Age of the Ocean Floor: A Digital Data Set for the Labrador Sea and Western North Atlantic

Walter R. Roest, R. Dietmar Müller, Jacob Verhoef


A digital grid of ocean floor ages was constructed from a combination of magnetic anomaly identifications and recent plate kinematic models of the North Atlantic and Labrador Sea. Comparing large gridded geophysical data sets with these gridded age values is a powerful means of studying the variation of geophysical parameters with lithospheric age, and the dynamic processes in the Earth. The data set from the western North Atlantic and Labrador Sea shows the dependence on age of bathymetry, depth-to-basement and gravity.
