The Sunless Sea

BACKGROUND: I was educated at the Pennsylvania College for Women and John Hopkins University. In 1932, I received a Master's degree in zoology and then continued my Marine Biology studies in Massachusetts. My first best-selling book was titled "The Sea Around Us," but my most famous book is "Silent Spring," which rose awareness of the effects of pollution and DDT on the environment, causing the banning of the chemical all together.

Rachel Carson: "The Sunless Sea"

2: THE FIRST DIVERS: "The Sunless Sea" is an essay which explores one big question: what exactly resides in the depths of the ocean? Carson navigates these mysteries through a review of the first divers who explored these deeper depths, which had previously just been an unsolved, enigmatic, vast and dark plane. The ocean extends over three-fourths of the Earth, and the first people to deep sea dive beyond its light were William Beebe and Otis Barton, reaching 3028 feet below off Bermuda in 1934. Later, the French dived over a mile deep in 1953. Deep water experiences slow change, so there is no alteration of darkness and light at that depth. It has also been found that where the reach of sunlight ends, a phenomenon of luminescence begins. There are different species that have adapted to light up the ocean for themselves.

1: EVIDENCE OF LIFE: It was long believed that nothing could live in the deep sea. However, new evidence emerged as technology improved. Worms were found in mud 1000 fathoms below, and, in 1860, a ship pulled up starfish on cable from a depth of 1260 fathoms. Within that same year, coral was also found at 1200 fathoms.

RHETORIC: I was praised for my use of scientific research in my writing. I consider my technique to be very forthright. For "The Sunless Sea," I surveyed those who had attempted to dive down in the deep. I also took care with detail, adding plenty of imagery, description, and metaphors.

CONCLUSION: Carson claims that there are mysteries of the deep that we will never discover, and that's okay. Science can't always unearth everything, and we agree with this. However, Carson doubts that there are any real "living fossils" in the depths of the ocean, but we believe that there are places science will never reach and that there may very well be many creatures which link us to our past. There is a beauty in the dark mysteries of the ocean, and, in some ways, maybe they should be left to rest, and we can simply continue to wonder about the untouchable depths of our oceans.

4: QUESTIONS:What underwater creatures do we still not know about?How do all of these different creatures live in such harsh conditions of these deep waters?Will we ever uncover all the oceans secrets?

3: HYDROPHONES: The belief that the deep ocean is silent is incredibly false. Hydrophones have picked up a plethora of noises. Fish and other marine life create a huge uproar, unperceivable to human ears. Croakers, whales, and dolphins were picked up by hydrophones during WWII, and many were hearing these sounds for the first time. But several scientists believe that there may even be the sounds of ancient creatures that have survived for centuries in the deepest parts of the ocean.
