The central Arctic Ocean sediment record: current progress in moving from a litho- to a chronostratigraphy
In recent years there has arisen a major controversy surrounding the ages of the sediments recovered from the central Arctic Ocean. Earlier interpretations (Steuerwald et al. 1968; Clark 1970. 1971; Hunkins et al. 1971; Clark et al. 1980) inferred that the rates were very low, and of the order of 0....

In recent years there has arisen a major controversy surrounding the ages of the sediments recovered from the central Arctic Ocean. Earlier interpretations (Steuerwald et al. 1968; Clark 1970. 1971; Hunkins et al. 1971; Clark et al. 1980) inferred that the rates were very low, and of the order of 0.2 to 0.005 cm/ 1,000 years. These ages were based primarily upon published interpretations of the paleomagnetic polarity records of central Arctic Ocean sediments. These interpretations have been challenged by Sejrup et al.
