Sediment eroded from continents during ice ages can be rapidly (<104 years) transferred via rivers to the deep-sea and preserved in submarine fans, becoming a viable record of landscape evolution. We applied chemical weathering proxies and zircon geo-
Increasing industrialization in the 19th century spurred that growth, with the development of electric power and steam engines resulting in factories no longer needing to be located near rivers. Instead, they could be in urban areas, drawing even more people into those cities with the promise of ...
The Arctic Ocean is unique with respect to its high freshwater input from the Siberian and North American rivers (11% of global river discharge), which not only influences circulation, stratification and deep water formation in the high northern latitudes1but also affects water column biogeochemistry...
