D 1.1 IntroductioD
Data are only oflimited value unless the protocols used in their collection are known.
This information, or meta-data, is included as aseries of data documents on the CD-ROM. The subdirectory structure is designed to mimic the structures used for the data. F1lenames have also been designed to be as similar as possible: identical filenames are not possible in all cases because sometimes a data document covers more than one data file.
The data documents are all held in the subdirectories of the directory DOCU.
Three copies of each document file are included on the CD-ROM. The first is a simple flat ASCII file. This has the advantage of being universally accessible but lacks the aesthetic appearance one associates with modern laser printed documents. The second copy is in PostScript format and may be printed on a PostScript printer with Times Roman font available. The third copy is in the internal format of the WordPerfect 5.1 word processor which should import, complete with layout, into most modern word processors. The versions of the document file are distinguished by their file extension. This is set to .1XT for flat ASCII files, to .PS for PostScript files and to .WP for WordPerfect 5.1 files.
Users of Windows will find that File Manager is a very powerful tool for browsing through the documentation. The files in each directory are clearly displayed.
Moreover, double clicking on the icon for any .TIIT file williaunch Notepad with the file loaded, enabling the document to be read. Note that a small number of the documents are too large for Notepad and consequently may not be read in this manner.
Altematively, users may establish a linkage in File Manager between the .WP extension and their favourite word processor. If this is done, double clicking a .WP file icon will launch the word processor with the appropriate document loaded.
D 1.2 Subdirectory DOCU\DBKIT
This subdirectory contains the data documents covering the files which comprise the
'kit-form' database. The documents are stored in a structure which mimies that used for the aetual data.
01.2.1 Subdirectory DOCU\DBKlT\SEASOAR
The Seasoar data presented on the CD-ROM were eolleeted during two eruises in 1990, Diseovery 190 and Diseovery 192. There is one doeument for eaeh eruise and the lles are named after the eruise mnemonie (e.g. DIl90 for Diseovery 190).
01.2.2 Subdirectory DOCU\DBKlT\CTD
The CTD data set is documented on the basis of one document per eruise. The document name eorresponds to the eruise mnemonie. For example, the doement files pertainingto Discovery 182 are DOCU\DBKIT\CTD\DIl82.TXT (flat ASCII), DOCU\
DBKIT\CTD\DIl82.WP (Word Perfeet 5.1 format) and DOCU\DBKIT\CTD\DIl82.PS (PostScript format).
There are two additional doeuments deseribing data sets eollected from other instruments whieh were deployed on the CTD frame. The first of these, 02PROF, deseribes the Endeeo oxygen prolles obtained during Diseovery 182 whieh are held in the lle DBKIT\CTD\02PROF. The seeond, MSP, deseribes the marine snow proller data held in DBKIT\CTD\MSP.
01.2.3 Subdirectory DOCU\DBKlT\BOTNET
This subdirectory eontains the following doeuments whieh map simply to the data files stored under DBKIT\BOTNET. The names in braekets are the data lles eovered by the doeument flle.
- Measurements of earbon and nitrogen - Phytoplankton speeies distributions
Calibration sampIes (salinity, dissolved oxygen and reversing thermometer temperatures) - Dissolved and partieulate radionuclides - Optieal seattering measurements - Cyanobaeteria and phyeoerythrin - Chlorophyll and other pigments - Lipid biomarkers
- Nutrients
- Sulphur speeies (DMS, DMSP) - Dissolved aluminium
- Mesozooplankton biomass, grazing and gut eontent
- Mierozooplankton grazing and biomass
01.2.4 Subdirectory DOCU\DBKlT\PROD
This subdireetory eontains the following doeuments. deseribing the varied ineubation
experiments undertaken during BOFS, which map simply to the data files stored under DBKIT\PROD. The names in brackets are the data files covered by the document file.
C14PROD (C14HDR, C14DAT, PIDAT - Primary Production by l4C C14SURV, C14CALC)
THYPROD (THYDAT, THYDIU) - Bacterial production by 3H-Thymidine and 3H-Leucine. Bacteria cell counts.
- Oxygen, TC02 and pC02 production 02PROD (OXYHDR, OXYDAT)
N15PROD (N15HDR, N15DAT) NOXPROD (NOXHDR, NOXDAT)
- New and regenerated production by 15N - High resolution N03 uptake experiments D1.2.5 Subdirectory DOCU\DBKlT\SAP
This subdirectory contains the following documents, describing the data sets obtained using Challenger Oceanics stand-alone pumps (SAPs), which map simply to the data files stored under DBKIT\SAP. The names in brackets are the data files covered by the document file.
RADNUC (RADSAP) LIPIDS (LIPSAP)
PIGMENT (PIGMENTI, PIGMENT2, PIGMENT3)
- Dissolved and particulate radionuclides
- Lipid biomarkers
- Chlorophyll. carotenoid and particulate carbon data D1.2.6 Subdirectory DOCU\DBKlT\CORE
This subdlrectory contains the following documents. describing the BOFS benthic data set, which map simply to the data files stored under DBKIT\CORE. The names in brackets are the data files covered by the document file.
LIPSED
(KASCHEM. KASGEN. KASISO.
KASSED, KBFHEAD. KBFDAT) (PBISO, UTHISO)
Profile data sets obtained from Kasten cores
- Radionuclide profiles
- Multicore bulk property and chemistry profiles
D 1.2. 7 Subdirectory DOCU\DBKlT\SEDTRAP
This subdirectory contains a single document, SEDTRAP. which describes the data sets obtained from the BOFS moored sediment traps. 1t covers all the data files in DBKIT\SEDTRAP. namely:
STCN STCNFX STRD
Carbon, nitrogen and opal content Mass, carbon. nitrogen and opal fluxes Radionuclide content
STRDFX STSPFX
Radionuclide fluxes Taxon fluxes
D1.2.8 Subdirectory DOCU\DBKIT\CURR
This subdirectory contains a single document, ARGOS, which describes the Argos Drifting Buoy data set held in DBKIT\CURR\ARGOS.
D 1.2.9 Subdirectory DOCU\DBKIT\XBT
This subdirectory contains a single document, XBT, which describes the Expendable Bathythermograph data set held in DBKIT\XBT\XBT.
D1.3 Subdirectory DOCU\SATIMG
This subdirectory contains a single document, SATIMG, which describes the methodology used to obtain the satellite images contained in data directory SATIMG.
Abrief description of the images is included, together with references to papers in the literature which describe the oceanographic features they portray. The contents of this document (in flat ASCII format) is also included in the README.TXT file in the SATIMG directory.
D1.4 Subdirectory DOCU\UNDERWAY
The underway data set is documented on the basis of one document per cruise. The document name corresponds to the cruise mnemonie. For example, the document files pertaining to Discovery 182 are DOCU\UNDERWAY\DIl82.TXT, DOCU\
UNDERWAY\DIl82.WP and DOCU\UNDERWAY\DIl82.PS.
