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. This CTD
(Conductivity, Temperature, Depth) and Oxygen Dataset comprises of the raw data that is collected from the
Galway Observatory site using an Idronaut Ocean-Seven 304 plus Conductivity-Temperature-Depth (CTD) sensor
probe. The sensor measures the temperature and conductivity of the seawater. The conductivity is used to
calculate an estimate of the salinity. The pressure exerted by the seawater above is used to calculate the depth
of the sensor, and these parameters are also used to estimate the speed of sound within the sea. The Ocean-Seven
304 Plus CTD has also been equipped with a polarographic IDRONAUT dissolved oxygen sensor which measure the
dissolved oxygen concentration of the seawater. The sensor is deployed on the EMSO Smartbay Cable End Equipment
Node in Galway Bay in approx. 25m depth of water.";

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.
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.
