Acoustic sub-bottom profiler surveys on the northeast Antarctic Peninsula shelf indicate that parts of the seabed are underlain by an acoustically transparent layer that is thin on the inner shelf and becomes thicker and more extensive towards the outer shelf. Sedimentological and geophysical data are combined to construct a bed model where streaming ice flow, by both deformation and basal sliding, took place within cross-shelf troughs. The model suggests only limited deformation contributed to fast flow on the inner shelf, i.e. in the onset zone of ice streaming, where the bed was predominantly underlain by a stiff till. Thus, fast ice flow in this area might have been by basal sliding, with deformation confined to discontinuous patches of soft till <40 cm thick. Towards the middle and outer shelf, extensive, thick sequences of soft till suggest a change in the dominant subglacial process towards widespread deformation. This downstream change from basal sliding to subglacial deformation is manifest in the transition from stiff-till dominance to soft-till dominance, while a downstream increase in ice flow velocity is evident from the complex geomorphic imprint on the inner shelf evolving to the more restricted set of bedforms on the outer shelf.

Oxford has been crowned the world’s best university for the third successive year, according to the latest Times Higher Education World University Rankings.The University beat second-placed Cambridge to the title, ensuring that Oxford remains the only UK University ever to top the international rankings.The new league table for 2019 was unveiled at the World Academic Summit in Singapore this afternoon, with Oxford first among the 1258 universities assessed worldwide.Vice Chancellor of Oxford University, Louise Richardson, said: “We’re deeply gratified by this result but also delighted to see how strongly British and other European universities have performed.“As we in the UK face the great unknown that is Brexit we look forward to ever deeper cooperation with colleagues abroad. It has never been more important that we engage internationally in furtherance of the themes of this year’s World Academic Summit in Singapore – advancing knowledge, driving the economy, and recognising the transformative power of academic research.”Chief Knowledge Officer at Times Higher Education, Phil Baty, said: “Oxford has once again been confirmed as the world’s number one university – the third consecutive year in the top position.“You cannot lead the World University Rankings without an outstanding performance right across our full range of performance indicators, covering teaching excellence, research power and impact, industry relations and international outlook.“Oxford stands out across the board, but what sets it apart from the top-ranked schools below it, primarily from the US, is its exceptionally international focus. Oxford thrives, not just due to strong levels of research funding, and a remarkably intimate teaching environment, but primarily due to the talent on its campus – and there’s no doubt Oxford is a magnet for talent globally, attracting the brightest and the best students and faculty from all over the world.”The full rankings can be found here.
