> Argo is an international collaboration that collects high-quality
> temperature and salinity profiles from the upper 2000m of the ice-free
> global ocean and currents from intermediate depths.

> The data come from battery-powered autonomous floats that spend most of
> their life drifting at depth where they are stabilised by being neutrally
> buoyant at the "parking depth" pressure by having a density equal to the
> ambient pressure and a compressibility that is less than that of sea
> water.
>
> At present there are three models of profiling float used extensively in
> Argo.
> All work in a similar fashion but differ somewhat in their design
> characteristics.
>
> At typically 10-day intervals, the floats pump fluid into an external
> bladder and rise to the surface over about 6 hours while measuring
> temperature and salinity.
>
> Satellites determine the position of the floats when they surface, and
> receive the data transmitted by the floats. The bladder then deflates and
> the float returns to its original density and sinks to drift until the
> cycle is repeated. Floats are designed to make about 150 such cycles.

Actually, Linux/Unix *IS* used for *real* work (NYSE, NASA...); Windows is used for amateur work.
