title: BSTS and GWLR Modelling Impacts of COVID-19 Lockdowns on theSpatio-temporal Patterns of London Crimes Datasets

description: Given the paramount impacts of COVID-19 on people’s lives in the capital of the UK, London, it was foreseeable that the city’s crime patterns would have undergone significant transformations, especially during lockdown periods. This study aims to testify the crime patterns’ changes in London, using data from March 2020 to March 2021 to explore the driving forces for such changes, and hence propose data-driven insights for policy makers and practitioners on London’s crime deduction and prevention potentiality in post-pandemic era. (1) Upon exploratory data analyses on the overall crime change patterns, an innovative BSTS model has been proposed by integrating restriction-level time series into the Bayesian structural time series (BSTS) model. This novel method allows the research to evaluate the varied effects of London’s three lockdown periods on local crimes among the regions of London. (2) Based on the predictive results from the BSTS modelling, three regression models were deployed to identify the driving forces for respective types of crime experiencing significant increases during lockdown periods. (3) The findings solidified research hypotheses on the distinct factors influencing London’s specific types of crime by period and by region. In light of the received evidence, insights on a modified policing allocation model and supporting the unemployed group was proposed in the aim of effectively mitigating the surges of crimes in London.

title: The Role of Photochemistry in Driving the Composition of Dissolved Organic Matter Found in Glacier Environments

description: Dissolved organic matter (DOM) in glacier environments is aliphatic-rich, yet studies have proposed DOM originates from allochthonous, aromatic and often aged material. Allochthonous organic matter (OM) is exposed to ultraviolet radiation both in atmospheric transport and post-deposition on the glacier surface. Thus, we evaluate photochemistry as a mechanism to account for the compositional disconnect between allochthonous OM sources and glacier DOM composition. Six solid endmember OM sources were leached in ultrapure water and photo-irradiated for 28-days in a solar simulator, until &gt; 90 % of initial chromophoric DOM was removed. Ultrahigh-resolution mass spectrometry was used to compare the molecular composition of leachates pre- and post-irradiation to DOM sampled from supraglacial and bulk runoff from the Greenland Ice Sheet and Juneau Icefield, respectively. Photo-irradiation drove molecular level convergence between the initially aromatic-rich leachates and aromatic-poor glacial samples, selectively removing aromatic compounds (-80 ± 19 %) and producing aliphatics (+75 ± 35 % relative abundance). The molecular level composition of glacial DOM was statistically indistinguishable to post-irradiation leachates. Furthermore, Bray-Curtis analysis showed substantial similarity in the molecular formulae present between glacier samples and post-irradiation leachates. Post-irradiation leachates contained 84 ± 7.4 % of the molecular formulae, including 72 ± 17 % of the aliphatic formulae, detected in glacier samples. Therefore, photodegradation provides a mechanistic pathway which may account for the disconnect between proposed aromatic, aged sources of OM and the aliphatic-rich fingerprint of glacial DOM. More work is required to quantify rates and magnitudes of photodegradation possible in transit to and on glacier surfaces. Nonetheless, given the high ultraviolet conditions of both these environments, photochemical alteration of DOM is likely significant. Thus, photochemical transformation of allochthonous OM may mediate the composition of DOM found in glacier environments and thus this mechanism should be considered when assessing the DOM chemistry therein.

title: Soil gas analysis, western Pyrenees

description: Native hydrogen (H2) may represent a new carbon free energy resource, but to date there is no specific exploration guide to target H2-fertile geological settings. Here, we present the first soil gas survey specifically designed to explore H2 migration in a region where no surface seepage has been documented so far. We choose the Pyrenean orogenic belt and its northern foreland basin (Aquitaine, France) as a playground to test our strategy. The presence of a mantle body at shallow depth (&lt;10 km) under the Mauléon Basin connected to the surface by major faults is considered as a preliminary pathfinder for H2 generation and drainage. On this basis, more than 1,100 in situ soil gas analysis (H2, CO, CO2, CH4, H2S, and 222Rn) were performed at ~1 m depth at the regional scale along a 10 × 10 km grid spanning over 7,500 km2 25 . The analysis campaign reveals several hot spots to the north of the Mauléon Basin where H2, CO2 and 222Rn concentrations exceed 1000 ppmv, 10 vol% and 50 kBq m-3 , respectively. Most of these hot spots are located along the North Pyrenean Frontal Thrust and other related faults rooted in the mantle body. These results, together with evidence of fluid migration at depth, suggest that H2 may be sourced from mantle rocks serpentinization and carried to the surface along major thrusting faults. Hydrogen traps remain unidentified up to now but the presence of salt-related structures (diapirs) near these hot spots could play this role.
