Freshened Groundwater in the Sub-seafloor

Offshore freshened groundwater (OFG) is water hosted in sediments and rocks below the seafloor. It can be found offshore of most continents around the world and could possibly become a source of potable water for human populations living near the coast. A recent article in Reviews of Geophysics describes a range of geochemical, […]

A global assessment of the impact of groundwater on ocean chemistry is important for understanding the weathering of rocks and its effects on climate — ScienceDaily

An invisible flow of groundwater seeps into the ocean along coastlines all over the world. Scientists have tended to disregard its contributions to ocean chemistry, focusing on the far greater volumes of water and dissolved material entering the sea from rivers and streams, but a new study finds groundwater discharge plays a more significant role […]

New analysis highlights importance of groundwater discharge into oceans

IMAGE: Coastal groundwater discharge can sometimes be seen at low tide as rivulets flowing into the ocean, as on this beach on Oahu. A global assessment found groundwater discharge plays a… view more  Credit: Jenny Bernier An invisible flow of groundwater seeps into the ocean along coastlines all over the world.

Evaporation Reverses Groundwater Flow and Forms Hyper-Salinity

The exchange of fresh water between a river and its floodplain can be altered by evaporation by lowering the water table and by increasing salt concentration. The rate of evaporation is affected by atmospheric demand for water, which is anticipated to increase with climate warming. America et al. [2020] use a numerical modeling […]

Modeling Groundwater and Crop Production in the U.S. High Plains

An international team of more than 2 dozen researchers has found a novel approach to modeling groundwater levels and crop production to forecast future resource availability and yields. The model the researchers developed was inspired by ecology’s Lotka-Volterra equations, a mathematical explanation for the cyclical population dynamics of predator and prey species. “We […]
