The data uploaded to satellites is collected while the Argo Float travels from
2,000m underwater
to the surface. The data describes a ‘profile’ of the ocean. That means it shows the changing temperature and salinity as the Argo Float rises to the surface.
How deep can Argo floats go?
Currently, there are roughly 4000 floats producing 100,000+ temperature/salinity profiles per year. The core floats go as deep as 2000 m and the Deep Argo Mission floats go
all the way down to 6000 m
.
What data do Argo floats collect?
What are its aims? 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.
What does the Argo float measure?
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
.
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
.
Why Argo floats are important?
What is Argo? Argo is a global array of 3,800 free-drifting profiling floats that
measures the temperature and salinity of the upper 2000 m of the ocean
. … These sensors allow scientists, for the first time to monitor decadal changes in the ocean ecosystem.
Do all Argos float?
The Argo fleet consists of
almost 4000 drifting “Argo
floats” (as profiling floats used by the Argo program are often called) deployed worldwide. Each float weighs 20–30 kg. … Both the standard Argo floats and the 4 satellites launched so far to monitor changing sea-level all operate on a 10-day duty cycle.
How long do ARGO floats last?
| Where is the Argo Float? Approximate time | Day 2-9 at 1,000m 9 days | going down 2 hours | at 2,000m 2 hours | Day 10 going up 8 hours |

What do floats measure?
ALACE floats take
ocean measurements of temperature
when they are floating at depth. PALACE and SOLO floats can measure temperature plus salinity (conductivity) and pressure (depth), and take these measurements as they rise to the surface.
What is a CTD sensor?
A CTD — an acronym for Conductivity, Temperature, and Depth — is
the primary tool for determining essential physical properties of sea water
.
How does Argo float work?
– When an Argo float is launched,
its bladder is inflated to keep it floating at the surface
. … After a while the bladder deflates again, and the float sinks to 2000m. There oil is pumped into the bladder; the float becomes buoyant and rises, measuring temperature and salinity on the way up.
How does temperature change as the Argo float sinks deeper into the ocean?
As the ocean takes up more heat,
the temperature is rising and the volume of the water is increasing
, raising sea level across the globe.
Where are ARGO floats?
The Argo Program
One of roughly 3,000 Argo floats deployed
in ice-free areas of the world’s oceans
that profile ocean temperature and salinity. These floats dramatically reduce the amount of time and cost of gathering these data by research ships using traditional over-the-side methods of ocean observations.
What does Argo stand for?
| Acronym Definition | ARGO Association of Remote Gambling Operators (now Remote Gambling Association) | ARGO Array for Real-Time Geostrophic Oceanography | ARGO Advanced Reciprocating Gait Orthosis | ARGO Automatic Ranging Grid Overlay |

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 is the meaning of Argo?
:
a large former constellation in the southern hemisphere lying principally between Canis Major and the Southern Cross
that is now divided into the constellations of Puppis, Vela, and Carina.
