An international team has discovered a fast-moving deep ocean current near Antarctica that may help researchers monitor the impact of climate change on the world's oceans.
一個國際小組已發現一快速移動的深層洋流在南極洲附近,可能幫助研究人員在世界各大洋監測氣候變化的影響。
The Australian and Japanese scientists who found the current say it has the volume of 40 Amazon Rivers and is the fastest deep ocean current ever found.
發現洋流的澳洲和日本科學家們說,它具有 40條亞馬遜河的體積,是有史以來發現的最快深層洋流。
According to a study published in the journal Nature Geoscience, the current is a key part of a global ocean circulation pattern that helps control the planet's climate.
據一項在自然地球科學期刊發表的研究,水流是一全球海洋環流模式的關鍵部分,有助於控制地球的氣候。
It moves at an average of 20 centimeters per second, carrying over 12 million cubic meters of Antarctica's dense, oxygen-rich water every second, Steve Rintoul of the Antarctic Climate and Ecosystems Cooperative Research Center told Reuters.
它移動平均每秒二十糎米,每一秒攜帶超過 12萬立方米的南極的密集、富氧水,南極氣候和生態系統合作研究中心的史蒂夫林托爾告訴路透社。
Rintoul explained that the current carries the water to the deep ocean basins around the Kerguelen Plateau in the southern Indian Ocean where it branches out.
林托爾解釋,水流携帶水至南部印度洋凱爾蓋朗高原周圍的深海盆地,它在那地方分流。
This way it forms part of a much larger network, which distributes heat through the world's oceans.
以這方式它組成一個更大的網絡的部分,分佈熱力至世界各大洋。
"The deep current along the Kerguelen Plateau is part of a global system of ocean currents called the overturning circulation, which determines how much heat and carbon the ocean can soak up," Rintoul said.
