Abstract. Extreme biomass burning (BB) events, such as those seen during the 2019–2020 Australian bushfire season, are becoming more frequent and intense with climate change. Ground-based observations of these events can provide useful information on the macro- and micro-physical properties of the plumes, but these observations are sparse, especially in regions which are at risk of intense bushfire events. Satellite observations of extreme BB events provide a unique perspective, with the newest generation of geostationary imagers, such as the Advanced Himawari Imager (AHI), observing entire continents at moderate spatial and high temporal resolution. However, current passive satellite retrieval methods struggle to capture the high values of aerosol optical thickness (AOT) seen during these BB events. Accurate retrievals are necessary for global and regional studies of shortwave radiation, air quality modelling and numerical weather prediction. To address these issues, the Optimal Retrieval of Aerosol and Cloud (ORAC) algorithm has used AHI data to measure extreme BB plumes from the 2019–2020 Australian bushfire season. The sensitivity of the retrieval to the assumed optical properties of BB plumes is explored by comparing retrieved AOT with AErosol RObotic NETwork (AERONET) level-1.5 data over the AERONET site at Tumbarumba, New South Wales, between 1 December 2019 at 00:00 UTC and 3 January 2020 at 00:00 UTC. The study shows that for AOT values > 2, the sensitivity to the assumed optical properties is substantial. The ORAC retrievals and AERONET data are compared against the Japan Aerospace Exploration Agency (JAXA) Aerosol Retrieval Product (ARP), Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue over land, MODIS MAIAC, Sentinel-3 SYN and VIIRS Deep Blue products. The comparison shows the ORAC retrieval significantly improves coverage of optically thick plumes relative to the JAXA ARP, with approximately twice as many pixels retrieved and peak retrieved AOT values 1.4 times higher than the JAXA ARP. The ORAC retrievals have accuracy scores of 0.742–0.744 compared to the values of 0.718–0.833 for the polar-orbiting satellite products, despite successfully retrieving approximately 28 times as many pixels over the study period as the most successful polar-orbiting satellite product. The AHI and MODIS satellite products are compared for three case studies covering a range of BB plumes over Australia. The results show good agreement between all products for plumes with AOT values ≤ 2. For extreme BB plumes, the ORAC retrieval finds values of AOT > 15, significantly higher than those seen in events classified as extreme by previous studies, although with high uncertainty. A combination of hard limits in the retrieval algorithms and misclassification of BB plumes as cloud prevents the JAXA and MODIS products from returning AOT values significantly greater than 5.
Plant functional traits modulate the effects of soil acidification on above- and belowground biomass

Abstract. Atmospheric sulfur (S) deposition has been increasingly recognized as a major driver of soil acidification. However, little is known about how soil acidification influences above- and belowground biomass by altering leaf and root traits. We conducted a 3-year S-addition experiment to simulate soil acidification in a meadow. Grass (Leymus chinensis (Trin.) Tzvelev) and sedge (Carex duriuscula C.A.Mey) species were chosen to evaluate the linkage between plant traits and biomass. Sulfur addition led to soil acidification and nutrient imbalances. Soil acidification decreased specific leaf area (SLA) but increased leaf dry-matter content (LDMC) in L. chinensis, showing a conservative strategy and thus suppressing aboveground instead of belowground biomass. However, in C. duriuscula, soil acidification increased plant height and root nutrients (N, P, S, and Mn), favoring competition for natural resources through enhanced above- and belowground biomass, i.e., adoption of an acquisitive strategy. Increased soil acidity resulted in an overall reduction in aboveground community biomass by 3 %–33 %, but it led to an increase in community root biomass by 11 %–22 % due to upregulation as a result of higher soil nutrient availability. Our results demonstrate that both above- and belowground plant biomass is affected by S-induced acidification. Understanding the linkage between plant biomass and functional traits contributes to a better understanding of plant–soil feedback in grassland ecosystems.
The Role of Economic Geologists in Water Management Related to Mining

Editor’s note: The aim of the Geology and Mining series is to introduce early career professionals and students to various aspects of mineral exploration, development, and mining in order to share the experiences and insight of each author on the myriad of topics involved with the mineral industry and the ways in which geoscientists contribute to each.

Abstract
Water has always been an important issue for mineral exploration and mining companies. In recent years, water-related issues have increasingly placed a constraint on the development of new projects, while mine closure issues have created billion-dollar legacies for governments. Water access and management creates not only project risks but also opportunities. There are opportunities for geoscientists to help mitigate water-related issues early in a development, particularly for the economic geologists who play a crucial role in gathering data and geologic understanding during the early mine life cycle. Geologists can contribute to the understanding of baseline water systems and help to mitigate the potential effects that mining may pose for local ecosystems and to the communities that depend on them.
Drivers of Global Mineral Demand: 1900–2050

