Each profile consists of up to 1, 000 measurements of temperature and salinity at varying depths.
Existing stresses on fish stocks could be worsened as water temperature, salinity and entire ecosystems change.
The data collected will be ocean temperature and salinity, crucial factors in both ocean circulation and climate.
Before Argo, the temperature and salinity of the subsurface oceans could only be measured from ships or fixed point moorings.
Liquid Robotics, the US company behind the project, collected data about the Pacific Ocean's temperature, salinity and ecosystem from the drone.
Argo takes the pulse of the ocean, collecting and distributing temperature and salinity observations from a fleet of 3000 underwater robots.
Argo is a global fleet of 3000 data collection ships that collect high-quality temperature and salinity profiles from the upper 2000m of the ice-free global ocean.
Teams participating in yacht races have collected temperature and salinity data on their route for scientific purposes and the private sector is also getting involved.
We can suspect, for example, that the UK might suffer due to shutting down the Gulf Stream, but there would be thousands of other changes caused by the change in temperature, salinity, and acidity levels.
FORBES: What Would Be The Best Place To Live If The Polar Ice Caps Melt?
Today Argo provides the first-ever global-scale, all-weather subsurface observations of the oceans, an unprecedented dataset for researchers studying the temperature, salinity, and circulation of the global oceans and how these change over periods ranging from days to decades.
In addition to a sea floor mapping project, the researchers will make chemical analyses of water samples that will help them determine the temperature, salinity and composition of a strong circumpolar current that flows around the boundary of the Arctic Ocean.

Today, hundreds of floats deployed under the Global Ocean Observing System (GOOS), coordinated by UNESCO and largely supported by the Japan Meteorological Agency (JMA) and Japan Agency for Marine-Earth Science and Technology (JAMSTEC), are used to measure ocean temperature, salinity and tsunami risk.
The first Argo floats were deployed in late 1999, and by November 2012, Argo had collected its millionth profile of temperature and salinity, twice the number obtained by research vessels during all of the 20th century. 120, 000 new profiles are collected every year, at the impressive rate of 1 profile approximately every 4 minutes.
It is a collaborative partnership of more than 30 nations from all continents, all working together to provide a seamless global array of over 3, 000 profiling floats moving up and down in the water column from the sea surface to 2, 000 meters and measuring temperature, salinity, and depth during every ascent to the sea surface.
"Every half-metre, it takes a measurement of the temperature and the salinity, " said Mr Hadow.
They mounted sensors on white whales to measure the salinity and temperature patterns of the fjord during its initial winter freezing.
In an oxygen-free (anaerobic) environment at a certain temperature, pH and salinity, the bacteria can produce a toxin that in very small amounts can cause life-threatening paralysis.
FORBES: Prisoners Making Hooch: What Could Possibly Go Wrong?
Extremophiles comprise principally bacteria, which have the remarkable ability to thrive in conditions that would be hazardous to other lifeforms - extremes of temperature, radiation, salinity, and metal toxicity.

They carefully dictate everything from the size of the crabs caught to the salinity and temperature of the water they are stored in until they arrive nightly at the restaurant.
In this highly competitive and sometimes harsh environment, marine species have had to develop strategies for survival, such as resistance to the toxicity, extreme temperature, hyper-salinity and pressure that characterize the deep seabed.
Crossing expanses never remotely surveyed, they will gather 2.25 million data points about salinity, water temperature, waves, weather, fluorescence and dissolved oxygen.
