Geoengineering Test Quietly Launches Salt Crystals into Atmosphere

[ArMaP]

The aerosols will be using sea salt which is a natural substance albeit if they are injecting more sea salt into the environment that may be an issue or are they using existing sea salt from the ocean, whereby with this process it will simply be put back into the same environment (?)

By definition, sea salt comes from the sea, so I suppose it wouldn't make much of a difference. Also, the amounts are a drop in the ocean (almost literally), so even if they are getting sea salt from the Atlantic and dropping it in the Pacific I don't see a problem with that.
