J-Anomaly Ridge
The J-Anomaly Ridge is a bathymetric feature in the North Atlantic Ocean, extending southwest from the eastern end of the Grand Banks of Newfoundland.[1] It has a length of about 400 km (250 mi) and rises 1,200 m (3,900 ft) above the general level of the Sohm Abyssal Plain.[2] The ridge consists of anomalously thick oceanic crust that formed as a result of a major volcanic pulse during the Cretaceous.[3]
