Argo Float Data(Subset)

Argo is an international program that collects information from inside the ocean using a fleet of robotic instruments that drift with the ocean currents and move up and down between the surface and a mid-water level. Each instrument (float) spends almost all its life below the surface. The name Argo was chosen because the array of floats works in partnership with the Jason earth observing satellites that measure the shape of the ocean surface. (In Greek mythology Jason sailed on his ship the Argo in search of the golden fleece).

These data were collected and made freely available by the International Argo Program and the national programs that contribute to it. (, The Argo Program is part of the Global Ocean Observing System.

The general Argo DOI is below.

Argo (2000). Argo float data and metadata from Global Data Assembly Centre (Argo GDAC). SEANOE.

If you used data from a particular month, please add the month key to the end of the DOI url to make it reproducible. The key is comprised of the hashtag symbol (#) and then numbers. For example, the key for August 2020 is 76230. The citation would look like:

Argo (2020). Argo float data and metadata from Global Data Assembly Centre (Argo GDAC) – Snapshot of Argo GDAC of August 2020. SEANOE.

ArgoVis citation

Argovis API was used to parse through and get to the datasets, you can cite argovis using the following

Argo Float data tables

Argo float dataset has been parsed into a small subset of about 20,000 feature collections flattened into a single collection with over 12.1 million features with total distinct argo float count at 866. The argo float property variables and GEE property names are listed below

Property GEE Property Property Type
Platform ID pid integer
Instrument Type inst_typ integer
date date integer
date added date_added integer
profile number profile_number string
maximum pressure max_pres float
pres_max_for_TEMP pmax_temp float
pres_min_for_TEMP pmin_temp float
pres_max_for_PSAL pmax_psal float
pres_min_for_PSAL pmin_psal float
