These include the Southern Ocean (one of the few areas not already heavily fished) and the productive fishery off the coast of Peru and northern Chile, where upwelling from the deep brings nutrients to the surface, but which is already quite acidic.

The Economist

Upwelling in coastal waters brings nutrients toward the surface.

Encyclopedia Britannica

The Ross Sea is strongly influenced by the coastal East-Wind Drift that sets up a vast clockwise gyre accompanied by deepwater upwelling.

Encyclopedia Britannica

During the southwest monsoon, upwelling occurs off the Somali and Arabian coasts and south of Java.

Encyclopedia Britannica

The most productive waters of the world are in regions of upwelling.

Encyclopedia Britannica

In the High Arctic, upwelling currents result in open water areas within the pack ice called polynya; these enable seabirds to feed and nest at latitudes above 75° N. The flora of Antarctica consists mainly of soil and freshwater algae, lichens, mosses, fungi, and only two native species of vascular plants.

Encyclopedia Britannica

Specifically, volcanic carbon dioxide is known to depress the carbon-14 level of nearby vegetation, and dissolved limestone carbonate occasionally has a similar effect on freshwater mollusks, as does upwelling of deep ocean water on marine mollusks.

Encyclopedia Britannica

Off the west coasts of the American continents in the trade-wind belts, upwelling of cold subsurface water causes the overlying air to be cooled below its dew point (the air temperature below which water vapour condenses as dew), with the consequent widespread formation of low, thick clouds.

Expert writing Tips

Best practice

When describing marine ecosystems, use "upwelling" to highlight the nutrient-rich water rising to the surface, supporting abundant marine life.

Common error

Avoid attributing "upwelling" solely to temperature differences; it's primarily driven by wind patterns and the Coriolis effect, which then influence water temperature and nutrient distribution.

Linguistic Context

The term "upwelling" primarily functions as a noun, referring to the process of water rising from the deep ocean to the surface. This is supported by Ludwig and is frequently observed in scientific and encyclopedic contexts.

Ludwig's WRAP-UP

In summary, "upwelling" is a well-established term predominantly used as a noun to describe the process of deep ocean water rising to the surface. Ludwig's analysis confirms its common usage across encyclopedias, news media, and scientific publications. The process is critical to marine ecosystems, delivering vital nutrients that support a wide range of marine life. While primarily encountered in formal scientific contexts, "upwelling" also features in news reports concerning environmental and economic impacts, as showcased in Ludwig.

FAQs

How does "upwelling" affect marine ecosystems?

"Upwelling" brings nutrient-rich water from the depths to the surface, fueling phytoplankton growth and supporting complex food webs. This process often leads to highly productive fisheries.

What causes "upwelling" in coastal regions?

Coastal "upwelling" is typically caused by winds blowing parallel to the coast, combined with the Coriolis effect, which moves surface water offshore, allowing deeper water to rise and replace it.

Where are some of the most significant "upwelling" regions in the world?

Some of the most significant "upwelling" regions include the coasts of Peru, California, and Northwest Africa. These areas are known for their high marine productivity and support major fisheries.

What happens if "upwelling" fails?

If "upwelling" fails, the supply of nutrients to surface waters is cut off, leading to a decline in phytoplankton populations and disrupting the entire marine food web, potentially causing widespread ecosystem collapse.
