Socio-spatial inequalities in tobacco retail availability and smoking in megacities of China: a case study of Shanghai
(The University of Edinburgh, 2023-03-09)BACKGROUND: China is the world’s biggest manufacturer and consumer of tobacco products. In 2019, the smoking prevalence was 26.6%, with a large gender disparity (50.5% of men and 2.1% of women). Over 1 million deaths and ... -
Controls on sediment flux in active mountain ranges
(The University of Edinburgh, 2023-02-13)The shape of landforms at the Earth's surface is determined by a balance between processes creating topography and relief (tectonic uplift) and processes removing relief (denudation by rivers or glaciers, earthquakes, ... -
Simulating the impact of wind and radiation on snow dynamics across linear disturbances in boreal forests
(The University of Edinburgh, 2023-02-03)Boreal forests are Earth‘s second largest forest biome, covering an area of 12.0–14.7 million km2. Winters are typically long, cold and dry, creating ideal conditions for sustaining snowpacks throughout this period. The ... -
Nutrient cycling in the Arctic and Subarctic oceans: a stable isotope study
(The University of Edinburgh, 2023-02-02)Anthropogenic global warming is actively changing nutrient supply and the food web of the Arctic Ocean and the subpolar regions. This study uses the stable isotopes of dissolved silicon and nitrate, two vital nutrients ... -
Large-scale perspective on the meteorological modulation of air quality over China in winter
(The University of Edinburgh, 2023-01-25)Rapid economic and industrial growth in China has led to serious air pollution with high concentrations of suspended fine particulate matter (PM2.5), in particular during winter. On a regional scale, meteorological ... -
Examining ground-based in situ monitoring capability to improve understanding of the atmospheric methane budget
(The University of Edinburgh, 2023-01-23)Methane (CH₄) is the second most abundant anthropogenic greenhouse gas. Amount fractions have been rising in recent years, but we still do not have a complete understanding of the driving forces behind these changes. It ... -
Woody plant diversity in tropical savannas of Africa and Australia
(The University of Edinburgh, 2023-01-13)Tropical savannas are a dominant biome on Earth characterised by co-dominance of woody plants (trees and shrubs) and grasses that is fundamental to understanding of the global carbon cycle. Tropical savannas display a high ... -
Applications of unsupervised machine learning in climate research
(The University of Edinburgh, 2023-01-13)The use of machine learning in climate science is expanding rapidly after its success in other fields. The more powerful data driven models of machine learning show promise to give us more accurate predictions of and ... -
East Australian, Tasmantid and Lord Howe volcanoes: exploring the origins of three, contemporaneous, parallel chains of volcanism
(The University of Edinburgh, 2022-11-30)At greater than 3000 km long, and 500 km wide, the East Australian volcanic chain is one of the largest intraplate volcanic regions in the world and is represented by over 50 individual provinces, which erupted during ... -
Beetles and the development of Thorne Moors, SE Yorkshire, UK
(The University of Edinburgh, 2022-11-30)This project investigates the potential of terrestrial Coleoptera for monitoring and anticipating change in a modied raised mire ecosystem, so as to inform ongoing ecological restoration and to aid conservation management ... -
Reconstructing the late-Quaternary glacial history of northeastern Patagonia (43°S, 71°W): new insights from geomorphology, geochronology and numerical glacier modelling
(The University of Edinburgh, 2022-11-29)Former investigations conducting geomorphological mapping of Patagonia, a region formerly covered by an extensive ice sheet, have revealed a uniquely rich record of Quaternary glacial sediment-landform assemblages. ... -
Using geophysical data to understand liquid water dynamics in seasonal snow
(The University of Edinburgh, 2022-11-24)Modelling and monitoring seasonal snow is critical for water resource management, flood forecasting and avalanche risk prediction. Snowmelt processes are of particular importance. The behaviour of liquid water in snow ... -
Potential of observables for global and regional atmospheric CH₄ budget estimation
(The University of Edinburgh, 2022-09-30)Methane (CH₄) is the second most important anthropogenic greenhouse gas (GHG) in terms of radiative forcing since 1750, and atmospheric mixing ratios are on the rise globally. However, our understanding of its fluxes is ... -
4D structure of biochar and its impact on soil water characteristics
(The University of Edinburgh, 2022-08-30)Intensification of agricultural practices is necessary to support a growing global population. Water movement and storage in soils are very crucial for successful intensification of agriculture. They are important for ... -
Improving inversions of regional outer core surface flow models through the application of spherical slepian function
(The University of Edinburgh, 2022-07-29)There are multiple applications of the Earth's magnetic field to industry and science (for example navigation and satellite operations) so it is critical to understand how the magnetic field is generated and to accurately ... -
Interactions between ice shelves and phytoplankton blooms in the Amundsen Sea, and their relevance to the Southern Ocean
(The University of Edinburgh, 2022-07-29)The coastal Southern Ocean is both highly sensitive to climate change and disproportionately important as a regulator of global carbon and nutrient fluxes. In particular, the polynyas which occur at many locations along ... -
High-pressure study of the system Fe-Fe3S and its implications for sulphur in Earth’s core
(The University of Edinburgh, 2022-06-30)The composition of the Earth’s core is unknown, beyond being composed of mostly iron and nickel. Seismological observations revealed that the core is less dense than Fe by 7% in the outer core and 4% in the inner core. ... -
On primaries-only travel times construction using Marchenko redatuming
(The University of Edinburgh, 2022-06-30)Extraction of primaries-only reflection data from full surface reflection data by a combina- tion of Marchenko redatuming and convolutional interferometry, incorporates artefacts, and noise following the constructed ... -
Hydrogen storage in depleted gas fields: capacity and performance
(The University of Edinburgh, 2022-06-29)The Paris Agreement to limit anthropogenic warming to 1.5 °C above pre-industrial levels requires rapid reduction of greenhouse gas emissions. The UK has a large natural gas demand which varies massively across the ... -
Model selection in earthquake recurrence relationships: b-value bias in tectonic, volcanic and induced seismological settings
(The University of Edinburgh, 2022-06-28)The Gutenberg-Richter (GR) law logF = a − bm expresses the relationship between the magnitude of earthquakes (m) and their frequency of occurrence (F) via two constants a and b, which describe the seismicity rate and the ...
