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 ... -
Sequential biochar systems: synergies in carbon recycling
(The University of Edinburgh, 2022-06-23)Carbon dioxide removal technologies present an opportunity to alleviate some of the worst consequences of climate change by actively removing CO2 from the atmosphere while the decarbonization of our economies progresses. ... -
Vanadium biogeochemical cycling in a lake (Kinghorn Loch, U.K.) following historical red mud pollution
(The University of Edinburgh, 2022-06-20)V is a potentially toxic metal that is gaining new interest in terms of its behaviour within environmental systems. Environmental concentrations of V are likely to increase as the consequence of the increasing production ... -
Design and development of a compact Earth observation instrument for high resolution monitoring of atmospheric methane
(The University of Edinburgh, 2022-06-15)Methane is a potent greenhouse gas, with recent growth in atmospheric concentration potentially linked to human-driven emissions. Reducing these anthropogenic emissions is an effective and rapid mitigation strategy for ... -
Exploring the biophysical and socio-economic barriers to carbon sequestration in viticultural soils
(The University of Edinburgh, 2022-06-15)To avoid catastrophic changes in the climate system by the end of the 21st century, the world must pursue drastic climate change mitigation strategies. All scenarios for containing the increase in global surface temperatures ... -
Satellite and UAV remote sensing of debris-covered glaciers
(The University of Edinburgh, 2022-06-13)Mountain glaciers play a crucial role in the global provision of water resources. The majority of these glaciers are retreating rapidly in response to anthropogenic climate change, posing serious risks to downstream ... -
Macroecological patterns of vegetation change across a warming tundra biome
(The University of Edinburgh, 2022-06-10)The climate is changing across the globe at unprecedented magnitudes, and temperatures in the Arctic are increasing at three times the rate of the global average. Climate change impacts are being felt across the tundra ... -
Water and carbon in the early solar system
(The University of Edinburgh, 2022-06-10)Hydrogen (H) is the most abundant element in the universe. The original budget and speciation of major volatiles, such as hydrogen and carbon ( C), in the silicate material and atmospheres of rocky bodies in our Solar ... -
Constraints on tree growth, impacts of tropical cyclones and outcomes of community management in the Miombo woodlands
(The University of Edinburgh, 2022-06-08)The Miombo woodlands of southern Africa are a globally significant store of carbon (C) and biodiversity. They also provide services for more than 150M people across several of the world’s most economically impoverished ... -
Causes of regional climate variability over the last millennium
(The University of Edinburgh, 2022-06-08)During the last millennium, natural variations of regional to large-scale temperature were driven by varying orbital, volcanic and solar forcing. Reconstructions of surface temperature derived from natural proxy archives ... -
Spatial and temporal variations in thesediment fluxes and metal contaminationin nickel mining-impacted catchments
(The University of Edinburgh, 2022-06-07)Understanding of the entire sediment routing system and the links between sources and storage at the catchment scale remains limited in nickel mining-affected regions. This research aims to address the knowledge gap by ... -
Modelling actual and potential natural vegetation types: an approach to support the ecological restoration and conservation programmes in Jordan
(The University of Edinburgh, 2022-06-07)Lying at the junction of Africa, Asia, and the Mediterranean, Jordan is home to a range of diverse and unique vegetation. The country also boasts some of the oldest anthropogenic landscapes in the world due to its ... -
Investigating tropospheric and surface ozone sensitivity from present day to future
(The University of Edinburgh, 2022-06-07)Tropospheric ozone (O3) is an important reactive gas in the atmosphere influencing human health, ecosystems and climate. Since the mid-20th century, scientists started to explore the mechanism of tropospheric O3 ... -
Major evolutionary transition: sensory adaptations of Mesozoic thalattosuchians and their extant crocodylian relatives
(The University of Edinburgh, 2022-05-04)A prime example of a group that underwent a major evolutionary transition are thalattosuchian crocodylomorphs, extinct relatives of modern crocodiles. Known from the Early Jurassic to the Early Cretaceous (ca. 191–125 Ma), ... -
