Ages for ocean floor between the oldest identified magnetic anomalies and continental crust are interpolated by geological estimates of the ages of passive continental margin segments.

Age of sea floor map.

The data is from four companion digital models of the age age uncertainty spreading rates and spreading asymmetries of the world s ocean basins. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. A digital age map of the ocean floor. Sio reference series 93 30 scripps institution of oceanography.

An international scientific team recently published a new map of the ocean floor based on earth s gravity field and it is a particularly useful tool. Because of this correlation between age and subduction potential very little ocean floor is older than 125 million years and almost none of it is older than 200 million years. Therefore seafloor dating isn t that useful for studying plate motions beyond the cretaceous. Measurements of the thickness of marine sediments and absolute age determinations of such bottom material have provided additional evidence for seafloor spreading.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. Most new crus t forms at these mid ocean spreading ridges. Scientists use the magnetic polarity of the sea floor to determine the age. New sea floor map for google earth january 13 2016 in late 2014 we had a look at a map of the ocean floor published by the scripps institution of oceanography university of california san diego.

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. The oldest sediments so far recovered by a variety of methods including coring dredging and deep sea drilling date only to the jurassic period not exceeding about 200 million years in age. Very little of the sea floor is older than 150 million years. The age spreading rate and asymmetry at each grid node is determined by linear interpolation between adjacent seafloor isochrons in the direction of spreading.

A marine gravity map of the north atlantic ocean red dots show locations of earthquakes with magnitude 5 5 and they highlight the present day location of the seafloor spreading ridges and. Note that the youngest seafloor ages are found at the mid ocean spreading ridges where new rock is constantly coming up from under the crust to heal the rifts formed as tectonic plates move away from one another. The data are described in a data and analysis note in the journal of geophysical research 1997 entitled digital isochrons of the world s ocean floor.
