Human activities have long been recognized for their detrimental effects on Earth’s surface, such as greenhouse gas emissions and deforestation. However, a recent study conducted by hydrology researchers from the University of Arizona sheds light on how these activities also impact Earth’s deep subsurface, a region lying hundreds of meters to several kilometers beneath the

The Nile River has long been a source of contention among the 11 countries it flows through in East Africa. Issues surrounding water access, energy production, environmental concerns, and cultural significance have created tensions that often overshadow opportunities for collaboration and mutual benefit. However, a recent study conducted by The University of Manchester, in collaboration

Rivers are dynamic natural features that shape the landscape through their movement. A recent study conducted by researchers at UC Santa Barbara delves into the factors that drive the migration rates of meandering rivers. Lead author Evan Greenberg and senior author Vamsi Ganti compiled a global dataset of meandering rivers to analyze how vegetation and

Oases play a crucial role in sustaining life in dryland regions, providing water sources for human populations, plants, and animals. Despite covering only about 1.5% of the world’s land area, oases support 10% of the global population. These wet refuges have been under threat from climate change and human activities, which have led to significant

Submarine slides are common triggers for tsunamis, especially when caused by factors such as earthquakes, volcanic activity, or sediment flux. Megaslides, however, are extreme versions of these underwater events that can have significant impacts on the surrounding areas. One such megaslide occurred in the Surveyor Fan in the Gulf of Alaska about 1.2 million years

In recent years, mooring observations and hydrographic data have revealed a concerning trend in the North Atlantic. According to a study published in the journal Nature Geoscience, the Atlantic Meridional Overturning Circulation – specifically its deep water limb – has experienced a significant weakening. This weakening, estimated at around 12% over the past two decades,
