Bedrock geology in New England submarine canyons

... negative anomaly observed further to the north (Figures 3, 11). The irregular positive anomaly is bounded further to the west by a prominent north northeast-south southwest fault parallel to the main margin fault. The data suggest that deeply subsided continental crust continues some 50 km to the we ...

Following roughly 10 million years of generally cool conditions, the climate gradually warmed and reached another warm maximum at circa 15 Ma (beginning of the middle Miocene). Cooling that eventually led to the Pleistocene ice ages began with another m ...
