But a sudden influx of fresh water from melting ice could also disrupt the ocean currents that drive upwelling.
“海洋生态系统是由多种资源孕育而非单一依靠冰川，”胡德说，“例如，洋面上升是一种自然循环现象，富含养分的冷水从海底升起，滋养了海面的生物。 但是，由于冰川的融化而导致大量淡水突如其来涌入海洋，这可能会破坏洋流的正常循环。”
The Great Lakes comprise the largest collective body of fresh water on the planet, containing roughly 18 percent of Earth's supply. Only the polar ice caps contain more fresh water.

The key here is the availability of liquid water: Despite the fact that Antarctica is home to most of the Earth's fresh water, most of it is locked up in ice.
这里的关键因素是液态水的供应，虽然南极洲拥有地球大部分淡水，但其中大部分以冰的形式被锁起来。
Variations in the salinity of ocean waters depend on the addition or removal of fresh water through evaporation and precipitation and, in polar regions, on the freezing and melting of ice.
海水盐度的变化依赖于通过蒸发和凝结而增加或减少淡水，在极地地区则依赖于冰的冻结和融化。
Argument exists over whether slowdowns are primarily wind-driven, or could be caused by an influx of fresh water from melting ice sheets.
围绕着环流的减速主要是由风力造成的，还是由冰盖融化后大量淡水的涌入引起的，出现了两种不同的观点。
If the Greenland ice sheet disappeared sea levels around the world would rise by seven metres, as 10% of the world's fresh water is currently frozen here.
如果格陵兰冰盖消失，世界各地的海平面将升高七米——因为现在世界10%的淡水都被冻结在这里。
But rising temperatures have set off a worldwide thaw of many glaciers and ice sheets, which collectively act as the second largest reservoir of Earth's fresh water, Hood said.
但是，由于气温不断上升，构成地球第二大淡水水库的冰川和冰层有逐渐消融的态势。
Of the remaining 2.5 percent that is fresh water, about 69 percent is frozen in ice caps and glaciers.
在剩下的2.5%的淡水中，大约有69%是未融化的冰川和冰河。
Kwok said: "ice volume allows us to calculate annual ice production and gives us an inventory of the fresh water and total ice mass stored in Arctic sea ice."
Kwok称：“通过冰层的总量，我们可以计算出每年冰的产生量，并列出一份北极冰盖中所含有的淡水和冰总量的清单。”
Every year, thousands of cubic kilometres (km3) of fresh water fall as rain or snow or come from melting ice.
每年，雨雪和融冰所带来的淡水资源有几千立方千米。
Shake recipe with ice , strain over fresh ice and top with soda water.
加冰摇合所有原料，滤入冰块，注入适量苏打水。
Shake all ingredients except soda water with ice, strain over fresh ice and top with soda water. Purists insist Collinses should be stirred, but a shaken Collins has far more flavour.
除苏打水外加冰摇合原料，滤入冰块注入适量苏打水。纯味的柯林斯应该被搅合，但是摇合柯林斯会使酒更有风味。
Shake with ice, strain over fresh ice and top with soda water.
加冰块摇合原料，滤入冰块，注入适量苏打水。
So we can infer that the aim of the periodicity of Ice Age is to store up fresh water for all living things on the earth.
因此我们可以推断：冰河期产生的目的一定是为地球上的所有生物蓄积足够的淡水。
Triton 's fountains of youth are thought to be volcanoes that erupt a cold lava of water and liquid ammonia, which freeze to cover the surface with fresh ice and erase the signs of age.
特里同上年轻的喷泉被认为是在过去喷发低温岩浆和液态氨的火山，这些岩浆和液态氨结成冰包裹表面，抹掉了年龄的印记。
Other genius touches: an ethylene filter in the produce drawer keeps your veggies fresh longer, and the tall ice and water dispenser accommodates bottles and pitchers.
其他天才特色：水果蔬菜抽屉里的一个乙烯过滤器使您的蔬菜在更长时间里保持新鲜；高高的冰水分配器用来容纳瓶罐。
On top of that, nearly 90 per cent of all the fresh water is ice and snow, and sitting in polar regions or on high mountains where it's difficult for people to reach.
除此之外，将近90%的淡水都以冰雪的形式存在于极地或高山之巅，人类难以涉足之处。

在分析上述淡水冰破坏机理的基础上，对试验结果进行研究。
The results show that flexural strength of fresh water ice is closely related to stress rate and temperature.
结果表明，水库淡水冰弯曲强度与应力速率和冰温有着密切关系。
The thinner fresh-formed ice was also more vulnerable to melting from heat held near the ocean surface by clouds and water vapor.

Antarctica has deep fresh water lakes beneath the ice, with lake Vostok the largest, as large as lake Ontario.
南极洲冰川之下有很深的淡水湖，东方湖是最大的，像安大略湖一样大。
The water of the Baltic is not very salty because many fresh rivers flow into it, so it freezes more easily. Many of its ports are blocked by ice in winter.
另外一个原因是有不少淡水河流入波罗的海，造成该海的含盐度较低，冬季容易结冰。
