Argo is a system for observing temperature, salinity, and currents in the Earth's oceans which has been operational since the early 2000s. The real-time data it provides is used in climate and oceanographic research. A special research interest is to quantify the ocean heat content (OHC).
Argo consists of a fleet of almost 4000 drifting profiling floats deployed worldwide. Each Argo float weighs 20–30 kg. Profiling floats are commonly used in oceanography and become "Argo floats" only when they are deployed in conformity with the Argo data policy. In most cases probes drift at a depth of 1000 metres (the so-called parking depth) and, every 10 days, by changing their buoyancy, dive to a depth of 2000 metres and then move to the sea-surface, measuring conductivity and temperature profiles as well as pressure. From these, salinity and density can be calculated. Seawater density is important in determining large-scale motions in the ocean. Average current velocities at 1000 metres are directly measured by the distance and direction a float drifts while parked at that depth, which is determined by GPS or Argos system positions at the surface. The data are transmitted to shore via satellite, and are freely available to everyone, without restrictions.
In Greek mythology, Argo (/ˈɑːrɡoʊ/; in Greek: Ἀργώ, meaning 'swift') was the ship on which Jason and the Argonauts sailed from Iolcos to retrieve the Golden Fleece. She was named after her builder, Argus.
Argo was constructed by the shipwright Argus, and its crew were specially protected by the goddess Hera. The best source for the myth is the Argonautica by Apollonius Rhodius. According to a variety of sources of the legend, Argo was said to have been planned or constructed with the help of Athena. According to other legends she contained in her prow a magical piece of timber from the sacred forest of Dodona, which could speak and render prophecies. After the successful journey, Argo was consecrated to Poseidon in the Isthmus of Corinth. She was then translated into the sky and turned into the constellation of Argo Navis.
Several authors of antiquity (Apollonius Rhodius, Pliny,Philostephanus) discussed the hypothetical shape of the ship. Generally she was imagined like a Greek warship, a galley, and authors hypothesized that she was the first ship of this type that had gone out on a high-sea voyage.

Argo is a global array of more than 3,500 free-drifting profiling floats that measure the upper two thousand meters of the ocean. The Argo array allows continuous monitoring of the temperature, salinity, and velocity of the upper ocean, with all data being relayed and made publicly available within hours after collection. While the present Argo array provides observations of the upper ocean, this is only about one-half of the total oceanic volume. The need for a deep-ocean component of Argo has been recognized through support for instrumentation development and first pilot deployments. Deep Argo floats will profile the ocean from the surface to 6,000 below to give us an understanding of deep ocean temperature and salinity changes, something we know very little about and which is importan...
The ARGO Float program at NOAA's Atlantic Oceanographic and Meteorological Laboratory (AOML) in Miami, Fl. More then 3000 drifting instruments circle collecting scientific measurements to help improve weather forecasting and hurricane predictions.
The device shown in this video is an autonomous robot called an ARGO float. This robot looks at the top 1000 meters, over 3000 feet, for different characteristics of the water. The sensors on this float read the temperature, salinity, oxygen and nitrate in the water. ARGO (Array of Real-time Geostrophic Oceanography) floats cover the oceans to get a global view of the ocean in near real-time. Over 3500 floats are currently deployed around the world's ocean giving a constant status on the temperature and status. Each one is completely self-sufficient and drifts for 5-7 years collecting data and sending it in via satellite communication. The key part of the ARGO platform is that, all of the data the array brings in is completely free and public data. This means anyone, even you, can get...
The Argo stop-motion animation aims to inspire children (and adults) to engage with marine science. It is quirky, fun and informative at the same time. The animation explains what an Argo float is, how it operates and how all this data helps us to understand the ocean circulation and climate. Oceanographers have deployed more than 3500 robotic profiling floats into the global oceans as part of the international Argo program over the past 15 years. Argo floats measure water properties such as temperature, salinity and pressure from the surface to a depth of two kilometres. Floats can change their buoyancy by pumping oil into and out of an external bladder, which allows them to sink, drift with the ocean currents and measure data as they rise to the surface. The floats send their data and l...
Argo Program and Argo float description with Dr. Susan Wijffels (Physical oceanographer at CSIRO). Argo profilers to study and understand the sea change.
The oceans influence everyone and everything on earth, from climate to crops. Until recently we knew little about complex oceanic systems, but now the science of our seas is undergoing a revolution. Earth Reporter Dr Susan Wijffels, one of the world's top oceanographers, works at the forefront of scientific discovery. We follow Susan and her colleagues as they collect and interpret data from an array of hundreds of free floating oceanic robots - known as Argo floats.The Argo project is delivering new data on ocean temperature and salinity to help scientists better understand the planet's incredibly complex climate system.

This video walks through the Docker container created by the Marine Institute’s Data Management team which enables users to quickly expose data from a series of Argo floats to the World Wide Web using NOAA’s Erddap software. More information about the Argo project can be found at http://www.argo.ucsd.edu/, and details of the Marine Institute’s involvement are available at http://www.marine.ie/Home/site-area/areas-activity/oceanography/euro-argo. The Docker container can be found on GitHub at https://github.com/IrishMarineInstitute/docker-argo-erddap.

Video footage from CalCOFI shows the Jan. 24, 2013 deployment of a Deep SOLO prototype. The instrument could soon complement floats used in the global Argo network, an array of 3,500 instruments in the world's oceans that afford scientists an unprecedented record of basic conditions in all ocean basins simultaneously. Deep SOLO uses a similar pump to Argo floats, but is housed in a glass sphere rather than in an aluminum cylinder in order to be able to dive to depths as great as 6,000 meters (19,700 feet). It is designed by Jeff Sherman, Russ Davis, and David Black of the Scripps Instrument Development Group. Upper-ocean Argo floats measure seasonal, interannual, and decadal variability, while the deep array will be more focused on decadal signals, said Argo scientist Dean Roemmich.
Эта визуализация показывает положение (перемещение) буёв ARGO во времени (вы же в курсе что такое буи ARGO? если нет то вам сюда http://www.oceanographers.ru/index.php?option=com_content&task;=view&id;=96&Itemid;=122) Когда буй над водой линии светлее, когда под водой, темнее. Буи ARGO измеряют солёность и температуру воды, а также скорость и направление течения.
