Our aim was to estimate the population of emperor penguins (Aptenodytes fosteri) using a single synoptic survey. We examined the whole continental coastline of Antarctica using a combination of medium […]
Bathymetric charts are essential for modeling oceanic processes, yet, in remote areas, direct measurements of seafloor depth are often scarce. It is possible to augment sparse depth soundings with dense […]
The objective of this work is to evaluate the potential of reduced order models to reproduce the extreme event and predictability characteristics of higher dimensional dynamical systems. A nonlinear toy […]
Despite the loss of CryoSat, ESA’s first Earth opportunity mission, during its launch sequence in Oct 2005 ESA have been fortunate enough to have acquired, processed to Level 1b and […]
Observations were made of ocean microstructure and horizontal currents adjacent to Brunt Ice Shelf in the southeastern Weddell Sea. Periods of in situ supercooled water extending as deep as 65 […]
Invasive alien species are among the primary causes of biodiversity change globally, with the risks thereof broadly understood for most regions of the world. They are similarly thought to be […]
During the heroic age of Antarctic exploration, snow blindness was a common problem, but not all the descriptions of it lit the modern view of the disease, and some of […]
The Antarctic ozone hole of 2010 is reviewed from a variety of perspectives, making use of various data and analyses. Based on total column ozone metrics, the 2010 ozone hole […]
Physiological mechanisms mediating carryover effects, wherein events or activities occurring in one season, habitat, or life-history stage affect important processes in subsequent life-history stages, are largely unknown. The mechanism most […]
Lineages undergoing rapid radiations provide exceptional opportunities for studying speciation and adaptation, but also represent a challenge for molecular systematics because retention of ancestral polymorphisms and the occurrence of hybridization […]
This chapter contains sections titled: Introduction Subglacial Lake Sediments as Archives of Paleoenvironmental Change Direct Information from Surface Exposures and Sediment Cores Acquired from Subglacial Paleolakes Sedimentary Processes in Subglacial […]
Lubchenco challenges scientists to: ‘‘ address the most urgent needs of society, in proportion to their importance; communicate their knowledge and understanding widely in order to inform decisions of individuals […]
