String summary "This dataset contains the processed water temperature, salinity (derived from conductivity) and pressure data from CTD instruments from a pilot deep water mooring deployed at a site (15.52 degrees West, 52.999 degrees North) in the South Rockall Trough close to the M6 met-ocean buoy. Data from the buoy is not available for this time period as the buoy broke loose shortly after it was deployed. The pilot sub-surface mooring was deployed in October 2018, then retrieved in May 2019 and consisted of an array of 10 Sea-Bird SBE 37 CTD sensors at a series of fixed depths below the surface (500m, 625m, 750m, 1000m, 1250m, 1500m, 1750m, 2000m, 2500m, 3000m). This subsurface mooring pilot deployment collected data providing a short intra-annual time-series (~8 months) and complements the annual Marine Institute oceanographic survey to the South Rockall Trough, which has taken place since 2004 (weather conditions permitting). The CTD sensors were fully calibrated by Sea-Bird in Germany both pre and post deployment. Additional sensors on the mooring include ADCP (Acoustic Doppler current profiler) sensors to measure ocean currents and direction, this data is stored in a different file. The mooring was built, deployed and managed by the Marine Institute through discretionary Marine Institute funding and loan of sensors from the National University of Ireland Galway (NUIG). At present there are no operational or project funds available to maintain a continuous series of moorings at the South Rockall Trough location but when logistics and infrastructure are available future deployments may take place. The data from the deployment help understand the variability in the water column not visible at the surface and provide context to CTD profile data collected at 12-18 month resolution in the South Rockall Trough. These data are vital in understanding the likely impact of future ocean climate scenarios on key marine sectors as well as understanding possible impacts on ecosystem in the North East Atlantic Ocean. The raw temperature, salinity and pressure data has been checked for any sensor drifts and interpolated onto a high resolution (20 dbar) vertical grid (420 - 3060 dbar) following McCarthy et al. (2015) (https://doi.org/10.1016/j.pocean.2014.10.006) . This is achieved by integrating EN4 data derived (for the period August 2018- May 2019) temperature and salinity gradients between adjacent instruments.";

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.
