Summary of Oceanographic and Marine Meteorological Observations on board Research Vessels

Return to Home
Oceanographic observation data are stored on the CD-ROM in the following seven files:
  1. Hydrographic data (file name: xxyymm.E)
  2. Subsurface temperature data (xxyymm.T)
  3. Subsurface current data (xxyymm.A)
  4. Plankton data (xxyymm.tp)
  5. CTD data (xxnnnn_1.ctd)
  6. XCTD data (xxnnnn.xct)
  7. BT data (xxbblll.bt)
where,
xx: Ship Code [listed in Table]
bb:Ship Code for BT data [listed in Table]
yy: Year (last 2 digits)
mm: Month
tp: Type of Plankton [ZP: zooplankton, PP: phytoplankton]
nnnn: Station number (4 digits)
lll: Station number (3 digits) for BT data.

Hydrographic data, Subsurface temperature data, Subsurface current data and Plankton data consist of ASCII records of fixed lengths (126 bytes except Plankton data [73 bytes]). Each record is separated by two characters like as in DOS, which characters are one "control M" (carriage return, ASCII code 0Dh) and one "control J" (line feed, ASCII code 0Ah). For a missing value, the character '-' (ASCII code 2Dh) is put in place of the measured value. The column of the element that was not observed is filled with blanks.

CTD, XCTD and BT data files consist of ASCII records of variable length. Each element is separated by the character ',' (comma, ASCII code 2Ch), and the column of the element that was not observed is filled with '-9'.

Marine meteorological observation data are stored on the CD-ROM in the following two files:

  1. Maritime meteorological data (DDDDYYYY.im1)
  2. Aerological data (yymmdd.aer)
where,
DDDD:Ship call sign [listed in Table]
YYYY:Year (4 digits)
yy: Year (last 2 digits)
mm: Month
dd:Day
Maritime meteorological data consist of ASCII records of fixed lengths (131 bytes). Aerological data consist of ASCII records of variable length.
