The Sea Floor Profiles And Scales

Seafloor mapping also called seabed imaging is the measurement of water depth of a given body of water bathymetric measurements are conducted with various methods from sonar and lidar techniques to buoys and satellite altimetry various methods have advantages and disadvantages and the specific method used depends upon the scale of the area under study financial means desired measurement.

The sea floor profiles and scales.

The red line shows the sea floor depths and the green is the geoid anomaly. Global sea floor topography from satellite altimetry and ship depth soundings. As upwelling of magma continues the plates continue to diverge a process known as seafloor spreading. Ocean literacy fundamental concept.

To map the seafloor research vessels cross the ocean making sonar profiles along carefully navigated parallel courses called transect lines. The ohaus vx series is a portable low profile floor platform and indicator scale package. Long wavelength large anomalies 100 meters from the ellipsoid over thousands of km due to mass differences in the mantle many of which reflect older plate tectonics and remnants of subducted plates. An ocean basin s size shape and features such as islands trenches mid ocean ridges rift valleys vary due to the movement of earth s lithospheric plates.

Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.

The landscape of the seafloor would best be described as. It is the ideal solution for freight consolidators forwarders processing plants resellers shipping and receiving departments as well as startup businesses. Plate tectonics plate tectonics seafloor spreading. After many profiles are made they can be assembled to create complex maps or three dimensional models of the seafloor by filling the spaces between the profiles using computer models or modeling.

The earth has one big ocean with many features. These age data also allow the rate of seafloor spreading to be. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. A a featureless plain b a smooth descent with the deepest portions farthest from land c similar in rock type sediment thickness and erosional processes to those found on the land d containing ridges trenches seamounts and other features different from those found on land.
