From the depths of Lake Baikal to the Ocean Floor. Illustrated.
Admiring the changing colours of the ocean, listening to its surging tide, and gazing at its zigzaggy skyline, you hardly even suspect that its dark and mysterious floor is the scene where continuous changes of global significance take place.
Only recently, nobody had the slightest idea of such processes. But now marine geologists study many of them to reveal more about the geological history of the earth. Research involving scores of instruments and devices allowed to obtain evidence about processes deep inside the ocean, and submerisions on board of bathysaphes have enabled researchers to conduct deep-sea exploration.
The authors of this book, deep-sea explorers themselves, speak of the ocean floor as if there were no water around all the great fissures and underwater volcanoes. They see basalt lavas along with solutions of even higher temperature than molten lead.
Over boundless plains covered with thick silt, they come across long ridges and even eruptions of hot black smoke. The most important thing is that the authors not only describe many interesting and mysterious phenomena but also try to explain them.
The book gives the reader a chance to learn more about the geological history of our planet. So let us probe the sombre ocean depths to witness all the obsure but exciting developments, only recently a complete enigma.
