Summary: Petrological, geochemical, and biostratigraphical investigations were conducted on samples from Jordan to understand the factors influencing phosphorite deposition. Marker species indicate the Campanian and Eocene periods. The presence of certain ecological marker species suggests the occurrence of cold periods. The composition and variations in isotope ratios indicate different periods of deep water circulation, submarine weathering, and continental weathering.

Summary: The study integrated molecular geochemistry, inorganic and isotopic studies to recognize the geochemical characteristics of sediments from the Aptian to Campanian periods in the Western offshore to Central Orange Basin. The results showed that the sediments were predominantly influenced by marine sources, with some samples being thermally mature enough to produce petroleum. Geochemical analysis also indicated a continental rift of passive margin settings, revealing the breakup of Gondwana and the opening of the Atlantic Ocean Margin.

Summary: This study examines the Upper Triassic Chinle Formation in Petrified Forest National Park, Arizona, using data from the Colorado Plateau Coring Project. The research suggests a possible correlation between the Manicouagan impact event and the Adamanian-Revueltian biotic turnover event, but establishing a causal relationship between the two remains challenging. Additionally, the study finds that the climate became drier, which may have contributed to the biotic turnover event.

Summary: The history of the nitrogen cycle on Earth is closely linked to the redox evolution of the surface environment. Interpretation of nitrogen isotopic analyses in past environments requires linking with redox-sensitive proxies. Combining N isotope and redox analyses is essential to interpret biologic isotopic signals during times of dynamic redox in the ocean-atmosphere system.

Summary: This study provides detailed geochemical research on the Longwangmiao Formation in the central Sichuan Basin of South China, revealing the paleoenvironmental changes and the origin of carbon isotope excursion events during this period. The results indicate that continental weathering is climatically controlled and was influenced by local karst formation and regional regressions during transgressions. The study also highlights the warm and humid paleoenvironment during the early Toyonian, gradually transitioning to colder and drier conditions in the middle Toyonian.

Summary: Through the chronology study of lacustrine deposits of the Upper Dingqing Formation in the Lunpola Basin, Central Tibet, it has been determined that the geological period is middle Miocene (15-12 Ma). Stable isotope and palynological records indicate a climatic transition around 13.8 Ma, characterized by cooler and drier climate. New palynological elevation reconstructions suggest a maximum paleo-elevation of 3100-3600 m (average 3350 m) for the Lunpola Basin, consistent with floating-leaf plants data. This study provides new insights into paleoenvironmental reconstructions and paleo-elevation estimates of the Lunpola Basin, Central Tibet.

Summary: The study compared oxygen isotope profiles from two marine bivalve mollusk species living in the same region, finding that they may record different aspects of environmental conditions. However, the findings suggest that the fossil record could provide more detailed archives of past environmental conditions than previously thought. Future studies should focus on high-resolution, short-duration calibrations to further understand environmental variations.

Summary: Several types of laboratory experiments were conducted to evaluate isotope fractionation caused by phase transfer process for a selection of common environmental contaminants. Carbon and hydrogen isotope fractionation caused by vaporization of non-aqueous phase liquid (NAPL), volatilization from water, and dissolution into an organic solvent (TGDE) were investigated. The results showed significant isotope fractionation during NAPL vaporization and volatilization from water, while no significant fractionation was observed during the air-TGDE partitioning process, except for certain compounds.

Summary: Stable isotope analysis is an important technique in food web ecology, but its effectiveness can be unclear in complex systems. The use of heavy isotope tracers has been suggested as a way to enhance the utility of stable isotope analysis, but this study found that labeling could potentially affect isotopic fractionation and bias conclusions. While the physiological and activity levels of organisms in autotrophy-based and detritus-based aquatic food webs were not significantly affected by labeling, the study supported the isotopic redundancy hypothesis, which suggests that metabolic processes can be altered by discrete quantum mechanical states.

Summary: The study of the coastal peatlands in the Vistula Lagoon provides valuable insights into the regional sea-level and storminess changes during the middle and late Holocene. The analysis of peat and gyttja revealed the sea-level rise from 20 to 8 meters below present sea level between 9000 and 7000 years ago at an average rate of 6 mm/year. The rate of sea-level rise decreased to 2.75 mm/year between 7000 and 5000 years ago, with the sea-level being 2.5 meters lower than present around 5000 years ago. In the last 5000 years, the sea-level has risen at a rate of 0.5 mm/year to its current position. The study also identified ten periods of increased sea-level rise and storminess between 7000 and 1500 years ago, which were mainly associated with cold periods or transitions and linked to variations in regional solar irradiation.

Summary: Understanding the diet of whale sharks is crucial for conservation strategies, and this study suggests that parasitic copepods can be used as a proxy to infer the short-term foraging habitats and trophic positions of whale shark hosts. The study found a strong correlation between the nitrogen isotope compositions of the parasites and whale shark hosts, indicating consistent trophic positions over time. However, the carbon isotope compositions showed a weak correlation, suggesting differences in physiology and lifecycle between the copepod parasite and the host.

Summary: Fertilizers are beneficial for agriculture but can lead to water pollution. This study in Ghana's Densu River Basin used hydrochemical and multi-isotope data to identify nitrate pollution sources and processes. The findings showed that nitrification was the main process upstream, while mixing of sources and denitrification dominated downstream. The study also revealed that N fertilizers and soil N were the main nitrate sources upstream, while manure/sewage became dominant downstream reflecting different land use. Soil erosion and runoff were found to contribute to nitrate pollution as much as N fertilizers, and manure/sewage impacted groundwater. Multi-isotope analysis provided additional insights not possible with traditional methods.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
