羅斯冰架(英语:Ross Ice Shelf)是世界上最大的冰架,位於南極洲的愛德華七世半島和羅斯島之間,東西長約800公里,南北最宽約為970公里,冰架靠海邊緣高60米,接近陸地的邊緣,最厚有750米,冰架面積約52萬平方公里,差不多等於一個法國那麼大,四周冰壁陡峭。
理查·伯德(Richard Byrd)的著名冒險日誌《獨自一人》(Alone)的背景環境,就是羅斯冰棚。
冰架的發現
1841年,英國海軍探險隊乘坐兩艘三桅木船,穿過通南極洲的太平洋看冰區,企圖確定地球南磁極的位置,4天後,他們駛出浮冰區,以為前邊暢通無阻,不料,他們遇見一堵巨大的冰壁,擋著了去路,探險隊長羅斯爵士驚呼道:“要穿過這道冰壁犹如穿越多佛懸崖,絕無可能”這座冰架後來就以他的姓氏命名。
