THE OCEANS MAKE UP greater than two-thirds of the Earth's floor. yet they're as mysterious for what they disguise as they're prevalent for his or her ubiquity. Deep less than the mild swell of the waves lies an alien international that even at the present time now we have in simple terms began to discover. the search to grasp extra approximately this mystery area all started in earnest in 1872 whilst HMS Challenger set sail from Portsmouth, England, to map and pattern the sea flooring. crusing 3 and part years and 69,000 nautical miles, the tale of the Challenger is the stuff of legend. Scientists and workforce alike braved the stifling warmth of the tropics for months on finish in simple terms to endure the stupefying chilly of the Antarctic, enduring probability at the excessive seas, and risking their very lives within the pursuit of data. because the first sea voyage dedicated completely to technological know-how, the Challenger excursion might be the best oceanographic project of all time, surpassing even Charles Darwin's celebrated passage aboard the Beagle. certainly, one of the extra vital pursuits set sooner than the workforce of Challenger was once the mandate to collect the facts essential to end up or refute Darwin's bold new conception of evolution. positioned easily, many observed the Challenger excursion because the final conflict among God and technology. The project used to be not anything in need of a roaring good fortune. Challenger dredged up enormous quantities of samples from the seafloor and mapped huge, immense components of undersea terrain. such a lot startling of all, even though, used to be the revelation that the sea was once even more than a barren graveyard that mutely mirrored Earth's past--it used to be no longer a silent panorama finally. in its place, they discovered a gloriously advanced atmosphere teeming with lifestyles, an ecological and geological treasure trove shall we scarcely think from our landlocked viewpoint. hoping on reputable documentation and the logs and journals of the ship's clinical employees, her officials, and workforce, The Silent panorama recounts the tale of a unprecedented voyage. yet neither technology nor the seas stay static over the years -- and this ebook is greater than a vibrant ancient yarn. within the a hundred twenty five years because the Challenger explored the good oceans of the realm, we have now realized even more in regards to the hidden mysteries of the deep. So the writer, an earth scientist and marine geologist, additionally brings a twenty first century standpoint to undergo on Challenger's learn and discoveries, illuminating the technological know-how of that nineteenth century voyage with the most up-tp-date oceanographic details to be had to us. As Challenger sails from the endangered coral reefs of the Caribbean to the trackless depths underneath the western Pacific, The Silent panorama takes us on an epic trip throughout time
