In a remarkable discovery, Norwegian archaeologists are uncovering ancient treasures as glaciers shrink, revealing 48 prehistoric arrows, including one dated between 5,000 and 6,000 years. This influx of artefacts signifies a shift in our understanding of prehistoric activities as ice melts in the region. The urgency of recovery efforts underscores the impending deterioration of these valuable pieces, highlighting the rapid loss of ice cover around the world.

A new restoration strategy has been proposed to address the environmental impacts of the Plymouth Mill in North Carolina. This plan highlights essential actions such as conserving wetlands and restoring natural habitats along the lower Roanoke River. A significant portion, 760 acres of wetlands, will be preserved through a conservation deed. The initiative plans to utilize about $1.

Researchers restored woody habitat along a 110-km section of Australia's Murray River by adding 4,450 timber structures. Over seven years, Murray cod numbers tripled and golden perch numbers doubled in the restored reach, with fish movement from connected source populations also contributing to the increase.

Researchers utilized fluorescein dye in the Rockall Trough to study deep ocean water upwelling. They measured rapid upward movement reaching about 125 metres per day, significantly faster than average estimates. This study provides direct observations of upwelling in submarines canyons, offering insights into ocean circulation dynamics. Findings suggest underwater topography plays a crucial role in deep-water circulation processes. Future research aims to explore similar processes in different submarine canyon settings.

Researchers created paver tiles using discarded PET plastic, eggshell powder, and river sand instead of cement. They tested various combinations to determine the best proportions for mechanical strength and performance. The optimal mix included 70% PET, 20% eggshell powder, and 10% river sand, resulting in suitable tiles for pedestrian use. Microscopy revealed strong bonding within the composite structure, enhancing durability.

The Moab Uranium Mill Tailings Remedial Action Project has efficiently relocated 17 million tons of waste from the riverbank. Following rail transportation, teams are actively monitoring groundwater contamination levels. Upcoming efforts will also involve excavating contaminated soil near the original tailings site. The objective is to guarantee long-term safety and stability for local residents and the ecosystem. Ultimately, regrading and revegetating the area will be crucial in preventing future erosion.

After nearly two decades of planning, construction is underway in downtown Grand Rapids to restore the historic rapids that gave the city its name. The first phase will remove four low-head dams and replace them with natural rock features designed to improve fish passage, habitat and river access. The project also includes measures to protect mussels and control invasive sea lampreys.
