Cryospheric events in the Arctic Ocean have been largely studied through the imprints of ice sheets, ice shelves and icebergs in the seafloor morphology and sediment stratigraphy. Subglacial morphologies have […]
Antarctic terrestrial ecosystems contribute a tiny proportion of the area of the continent and host an impoverished and often cryptic biota. In recent years it has been realized that much […]
The pre-last glacial maximum (LGM) Antarctic landscape with inherited preglacial topography (Sugden and Jamieson, 2018) was significantly overprinted by multiple ice advances and retreats driven by Milankovitch’s orbital forcing parameters […]
Changes in relative sea level (RSL) underpin the geomorphology and biology of the Antarctic coastal zone. They are a product of changes in regional ice dynamics, glacio-isostacy and eustatic sea […]
The Year of Polar Prediction in the Southern Hemisphere (YOPP-SH) had a Special Observing Period (SOP) that ran from November 16, 2018 to February 15, 2019, a period chosen to […]
Extreme precipitation events (EPEs) have a major impact across Arctic Fennoscandia (AF). Here we examine the spatial variability of seasonal 50-year trends in three EPEs across AF for 1968–2017, using […]
Profound changes in Arctic sea-ice, a growing desire to utilize the Arctic’s abundant natural resources, and the potential competitiveness of Arctic shipping routes, all provide for increased industry marine activity […]
When successive stages of an organism’s life-history overlap, conflicts and trade-offs can emerge due to competition among physiological pathways. For example, long periods of sustained locomotion in migrating birds are […]
Antarctic geothermal heat flow (GHF) affects the ice sheet temperature, determining how it slides and internally deforms, as well as the rheological behaviour of the lithosphere. However, GHF remains poorly […]
The effective size of a population (Ne), which determines its level of neutral variability, is a key evolutionary parameter. Ne can substantially depart from census sizes of present-day breeding populations […]
The flux of > 2 MeV electrons at geosynchronous orbit is used by space weather forecasters as a key indicator of enhanced risk of damage to spacecraft in low, medium […]
This chapter discusses recent changes in Antarctic climate. Changes in the atmospheric circulation modes that influence Antarctic climate, namely, the Southern Annular Mode (SAM), the Amundsen Sea Low (ASL), and […]
