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.

Physical, biogeochemical and bio-optical products derived from measurements acquired by the autonomous BGC-Argo profiling float WMO 2903797. This dataset provides products derived from 0-2000 m profiles acquired by the autonomous BGC-Argo float WMO 2903797 (National Research Council- CNR, Institute of Marine Sciences - ISMAR) across the Ionian Sea (Mediterranean Sea), since November 2023. This float is equipped with a set of sensors for measuring essential ocean, climate and biodiversity variables.  The data were collected and made freely available by the International Argo Program and the national programs that contribute to it (https://argo.ucsd.edu, https://www.ocean-ops.org). The Argo Program is part of the Global Ocean Observing System. All data collected are also publicly available in near real-time via the Global Data Assembly Center (Global Data Assembly Centres (GDAC)) - Coriolis (France) after automated quality control (www.seanoe.org/data/00311/42182). The dataset of derived products contains, for each profile acquired by the BGC-Argo float from 0 to 2000-m depth, a Network Common Data Format (NetCDF) file containing the following quantities: the Mixed layer depth, the Euphotic Depth and profiles of the Potential Density and the Particulate Organic Carbon concentration (POC). POC is computed from quality-controlled optical particulate backscattering measurements at the wavelength of 700 nm and quality-controlled chlorophyll-a concentration according to Koestner et al. (2022, doi:10.3389/fmars.2022.941950).  Photosynthetically Available Radiation (PAR) is quality-controlled following the algorithm described in La Forgia and Organelli (2025, doi:10.1002/lom3.10701).

Before the computation of the euphotic depth, PAR profiles have been quality-controlled for cloud effects and wave focusing according to Organelli et al. (2016, doi:10.1175/JTECH-D-15-0193.1). The dataset of derived products is continuously updated in near-real-time as soon as new profiles are available.

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").
