What are the bathymetric features?

Bathymetric features such as the continental shelf and seamounts interact with ocean currents and winds to produce regions of upwelling, where nutrient-rich waters are brought to the surface. This nutrient-rich water supports high levels of primary production by phytoplankton, which in turn attracts larger organisms.

What bathymetric features are associated with convergent boundaries?

Along some segments of convergent boundaries that are highly active as source regions of great earthquakes and tsunamis, there exists a profusion of ridges, scarps, deep-sea marine terraces or perched basins.

What Earth features are located on plate boundaries?

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.

What does bathymetry tell us about plate tectonics?

A bathymetric map shows what the ocean floor would look like if all the water drained floor would look like if all the water drained out. Bathymetric data from the oceans is used to help us understand plate tectonics. These “rafts” are called lithospheric plates.

What are bathymetric techniques?

Bathymetric surveys allow us to measure the depth of a water body as well as map the underwater features of a water body. Multiple methods can be used for bathymetric surveys including multi-beam and single-beam surveys, ADCPs, sub-bottom profilers, and the Ecomapper Autonomous Underwater Vehicle.

What happens to oceanic plates at convergent boundaries?

At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

What are the 5 types of plate boundaries?

What are the major plate tectonic boundaries?

  • Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
  • Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.
  • Transform: shearing; plates slide past each other. Strike-slip motion.

Why is bathymetry important?

Bathymetric maps can help scientists determine where fish and other marine life feed, live, and breed. Bathymetric data is also used to create maps of coral habitats to assist in conservation and monitoring.
