"The CTD rosette was provided by the Knorr Shipboard Science Support Group
(SSSG) and was prepared for initial deployment by the SSSG representative on
our cruise, Catie Graver. The system was a SBE9+ CTD with a depth limit of
6000m. The investigators used the dual SBE3T/SBE4C sensor system for
temperature and conductivity. The rosette was also equipped with a SBE43
oxygen sensor, a Benthos/Datasonics PSA-916 altimeter, a Wet Labs FLNTURTD
combination fluorometer and turbidity sensor, and a WetLabs C-star
transmissometer (operating at a wavelength of 660 nm with a 25cm pathlength).
For hydrocasts less than 1000m deep, the investigators attached a Biospherical
Instruments QSP-200L4S underwater PAR sensor. This sensor was linked to a
surface PAR sensor on the ship (QSR-240).";

"Transformations of dissolved organic matter (DOM) in the deep ocean have profound impacts on the global carbon cycle due to the sequestration of carbon dioxide (CO2) away from the atmosphere.  Although research has been conducted on the high molecular weight component of this material, the same cannot be said for low molecular weight DOM because the needed analytical techniques have not been available to determine its composition and reactivity.
In recent years, a research team at Woods Hole Oceanographic Institution has acquired the necessary analytical capability. As such, in this project, they will carry out the first systematic survey of deep ocean DOM in the western Atlantic Ocean to characterize the low molecular weight fraction of DOM in southward flowing North Atlantic Deep Water (NADW), northward flowing Antarctic Bottom Water (AABW), and Antarctic Intermediate Water (AAIW).  Using ultrahigh resolution mass spectrometry and multi-stage fragmentation coupled to liquid chromatography, the scientists will determine the spatial variability in the composition of DOM along the flow path of the water masses, as well as assess the source water, transport, and surface processes that contribute to temporal changes in DOM composition.  These results will be augmented with structural elucidation and quantitative assays of unique marker compounds for each water mass.  Results will provide important insights into the biogeochemical reactions that govern DOM dynamics in the deep ocean.";

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.
