“深海”一词与每个人的含义不同。对于渔民来说,深海是相对浅的大陆架之外的海洋的任何一部分。对于科学家来说,深海是海洋中最低的部分,位于温跃层(太阳能加热和冷却不再产生影响的层)之下,并且位于海底之上。这是海洋深度超过1000 f或1,800米的部分。探索深度是很困难的,因为它们永远是黑暗的,极冷的(在0摄氏度到3摄氏度以下3000米之间)和高压(15750磅/平方英寸或比海平面标准大气压高1000倍)。从普利尼时代到19世纪末,人们相信深海是一片没有生命的荒地。现代科学家认为深海是地球上最大的栖息地。已经开发出特殊工具来探索这种寒冷,黑暗,加压的环境。深海探索是一项多学科的努力,包括海洋学,生物学,地理学,考古学和工程学

美国堪萨斯州地质学Essay代写:深海探索

The term “deep sea” doesn’t have the same meaning to everyone. To fishermen, the deep sea is any part of the ocean beyond the relatively shallow continental shelf. To scientists, the deep sea is the lowest part of the ocean, below the thermocline (the layer where heating and cooling from sunlight ceases to have an effect) and above the sea floor. This is the part of the ocean deeper than 1,000 fathoms or 1,800 meters. It’s difficult to explore the depths because they are eternally dark, extremely cold (between 0 degrees C and 3 degrees C below 3,000 meters), and under high pressure (15750 psi or over 1,000 times higher than standard atmospheric pressure at sea level). From the time of Pliny until the end of the 19th century, people believed the deep sea was a lifeless wasteland. Modern scientists recognize the deep sea as the largest habitat on the planet. Special tools have been developed to explore this cold, dark, pressurized environment. Deep sea exploration is a multi-disciplinary endeavor that includes oceanography, biology, geography, archaeology, and engineering.
