This guy pointing to the GOM around the Texas - Mexico border area has reminded me that there was a huge oil spill around there back in the 1980s I think. I remember seeing it as part of a video on the BP oil spill.* Basically it's largely forgotten now but it was Petro... (Mexican State Oil) and it was in shallow water, within sight of land.

My point being that the HAARP activity down there might be aimed at heating up the water which I assume has replaced all the oil that has been taken out over the years. Hopefully someone knows more.

* A historical background segment I think.
