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. -

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. -

Bathyscaphe Trieste by Dennis Bryant
Royal Belgian Institute of Marine Engineers Bathyscaphe Trieste by Dennis Bryant A revolutionary diving craft, leading the way for future generations. The first ultra‐deep diving manned vessel was conceived, designed, and constructed by August Piccard, a Swiss physicist in 1947. He called the craft a bathyscaph, coined by combining the Greek words bathos, meaning deep, and scaphos, meaning ship. In 1952, he began construction of a more advanced version. Because it was built largely in the city of Trieste, he named it TRIESTE when it was launched on August 1, 1953. It consisted of a small pressure sphere about seven feet in diameter attached to the underside of roughly rectangular float chamber that was 59 feet long and eleven feet wide. The whole thing looked distinctly unseaworthy. That is because the craft was never designed to transit on the surface of the water. Rather, its sole purpose was dive deep and return to the surface. The float chamber was filled with 22,000 gallons of gasoline. This flammable liquid was selected for two reasons: first, it was lighter than water; and second, it was nearly incompressible, even at extreme pressure. The float chamber also was fitted with two ballast silos filled with 18,000 pounds of magnetic iron pellets. These pellets were to be released when the two‐ man crew wanted to ascend to the surface. Having no means of propulsion when on the surface, the Trieste had to be brought to a point almost directly above its target and then allowed to descend. The craft made various dives in the Mediterranean before it was purchased by the US Navy in 1958 for the sum or $250,000. -
ECOS Green Report Focuses on State Environmental Agency Use of UAS,1 Actual and Potential Benefits, and Current and Planned Uses by the Spotlighted State Agencies
February 2021 GREEN REPORT State Environmental Agency Modernization — Leveraging Unmanned Aerial Systems to Improve Environmental Results By Paulina Lopez-Santos, Project Associate, under the direction of Beth Graves, Executive Project Manager, Environmental Council of the States (ECOS) Copyright ©2021 by the Environmental Council of the States INTRODUCTION Unmanned aerial systems (UAS) have emerged as an important tool for state environmental agencies to quickly obtain data, more effectively respond to emergencies, and ensure worker safety while improving environmental results. UAS encompasses unmanned aerial vehicles (UAVs) (without a human pilot on board), commonly referred to as drones, as well as the person controlling the flight on the ground and a system of communications between the two. State environmental agencies have long been drivers of innovative approaches and programs to maximize environmental protection. ECOS has highlighted many examples through its annual State Program Innovation Awards, including modernized document management systems, new ways to interface with communities and share data, self-auditing programs, and more effective inspection and permitting programs. Use of UAS contributes to the continued evolution of state environmental agency approaches. This ECOS Green Report focuses on state environmental agency use of UAS,1 actual and potential benefits, and current and planned uses by the spotlighted state agencies. Each identified state environmental agency drone program is highlighted in more detail in the latter part of this report, including a summary of each state program along with benefits, current and planned activities, application highlights, lessons learned, state contacts, and links and resources. 1 In this report, the term “drone,” UAS, and UAV are used interchangeably or depending upon state preference. -
