The genomic revolution has provided researchers with the opportunity to address broadreaching questions in ecology, evolution and conservation with greater power and precision than ever before. It is nowpossible to […]
Accurate geolocation of ionospheric backscatter measured by the Super Dual Auroral Radar Network (SuperDARN) high‐frequency radars is critical for the integrity of polar ionospheric convection maps, which involve combining SuperDARN […]
Debris‐covered glaciers are ubiquitous in the Himalaya, and supraglacial debris significantly alters how glaciers respond to climate forcing. Estimating debris thickness at the glacier scale, however, remains a challenge. This […]
The inability of organisms to cope in changing environments poses a major threat to their survival. Rising carbon dioxide concentrations, recently exceeding 400 μatm, are rapidly warming and acidifying our […]
Over the past 3.5 million years, there have been several intervals when climate conditions were warmer than during the preindustrial Holocene. Although past intervals of warming were forced differently than […]
While observed mesospheric polar nitric acid enhancements have been attributed to energetic particle precipitation through ion cluster chemistry in the past, this phenomenon is not reproduced in current whole-atmosphere chemistry-climate […]
The abundance and flux of acantharian cysts were recorded for a period of 12 months from December 2012 to 2013 in a sediment trap deployed at 1500 m in the […]
There is a growing search for less invasive methods while studying the diet of Antarctic animals in the wild. Therefore, we compared the diet of gentoo penguins from stomach contents […]
Following more than 200 Ma of subduction of Pacific oceanic crust beneath the west coast of the Antarctic Peninsula, subduction ceased by a series of ridge crest-trench collisions. However, magmatism […]
Regression functions of total length on carapace length and total length on removed carapace length were calculated for Antarctic krill Euphausia superba Dana for those classes of sex and maturity […]
1 Earlier work with albatrosses led to the hypothesis that a critical element influencing ovarian development each year is whether the ovary responds to rising gonadotrophin secretion by secreting progesterone […]
