String summary
"The hydrographic sampling performed by OOI-CGSN (the Ocean Observatories Initiative - Coastal and Global Scale Nodes) as part of each Array turn represents a significant collection of valuable physical, chemical, and biological information. In addition to the CTD, collected hydrographic data include discrete oxygen, salinity, nutrient (nitrate, nitrite, silicate, phosphate, ammonium), chlorophyll, and carbon system measurements. These data serve several important functions. First, they are necessary for the calibration and evaluation of the moored instrumentation at each Array. Furthermore, the annual (Global) or biannual (Coastal) collection of data at the same locations provides a unique time series of a large set of water properties following established community standards and methods, independent of its association with the OOI moorings.
The analyses of collected water samples for the parameters listed above are performed by a number of outside labs on behalf of OOI-CGSN. Consequently, the water sampling data for a given cruise is distributed among a number of different files. The Discrete Sampling Summary integrates the related CTD, metadata, and discrete water sample data into a single file. Additionally, it synthesizes qualitative and quantitative information about the quality of a measurement into data quality flags for each associated parameter which follow WOCE-standards.
The final product per cruise is the Discrete Sampling Summary spreadsheet which contains the metadata, CTD data and discrete water sample data into a single spreadsheet with data quality flags. For the original sample data files per cruise, navigate into the “Water_Sampling” folder within each cruise in OOI's Raw Data Archive (see Related Dataset). This BCO-DMO dataset combines the Summary spreadsheets for all cruises together into a single tabular data file.
The Coastal Pioneer Mid Atlantic Bight (MAB) Array is located off the coast of North Carolina, starting about 25 km east of Nags Head. The MAB continental shelf north of Cape Hatteras is characterized by a persistent equator-ward current originating from the north, a shelfbreak front separating shelf and slope waters, distributed buoyancy inputs from rivers, variable wind forcing, and intermittent offshore forcing by Gulf Stream meanders. The Pioneer MAB Array is designed to resolve transport processes and ecosystem dynamics in the vicinity of the shelfbreak front, which is a region of complex oceanographic dynamics, intermittent mesoscale variability, and enhanced biological productivity.
The MAB array began sampling in 2024 and consists of 10 moorings at 7 sites arranged in a T-shape spanning 50 km east/west on its cross-shelf axis and 50 km north/south along the continental shelf, centered near the shelf-break front. However, note that the first discrete samples collected from the MAB array site came from the engineering test cruises At-Sea Test 3 & At-Sea Test 4 (AR 78) in 2023.";

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.
