String comment
"##Limitations:
Purpose: The Moving Vessel Profiler (MVP) records temperature, salinity, sound velocity, fluorescence, dissolved oxygen, and transmittance in the water column. Vertical profiles provide information on prevailing physical oceanic conditions during CCGS Amundsen expeditions, aiding in biological, chemical, and physical samplings. They also record parameters for studying physical oceanographic processes in the Canadian Arctic Ocean, including water column structure, water mass characteristics, and oceanic circulation. While data collection extends beyond the Canadian Arctic border, the primary focus is on the Canadian Arctic Ocean.

String summary
"The Canadian research icebreaker CCGS Amundsen is equipped with a Moving Vessel Profiler (MVP), a versatile instrument designed to collect both shallow and deep water data sets without the need to halt the vessel. During transects, multiple consecutive casts of the MVP are conducted, facilitating the collection of data on the physical and chemical characteristics of the water column.
The MVP was deployed during the Amundsen scientific expeditions, spanning the summer and fall of 2004 to 2024, with the exception of 2005, 2006, and 2019. Data was unavailable for 2012 due to the ship undergoing maintenance. The system components underwent slight variations throughout the year, typically comprising a Micro CTD (Temperature, Conductivity, and Pressure), a Micro DO2 (Dissolved Oxygen), a Micro SV (Sound Velocity and Pressure), an ECOFLO (Fluorescence), and a C-Star (Transmittance) probe.
The MVP data were meticulously corrected and controlled by comparing them to CTD-Rosette and thermosalinograph (TSG) data whenever feasible. Comprehensive metadata and reports are provided to support the information presented and serve as documentation regarding the data processing methodologies.";

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.
