The impact of observed changes in air temperature and precipitation from 1969 to 2013 and climate projections for 2050 and 2080 at Ny-Ålesund, an arctic research station on Spitzbergen Island in the Svalbard Archipelago on snow hydrological processes, were analyzed using snow accumulation and ablation algorithms in the physically based Cold Regions Hydrological Modelling platform (CRHM). The clima ...

Abstract:
... A detailed study of gravel-size sedimentary clasts in the ANDRILL-2A (AND-2A) drill core reveals distinct changes in provenance and allows reconstructions to be produced of the paleo ice flow in the McMurdo Sound region (Ross Sea) from the Early Miocene to the Holocene. The sedimentary clasts in AND-2A are divided into seven distinct petrofacies. A comparison of these with potential source rocks f ...

Abstract:
... Comparisons between historical and contemporary photographs of coral reef flats from the inshore Great Barrier Reef (GBR) have been cited by various authors and agencies as evidence of reef degradation since European settlement and have been presented as proof of widespread reef decline. The diminished condition is inferred from reduced live coral cover and structural diversity depicted in the con ...

Abstract:
... The Northern Bay of Bengal (NBoB) is a globally important region for deep-sea organic matter (OM) deposition due to massive fluvial discharge from the Ganges-Brahmaputra-Meghna (G-B-M) rivers and moderate to high surface productivity. Previous studies have focused on carbon burial in turbiditic sediments of the Bengal Fan. However, little is known about the storage of carbon in pelagic and hemipel ...

Abstract:
... Following worldwide bans and restrictions on the use of many persistent organic pollutants (POPs) from the late 1970s, their regional and global distributions have become governed increasingly by phase partitioning between environmental reservoirs, such as air, water, soil, vegetation and ice, where POPs accumulated during the original applications. Presently, further transport occurs within the a ...

Under the moderate emission scenario of the IPCC's Representative Concentration Pathway 4.5 (RCP4.5), the predicted sea-level variation is spatially non-uniform. The most remarkable variation of the dynamic sea level (DSL) is o ...

Since ancient times, Chile's wildfires have shaped the country's landscape, but today, as in many other parts of the world, the fire regime – pattern, frequency and intensity – has grown at an alarming rate. In 2014, >8000 fires were responsible for burning c. 130,000ha, making it the worst year in Chile's recent history ...

Existing quantifications of the Shared Socioeconomic Pathways (SSP) used for climate impact assessment do not account for subnational population dynamics such as coastward-migration that can be critical for coastal impact assessment. This paper extends the SSPs by developing spatial projections of global coastal population distribution for the five basic SSPs. Based on a series of coastal migratio ...

Thanks to early topographic surveys in Switzerland, accurate maps are available, which enable us to trace glacier changes back in time. The earliest map for all of Switzerland that is usable for a detailed analysis is the Dufour map from around 1850 with subsequent topographic maps on a ~20year interval. D ...

Abstract:
... In the area south-east of Mount Kenya, four previously unrecorded peralkaline rhyolitic (pantelleritic) ash flow tuffs have been located. These predominantly greyish welded and non-welded tuffs form up to 12m thick units, which are sometimes characterized by a basal vitrophyre. The four flow units yielded ⁴⁰Ar/³⁹Ar ages ranging from 6.36 to 8.13Ma, indicating a period of ~1.8Ma of pantelleritic vo ...

Here we present the first low-temperature thermochronology data from eastern Marie Byrd Land, an area that stretches ~1000km along the rift system, in order to shed light on its development. Furthermore, we petrographical ...
