A broad Iceland plume associated with two phase transitions at the 660 km discontinuity: Constraints from receiver functions
"In spite of the fact that Iceland is frequently regarded as the archetypal example of mantle plumes, the existence, depth extent, origin, dimension and excess temperature of the hypothesized plume remain enigmatic and hotly debated. The controversy mostly originates from the limited vertical …

The origin of the assymetry in the Iceland hotspot along the Mid-Atlantic ridge from continental breakup to present-day
The Iceland hotspot has interacted asymmetrically with the Mid-Atlantic ridge since continental breakup, influencing the Reykjanes Ridge over a greater distance to the south than the Aegir and Kolbeinsey Ridges to the north. We investigate causes of this asymmetry with 3D numerical models that …

Generation of Buried Transient Landscapes and Residual Depth Anomalies
During Cenozoic times, the Icelandic plume has played a dominant role in controlling periodic uplift of oceanographic gateways across the North Atlantic Ocean. Five exquisitely preserved Paleogene buried landscapes are mapped on three-dimensional seismic reflection surveys from the Faroe-Shetland …
