The global Argo array is made of about 3,000 free-drifting floats measuring temperature and salinity (along with possibly other parameters such as oxygen) of the upper ocean.
The North Atlantic Argo Regional Center (NA-ARC) focuses on profiles located in North Atlantic Ocean North of 20S, in the Mediterranean and Arctic Seas. The NA-ARC web API provides a set of services with many functions to retrieve information about Argo profiles and floats in the North Atlantic Ocean. Those information are based or computed from the NA-ARC database updated daily. The API uses RESTful calls and responses are formatted in JSON.
