Improving ocean information and forecasting
Argos is a unique worldwide location and data collection system dedicated to studying and protecting the environment.
Argos offers ocean data telemetry services for a broad spectrum of applications including ocean modeling, moored buoy monitoring and more.
Collecting oceanographic data in-situ
Oceanographers regularly use Argos to collect in-situ observation data. In all of the world’s oceans, drifting and moored buoys and profiling floats transmit environmental data via the Argos system for operational programs such as the World Weather Watch (WWW) of the World Meteorological Organization (WMO). Argos is an essential tool of the Global Ocean Observing System (GOOS) for collecting oceanographic measurements and their geographical location, particularly for the Argo program, the Ship Observation Team (SOT) program and the Data Buoy Cooperation Panel (DBCP).
Locating instruments at sea
Argos transmitters, which are both robust and energy efficient, are used to locate expensive oceanographic instruments. Due to its global coverage, its accurate Doppler positioning (to within 250m) and tools such as the goniometer for retrieval in the field, Argos is the ideal satellite system for geolocating and retrieving instruments at sea.
Mapping surface currents
Due to its Doppler location capability, Argos is the most widely used global satellite system for mapping surface currents. With or without GPS, Surface Velocity Program (SVP) drifting buoys accurately measure the movements of water masses between the surface and a depth of 15 meters. These in-situ measurements are then fed into numerical models to improve ocean current forecasting.
