Sentences with phrase «submarine groundwater discharge»

The recharge - discharge imbalance can be reconciled if water cycle budgets included the difficult - to - measure rates of prolific submarine groundwater discharge (SGD).

If fresh submarine groundwater discharge approaches just 7 % of the total SGD, it would not only balance current groundwater recharge, but would steadily raise sea level by an additional 2 mm / year, even if there was no ocean warming and no melting glaciers.

Moosdorf (2017) has reviewed the locations and many human uses of fresh submarine groundwater discharge around the world.

The shallow coral reefs off Kahekili, West Maui, are exposed to nutrient - enriched, low - pH submarine groundwater discharge (SGD) and are particularly vulnerable to the compounding stressors from land - based sources of pollution and lower seawater pH. To constrain the carbonate chemistry system, nutrients and carbonate chemistry were measured along the Kahekili reef flat every 4 h over a 6 - day sampling period in March 2016.

A research led by the UAB demonstrates the importance of submarine groundwater discharge as a source of nutrients for the marine ecosystems of the Mediterranean Sea.

The study can help researchers identify which variables of topography and climate drive submarine groundwater discharge, says Robert Buddemeier, a geohydrologist at the Kansas Geological Survey in Lawrence.

When this water, called submarine groundwater discharge (SGD), trickles through contaminated soil and rock, it can pick up and transport a variety of ions, nutrients, and chemicals to the sea — including pollutants that contribute to coastal dead zones and toxic algal blooms.

Groundwater that seeps into the coastal zone beneath the ocean's surface — termed submarine groundwater discharge (SGD)-- is an important source of fresh water and nutrients to nearshore coral reefs throughout the globe.

Not exact matches

However, with improving techniques, researchers recently estimated total submarine groundwater (saline and fresh water combined) discharges suggesting a rate 3 to 4 times greater than the observed global river runoff, or a volume equivalent to 331 mm / year (13 inches) of sea level rise.
