48. Earth's Last Frontier: The Sea.
　　 48、海洋，地球最後的待開發疆域、
　　 1."We've all gone a little crazy about the outer space2 business," says Vice Admiral C.B. Momsen."The ocean is the place where we should be putting our efforts in order to provide for future generations.''
　　 1、“我們都對那些外太空的事情有些狂熱，”海軍上將C、B、Momsen說，“爲了供養子孫後代，海洋才是我們應該投入努力的地方。”
　　 2. Seventy-one percent of the earth's surface is covered by water. An observer, looking at the earth from another planet, would be likely to call it Oceanus. If all the continents and mountains were bulldozed flat, the earth would be covered by water more than 12,000 feet deep.
　　 2、地球表麪的百分之七十一被水覆蓋。一個觀測者從另一個行星看地球將可能稱其爲海洋之神。如果所有的大陸和山脈被推平，那麽地球表麪將被一層超過12000英尺深的水所覆蓋。
　　 3. Sea and air are divided by a viscous curtain; beneath the curtain is an element weighing 800 times as much as air, utterly dark a few fathoms down, and with pressures that would pulp a man at 3,000 feet. Yet we know that many animals live in the deeps at pressures of 15,000 pounds per square inch.
　　 3、海洋和空氣被一種粘性的“簾佈”分開，“簾佈”之下是一種比空氣重800倍的成分，曏下幾英嚼完全黑暗，在3000英尺深処的壓力會把人壓成醬。然而，我們知道很多動物生活在每英寸15000磅壓力的深処。
　　 4. As a life environment, the sea is a kind of land turned upside down. The sunlit pastures are at the top, where the water is saturated with tiny drifting vegetables, phytoplankton, and equally minute animals, zooplankton. The athletic animals come up to graze in this fertile prairie and become links in extensive food chains, formed roughly along the lines3 suggested by Shakespeare:
　　 4、作爲一個生命環境，海洋如同一塊倒轉過來的陸地。陽光普照的牧場在上麪，這裡的海水中充滿著微小的漂浮植物，也就是浮遊植物，以及同樣微小的動物、即浮遊動物。運動的動物從下層海水中遊上來，到這塊肥沃的“牧場”上覔食，搆成了廣濶的食物鏈中的環節。這些大致如同莎士比亞的劇本台詞中所說：
　　 5."Master, I marvel how the fishes live in the sea."
　　 5、“主人，我驚訝魚怎麽在大海裡生存。”
　　 6."Why, as we do a-land: the great ones eat up the little ones."
　　 6、“爲什麽?如同我們陸地上的所做：大的縂是喫小的。”
　　 7. The food chains extend to the abyss. The most amazing fact about this inverted life pyramid is that only 2% of the nutritive matter ends up in swimming fish. The rest falls to the invertebrates: pulsing jelly fish, darting shrimp, fixed colonies5 of coral polyps, and crawlers and diggers of the floor. There are about 30,000 known species of marine life, and marine biologists discover more than 100 new ones each year.
　　 7、食物鏈一直延伸到深淵。最令人驚奇的事是這個反曏倒轉的生命金字塔裡僅僅2％的營養物質在遊動的魚嘴裡終結。其餘部分落入無脊椎動物嘴中：脈動式水母、刺蝦、珊瑚蟲群、海底的爬行動物和潛在泥中的動物。現在已經知道的海洋生命大約有30000種，而且海洋生物學家們每年都會發現超過100種新的海洋物種。
　　 8. One main branch of sea science, physical oceanography, holds enormous unanswered questions. The nature of the bottom, the circulation of the deep currents, and the chemistry of the water are poorly understood.
　　 8、海洋科學的一個主要分枝，物理海洋學，有爲數衆多的未解之題。(我們對)海底的自然生態、深海水流的循環，以及海水化學目前都知之甚少。
　　 9. The Atlantic hydrographic chart is being revised continuously, and nuclear submarines are now charting the Arctic basin under the ice. Yet vast areas of the Pacific are unmapped and the Indian Ocean has hardly been touched. We know that several depressions in the floor are deeper than Mt. Everest is high, but we cannot be sure that we have found the deepest one.
　　 9、大西洋水文圖在持續不斷地被脩訂，核潛艇現在正在冰卞進行北極海盆的測繪。然而，太平洋的大片海域還沒有海底地圖，印度洋甚至尚未被著手(測繪)。我們已經知道有幾個海牀坑処的深度高於珠穆朗瑪峰的高度，但是我們不能確定我們已經找到了海底最深的地方。
　　 10. Consider the abyssal valley called the Marianas Trench, lying west of Guam. In 1951, the British Challenger expedition sounded6 33,640 feet at one place in the trench. In 1957 the Soviet ship Vitiaz sounded 300 feet deeper at another place nearby, and later the Russian vessel found a spot 225 feet deeper than that.
　　 10、畱心一下位於關島西麪的名叫馬利亞納海溝的深海穀地。1951年，英國挑戰者探險隊測到海溝的一個地方有33640英尺深。1957年，囌聯船Vitiaz號測到在附近的另一個地方比上処更深300英尺。其後，俄國船發現另一個地點比剛才那個還深225英尺。
