"Shipboard acoustic Doppler current profiler data collected during the
Integrated Acoustic and Trawl Surveys of Pacific Hake.
Processing by:  Stephen Pierce, Oregon State University
(P. M. Kosro also performed some processing steps in the 1998 case)
Date:  16 August 2006
Data quality: Good in general
Missing or poor-quality data have been omitted.

This dataset has a simple simple version of observed velocities, useful
for most purposes.  The complete data sets with all configuration and
processing details and diagnostic data (e.g. error velocity, AGC,
spectral width) are available from the NODC Joint Archive for Shipboard
ADCP, or by request from S. Pierce.

Processing steps included:  editing of the data using various
diagnostics, calibration of the phase and amplitude errors of the
ADCP/navigation/gyrocompass system by covariability analysis between
currents and ship velocity, reference layer velocity smoothing, and
final production of earth-referenced velocities.  For more details
regarding methods, see:  Pierce et al. (2000), DSR II 47, 811-829.

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data),
via a specially formed URL. tabledap uses the OPeNDAP Data Access Protocol (DAP) and its selection constraints.

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file
type for the response.

(easy) You can get data by using the dataset's Data Access Form or Subset form.
They make the URL for you.
(easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
(not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by
hand or with a computer program or script.

Tabledap request URLs must be in the form
http://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
http://coastwatch.pfeg.noaa.gov/erddap/tabledap/erdGlobecBottle.htmlTable?longitude,latitude,time,bottle_posn,temperature1&time>=2002-08-17T00:00:00Z&time<=2002-08-19T20:18:00Z
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of
constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
