Summary: The Winter Storm Outbreak of February 2021 caused a significant cooling of the Gulf of Mexico, resulting in extensive marine life loss. By analyzing multiple datasets, this study aims to improve our understanding of the impact of winter storms on the ocean.

Summary: Short-term increases in stream temperature in response to storm events in urban areas are influenced by factors such as pre-event conditions, rainfall-runoff characteristics, and the shape of the hydrograph. Understanding these factors has important implications for urban hydrology and identifying different water sources and pathways in urban catchments.

Summary: The study reveals that changes in winter conditions can have significant impacts on summer phytoplankton biomass and production in lakes, with earlier snowmelt in the watershed leading to lower summer chlorophyll-a concentrations. The results suggest a strong negative correlation between runoff timing and summer chlorophyll-a concentrations.

Summary: In this study, the origin of precipitation generated by a severe winter storm in 1993 was investigated. It was found that most of the moisture came from the western North Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico. The moisture contribution from oceanic sources was higher than terrestrial sources, and the moisture sources shifted northward as the storm moved. The uptake of moisture mainly occurred in the cyclone-anticyclone interaction region.

Summary: Major climatological changes occurred during the 1990s worldwide. In the Northern Hemisphere, the winter decadal change was more rapid than in summer, with strengthened lower-tropospheric anticyclones over the subtropical Pacific Ocean and a northward shift of the midlatitude westerly jet stream. This led to the expansion of convection in Southeast Asia and dry conditions in North Africa and West Asia. In boreal summer, the westward shift of the Asian monsoon and northward penetration of the African monsoon were associated with weakened westerly flows.

Summary: River networks play an important role in transporting dissolved organic carbon (DOC) from land to the coastal ocean. The uptake of DOC in a river network is influenced by factors such as stream order, seasonal conditions, and flow. However, the dominance of biological or abiotic processes in DOC uptake and the partitioning of uptake between lakes and rivers are still unclear. In this study, a new model named CUPS-OF-DOC is presented to quantify DOC cycling in a river network, taking into account river-lake connectivity. The model is applied to the Connecticut River Watershed, revealing that the proportion of DOC uptake from photomineralization varies across different flow conditions and stream orders.

Summary: This study examined the diversity, spatial and temporal distribution, and structure of ichthyoplankton assemblages in the Beibu Gulf. It identified the major environmental variables affecting the assemblage structure and provided valuable information for conserving fish spawning grounds and developing fishery management practices in the area.

Summary: The Qinzhou Bay, a semi-enclosed bay, is facing environmental pressure from fast-growing industrial and aquacultural development. This study used microscopic examination and CHEMTAX analysis to investigate the spatiotemporal variability of the phytoplankton community in Qinzhou Bay. The results showed that temperature, nutrient availability, and selective grazing of oyster influenced the succession of phytoplankton community, and eutrophication, selective grazing of oyster, and warming were the driving factors of long-term changes in phytoplankton composition in Qinzhou Bay.

Summary: Winter burning is more beneficial for improving the nutritive value of Gulf cordgrass and seacoast bluestem compared to summer burning. Gulf cordgrass has similar crude protein (CP) levels following burning in both seasons, but CP increases more quickly following winter burning. Seacoast bluestem shows little change in CP following summer burning.

Summary: This study utilizes satellite-based sea surface temperature (SST) images to investigate novel aspects in the physical oceanography of the Baltic Sea, including marine heat waves (MHWs), the combined impacts of MHWs and coastal upwellings (CUs), and winter upwellings. The research reveals that the record-breaking MHW of the summer 2021 was interrupted multiple times by CUs, resulting in variations of 15-20 degrees Celsius in SST. Additionally, it highlights the presence of winter upwelling as a frequently occurring yet understudied phenomenon in the Baltic Sea, contributing to longer ice-free periods and slightly higher water temperatures along the Estonian coast compared to the Finnish coast.
