SCIENTIFIC AMERICAN FRONTIERS PROGRAM #1503 "Going Deep" AIRDATE: February 2, 2005 ALAN ALDA Hello and welcome to Scientific American Frontiers. I'm Alan Alda. It's said that the oceans, which cover more than two thirds of the earth's surface, are less familiar to us than the surface of the moon. If you consider the volume of the oceans, it's actually more than ninety percent of the habitable part of the earth that we don't know too much about. The main reason for our relative ignorance is simply that the deep ocean is an absolutely forbidding environment. It's pitch dark, extremely cold and with pressures that are like having a 3,000-foot column of lead pressing down on every square inch -- which does sound pretty uncomfortable. In this program we're going to see how people finally made it to the ocean floor, and we'll find out about the scientific revolutions they brought back with them. We're going to go diving in the Alvin, the little submarine that did so much of the work. And we're going to glimpse the future, as Alvin's successor takes shape in a small seaside town on Cape Cod. That's coming up in tonight's episode, Going Deep. INTO THE DEEP ALAN ALDA (NARRATION) Woods Hole, Massachusetts. It's one of the picturesque seaside towns that draw the tourists to Cape Cod each year. But few seaside towns have what Woods Hole has. For 70 years it's been home to the Woods Hole Oceanographic Institution — an organization that does nothing but study the world's oceans. -

Scuba Diving History
Scuba diving history Scuba history from a diving bell developed by Guglielmo de Loreno in 1535 up to John Bennett’s dive in the Philippines to amazing 308 meter in 2001 and much more… Humans have been diving since man was required to collect food from the sea. The need for air and protection under water was obvious. Let us find out how mankind conquered the sea in the quest to discover the beauty of the under water world. 1535 – A diving bell was developed by Guglielmo de Loreno. 1650 – Guericke developed the first air pump. 1667 – Robert Boyle observes the decompression sickness or “the bends”. After decompression of a snake he noticed gas bubbles in the eyes of a snake. 1691 – Another diving bell a weighted barrels, connected with an air pipe to the surface, was patented by Edmund Halley. 1715 – John Lethbridge built an underwater cylinder that was supplied via an air pipe from the surface with compressed air. To prevent the water from entering the cylinder, greased leather connections were integrated at the cylinder for the operators arms. 1776 – The first submarine was used for a military attack. 1826 – Charles Anthony and John Deane patented a helmet for fire fighters. This helmet was used for diving too. This first version was not fitted to the diving suit. The helmet was attached to the body of the diver with straps and air was supplied from the surfa 1837 – Augustus Siebe sealed the diving helmet of the Deane brothers’ to a watertight diving suit and became the standard for many dive expeditions. -
The Weed That Feeds the North Atlantic
DRIFTING PLANTS KNOWN AS SARGASSUM SUPPORT A COMPLEX AND AMAZING VARIETY OF MARINE LIFE. The Weed That Feeds the North Atlantic BY JAMES PROSEK PHOTOGRAPHS BY DAVID DOUBILET AND DAVID LIITTSCHWAGER 129 Hatchling sea turtles, like this juvenile log- gerhead, make their way from the sandy beaches where they were born toward mats of sargassum weed, finding food and refuge from predators during their first years of life. PREVIOUS PHOTO A clump of sargassum weed the size of a soccer ball drifts near Bermuda in the slow swirl of the Sargasso Sea, part of the North Atlantic gyre. A weed mass this small may shelter thousands of organisms, from larval fish to seahorses. DAVID DOUBILET (BOTH) 130 NATIONAL GEOGRAPHIC THE WEED THAT FEEDS THE NORTH ATLANTIC 131 ‘There’s nothing like it in any other ocean,’ says marine biologist Brian Lapointe. ‘There’s nowhere else on our blue planet that supports such diversity in the middle of the ocean—and it’s because of the weed.’ LAPOINTE IS TALKING about a floating seaweed known as sargassum in a region of the Atlantic called the Sargasso Sea. The boundaries of this sea are vague, defined not by landmasses but by five major currents that swirl in a clockwise embrace around Bermuda. Far from any main- land, its waters are nutrient poor and therefore exceptionally clear and stunningly blue. The Sargasso Sea, part of the vast whirlpool known as the North Atlantic gyre, often has been described as an oceanic desert—and it would appear to be, if it weren’t for the floating mats of sargassum. -

Side Scanning Sonar - a Theoretical Study
SIDE SCANNING SONAR - A THEORETICAL STUDY by Olivier L e e n h a r d t , Institut für Geophysik der Universitàt, Kiel ABSTRACT The principle of operation in side scanning sonars is here studied. After briefly describing the various existing equipments, the influence of different design factors on the range is first examined, and then the resolution in both the horizontal and the vertical plane. Next distortions are analysed. Firstly there are those inherent in the principle adopted for tïîèuistruinent : these distortions are due either to the obliquity of the acoustic waves, or to the ratio between recording scales, or again to the slope of the sea bottom. Secondly, accidental distortions are discussed : these result from the pitch, roll or yawing of the fish carrying the transducer, from the crabwise motions of the vessel due to cross winds or currents, and from variations in the velocity of sound in water. Finally acoustic interferences are discussed : those attributable to the recording paper, to several instruments being operated simultaneously, or to shoals of fish, the Deep Scattering Layer, or to airbubbles in the water. Some indications as to how to achieve satisfactory results with a side scanning sonar for specified purposes are given in a brief conclusion. For illustrated examples the reader is referred to various earlier issues of the International Hydrographic Review. GENERAL It was to geologists in Great Britain towards the end of the 1950s that the idea of applying side scan soilar methods first came — and it is the British who have contributed the most to the development of this equipment.
