Seems simple to me, if the world is ninety percent water, a crucial part of preserving our environment should be the monitoring and maintaining of our oceans. However, due to the massive volume of water and inclement weather conditions, it’s almost nearly impossible to do this year round. But a possible solution may be in sight.
Enter the robotic floats that collect argo data from the ocean’s heat. First used in the Indian Ocean by Australia in ’99, there are now about 2,100 currently in use, with another 900 or so ready to dive in.
According to the Commonwealth Scientific and Industrial Research Organisation (CSIRO), the floats are less-compressible than seawater and therefore drift at depth. By pumping fluid from inside the float to an external bladder, they’re able to rise to the surface. When the float needs to dive, the fluid is drawn back inside, making the gadget denser than the seawater surrounding it. These floats can be deployed from ships or aircraft.
The Jason altimetry satellite is used with the argo system to keep track of the ocean’s shape as it changes due to heat and currents. Argo is also sponsored by the World Climate Research Programme’s Climate Variability and Predictability project (CLIVAR) and by the Global Ocean Data Assimilation Experiment (GODAE). It is a pilot project of the Global Ocean Observing System (GOOS).
Once we’re able to understand (and hopefully even predict) the various changes occurring in our oceans and atmosphere, we’ll be better equipped to make the necessary strategies to save our planet.
