Summary: This study quantifies the timing and magnitude of coastal marine degradation in East Asia during the transition from the Holocene to the proposed Anthropocene. It reveals significant biological and environmental changes in an anoxic coastal marine basin, Beppu Bay, Japan, and suggests that anthropogenic degradation occurred in the 1960s. The sediment records from Beppu Bay could provide valuable insights into the coastal Holocene-Anthropocene transition in East Asia.

Summary: Lakes are important for ecosystem services and biodiversity, but cultural eutrophication remains a major threat to their health. The lack of long-term monitoring records limits our ability to manage lake eutrophication. This study developed a bio-indicator approach using diatom communities to infer trophic levels in lakes, and the results were consistent with monitoring data and land-use histories. However, recent shifts in diatom communities were not captured by traditional trophic level indices, highlighting the importance of new approaches in preventing the decline of lake ecosystems worldwide.

Summary: The study aimed to determine spatiotemporal variations in chlorophyll-a (Chl-a) concentration using hydroclimatic and nutrient variables in tropical reservoirs in Brazil. A model for Chl-a prediction was proposed based on the product of nitrogen, phosphorus, volume, and precipitation. The results showed that nutrients had a better predictability for Chl-a than hydroclimatic variables. Chl-a blooms were more frequent in periods of high precipitation and low volume, and their response to the parameters varied.

Summary: This study applies remote sensing to monitor long-term chlorophyll-a (Chl-a) concentrations and the trophic state index (TSI) in Lake Burdur, Turkey. Surface reflectances from Landsat satellite images are analyzed to estimate a 38-year time series of Chl-a concentrations. The results show variations in Chl-a concentrations over time, with higher concentrations in 2010 and 2021 and lower concentrations between 1991 and 1993. The TSI values suggest Lake Burdur has been mostly hypertrophic throughout the study period.

Summary: In this study, the lead and mercury content of 133 historical books published between 1704 and 2018 in southwest England were determined. It was found that most books contained high concentrations of lead, especially those published between the 19th century and 1960. Mercury was also detected in some books published in the Victorian era. These historical books could contribute to indoor lead pollution and improve evaluations of historical indoor pollution.

Summary: Monitoring marine ecosystems requires observations of attributes at different scales which traditional methods struggle to provide. Proximal optical sensing methods bridge this observational gap by tracking changes non-invasively. Underwater hyperspectral imaging shows potential for monitoring pigmentation and identifying minerals at small spatial scales.

Summary: Sediments from Lake Lubi'nskie in western Poland were analyzed to investigate the effects of environmental changes on the lake's limnology over the past 3,000 years. By studying varve microfacies, geochemical, pollen, and diatom data, as well as using an age-depth model based on varve counting and radiometric measurements, major phases of landscape and lake ecosystem transformations were identified. The study suggests that human activities in the catchment area, such as agriculture and deforestation, have had a significant impact on the lake's eutrophication and inferred lake-level changes.

Summary: By analyzing sediment cores from 11 shallow lakes in the Songnen Plain, northeast China, this study investigated the accumulation rates of organic carbon, total nitrogen, and total phosphorous over the past 150 years. The research found that nutrient accumulation rates in the lakes increased by approximately 2 times from the mid-19th century to the 1950s, and by approximately 5 times after the 1950s, due to increased anthropogenic impacts in northeast China.

Summary: This study investigated two lakes at different elevations in the Ecuadorian Andes and found that trace element fluxes are related to geology, erosion in the watersheds, and local point sources and atmospheric loads. The differences in fluxes between the two lakes were significant, with Lake Llaviucu being more heavily influenced by the city of Cuenca.

Summary: This study investigates the direct links between meteorological and limnological conditions and varve formation processes in Lake Zabinskie, showing the impact of air temperature on calcite laminae formation and primary production. It further demonstrates how lake mixing intensity influenced by wind activity and holomixis events lead to the formation of distinct manganese peaks in anoxic sediments.

Summary: The relationships between changes in meteorological conditions and diatom fluxes and taxonomic composition were investigated in two small lakes. The results showed that changes in meteorological conditions indirectly influenced diatom fluxes through changes in mixing regimes that affected nutrient and light availability. Statistical analyses demonstrated correlations between diatom data and air temperature and wind speed, although their influence on diatom assemblages was likely a surrogate for the complex changes in lake structure. Differences in specific diatom taxa succession and taxonomic composition were attributed to local conditions such as lake hydrological types, littoral zone extent, and sunlight exposure.

Summary: The reconstruction of submerged palaeolandscapes and detection of settling surfaces along coastal zones has become a significant research topic in the past two decades. The WASA project utilized a multidisciplinary approach to define the extent and characteristics of Late Pleistocene to Holocene deposits in the central Wadden Sea region. By using sub-bottom transects and sediment cores, the project was able to reconstruct stratigraphy and identify local sedimentary sequences. The WASA core catalogue has been successfully applied to review published data, define stratigraphic sequences and spatial extent, and reconstruct coastal paleoenvironments in the region.

Summary: Varved lake sediments are important archives for paleoclimatic information, but quantitative reconstructions based on biogeochemical composition are rare due to complexity. Recent advancements in high-resolution imaging and elemental mapping allow for better understanding of varve formation processes and climate-proxy relationships. This study presents a geochemical dataset from Lake Zabinskie, Poland, analyzing how seasonal meteorological conditions influence sediment composition and varve types, with the use of generalized additive models for climate inference.

Summary: This study examined the impact of Pleistocene strata deposits on the evolution of Holocene tidal inlets in the Wadden Sea region. Through core analysis and cross-sectional studies, new aspects of Pleistocene palaeoenvironments were uncovered. The presence of Elsterian tunnel valleys below islands, the partial erosion of Eemian tidal flats, and the limiting role of Saalian moraines in channel development were significant findings.

Summary: Traditional methods of sediment facies discrimination rely on observer-dependent descriptions and cannot be easily reanalyzed. Quantitative laboratory measurements can overcome this limitation but are time-, labor-, and cost-intensive. This study evaluates the potential of combining non-destructive down-core scanning techniques for automated supervised facies classification, providing a novel approach towards reproducible and quantitative analyses.

Over the past 6000 years, the area has seen a diverse landscape transformation from peat bogs to freshwater lakes, and eventually to salt marshes.

Summary: AMS radiocarbon dating of shells near the island of Wangerooge in AD 1889 yielded a new local correction factor Delta R of -85 +/- 17 C-14 years for the Wadden Sea area. The study found that the incorporation of C-14-depleted terrestrial carbon into shell material contributes to the higher values, and highlighted the need for further research on bivalve shell preservation dynamics and the reintroduction of Mya arenaria into European waters.
