What Did Scientists Learn About The Sea Floor

By the 1920s the coast and geodetic survey an ancestor of the national oceanic and atmospheric administration s national ocean service was using sonar to map deep water.

What did scientists learn about the sea floor. This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century. Marine life and exploration on the ocean floor. Many of these newly discovered species live deep on the ocean floor in unique habitats that depend on plate movement underwater volcanoes and cold water seeps.

The super continent was broken apart in part by sea floor spreading scientists discovered that sea floor spreading continues to move the continents sea floor spreading can be measured using. Far taller and deeper than any landforms found on the continents. The first modern breakthrough in sea floor mapping came with the use of underwater sound projectors called sonar which was first used in world war i.

But our knowledge of the deep seas is changing because of information from satellites. They ve also measured the vibration using seismometers on land but had not yet successfully measured it at the sea floor which could help scientists better quantify the sources of the vibrations. Before scientists invented sonar many people believed the ocean floor was a completely flat surface.

Since we ve been working here in the indian ocean now for the last 15 years we ve discovered that large parts of the sea floor have no crust dick says the mantel s directly exposed to the sea floor the scientists hope to continue drilling for another 100 meters during their current expedition. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. New species are discovered in the ocean each year by marine biologists and other ocean scientists.
