EXPOCODE

A14

(Includes Country Code, Ship Code, Expedition Designation/Leg) Due to the number of cruises involved, a unique identifier
is required for all WOCE cruises. To provide such identification, please use the following procedure to form the requisite
Mnemonic.
The first 4 characters are the US National Oceanographic Data
Center (NODC) country ship code. The US NODC country codes
are defined in Table 3.6. Note that the country code is
associated with the country of origin for the ship. That
may be different from the country actually conducting the
cruise. The US NODC ship code can normally be obtained
from OCEANIC. If you cannot obtain the ship code from there,
the WHPO can provide the proper code for you.
The country-ship code is followed by up to an 8 character
expedition name or cruise number and the leg (default = 1)
of the cruise is appended after the _ (underscore) symbol. The
expedition name or cruise number is normally assigned by the ship
operator and their conventions should be used. For example,
German cruises are designated by a number and leg while French
cruises are usually given a name. Thus, a name should not be given
in the EXPOCODE for a German cruise. Further, some countries
designate their cruises by a number but that number is reset
to 1 every year. In such cases the year should be included
with the cruise number, for example, the 9th cruise of the R/V
A. von Humboldt in 1991 would be given cruise number 991 in the
EXPOCODE to ensure uniqueness.
An alias for the cruise may be fiven in the -.DOC file and will
be retained with the netadata for the cruise. For formatting
reasons, the expedition name is limited toeight (8) characters.
Therefore, if necessary, the expedition name should be abbreviated to
8 characters for the EXPOCODE, but will be carried full length with
the metadata. The EXPOCODE is also used in the water sample (-.SEA)
and -.CTD files to tie these files to the -.SUM file in order to
uniquely identify the cruise or expedition in those files.

The WHP Section designator. Section designations were originally assigned in the WOCE Implementation Plan. However, many sections
have been added or modified since then. If you have a question about the section designation for the work that you are
doing, please contact the WHPO.
Many one-time sections are broken into segments that are often done by different invesigators on different ships. To account for this the WHPO
frequently assigns suffixes to the section designator to distinguish
among these segments. The same is true for some repeat sections as well. If a suffix has been assigned to your segment (this information is available
from the WHPO or via OCEANIC) it would be appreciated if that identification is included in the WHP-ID. Also, in order for sort routines in a database to work correctly it is necessary that all section numbers be the same length, which requires a leading zero for single digit sections. That is, section P1 sould be written as P01, AR5, is AR05, and so on.
If stations are taken on a cruise that are not associated with a WHP section then this field should be left blank in the -.SUM file.

Station Numbers
|
Right
|
1X, A5
|
Whenever possible the station numbering should be continuous for each section, i.e., station numbers should not be reset at the beginning of each leg of long WHP cruises carried out with multiple legs. Repeat and time series cruises often use the same station number(s) on sequential cruises and that presents no difficulties as long as each cruise is given a unique EXPOCODE. In order to guage the accuracy of the station position we ask that position, time, and the uncorrected depth be given in the -.SUM file for the beginning, bottom, and end of every hydrographic cast. That allows an estimate of the ship drift during the station and whether or not the ship drifted across significant topography during the station.

Cast Numbers and Type
|
Right
|
4X, I3, 2X, A3
|
Cast Numbers and Type (right justify)The cast numbers are
sequential and preferably numbered from 1 to n at each
station position. Every over-the-side operation or discrete
sampling at a station is assigned a sequential cast number.
The cast type is a three-character description, for
example, ROSette water samples plus CTD (ROS), Large Volume
Samples (LVS); CTD only (CTD) including fast fish CTD
launches; etc. A complete list of cast types is given in
Table3.5. If any other abbreviations for cast types are
necessary an explanation and definition of such
abbreviations must be included in the cruise report (.DOC
file) and in the text file accompanying the CTD and water
sample data file.
If a station is reoccupied during the
same cruise, and the same station number is used, the cast
numbers should increment upward from the last cast number
at the same station. In no case should two records in the
.SUM file contain the same STNNBR and CASTNO on the same
cruise.

Date

This field consists of the number of the month, day, and the last two digits of the year (MMDDYY).
The date should be zero filled, that is, 050793, not 5 793. Note that this system probably differs
from the system used in your country. We request the use of this method solely for the sake of
uniformity within a diverse community. Should be zero padded.

For most over
the side operations, and all hydrographic casts, the recorded time and position should indicate
the beginning (BE), bottom (BO or MR), and completion (EN) of the cast. Bottom depths should
also be recorded at each of these times. If additional time or position codes are used they
should be defined in the chief scientist's cruise report.

Position is to be recorded
three (3) times during each hydrographic cast, at the
beginning, bottom, and end, together with the time the
position was taken, as described above, and the depth, as
described below. Best available positioning technology
should be employed and the technique used should be entered
as illustrated in Table3.5. Codes for all known navigation
methods are defined in Table2.3. Positions should be
recorded as (D)DD MM.MM X, where X is N or S for latitude
and E or W for longitude, for example, 2710.11S,
11752.43E should be recorded as 27 10.11 S 117 52.43 E.
Only ASCII characters recognized by FORTRAN-77 should be
used in the file, for example, a (degree) symbol is not
recognized and should not be included. The ASCII character
set is given in Appendix F.

Uncorrected Bottom Depth
|
Right
|
1X, I5.5
|
The uncorrected acoustic sounding in meters
assuming a sound velocity of 1,500m/s should be noted for
each time and position recorded. For most casts the depth
and position should be recorded at the beginning, bottom,
and end of the cast. Corrections should be made only for
the depth of the acoustic transducer beneath the ocean
surface, or if the echo sounder assumed a sound velocity
different than 1500 m/s. The WHPO will provide a corrected
water depth for the station, based on Carter Tables, in the
Data Reports and the .SUM file available from SAC.
If the
depth reading is questionable, some estimate of uncertainty
should be given in the bathymetry section of the cruise
report (.DOC file).
The WHPO adds a corrected depth column
adjacent to the uncorrected depth before sending the final
.SUM file to the SAC.
