Breathing & Buoyancy Control: Stop, Breathe, Think, And
Breathing & Buoyancy control: Stop, Breathe, Think, and then Act For an introduction to this five part series see: House of Cards 'As a child I was fascinated by the way marine creatures just held their position in the water and the one creature that captivated my curiosity and inspired my direction more than any is the Nautilus. Hanging motionless in any depth of water and the inspiration for the design of the submarine with multiple air chambers within its shell to hold perfect buoyancy it is truly a grand master of the art of buoyancy. Buoyancy really is the ultimate Foundation skill in the repertoire of a diver, whether they are a beginner or an explorer. It is the base on which all other skills are laid. With good buoyancy a problem does not become an emergency it remains a problem to be solved calmly under control. The secret to mastery of buoyancy is control of breathing, which also gives many additional advantages to the skill set of a safe diver. Calming one's breathing can dissipate stress, give a sense of well being and control. Once the breathing is calmed, the heart rate will calm too and any situation can be thought through, processed and solved. Always ‘Stop, Breathe, Think and then Act.' Breath control is used in martial arts as a control of the flow of energy, in prenatal training and in child birth. At a simpler more every day level, just pausing to take several slow deep breaths can resolve physical or psychological stress in many scenarios found in daily life. -

Today, large-scale space habitation, and the opportunity to take advantage of the vast resources and possibilities of outer space, remains more in the realm of speculation than reality. We have experienced fifteen years of continuous space habitation and construction, with another seven years scheduled. Yet we have still not been able to take major steps towards commercial and industrial space development, which is usually the most-cited reason for establishing orbital colonies. This is mainly due to the prohibitively high cost, even today. In this situation, we cannot easily afford the luxury of testing how such systems could eventually work in space. This leaves us looking for analogous situations. While some scientists have sought this in the mountains of Hawaii, this does not tell the full story. We are unable to properly fathom or test how a large-scale industrial and tourism operation, as it is expected will eventually exist on-orbit, on Earth. This led us to the idea of building an oceanic base. The ocean is, in many ways, similar to free space. Large swathes of it remain unexplored. There are unrealised commercial opportunities. There are hostile yet exciting environments. Creating basic life support and pressure-containing structures are challenging. -

The “All-In-One” Vehicle Moving easily between manned and autonomous roles, STIDD’s new generation of propulsion vehicles provide operators innovative options for an increasingly complex underwater environment. Over the past 20 years, STIDD built its Submersible line and flagship product, the Diver Propulsion Device (DPD), around the basic idea that divers would prefer riding a vehicle instead of swimming. Today, STIDD focuses on another simple, but transformative goal: design, develop, and integrate the most advanced Precision Navigation, Control, Communications, and Automation Technology available into the DPD to make that ride easier, more effective, and when desired . RIDERLESS! DPD2 - Manned Mode 1 DPD2 - OM2 Mode Precision Navigation, Control, Communications & Automation System for the DPD POWERED BY RNAV2 GREENSEA Building on the legacy of its Diver Propulsion Device (DPD), the most widely used combat vehicle of its kind, STIDD designed and developed a system of DPD Navigation, Control, Communications, and Automation features which enable a seamless transition between Manned and fully Autonomous modes. RNAV2 was developed by STIDD partnering with Greensea as the backbone of this capability. RNAV2 is powered by Greensea’s patent-pending OPENSEA™ operating platform, which not only enables RNAV2’s open architecture, but also seamlessly integrates STIDD’s OM2/AP2 Diver Assist /S2 Sonar/ AC2 Communications products into an intuitive, easy to use, autonomous system. When fully configured with the Precision Navigation, Control & Automation System including RNAV2/ OM2/AP2/S2/AC2, any DPD easily transitions between Manned, DPD with RNAV2 Installed Semi-Autonomous, and Full-Autonomous modes. -
Law of Hydrostatics‘’)
10 LAW OF HYDROSTATICS‘’) 10.1 INTRODUCTION When a fluid is at rest, there is no shear stress and the pressure at any point in the fluid is the same in all directions. The pressure is also the same across any longitudinal section parallel with the Earth’s surface; it varies only in the vertical direction, that is, from height to height. This phenomenon gives rise to hydrostatics, the subject title for this chapter. Following this introduction, this chapter addresses (once again) pressure principles, buoyancy effects (including Archimedes’ Law), and manometry principles. 10.2 PRESSURE PRINCIPLES Consider a differential element of fluid of height, dz, and uniform cross-section area, S. The pressure, P, is assumed to increase with height, z. The pressure at the bottom surface of the differential fluid element is P; at the top surface, it is P + dP. Thus, the net pressure difference, dP, on the element is acting downward. A force balance on this element in the vertical direction yields: downward pressure force - upward pressure force + gravity force = 0 (10.1) Fluid Flow for the Pmcticing Chemical Engineer. By J.

The Next Generation of Ocean Exploration. Kelly Walsh Repeats Father’S Historic Dive, 60 Years Later, on Father’S Day Weekend
From father to son; the next generation of ocean exploration. Kelly Walsh repeats father’s historic dive, 60 years later, on Father’s Day weekend DSSV Pressure Drop. Challenger Deep, Mariana Trench 200miles SW of Guam. June 20th, 2020 – Kelly Walsh, 52, today completed a historic dive to approximately 10,925m in the Challenger Deep. The dive location was the Western Pool, the same area that was visited by Kelly’s father, Captain Don Walsh, USN (Ret), PhD, who was the pilot of the bathyscaph ‘Trieste’ during the first dive to the Challenger Deep in 1960. Mr. Walsh’s 12- hour dive, coordinated by EYOS Expeditions, was undertaken aboard the deep-sea vehicle Triton 36000/2 ‘Limiting Factor” piloted by the owner of the vehicle Victor Vescovo, a Dallas, Texas based businessman and explorer. The expedition to the Challenger Deep is a joint venture by Caladan Oceanic, Triton Submarines and EYOS Expeditions. Mr. Vescovo and his team made headlines last year by completing a circumnavigation of the globe that enabled Mr. Vescovo to become the first person to dive to the deepest point of each of the worlds five oceans. The dives by father and son connect a circle of exploration history that spans 60 years. “It was a hugely emotional journey for me,” said Kelly Walsh aboard DSSV Pressure Drop, the expedition’s mothership. “I have been immersed in the story of Dad’s dive since I was born-- people find it fascinating. It has taken 60 years but thanks to EYOS Expeditions and Victor Vescovo we have now taken this quantum leap forward in our ability to explore the deep ocean. -
