A bilge pump from a shipwreck found in the Gulf of Mexico. Early explorations had mistaken this pump for a cannon.
Two squid attempt to mate in the Gulf of Mexico.
Salt “volcanoes” with oil, gas, and brine being expelled. Here, less-dense oil migrated upwards to the seafloor through faults in the subsurface, passing through areas of brine still trapped below. As the brine-covered oil droplets escaped the seafloor and travelled upward towards the surface of the Gulf, their denser layers of brine were shed, falling back to the seafloor. Droplet by droplet, the salt slowly built up a cone around the oil seep. The brown mineral on the volcanoes and the seafloor is unknown.
