Since ancient times, the Ocean has been the intellectual and imaginative challenge to
mankind, today, is still unknown territory, the last piece of the planet. Vast ocean to
explore the difficult, despite every effort of mankind, can only lift the veil on 12, even
if access to scientific and technological advances of the atomic age, the situation
remains largely unchanged. In 1860, the Mediterranean has cables need of repair, the
staff from 7200 feet deep where the cable one way or another surface, found that
cable covered with coral and other epiphytes animals, these creatures apparently from
the larvae, he had already attached to go up After several months or years to slowly
mature, less likely to pull in the cable before the process of Shanghai face wrap.
   In 1872, the world's first dedicated ocean exploration vessel vessel
Challenger (Chaue Lager) from England to conduct research around the world, the
ship again and again, casting a net, a few miles from the deep sea, covered with red
mud, and deep silence a dark area in the middle, pulled in many strange strange
creatures, dumped on deck. The first of these strange creatures to light, the past never
had seen such creatures, the Challenger's scientists carefully study,
understand that even in the most secluded and far-reaching sea, there are living
creatures.
   Recently found that a large majority of unknown bio-distribution in the global
ocean thousands of feet deep, which is human study of marine as the most exciting
discoveries over the years. In the first 25 years of the 20th century, came the echo
detection method, vessel to be recorded in the road during the depths, then probably
no one thought the technology could be used to study deep-sea biology. However, the
personnel operating the new equipment was found shortly after, to send out sound
waves from the ship as the beam as solid as long as the experience will be reflected
back. Some sound waves return from the ocean middle region, most likely because
fish encounter, the whale or a submarine before reflection; in these sound waves
return, the equipment to the bottom until it receives the reflected sound waves.
   To the late 1930s, human beings have been well aware of these facts, even the
fishermen began to discuss the search using the echo sounder fish. After the war broke
out, echo detection technology under strict security control, so no more relevant
information out. However, to 1946, the U.S. Navy issued an important announcement,
the disclosure of several scientists have been developing deep-sea sonar off the coast
of California, Yi Qi, they found a layer of deep-sea distribution in the vast area of the
object, sound waves will bounce back; this layer of the object seems to be Suspended
between the Pacific sea surface and seabed, an area of more than 300 miles of the area,
the depth of about 1000 to 1500 feet below the surface.
During World War II, the ocean of human knowledge and find themselves in very
short, which set off an exploration boom. We are sailing vessels and submarines
through the oceans in the world, only the most superficial of the geographical concept,
and although predicted tides, currents and waves ability to change is the key to the
success of military operations, but the rhythm of human beings for the sea, still very
limited knowledge . Since the ocean is indeed the need to explore, the United States
and other major maritime powers began to invest effort to engage in marine scientific
research. Through the instruments and equipment (these tools are mostly due to the
urgent needs of students), marine scientists to detect seafloor topography, deep
changes in the current study, even sample collected from the sea bed.
Day after day, is like sailing in a number of albatross round the small room, the
room's walls are soft gray curtain, the floor is as smooth as glass.
Sometimes wings like a swallow flying Swallow room, and out through the wall like
magic. In the evening, before sunset sinking like a pale silver disc hanging in the
rigging of the ship, floating mist, streamer scattered, looking at the picture, we can not
help but want to recite a poem by Coleridge. We can feel a powerful force, but can not
see the power of appearance ... ...
   The book writer is 蕾切尔卡森 (Rachel L. Carson ,1907 - 1964), American
Nature Writers, a pioneer in the environmental movement, known as the mother of
ecological and environmental protection. Women graduated from the University of
Pennsylvania in 1929, 1932, a master's degree in zoology Hopkins
University, received in 1936 became employed by the U.S. Fish Authority aquatic
biologist. Published in 1951, "Marine Communication" (17he
Sea Around Us), 39 周 won "New York Times" best-selling
top. Translator is Fangshu Hui and Yu Jialing.
In 1962, she published "Silent Spring" (Silent Spring) caused
great repercussions in the community, promoted the rapid development of
environmental protection. Her writings are "under the sea
breeze"        (Under      the   Sea-Wind),       "Ocean's
Edge" (The Edge of the Sea) and so on.
