How many operational Argo floats are there today?
Currently, there are roughly 4000 floats producing 100,000+ temperature/salinity profiles per year.
Why does Argo float?
All Argo floats carry sensors to measure the temperature and salinity of the ocean as they vary with depth, but an increasing number of floats also carry other sensors, such as for measuring dissolved oxygen and ultimately other variables of biological and chemical interest such as chlorophyll, nutrients and pH.
How does an Argo float work?
What does an Argo float do? The standard Argo float mission is a 10-day cycle, with most of the float’s time spent drifting along with deep ocean currents, followed by taking a series of measurements as it moves back up (profiles) to the ocean surface.
How does an Argo float transmit data?
Data transmission systems As the float ascends, a series of pressure, temperature, salinity and other measurements are made and stored on board the float. These are transmitted to satellites when the float reaches the surface.
What are the major differences between moored buoys and Argo floats?
While moored buoys operate at its deployed location, Argo floats drift and measure temperature and salinity at different locations in ocean.
What are Argo profiles?
Argo is an international program that calls for the deployment of 3,000 free drifting profiling floats, distributed over the global oceans, which will measure the temperature and salinity in the upper 2,000m of the ocean providing 100,000 T/S profiles and reference velocity measurements per year.
Where are ARGOs made?
Where are ARGOs made? The Argo is an amphibious ATV created in Kitchener, Ont., by Ontario Drive & Gear (ODG) in 1967. ODG designs and manufactures power transmissions and gears for the North American market.
What data do Argo floats collect?
The data that Argo collects describes the temperature and salinity of the water and some of the floats measure other properties that describe the biology/chemistry of the ocean.
How do Argo buoys measure oceanic salinity?
An Argo float recently surfaced in the Atlantic Ocean to transmit temperature and salinity measurements from over a mile deep. Approximately every 10 days, an Argo float dives about 1.2 miles deep, drifts with the ocean currents, and then surfaces to transmit data in real-time via satellite.
How does Argo work?
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.

What engines does Argo use?
Powered by the Briggs & Stratton, 656 cc twin cylinder I/C engine, the 6 Twin replaced the Argo 6 Heavy Duty. Following the success of this model, ODG introduced the Argo 8 Twin as a smooth running successor to the Argo 8 Heavy Duty.
When did the first Argo float come out?
The first Argo floats were deployed in 2000 and the array consisted of a combination of P-ALACE and PROVOR floats as part of the international co-operative effort.
How does the density of an Argo float change?
The density of any object is given by its mass divided by its volume. The Argo float keeps its mass constant, but by altering its volume, it changes its density. To do this, mineral oil is forced out of the float’s pressure case and expands a rubber bladder at the bottom end of the float.
What kind of sensors are on Argo floats?
Initially, the array provided CTD profile data and subsurface ocean current data but continued development means that the current technology of newly deployed floats includes a growing range of sensors including, for example, oxygen probes, CO2, nitrate, chlorophyll and backscatter sensors.
How does the antenna work on an Argo float?
The different models of Argo floats made around the world have differences in both hardware and software, but mostly operate in a similar fashion. Antenna – All Argo floats are topped with an antenna that allows them to communicate with satellites to send their data, obtain a position and find out if there is a new mission.
