TL;DR: Bedmap2 as discussed by the authors is a suite of gridded products describing surface elevation, ice-thickness and the seafloor and subglacial bed elevation of the Antarctic south of 60° S. In particular, the Bedmap2 ice thickness grid is made from 25 million measurements, over two orders of magnitude more than were used in Bedmap1.
Journal ArticleDOI

TL;DR: This record of the Neogene reveals cooling of the Arctic that was synchronous with the expansion of Greenland ice and East Antarctic ice and supporting arguments for bipolar symmetry in climate change.
Journal ArticleDOI
Deep glacial troughs and stabilizing ridges unveiled beneath the margins of the Antarctic ice sheet

TL;DR: In this paper, a high-resolution and physically based description of Antarctica bed topography using mass conservation is presented, revealing previously unknown basal features with major implications for glacier response to climate change.
Journal ArticleDOI
Magmatic and amagmatic seafloor generation at the ultraslow-spreading Gakkel ridge, Arctic Ocean
Peter J. Michael,Charles H. Langmuir,Henry J. B. Dick,Jonathan E. Snow,Steven L. Goldstein,David W. Graham,Kerstin Lehnert,Gregory J. Kurras,Wilfried Jokat,Richard Mühe,H. N. Edmonds +10 more
TL;DR: Observations of the Gakkel ridge demonstrate that the extent of mantle melting is not a simple function of spreading rate: mantle temperatures at depth or mantle chemistry (or both) must vary significantly along-axis.
Journal ArticleDOI
Timing and geometry of early Gondwana breakup
TL;DR: In this paper, aeromagnetic data collected along the East Antarctic coast during five seasons were used to provide new constraints on the timing and geometry of the early Gondwana break-up.
