Crustal growth of the Antarctic Peninsula by accretion, magmatism and extension
Read more of: Crustal growth of the Antarctic Peninsula by accretion, magmatism and extensionA subduction-accretion model incorporating new geophysical data is presented to explain the geology of the Antarctic Peninsula from late Palaeozoic to Cenozoic time. According to the model, the peninsula consists […]

Automated detection of basal icequakes and discrimination from surface crevassing
Read more of: Automated detection of basal icequakes and discrimination from surface crevassingIcequakes at or near the bed of a glacier have the potential to allow us to investigate theinteraction of ice with the underlying till or bedrock. Understanding this interaction is […]
