters of aday. The upper data line, pressure, presents the instantaneous values ofpressure relative to the mean pressure denoted in the first segment ofthe plot. The ordinate has a scale of 8 db/in. The second and third datalines are the East and North components of the record filtered with the2.86-hr low-pass filter. These data were resamp1ed hourly. The data linemarked CURRENT shows the 35-hr low-pass filtered data resamp1ed at 6 hrs.The data are shown in a vector time series with north depicted by the arrowat the left. If the coordinate system is rotated the arrow at the leftshows the new north axis. For the last two data records, temperature andsalinity, all recorded values are plotted unfiltered.

5. ACKNOWLEDGMENTS

This system was developed in pieces by many different individuals.R. M. Reynolds assembled the tape translator and initially developed theAANCMRD and EDTDAT programs. B. A. Walters was the first to use these partsin production and contributed to the debugging and modifying of the programs.The filters were done by C. A. Pearson whose knowledge of FESTSA has greatlyenhanced the analysis of the data. The critical eye of Richard Si11cox hasled to many major improvements at all levels, especially in the job streamnecessary to process many current meters at one time.

Development of this system was supported in part by the Marine Eco­systems Analysis (MESA) Program and Outer Continental Shelf EnvironmentalAssessment Program (OCSEAP) of NOAA's Environmental Research Laboratories.
