Summary: The study identified distinct phylogenetic branches in Yersinia pestis strains isolated in the Northern Caspian and Northern Aral Sea regions, with the early 2.MED4 branch preceding the later 2.MED1 branch. The 2.MED1 branch emerged as the etiological agent of plague outbreaks in the early 20th century and spread to the Caspian Sea region, Caucasus, and Central Asia in the later part of the 20th century.

Summary: This study examines the seasonal variation of aeolian dust sources in the northeast Arabian Sea through the analysis of wet deposit particulate samples. The mineralogical composition and isotopic signatures reveal that the Arabian Peninsula and Northeast Africa are the dominant dust sources during the monsoon period, while the Thar desert and Southwest Asia become more prominent at the end of the monsoon.

Summary: Sampling surveys conducted in the Alvarado Lagoon and Puerto Cortes Bay in Honduras showed that both environments were highly eutrophic and served as important sources of nutrients and particulate matter to the coastal zone. Despite some improvement in offshore water quality, concentrations of chlorophyll and nutrients remained higher than those typically found in non-polluted coral reefs in the Caribbean region. Therefore, in situ monitoring and assessment of these aspects are crucial for evaluating the ecological functioning and threats to the Mesoamerican Barrier Reef System (MBRS) and implementing appropriate management policies.

Summary: Mercury (Hg) enters the Arctic region through the atmosphere due to its high migration capacity, and is absorbed by sea bottom sediments. The Chukchi Sea's sedimentation is influenced by highly productive Pacific waters from the Bering Strait and a terrigenous component from the Siberian Coastal Current. The Hg concentrations in the study area ranged from 12 to 39 μg/kg in bottom sediments, with a background concentration of 29 μg/kg determined through sediment dating. The fine sediment fractions had a Hg concentration of 82 μg/kg, while the sandy fractions (> 63 μm) ranged from 8 to 12 μg/kg. In recent decades, Hg accumulation in bottom sediments has been controlled by the biogenic component, and the Hg in the studied sediments exists in sulfide form.

Summary: The study investigated the geomorphological evolution of the Qilihai lagoon system, showing that construction projects increased net deposition and tidal asymmetry affected bed thickness changes. However, bed erosion or deposition is also influenced by external sediment supply and river discharge.

Summary: A single plate boundary fault system in the western Mediterranean, which represents an underappreciated seismic and tsunami hazard, has been identified. The current diffuse-strain model of plate collision in the region is untested due to most deformation occurring underwater. By analyzing active offshore fault systems, the slip of the fault system and its hazard level have been estimated.

Summary: The Sea of Japan is a unique marginal sea in the western North Pacific characterized by four shallow straits. Terrigenous sediments in the western JS are mainly derived from northern China and coastal areas in the Far East, with an increase in sea ice coverage during the Last Glacial Maximum contributing to the accumulation of terrigenous debris. Changes in atmospheric circulation and sea level during the last deglaciation and early Holocene significantly affected the input of terrigenous debris, while the opening of the Tatar Strait after 8 ka led to the development of the Liman Cold Current, transporting large quantities of volcanic materials to the study area.

Summary: The DEWEX project aims to better understand the impact of deep convection in the north-western Mediterranean on the general circulation and biogeochemical cycles of the Mediterranean Sea, by developing a coupled physical and biogeochemical model and estimating processes such as oxygen cycling, budgeting, and air-sea exchanges. The study reveals a seasonal pattern in the uptake of atmospheric oxygen in the deep-convection area, with oxygen injected at the sea surface primarily transported through deep convection and gradually exported to the south and west of the western basin.

Summary: Cation exchange capacity (CEC) plays a key role in soil studies. Predicting CEC using artificial intelligence models with readily available soil properties is an effective solution. This study used physical and chemical properties of the soil as input data for the AI models and compared the efficiency of different models. The coupled models (ANFIS-DE and ANFIS-PSO) showed higher efficiency compared to the ordinary ANFIS model.

Summary: This research investigates the formation of coastal cliffs along the western coast of the Dead Sea. The study identifies the impact of seasonal lake level changes and winter storms on cliff formation. The findings suggest that the decline in lake level during summer months and the erosion caused by winter storms contribute to the creation of the staircase morphology. The research highlights the importance of understanding the controlling processes and environmental conditions for managing coastal erosion.

Summary: This study estimates the baseline of heavy metal pollution in sediments of Limoncocha lagoon and applies single and integrated pollution indices to assess contamination levels and ecological risks. Nickel, zinc, and copper are identified as priority pollutants with a moderate pollution level and medium-low risk level.

Summary: The study found that the QAA a443 and GSM-A a443 algorithms provide the most accurate representation of in-situ CDOM conditions, with geographic variables showing no significant impact on algorithm accuracy. Satellite observations of CDOM in the Pacific Arctic region should be used cautiously for representing in-situ conditions.

Summary: The study of climate change during the mid-to-late Holocene transition based on fossil corals in the South China Sea revealed a rapid cooling and wetting event around 3500-3800 years BP, possibly related to changes in the Asian summer monsoon and North Atlantic climate, and could have contributed to the fall of the Xia Dynasty.

Summary: The study found that the content of PAHs in sealed soils and asphalt concrete is significantly higher than that in unsealed urban soils and background soils, with low molecular weight PAHs being more prevalent in sealed soils. The enhanced accumulation of PAHs in sealed soils may be attributed to the conservation of PAHs by soil organic matter under anaerobic conditions.

Summary: This study obtained the first dataset on the solubilities and partitioning of metals and metalloids during spring rains in Moscow. It found that there was a 20%-50% increase in solubility in acid rains compared to non-acid rains for certain metals. Anthropogenic sources contributed significantly to the concentration of soluble MMs, while crustal materials were the important contributors for the insoluble MM.

Summary: This study is the first to determine the levels of BaP pollution in different land use zones and roads in three cities in Crimea. The results show that the levels of BaP in soils and road dust are significantly higher than the background level, especially in PM10 particles. This indicates a serious pollution situation in these three cities.

Summary: This study investigates the combined effect of PTEs and PAHs pollution on macrophyte plants and their bioindication status in small rivers. The research reveals the impact of pollution on the accumulation and morphological changes of Phragmites australis, as well as the structural alterations in its cells. The findings demonstrate that the nature and extent of these alterations can serve as bioindicators for assessing soil phytotoxicity caused by PTE and PAHs accumulation.

Summary: The floodplains and seacoasts of southern Russia have undergone urbanization, developed agriculture, and rapid industrial development. Anthropogenic activities have led to long-term pollution in the environment, posing threats to ecosystems and public health. This study aimed to assess the risks posed by potentially toxic elements (PTEs) and polycyclic aromatic hydrocarbons (PAHs) in the topsoil. The results showed that PAHs pose a greater potential ecological risk, while PTEs have a higher risk of negative impacts on human health. Comprehensive risk assessments should consider the combined influence of different components.
