Of all the 19th century oceanographic expeditions, the best known is the five-year voyage of the HMS Beagle. Departing from Plymouth, England on December 27, 1831, the Beagle sailed under the command of Robert Fitzroy. With the now-famous Charles Darwin aboard as the ship’s naturalist among a crew of 73, the Beagle ultimately circled the Earth, voyaging along both coasts of South America while studying the southern oceans. The route along South America proved especially interesting to Darwin. Much of his time was spent studying the geology and biology of the coastline.
Darwin was particularly interested in the Galapagos Islands in Ecuador. Darwin carefully noted the changes in organism characteristics and habitats in correspondence with their latitude. As the Beagle sailed through the warm South Pacific, Darwin turned his attention to coral and coral reefs. Among his many observations, he noted that coral only grows in relatively shallow, warm water. however, extended far deeper than coral grows. Darwin hypothesized that the massive coral reefs could only result from the sea floor slowly sinking. He went on to propose that as the sea floor descends, coral grows upward to remain in the shallow water it needs to survive. This hypothesis became the basis for Darwin’s first major published work, Structure and Distribution of Coral Reefs. Darwin’s explanation that coral reefs form by growing upward as the sea floor recedes is the explanation accepted by scientists today.When you hear an owl at night meaning?
