There are few upwellings in the tropics, which are thus nutrient-poor.

热带地区很少有上升流，因此缺乏硝酸盐。

They produce an upwelling effect, drawing nutrients up from deeper water towards the surface.

它们会产生上升流效应，将深水中的营养物质吸向海面。

Upwelling is the process of cold seawater filled with nutrients rising up from the deep.

上升流是指充满营养物质的冷海水从深海上升的过程。

They've already shown that the hurricane caused currents and upwellings deep into the twilight zone.

他们已经表明，飓风导致了暮光区深处的水流和上升流。

Proponents, conversely, see these early efforts, at least, as simply restoring upwelling that has been suppressed by climate change.

相反，支持者认为这些早期的努力，至少只是简单地恢复了被气候变化抑制的海水上涌。

Cooling the ocean surface by encouraging upwelling might also have a direct effect on the local air temperature.

促进海水上涌来冷却海洋表面也可能对当地气温产生直接影响。

However, the upwelling water doesn't always have all the nutrients these organisms need.

然而，上升流中的水并不总是含有这些生物所需的全部营养。

Indeed, for artificial upwelling to bring about that desirable state of affairs it may not even be necessary to farm seaweed.

事实上，人工上涌要想达到这种理想状态，甚至都不需要养殖海草。

Kelp likes the movement of the tide and the upwelling of nutrients that makes it very difficult to grow on land.

昆布喜潮汐运动 好营养物质上涌，这种特性使其难以在陆上生长。

However, the upwelling water doesn’t always have all the nutrients these organisms need.

然而，上升流水并不总是 含有这些生物所需的所有营养。

Along the coastline of the Atacama Region, there's what's called an upwelling system in the Pacific Ocean.

沿着阿塔卡马地区的海岸线，在太平洋有一个所谓的上升流系统。

This is a place where the upwelling of cold, dark Pacific currents lifts a bounty of sea life and mystery onto the shore.

此地因为冰冷且黑暗的太平洋洋流涌升，将许多海洋生物与海洋秘辛带到岸上。

In winter, there is almost no density difference in the North Atlantic and the Barents Sea—as you would expect given the upwelling there.

北大西洋和巴伦支海在冬天几乎不会出现水密度差—鉴于那里的上涌现象，人们会有所期待。

Those squeamish about anything that smacks of geoengineering-in other words, technology intended to change the world's climate in ways that oppose global warming-view artificial upwelling with scepticism.

那些对任何带有地质工程色彩的东西——换句话说，就是以反对全球变暖的方式来改变世界气候的技术——过于拘谨的人，都对人工上涌持怀疑态度。

Eventually, plants and animals will find these upwellings water and grow to create a miniature ecosystem, a microcosm of rich life, and in otherwise to avoid desert.

最终动植物会找到这些上涌的水，在此生长，形成一个微型生态系统，一个生物众多的小世界，也能避开沙漠。

Scientists think that an enormous upwelling of intense heat, a mantle plume, is rising from the interior of the planet under this part of the Rift Valley.

科学家们认为，一股巨大、酷热的上涌热源——一股地幔熔岩流，正在地球的内部，在裂谷的这块区域升起。

Without this action, which scientists call upwelling, the world would be even hotter than it has become as a result of human-caused emissions of carbon dioxide and other heat-trapping gases.

如果没有这一被科学家称为上升流的运动，由于人类排放二氧化碳和其他吸热气体，世界将比现在更热。

Ocean artUp, a project led by the Helmholtz Centre for Ocean Research in Kiel, Germany, is experimenting with the use of upwelling to encourage the growth of the small, planktonic creatures eaten by sardines.

由德国基尔亥姆霍兹海洋研究中心领导的“海洋艺术行动”项目，正在试验利用上升洋流来促进被沙丁鱼吃掉的小型浮游生物的生长。

Ocean artUp, which began in 2017 and is scheduled to run until the end of this year, has concentrated on simulating and measuring exactly how artificial upwelling affects the quantities of nutrients transferred between ocean layers.

“海洋艺术行动”于2017年启动，预计将持续到今年年底，主要致力于模拟和准确测量人工上涌如何影响海洋层间营养物转移的数量。

During neutral ENSO conditions, the trade winds blow westward against the surface of the Pacific Ocean, pushing warm water toward Indonesia and triggering the upwelling of cold water from the ocean's depths along the South American coast.

在中性 ENSO 条件下，信风向西吹向太平洋表面，将温暖的海水推向印度尼西亚，并引发南美海岸沿线海洋深处的冷水上涌。
