The ocean floor, like dry land masses, features a wide variety of terrain. And as with dry land, features that truly stand out are mountains — in the ocean they are called seamounts. And as on land, they can be created by tectonic plates pushing against one another, or by volcanos erupting. Currently, just one-fourth of the sea floor has been mapped, which means that no one knows how many seamounts exist, or where they might be. This can be a problem for submarines — twice U.S. submarines have collided with seamounts, putting such vehicles and their crew at risk. But not knowing where the seamounts are located presents another problem. It prevents oceanographers from creating models depicting the flow of oceanwater around the world.
In this new effort, the research team set themselves the task of discovering and mapping as many seamounts as possible, and to do it, they used data from radar satellites. Such satellites cannot actually see the seamounts, of course, instead they measure the altitude of the sea surface, which changes due to changes in gravitational pull related to seafloor topography; an effect known as sea mounding. In so doing, they found 19,000 previously unknown seamounts.
In their paper, the team notes that other important reasons for mapping the ocean floor include things like assisting with sea-floor mining efforts — seamounts harbor vast amounts of rare-earth minerals. More complete seamount maps would also help geologists better map the planet's tectonic plates and geomagnetic field. Also, some seamounts provide a habitant for a vast array of marine life.
But most importantly, they have a very strong impact on deep-sea ocean flow. As currents run into seamounts, they are pushed upward, carrying colder water with them, and mix in unknown ways. Mapping such currents has become more important as the oceans absorb more heat and carbon dioxide from the atmosphere and freshwater melt, due to ongoing climate change.

Great white shark washes up on South Carolina beach in rare, unusual stranding
The 10-foot-long female stopped breathing after locals tried several times to coax her back into the water. The cause of the animal's death remains a mystery. A great white shark washed up on...The environment changes in the world oceans, not to mentions he changes in in EF changes through the traffic in so called defense strategies, changing the frequencies of mammalian species in our ocean
And this just the tip of the issue, what about the pollution, with other substances, that have been negligently tipped in the oceans of the world.
Human waste, pharmaceutical drugs, in wastewater dropped into the oceans, plastics, the list is endless.
This would be a wake up call, not only are nations being destroyed, our oceans are being destroyed.
The frogs are not boiling, they are being crucified alive, and nobody says a word, because the agenda of the day is the LBQT plus issue, rightly so, children, body and mind mutilated.
But we live on a planet of many aspects of creation, and if, as some have voiced written about we are the most intelligent species (that is an issue for another debate).
We have lost our way, when we in such hubris, that some sections of society, think that they can mimic, life on this beautiful world we live and walk upon, and because it does not serve, their purpose (and lord knows what what that ultimate purpose is ). Want to create another version or reality of creation.
The absolute hubris beggars belief, to destroy, the creation, of the universe, that has taken billions of years to develop and evolve.
The only word that comes to my mind in the English language is blasphemy, and due to the limitations of the English language it's concepts and ideology, it does not do it justice.
