The 2019 dolphin die-off in the Gulf of Mexico.

In 2019, more than 260 dolphins stranded themselves across Louisiana, Mississippi, Alabama and the Florida panhandle from the beginning of February to June. This was approximately three-times higher than the historical average. In Mississippi alone, 126 dolphins died on the coastline. There was a line of meteor airbursts across the Caribbean during this period. It started on February 1 with a fireball that produced an airburst with equivalent energy to 1,400,000 kg/TNT. It was travelling south to north over Cuba into the Gulf of Mexico. On April 14 another airburst struck off the coast of Haiti with an energy of 100,000 kg/TNT. Then a third happened off the coast of Mississippi/Louisiana on May 4 with an energy equal to 79,000 kg/TNT. To cap it off on June 22, to bookend these incidents, a further massive airburst occurred in the Caribbean between Venezuela and Puerto Rico that had the energy of 6,000,000 kg of TNT. The four airbursts were almost in a straight line across the Gulf of Mexico. The cetacean strandings were blamed on rain.
