每日英語跟讀 Ep.K174: About Nature - Southern Ocean officially recognized by National Geographic

Anyone who thought the world had four oceans will now have to think again, after the National Geographic Society announced it would recognize a new Southern Ocean in Antarctica, bringing the global total to five.

認為世界上有四大洋的如今要再想想了。（美國）國家地理學會宣布，它將承認在南極洲的新「南大洋」，這樣一來，全球共有五大洋了。

The National Geographic, a non-profit scientific and educational organization whose mapping standards are referenced by many atlases and cartographers, said the Southern Ocean consists of the waters surrounding Antarctica, out to 60-degrees south latitude.

國家地理學會稱，南大洋由南極洲周圍的水域組成，向外延伸至南緯60度。國家地理學會是一個非營利科學與教育組織，許多地圖集和製圖師都參考該組織的製圖標準。

National Geographic Society geographer Alex Tait said scientists have long known that the waters surrounding Antarctica form a"distinct ecological region defined, by ocean currents and temperatures".

國家地理學會的地理學家亞歷克斯．泰特稱，科學家很早以前就知道南極洲周邊水域形成一個「由洋流和溫度界定的獨特生態區域」。

Tait told the Washington Post that the span of water is yet to be officially recognized as an ocean by the relevant international body: "But we thought it was important at this point to officially recognize it."

泰特告訴《華盛頓郵報》，相關國際機構尚未正式承認這片水域為海洋，「但我們認為此時正式承認它很重要。」

Australia’s largest dinosaur identified as new species 澳洲最大的恐龍被認定為新品種

A gigantic dinosaur discovered in Australia’s outback has been identified as a new species and recognised as one of the largest to ever roam the Earth, according to palaeontologists.

據古生物學家表示，在澳洲內陸發現的一種巨型恐龍已被認定為新物種，是曾在地球上出沒的體型最大恐龍之一。

The Australotitan cooperensis, part of the titanosaur family that lived about 100 million years ago, has finally been named and described 15 years after its bones were first uncovered.

「Australotitan Cooperensis」屬於泰坦巨龍家族，生活在距今約1億年前，距其骨骼首度被發現15年之後，終於得到正名及描述。

It is estimated to have stood at 5-6.5 metres high and measured 25-30 metres in length － which would make it Australia’s biggest dinosaur.

據推估，牠站立時身高可達5至6.5公尺，身長則為25至30公尺，是澳洲體型最大的恐龍。

"Based on the preserved limb size comparisons, this new titanosaur is estimated to be in the top five largest in the world," said Robyn Mackenzie, a director of the Eromanga Natural History Museum.

「根據存留下來的肢骨大小來推估，這種新的泰坦巨龍據估計是地球上體型最大的5種恐龍之一」，伊羅曼加自然歷史博物館主任瑪肯西說。

The fossilised bones were found on Mackenzie’s family farm in 2006 about 1,000 kilometres west of Brisbane in the Eromanga Basin.

2006年，在布里斯班以西約1000公里伊羅曼加盆地的瑪肯西家族農場中，發現這些骨骼化石。
