Deep sea submersibles help get research from the ocean floor.
On the ocean floor
A deep sea basin is a depression of the sea floor more or less equidimensional in form and of variable extent.
you can float in it ans=d it is a deep sea
The abyssal plain.
Deep-sea organisms have been difficult to study because the ocean floor is hard to get to.
No they are not.

Ocean ridges and deep-sea trenches support the theory of sea floor spreading through the process of plate tectonics. At ocean ridges, new oceanic crust is formed as magma rises and solidifies, pushing the existing crust apart. Deep-sea trenches are areas where old oceanic crust is being subducted back into the mantle, completing the cycle of sea floor spreading. This continuous movement of crust at ridges and trenches provides evidence for the theory of sea floor spreading and the movement of tectonic plates.
Deep sea floor samples can be taken using a variety of methods. The use of sonar machines and robotic mechanisms are what is typically used these days. These machines are used to extract various materials from the sea to be examined and studied.
