Dataset of velocity

Velocity data measured by ADCP are opened on the FTP
(ftp://ftp.ocean.hiroshima-u.ac.jp/pub/wpadcp) and WWW
(http://www.ocean.hiroshima-u.ac.jp) server, after processed on the line
described in a separate document. These data are archived in datasets. In
this document, the name, form and format of these dataset are described in
detail.
----------------------------------------------------------------------------

1. Name

One dataset contains velocity data for one track of a cruise. Here
``cruise'' presents a cruise of round trip from Japan to Japan. ``Track''
means a ship track from one port to another port during this cruise. For
example, if the ship stops by three ports, Port A, Port B and Port C before
comes back to Japan, we distinguish the following four tracks: the track
from Japan to port A, the track from port A to port B, the track from port B
to Port C, and the track from Port C to Japan. These tracks are labeled as
A, B, C and D in order.

Each cruise is identified by a number 001, 002, 003, from the first cruise
in order.

The name of a dataset begins with the word ``w'', which is named after the
initial letter of ``Western Pacific ADCP Program''. This ``w'' is followed
by the year and month of a measurement, and a cruise identification number.
The extension of a file is the label of a track and a version of data
processing.

For example, we have two datasets, w9701002.a10
w9702002.b10 for the second cruise. Here ``9701'' (``9702'') shows that this
data was measured in January (February) 1997, and ``002'' shows the cruise
identification number. ``a'' (``b'') in the extension indicates the ship
track from Japan to Australia, (from Australia to Japan), and ``10''
represents that the version of the data processing is 1.0.
----------------------------------------------------------------------------

2. Form

The dataset is composed of many lines of ASCII codes, where each line ends
up by new-line code (hexadecimal code 0A) as in Unix-like operating system.
Each data file is compressed by GNU gzip archiver. So you can read it by a
text editor after you decompress it.
----------------------------------------------------------------------------

3. Format

The dataset contains header data and N sets of velocity data at each
location on the track. Here N is the total number of the data, which is
recorded in the header data. Table I and II show the format of header data
and velocity data, respectively.

In these tables, Format is described by the format statement of FORTRAN77.
That is, In means n digits of integer, and An means n characters. Fn.m is a
floating point, the total length of which is n and the digit below the point
is m . 1X means single space.