Abstract
The global demand for minerals has long been known to be characterized by periods of high demand followed by periods of low demand. These are often referred to as cycles. There are cycles of short (multiyear) duration and cycles of long (multidecade) duration. This paper seeks to explain the driving forces behind the long-duration cycles. There have been five such cycles since 1900. Four of them were in the 20th century, and the fifth was the China mining boom, which lasted from about 2000 to 2015. I interpret the main driver of these cycles to be the pace of urban, or suburban, construction. When this is proceeding at a rapid pace, global mineral demand is high. When construction activity slows, mineral demand slows with it.
In the 20th century it was the nations of Europe, North America, and, later in the century, the Soviet Union and Japan that were home to most of the world’s construction activity. Their economic fortunes drove the century’s four long-duration cycles. The century began with a 30-year period of high demand driven by the transformation of these economies from predominantly agriculture based to predominantly urban industrial. It ended with a nearly 30-year period of low demand as these same economies, having already urbanized, moved into being predominantly service-based economies, which have a lower per capita mineral demand. At the beginning of the 21st century, China took the lead with its remarkable transformation from an economy that was farm based to one that was urban industrial, which drove global mineral demand to a high level.
I argue that the world is now heading into a 30-year period of low urban construction-driven demand as China turns away from reform, India discovers that its economic success is built on weak foundations, and the “advanced countries” continue with their metals-lite transformation toward ever more sophisticated service activities. However, urban construction may be about to be displaced as the principal driver of global mineral demand. This new driver is the restructuring of global energy systems, or, to be more specific, the shift from hydrocarbon-based energy to solar and wind-based energy. Producing energy from solar and wind is far more materials-intensive than from hydrocarbons. Will this shift propel global mineral demand back to high?
Another Look at Marine Minerals

Abstract
Deep-sea mining is taking another step closer to reality. Early leases for exploration in the central Pacific manganese nodule fields and elsewhere in the oceans are coming to an end, and contractors are faced with a choice—extend the licenses to continue exploration or apply to mine the deposits they have found. The first 15-year licenses were originally signed into effect by the International Seabed Authority (ISA) in 2001 and began to expire in 2016. With no operations in a position to commence mining and, more importantly, no regulations in place to allow it, most exploration licenses were simply renewed. Eight of the original licenses were extended for five more years, some twice, and new licenses have been granted. Today, there are 31 contracts for exploration: 19 for manganese nodules, 7 for sea-floor massive sulfides, and 5 for Co-rich crusts. The first contract for massive sulfide exploration expires in 2026; the first for Co-rich crusts expires in 2029. Meanwhile, there is strong interest from a number of countries in the mineral resource potential of their exclusive economic zones (EEZs), particularly Japan and Norway. Against this backdrop of rapidly shifting exploration activity, it may be time to take another look at marine minerals as a resource for the future. In a report entitled “The Future of the Ocean Economy by 2030,” the Organization for Economic Cooperation and Development (OECD) asked, “What new developments could result in a complete revision of offshore mineral potential?” For most parts of the oceans, the answer to this question is plagued by inadequate mapping and a lack of geologic knowledge as a basis for assessing the resources. However, new approaches to exploration are emerging, and recent discoveries, such as on the continental shelf and beneath the cover of sediment, are changing our view of the resource potential.

Objectives: The study aimed to determine the temporomandibular joint (TMJ) findings, to investigate the prevalence contribution of this sequence on cases in which cranial magnetic resonance examination was performed and three-dimensional (3D) T2-SPACE (T2-weighted sampling perfection with application-optimized contrasts using different flip-angle evolutions) sequence was used by retrospectively scanning the magnetic resonance imaging (MRI) archive of our hospital, and to reveal the advantages of the 3D-T2 SPACE sequence in patients with TMJ disorders.
Patients and methods: The cross-sectional retrospective study was conducted with 499 patients (289 females, 210 males; mean age: 50.1±17.7 years; range, 8 to 92 years) who underwent brain MRI and had 3D-T2 SPACE between March 1, 2021 and March 1, 2022. Two radiologists analyzed the TMJs of the subjects included in the study in 3D-T2 SPACE sequences.
Results: At least one incidental finding was detected in the TMJ in 37.1% (n=185) of the patients included in our study. In our study, the most common (13.6%) MRI findings were osteoarthritic changes and synovial cysts. Joint effusion (13.2%) and disc displacement (9%) were less frequent. When the relationship between the age of the patients and the presence of incidental findings, degeneration, effusion, disc displacement, and cyst was examined, the age of the patients with incidental findings (p=0.001) and osteoarthritic changes (p<0.001) was statistically significantly higher.
Conclusion: Incidental findings, particularly osteoarthritic changes and synovial cysts, can be seen quite commonly in the TMJ in brain MRI using 3D T2-SPACE sequences in the general population. The 3D T2-SPACE sequence provides valuable information in the recognition of TMJ disorders.

Published: May 2024

Objectives: This study aimed to compare the effects of trigger point injections and stretching exercises in patients with noncardiac chest pain (NCCP) associated with myofascial pain syndrome.
Patients and methods: This prospective randomized controlled trial included 50 patients with noncardiac chest pain and trigger points in the pectoralis muscles between October 2019 and June 2020. The patients were randomly assigned to receive trigger point injections into the pectoralis muscles and exercise (n=25; 15 males, 10 females; mean age: 42.8±9.2 years; range, 25 to 57 years) or only perform exercise (n=25; 11 males, 14 females; mean age: 41.8±11.2 years; range, 18 to 60 years). The primary outcome was pain intensity at the first month and three months after the first treatment session, measured using the Visual Analog Scale from 0 to 100. The secondary outcome was the Nottingham Health Profile score.
Results: Treatment with stretching exercises and trigger point injection resulted in significant pain reduction compared to stretching exercises alone, and the reduction was persistent at the three-month follow-up (p<0.001). A between-group comparison showed no significant difference in the Nottingham Health Profile (p=0.522). Complications related to the procedure or severe adverse events attributable to treatment were not reported.
Conclusion: Trigger point injection combined with stretching exercises is an efficient treatment for noncardiac chest pain related to myofascial pain syndrome compared to exercise treatment alone.
