Things You Can Do With Your Graphs

Well, you can do anything you want with your graphs, of course. But some things you might not have considered are:

Web page authors can embed a graph of the latest data in a web page using HTML <img> tags.
Anyone can use ERDDAPs Slide Sorter to build a personal web page that displays graphs with the latest data (or other images or HTML content), each in its own, draggable slide.

The main goals of this cruise were as follows: (1) Recover six moorings, including one sound source, and three trawl resistant bottom mounts concentrated in the upper De Soto Canyon. Instruments recovered have collected a years worth of: temperature, conductivity, pressure and current data. (2) Occupy CTD stations at the mooring locations and along the western edge of De Soto Canyon, collecting measurements of: temperature, conductivity, pressure, dissolved oxygen, turbidity (amount of suspended particles in the water), optical properties of water (transmittance or attenuation of incident radiation), and chlorophyll -A. (3) Sample water from the western edge of De Soto Canyon, up to and including mooring M6, in order to better understand the cholorophyll max. Collected samples will be analyzed for methane concentration, oxygen concentration, nutrients, cell microscopy, microbes (for DNA/RNA work) and particulate organic carbon (for carbon isotope work). (4) Acquire shipboard Acoustic Doppler Current Profiler (ADCP) data (75kHz, 150kHz, and 300 kHz), from surface to bottom, for the duration of the cruise. This dataset contains CTD data from this cruise.";

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 (external link)

Data Access Protocol (DAP) (external link)

and its selection constraints (external link)

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
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
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.
