Some people suggest the sudden massive drop in water level would be a large bubble of released methane or gas of some sort coming up underneath or very near the buoy, but it seems unlikely.
But it was not only the sudden change in water depth off New Jersey Coast, on the same day satellites from the NASA Space Weather Prediction Center detected a complete collapse of earth's magnetosphere.
Earth’s Magnetosphere what protect us from solar winds and radiation just vanished around the entire planet for two hours.
The two strange events come 2 days after a huge anomaly covered New York and the upper East Coast, registered by MIMIC on April 21, 2016. See our article Be Aware - Huge anomaly Appears Over New York and Upper East Coast.
Just coincidence or is this another proof of weather warfare?
