I was quite sure that there would be a very simple, non-Atlantean, explanation for the grid patterns. The real question now is why the news organizations couldn’t be bothered to get the opinion of any professional who works with such images regularly.

I work with satellite imagery and these patterns appear where the image is very low contrast (I could show you an example from the waters around Manhattan). The “unenhanced images” are already stretched from the raw data (which looks black)The patterns are produced by noise in the sensor, exacerbated by compression/expansion and contrast stretching during post-processing. I actually spend quite a lot of time trying to get rid of them…
