Greenland ' smeltwater may fertilize fjords with phosphorus

Greenland Glacier Melting

FjordsWhat is the meaning  
Basic explanation

N. Fjord, Coast Xiajiang (fjord noun plural)

PhosphorusWhat is the meaningEnglish tone [? F?sf?r?s]
American Sound [? Fɑ:sf?r?s]
Basic explanation

N. phosphorus [P]; phosphor

The massive Icesheet topping Greenland is losing nearly for billion tons a year to melting and according to NASA estimates. And all that melt water means rising seas. But it's also dumping huge amounts of nutrients and minerals into Arctic waters.

Ice Sheet[Ground] ice sheets; Ice shields.
ToppingWhat is the meaningEnglish Tone [' t?p??]
American Sound [? tɑp??]
Basic explanation

N. Something that constitutes a top; a decorative ingredient on a pastry.

dumpingWhat is the meaningEnglish tone [? d?mp??]
Basic explanation

N. Dumping
v. To dump (a current participle of a dump);

GlaciersWhat is the meaningEnglish Tone [ɡ ' L?s?? Z]
American Tone [ɡ ' l?s?rz]
Basic explanation

N. Ice, Glacier (glacier noun plural)

NASA estimates that the massive ice layer on the Greenland surface is disappearing at a rate of 300 billion a year. Melting ice means rising sea levels. But there will also be plenty of nutrients and minerals going into the Arctic waters.

"The great thing about glaciers and ice sheets, was that they ' re these big, very heavy systems, and as they move over rock They grind and crush the rock up. "

Move over move away

Crush up
Crush To knead into a group; Crushed

Basic explanation

adj. Bio-geochemistry

' So they expose ' allthese reactive kindof traces components of the rock lattice ' to ' thefresh melt water that ' s coming in. 】 ”

The great thing about glaciers and ice is that they are huge, massive, and can move rocks and shatter them. Joen Hocking is a glacier geologist at the University of Bristol, UK. "So the abundance of trace elements in the rock will go into the melted snow. ”

That's meltwater funnels rock dust into Greenland's glacial rivers, where Hawkings and his colleagues took their samples. They found that Greenland ' s rivers is much richer in phosphorus than previously believed.

FunnelsN. Funnel (plural of funnel)

The melted ice water filtered the dust from the rocks and eventually became the Glacier River in Greenland, where Hawking and his colleagues sampled. They found that the amount of phosphorus in Greenland's rivers was very rich compared to previous guesses.

And they estimate that Greenland ' s glacial rivers could flush some 400,000 tons of phosphorus into ocean waters every year-t Hat's on par with the amount of phosphorous dumped to the ocean by the Mississippi or Amazon rivers. The findings appear in the journal Global biogeochemical Cycles.

Flush [fl??]N. Agitation, overflowing, red, sprouting, flourishing, rushing
Vt. to cause to flush; flush with water; to make the excitement.On par with

• And... Same level

They estimate that the Glacier River in Greenland will inject about 400,000 tonnes of phosphorus into the ocean each year--a number that is equal to the annual injection of Mississippi R. or the Amazon. The findings are published in the Journal of Global Biogeochemical Cycling.

All that extra phosphorus could is fertilizer for ocean life. "It's an essential nutrient for phytoplankton, who is the guys on the bottom of the food chain. So it's really, really important for life. and life can ' t exist without it. "

"All this extra phosphorus will be a fertilizer for marine life. Phytoplankton are at the bottom of the food chain, and phosphorus is an important nutrient. So, these are really important, without it, life cannot live. ”

runoffWhat is the meaningEnglish Tone [' r?n??:f]
American Sound [? r?n?? F,-?ɑf]
Basic explanation

N. A run-off vote; an additional race; runoff.

oxygenated[,? ksid?? N ' Eitid]Adj, oxygenated, filled with oxygen;
V. Making oxygenation (oxygenate of past participle); oxygenation

The glacier grinds the rock and it melts and flushes the nutrients into the sea-something that is not uncommon. In fact, the authors estimate that in the past extreme ice ages – the snowball hypothesis 700 million years ago – these phosphorus runoff could lead to a lush ocean life. The flourishing of life eventually leads to the emergence of aerobic organisms on Earth, which lays the foundation for the production of our human beings.
