INSTRUCTIONS FOR ACCESSING FILES FROM THE NODC 
SHIPBOARD ADCP ANONYMOUS FTP AREA
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Connect by Anonymous FTP to a SUN Workstation 
at the University of Hawaii by typing


       ftp kapau.soest.hawaii.edu

In response to 'Name' enter 'anonymous' 

In response to 'Password' enter your own home userid@address

Then type 
            cd /pub/adcp
            get read.me
            bye   (optionally exit to view read.me)


Shipboard ADCP Center - How to Obtain Data
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The shipboard ADCP data are available as two data types: 

   densely-sampled set (~10 Mbyte per cruise-month) as CODAS binary block
   files of the currents and ancillary data at the interval with which the data were
   recorded and processed, and 
   an ASCII standard subset of the currents, ship speed, and transducer
   temperature at hourly and 10 m depth intervals. 

For each cruise, a metadata file is prepared for summarizing specifics about the
instrumentation, cruise activities, processing, and calibration.

An inventory browser is available via anonymous ftp for SUN and SGI workstations
and for IBM-PC computers using DOS. The browser is downloaded and executed on
your machine. Within the WWW home page, one may also access the Online
Inventory system. From queries of the database or from the inventory lists, one may
send us a list of SAC IDs for specifying desired cruises, or grab the data yourself
from the Online Database system. 

The densely_sampled set is available as binary CODAS block files. CODAS
software is compatible to most workstations and IBM-PC compatible computers and
is provided if necessary. CODAS data extraction subset software and manual are
geared to data users. The complete CODAS software and manual are geared to data
collectors and processors and includes steps on how to load ping files (data from
DAS), process, calibrate, and apply navigation data. Both software sets are available
via anonymous ftp or paper mail and include a utility for translation of the block
files between machines with different binary numbering conventions. A complete
ASCII dump of the CODAS block files (about 50 Mbytes per cruise-month) can also
be provided. 

The standard subset and metadata files are maintained online in an anonymous ftp
area and are available free of charge. The format of the standard subset is ASCII. 

Both data types, metadata files, inventories, and cruise tracks can be obtained via
conventional storage media (diskettes or DAT, eXabyte, or magnetic tapes) for a fee.
The densely-sampled data set may also be made available on anonymous ftp on a case
by case basis. In general, NODC products and services are provided on a cost
recovery basis. Researchers who submit data to the NODC, however, are eligible to
receive NODC data on exchange. 

All orders from non-Federal customers must be prepaid, unless the customer meets
strict criteria for a waiver of this requirement. Turn around time is about two to
three weeks. Prepayment may be made by:

   Check (in U.S. funds drawn on a bank in the United States, made payable to
   "U.S. Department of Commerce/NOAA/NODC") 
   Money order 
   Credit card (VISA and MasterCard only) 

Purchase orders can be accepted from non-Federal customers only with prior
approval from the NODC. If this authorization is not obtained beforehand, an
additional charge of $24 will be added to the total charges for that order.

   Magnetic tapes 
      9-track (1600 bpi), standard length (2400 ft.) ........ $79 
      9-track (6250 bpi), standard length (2400 ft.) ........ $93
