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).

Citation¶

These data were collected and made freely available by the International Argo Program and the national programs that contribute to it. (https://argo.ucsd.edu, https://www.ocean-ops.org). 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. https://doi.org/10.17882/42182

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:

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
Temperature	temp	float
Salinity	psal	float
Pressure	pres	float
