NGDC "073" format for physical properties of marine sediments: format.073 file obtained from: U.S. Department of Commerce National Environmental Satellite, Data, and Information Service National Oceanic and Atmospheric Administration U.S. National Geophysical Data Center (NGDC) & co-located World Data Center for Marine Geology & Geophysics, Boulder NOTE: The "073" format was created by NGDC in 1976 and has been modified multiple times by NGDC. Please feel free to use the "073" format. Modifications to the "073" format must be approved by NGDC (including addition of new code types) in order to use the "073" format designation. for technical assistance please contact: Carla Moore National Geophysical Data Center E/GC3 325 Broadway Boulder, CO USA 80305 phone: 303-497-6339 fax: 303-497-6513 email: carla.j.moore@noaa.gov _______________________________________________________________________ "073" EXCHANGE FORMAT DOCUMENTATION ____________________________________________________________________________ Format for Geotechnical/Grain Size Data Summary of Header Reports Title Record Type Contents ----- ----------- ------------------------------------------- Cruise Header A Institution Code, Ship Code, Cruise Identifier, NGDC Unique No., Institution Name, Ship Name, Scientist, Report Number Reference Header B Funding Code (2-digit code supplied by NGDC), Project Code, Title of Report or Comments, Units Codes. Sample Header C Sample Identifier, device code, date of collection, time of collection, latitude, longitude, water depth, core length, device Cruise and Reference headers are coded once per cruise. Sample headers are coded once per station-sample (e.g. every time either a station or a sample identifier changes or device type changes). Analytical information is coded using the following record types: 1) Interval header 2) Optional comments record 3) Data records Each new interval within a core is noted with an "interval header," if a subcore or replicate is analyzed, a new "interval header" is also coded. Free-form comments applying to an interval, replicate, or subcore may be entered following the "interval header" using a "comments" record type. There are a large number of data record types. The coder should select only those types which apply to the analyses performed, and omit other data card types. Type of data provided for in this format include: grain size analyses - 02 record types geotechnical analyses - 08 record types geochemical analyses - 05 record types A complete description of data entry formats for all of these types of information follows. Common Fields ------ ------ For sorting and retrieval purposes, the following fields are common to, and occupy the same columns within, the record types indicated: Field Name Record Types Actual Entry...... ---------- ------------ ----------------------------------------------- inst all Contributor leaves blank, added by NGDC ship all " " " " " " cruise all Constant for all records for a given cruise sample C-X Constant for all records for a given sample device C-X " " " " " " " " subcore#, D-X Constant for all records applying to one interval#, interval, replicate, or subcore. replicate# Additional Information ---------- ----------- The basic unit of analysis for purposes of this format is the "replicate." A replicate may, depending on the analytical methods, be equivalent to a core interval or grab sample, or may be one of several sample splits. In either case, each replicate analyzed is represented in the data by an Interval Header record followed by one or more data records. If only one split was analyzed for each sample, the replicate number will always be zero. Fields which are not applicable (such as subcore and interval number in the case of a grab sample) are left blank. Subcore numbers are used only for small cores or spot samples extracted from box cores. All weight percentage fields contain two implied decimal places (no decimal points are coded). Code "9999" for 100%, "0000" for trace (less than 0.005%). All field lengths are in bytes. A = Alpha or alphanumeric fields (left- justified within field), 9 = Numeric fields (right-justified, balanced around any implied decimal position), X = blank field. ^ denoted an implied decimal position (99^99 is a four-digit numeric field with two implied decimal places). Cruise Header - coded once per cruise, this is the first record coded for a cruise.
