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.

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

TL;DR: The unusual circumpolar distribution of krill reflects a balance between advection, migration, top–down and bottom–up processes, and the retention ofKrill in moderately productive oceanic habitats is a key factor in their high total production.
Journal ArticleDOI
An emperor penguin population estimate: the first global, synoptic survey of a species from space.
Peter T. Fretwell,Michelle A. LaRue,Paul Morin,Gerald L. Kooyman,Barbara Wienecke,Norman Ratcliffe,Adrian J. Fox,Andrew Fleming,Claire Porter,Phil Trathan +9 more
TL;DR: This work provides a comprehensive estimate of the total breeding population of emperor penguin populations that can be used in future population models and will provide a baseline for long-term research.
Journal ArticleDOI

David E. Smith,S. Shi,Robin A. Cullingford,Alastair G. Dawson,Sue Dawson,Callum R. Firth,Ian D L Foster,Peter T. Fretwell,Bruce Andrew Haggart,Lucy K. Holloway,David Long +10 more
TL;DR: In this paper, all currently known sites in the United Kingdom with evidence for the Holocene Storegga Slide tsunami are described and information on the altitude, distribution, stratigraphical context, age, particle size profile and microfossil characteristics of the deposits is presented.
