    "description": "Argo is a global array of 3,000 free-drifting profiling floats that measures the temperature and salinity of the upper 2000 m of the ocean. This provides continuous monitoring of the temperature, salinity, and velocity of the upper ocean, with  data being made publicly available within hours after collection. The array provides 100,000 temperature/salinity profiles and velocity measurements per year distributed over the global oceans at an average of 3-degree spacing. Some floats provide additional bio-geo parameters such as oxygen or chlorophyll. Data collected by Argo floats are publically available in near real-time via the Global Data Assembly Centers (GDACs) in Brest (France) and Monterey (California) after an automated quality control (QC), and in scientifically quality controlled form, delayed mode data, via the GDACs within six months of collection.",

BioGeoChemical data are included no matter the QC flag and Deep data under 2000 db is included if the QC flag is '2' for pressure and temperature and '3' for salinity.
