Citizen science illuminates the nature of city lights Open
The image of Earth at night from space, with its constellations of cities, has become iconic. However, our understanding of the source and scale of artificial light emissions is still in the dark, hampering urban environmental protection e…

Drivers of fluvial terrace formation and quantifying their impacts – Application to the Río Santa Cruz in Southern Patagonia Open
The Rio Santa Cruz in Southern Patagonia preserves a spectacular set of fluvial terraces along its approximately 200-km length across the Patagonian Steppe landscape, stretching from the proglacial Lago Argentino to the Atlantic Ocean. Exp…

Linking Glacial Exhumation and Fluvial Incision During the Mid-Pleistocene Transition, Southern Patagonia, Argentina Open
The Mid-Pleistocene Transition (MPT; ~1.2–0.9 Ma) marked a shift in global climate cycles, amplifying glacial-interglacial oscillations and lengthening their periodicity. In the Patagonian Andes, intensified erosion due to late-Mioce…

What’s in a Watt? Interpreting nightlights satellite data via citizen science observations Open
The image of Earth at Night from space has become iconic, but we are still in the dark when it comes to the question of to what extent different light source types contribute to city light emissions. Our team of citizen scientists used the…

Quantifying cut-and-fill terrace cycles since the Middle Pleistocene in the Patagonian Steppe, Argentina Open
The rapid response of Patagonian topography to ice-mass changes, facilitated by the presence of a slab-window, offers an ideal setting for investigating the interplay between surface processes, climate dynamics, and solid Earth rheology. T…

In-situ Weathering of Alluvial Sediments in the Southern Central Andes Recorded by Ground- and Space-Based Hyperspectral Reflectance Open
Alluvial fans comprise abandoned sedimentary surfaces undergoing physical and chemical weathering. While weathering pathways and kinetics have been described over seconds to decades, few field-based studies have quantified these processes …

River long profile modelling since the Mid-Pleistocene for the Río Santa Cruz, Southern Patagonia. Open
Alluvial rivers connect sediment sources in mountain belts to depositional basins. They not only transport water and sediment, but also adjust to changing forcing conditions by aggrading or incising their beds, a process potentially record…

Nachtlichter App Open
The relationship between satellite based measurements of city radiance at night and the numbers and types of physical lights installed on the ground is not well understood. Here we present the “Nachtlichter app”, which was developed to ena…

Pleistocene Landscape Evolution in Southern Patagonia: A Record of Regional Incision from 10Be Dating of Fluvial Terraces Open
Glacial and fluvial landforms record the recent history of Earth’s surface, and hold information on the climatic or tectonic processes that shape the landscape. Southern Patagonia hosts uniquely well-preserved fluvial cut-and-fill te…

Direct measurement of the contribution of street lighting to satellite observations of nighttime light emissions from urban areas Open
Nighttime light emissions are increasing in most countries worldwide, but which types of lighting are responsible for the increase remains unknown. Also unknown is what fraction of outdoor light emissions and associated energy use are due …

Teachers’ Work Practices in Kazakhstan: Some Comparative Insights from TIMSS 2011 to Guide Curriculum Implementation Open
This paper2 looks at the different norms of practice between mathematics teachers in two countries, Kazakhstan and England. These differences pose challenges and opportunities for the implementationof a new secondary curriculum in Kazakhst…

Perseptions of employability, skills and individual aspiration in a diversifying economy Open
Employability is a relatively new concept. The notion that post school educational institutions should play some role in preparing young people for employment really only came into focus as participation increased and the curriculum offeri…
