Mapping the Ocean Floor

This is an old Bathymetric map. A Bathymetric map is a map of the ocean floor. Hydrologists and Oceanographers use this for learning how the ocean floor looks.

This ship uses a machine called Sonar.Sonar: Sound Navigation and Ranging. It sends PINGS to show the depth with the formula.

The mid-ocean ridge is a long cut down the middle of the ocean. It's where two plates slide apart (divergent boundary). Convection currents rise in the mantle beneath the oceanic crust and create magma when this uplifting occurs. Then new ocean floor is formed.

There are all types of animals in the sea. Some are Sharks, Jellyfish, and Clownfish. The ocean is diverse and animals make it their home at our pleasure.

There are many features on the Seafloor. A Continental Slope is a steep slope extends to the ocean, an Abyssal Plain is flat land between 3,500 & 6,000, and a Trench is a long, narrow depression. A Seamount is a mountain on the ocean floor and is an island when it hits the surface, a Island is any piece of land surrounded by water, and a Guyot is an isolated volcanic mountain with a flat top.

Mapping the Ocean Floor

Bathymetry is the study of the ocean floor. This takes a formula for Sonar; Time x 1520m/sec = depth of the ocean. Sonar uses PINGs: sounds like ''PING''.
