Morphology of the Northeastern Atlantic and Labrador Sea
Abstract
Recent surveys by the US Naval Oceanographic Office have added greatly to the knowledge of the primary and secondary processes which have created the present morphology of the northeastern Atlantic and Labrador Sea.
Primary processes are directly attributed to the generation of oceanic crust at the axis of the Mid-Oceanic Ridge. Shifting orientations of the axis have produced three differently oriented discrete stripes of oceanic crust since 60 million years ago. Evidence suggests a yet older axis may have been responsible for the opening of the Labrador Sea-Bay of Biscay in the early Mesozoic. Secondary processes have and are still modifying the igneous crust. The prime agent is a strong thermo-haline circulation which is piling up sediment into great plumes in some areas and eroding in other locales.- Publication:
