Summary: This study aimed to investigate morphometric characteristics, assess soil erosion risk, and prioritize different sub-watersheds of the Koyna River basin in India using geospatial technology. Results showed that the basin has less flood hazard, moderate roughness, and unevenness, with a dominant parallel drainage pattern. The study also applied the Revised Universal Soil Loss Equation method to identify erosion-prone zones and found that most of the study area had very slight soil erosion vulnerability.

Summary: This study prioritizes sub-watersheds for the Peddavagu basin using five methods, primarily utilizing remote sensing and geographic information system techniques. Quantitative measurements of morphometric analysis, land use/land cover analysis, and linear discriminant analysis were used to rank and prioritize sub-watersheds. Based on these analyses, the sub-watersheds were classified as low, medium, and high priority, with SW10 identified as high priority. Decision-makers in the research region can use these findings for watershed management planning and implementation.

Summary: Flood events in the Hars River Basin in the Eastern Black Sea Region of Turkey were discussed based on drainage basin morphometry using three different methods. Results showed varying flood priorities based on morphometric parameters, and the accuracy of priorities obtained using the RPRM and PCA methods were higher than the MA method. Common sub-basins with similar flood risk were compared with recorded flood maps of Turkey, validating the results obtained from the different techniques.

Summary: The study utilized GIS and remote sensing to analyze the morphometric characteristics of Gilgel Abay watershed, revealing it to be a fifth-order basin with 662 drainage networks. The stream length decreases with increasing stream order, and the high bifurcation ratio indicates mountainous terrain and susceptibility to flooding. The low drainage density suggests high permeability and dense vegetation cover.

Summary: The study on the hydrogeochemistry of groundwater in the Kallada River Basin in South India revealed rock-water interaction processes and major ion concentration changes, providing significant insights into the hydrogeochemical processes in KRB. The dominant groundwater types and geochemical associations varied spatially and temporally, highlighting the complex hydrogeochemical characteristics of the region. The pre-monsoon water types were Ca2+-Mg2+-Cl- while post-monsoon saw a shift to Na+-Cl-, with deeper wells showing a consistent Na+-Cl- water type throughout the seasons.

Summary: The Weddell Sea is experiencing changes in sea-ice extent due to ongoing climate change, with significant increases in the austral summer but decreases in the spring over the last four decades. Variability in seasonal sea-ice concentration is linked to thermal differences and westerlies intensification, affecting the Weddell Gyre. The study highlights the relationship between sea-ice variability and ocean-atmospheric forcings, emphasizing the need for continuous monitoring.

Summary: Global overturning circulation in the Arabian Sea, northwest Indian Ocean, during the past 136 ka shows significant variations in water mass sources, with more flow of Antarctic Bottom Water (AABW) during the glacials and North Atlantic Deep Water (NADW) during the interglacials. The Arabian Sea receives a higher fraction of AABW compared to the equatorial Indian Ocean during the interglacials, indicating differences in deep water exports from the Southern Ocean. The findings have important implications for regional biogeochemical processes, paleo-redox conditions, carbon sink, and atmospheric CO2 variability during glacial-interglacial climate transitions.

Summary: Antarctic sea ice expansion and recession are asymmetric and have regional and temporal variations. The lowest sea ice extent record in February 2022 is attributed to the ongoing sea ice recession since September 2021. The intensified Amundsen Sea Low and positive phase of the Southern Annular Mode play a crucial role in causing the decrease in sea ice extent.

Summary: This study utilized ten-year satellite derived data to investigate the variability of Chlorophyll-a, sea surface temperature, and net primary production in the eastern Arabian Sea. The relationship between NPP and SST showed changes over time, with the Arabian Sea being most productive during the summer monsoon period. However, there has been a recent decline in NPP, potentially attributed to extreme events such as cyclones along the west coast of India.
