Summary: Shorewatch, managed by Whale and Dolphin Conservation (WDC), is a citizen science project that records occurrences of cetaceans along the coast of Scotland. The project has provided valuable information about seasonal, geographical, and year-to-year differences in cetacean occurrence through over 11000 sightings of at least 18 species between 2005-2018.

Summary: This study introduces a new statistical approach to predict the occurrence frequency of peak-season tropical cyclones in the South China Sea and east of the Philippines, based on pre-seasonal environmental fields. The identified predictors capture the interannual variability of different types of peak-season tropical cyclones, providing skillful seasonal predictions. The statistical approach is further developed into a hybrid method using predictors derived from dynamical seasonal forecasts, which shows significant skill for both regions. The statistical and hybrid predictions outperform the dynamical predictions, indicating their potential for operational use.

Summary: The management of groundwater resources requires considering their variation trends. This study uses three statistical methods to identify seasonal and annual groundwater level trends in Eastern Romania. The results show that prolonged meteorological and hydrological droughts in the northern and central parts of the region have led to a decrease in groundwater depth.

Summary: Anthropogenic increase in atmospheric CO2 concentrations drives a global increase in ocean carbon sink, with strong temperature dependence dominating air-sea flux cycles in the southeast Florida region. Despite data distribution biases, there have been no significant changes in carbon uptake over the past three decades, emphasizing the importance of unbiased datasets for climate studies. Although not statistically significant to date, different seasonal responses over time may lead to seasonal amplification and decoupling between annual and seasonal means in the future.

Summary: The exploration of precipitation data using innovative analysis methods can offer significant contributions to various domains, such as water resources management, agricultural planning, climate change understanding, and risk assessment. This study employs an improved visualization method to detect annual and seasonal trends in precipitation variables across 194 stations in Turkey. The results show varying trends in different regions and basins, with some areas experiencing notable increases or decreases in precipitation. The innovative method provides more detailed results compared to traditional statistical tests, enhancing the accuracy of assessments and the effective management of water resources.

Summary: This study analyzes temperature changes in Europe from 1951 to 2020 based on data from 210 weather stations, finding a linear increase in temperatures since 1985. The greatest temperature rise is seen in spring, while summer displays the greatest stability. Overall, warming intensifies towards the northeast of the continent, with noticeable changes in winter and spring compared to summer.

Summary: This study assesses the trend and variability in rainfall characteristics that affect annual streamflow in southeast Australia. The results show a declining rainfall trend, with the most significant trend observed in the number of rainfall days and multi-day rainfall totals. Changes in rainfall characteristics also play a role in influencing annual streamflow.

Summary: Long-term precipitation monitoring is important for water resource management and disaster prevention. This study assessed the trends in seasonal and annual precipitation in Pakistan from 1960 to 2016 and found that, overall, there was an increasing trend in precipitation. However, there were also regional and seasonal variations in the trends, with some areas experiencing a decrease in precipitation.

Summary: This study investigated the composition and relationships of bacterial and phytoplankton communities in the Pearl River Estuary. It found that bacterial community composition varied with size fractions and salinity gradient across seasons. The study also revealed that the differences between particle-associated and free-living composition were more significant in the wet season. Additionally, positive co-occurrences were observed between phytoplankton species and bacterial populations, indicating mutual cooperation.

Summary: This study examines the wind-wave climate data over a span of 41 years to analyze the characteristics and trends of wind-generated waves. The results indicate significant changes in wave activity at specific locations during different time periods, highlighting the importance of understanding and simulating wind-wave changes for effective coastal management, environmental impact assessments, and sustainable development.

Summary: The study explores the vegetation-temperature relationship on the Tibetan Plateau by analyzing air temperature, vegetation, and land surface temperature (LST) patterns using various datasets. The findings reveal a significant greening response in NDVI during the spring and autumn seasons, with earlier breakpoints and more sensitivity in recent warming phases. Both MODIS and GIMMS data show an increase in NDVI on the Tibetan Plateau for all timescales, with MODIS exhibiting a larger greening area since 2000. Trends in NDVI and LST are most prominent in spring and autumn, respectively, and significant variations in NDVI and LST mostly occur in winter and autumn. The partial correlation analysis reveals a negative impact of NDVI on LST at the annual scale and in autumn, and a positive impact in spring. These findings enhance our understanding of vegetation-climate relationships at annual and seasonal scales.

Summary: Multiple blue whale acoustic populations exist in the Southern Hemisphere, with Antarctic blue whales overlapping with pygmy and Chilean blue whales during their migration. Despite this overlap, each subspecies showed distinct seasonal patterns in detections. Further research into the migration patterns of these whales will provide insights into how they continue to remain separate.

Summary: Research indicates that the prevalence of wasting in India is higher than international standards, and seasonal bias can affect survey results, requiring special methods for analysis. Regression models show seasonal variation in wasting throughout the year in India, but direct comparisons across surveys should be avoided to prevent biased estimates.

Summary: This study found multiple antibiotic resistance genes in rural rivers, with sul1, sul2, and int1 being the dominant target genes in water samples. The distribution of ARGs is affected by different seasons and spatial locations, suggesting that pollution of antibiotic resistance genes by rural activities must be a concern.

Summary: Gas and particle samples were collected from southeast coastal and mountainous cities in China to analyze the levels and characteristics of perfluoroalkyl acids (PFAA). PFAA concentrations varied in the ranges of 7.8-290 pg/m³ in gas phase and 27-1200 pg/m³ in particulate phase, with perfluorobutanoic acid (PFBA) and perfluorooctanoic acid (PFOA) being the dominant compounds. The study found that PFAA distribution was influenced by particle size and the length of fluorinated carbon chain, with PFSAs preferring to distribute on coarse particles and long-chain PFAA tending to exist in particulate phase. The Winter Monsoon was identified as a potential driver for atmospheric transport of PFAS to southern cities.
