Iceberg plough marks are found at all depths in the Barents Sea, down to 450 m. Keels of present-day icebergs observed in the region rarely exceed 100 m. Hence, most ploughmarks found at greater depths are relict. Plough mark degradation is dependent on a number of factors, such as sedimentation rate, degree of benthic activity and strength of bottom currents. Therefore, age determination of plough marks based on morphological characteristics can be dubious.
