    String summary 
"The SmartBay Observatory in Galway Bay is an underwater observatory which uses cameras, probes 
and sensors to permit continuous and remote live underwater monitoring. It was installed in 2015 on the seafloor 1.5km off the coast of 
Spiddal, Co. Galway, Ireland at a depth of 20-25m. Underwater observatories allow ocean researchers unique real-time access to monitor 
ongoing changes in the marine environment. The Galway Bay Observatory is an important contribution by Ireland to the growing global 
network of real-time data capture systems deployed in the ocean. Data relating to the marine environment at the Galway Observatory site is 
transferred in real-time through a fibre optic telecommunications cable to the Marine Institute headquarters and then made publically 
available on the internet. The data includes a live video stream, the depth of the observatory node, the water temperature and salinity, 
and estimates of the chlorophyll and turbidity levels in the water which give an indication of the volume of phytoplankton and other 
particles, such as sediment, in the water. Maintenance take place on the observatory every 18 to 24 months. A Teledyne RDI Workhorse 
Broadband 600KHz acoustic Doppler current profiler (ADCP ) is mounted on the observatory infrastructure. It is approximately two metres 
above the seabed, looking up towards the sea surface. Data are collected every minute for 1.0m depth bins from approx. 1 metre above the 
instrument to the surface. Data are collected in RDI's PD0 binary format (more information is available from the link: 
http://spiddal.marine.ie/data.html#adcp). The .PD0 raw files are processed as they are collected and the real time values for the Near 
Surface and Mid Water Current Speeds and Directions are extracted. The extracted values are displayed in near-real-time on 
smartbay.marine.ie. The processed data is also provided via an ERDDAP data server allowing the data to be downloaded in a range of open 
formats. The sensor is deployed on the EMSO Smartbay Cable End Equipment Node in Galway Bay in approx. 25m depth of water.";

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.

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.
