Estimating Your Air Consumption
10/29/2019 Alert Diver | Estimating Your Air Consumption Estimating Your Air Consumption Advanced Diving Public Safety Diving By Mike Ange Mastering Neutral Buoyancy and Trim Military Diving Technical Diving Scientific Diving and Safety Program Oversight Seeing the Reef in a New Light ADVERTISEMENT Do you have enough breathing gas to complete the next dive? Here's how to find out. It is a warm clear day, and the Atlantic Ocean is like glass. As you drop into the water for a dive on North Carolina's famous U-352 wreck, you can see that the :: captain has hooked the wreck very near the stern. It is your plan to circumnavigate the entire structure and get that perfect photograph near the exposed bow torpedo tube. You descend to slightly below 100 feet, reach the structure and take off toward the bow. Unfortunately, you are only halfway, just approaching the conning tower, when your buddy signals that he is running low on air. Putting safety first, you return with him to the ascent line — cursing the lost opportunity and vowing to find a new buddy. If you've ever experienced the disappointment of ending a dive too soon for lack of breathing gas or, worse, had to make a hurried ascent because you ran out of air, it may surprise you to learn that your predicament was entirely predictable. With a little planning and some basic calculations, you can estimate how much breathing gas you will need to complete a dive and then take steps to ensure an adequate supply. It's a process that technical divers live by and one that can also be applied to basic open-water diving. -

How Does the Diver Work? Preparing the Plastic Soda Bottle
How Does the Diver Work? Preparing the Plastic Soda Bottle Vv'hen you build a Cartesian diver, you are exploring three scientific properties of air: You will need to start collecting plastic soda bottles with caps. While (1) Air has weight almost any size bottle will work, the most popular sizes are 1 liter, 1.5 liter, and 2 liter bottles. Smaller children will find that the 1 and 1.5 liter (2) Air occupies space bottles are easiest to squeeze. The best soda bottles are those that are (3) Air exerts pressure. clear from top to bottom so that you can see everything that is happening in the bottle. Generally speaking, an object will float in a fluid if its density is less than that of the fluid (densltyemass/volume). If the object is more dense than the fluid, then the object will sink. For example, an empty bottle will float in a bathtub that is filled with water if the bottle is less dense than the water. However, as you start filling the bottle with water, its Here's an easy method for density increases and its buoyancy decreases. Eventually, the bottle will sink if it is filled too full with water. ~ cleaning the plastic The Cartesian diver, consisting of a plastic medicine dropper and soda bottles: a metal hex nut, will float or sink in the bottle of water depending on the water level in the bulb of the dropper. Vv'hen pressure is applied to the outside of the bottle, water is pushed up inside the diver, and the air • Rinse out the bottle using warm water. -

The U.S. Navy is adapting by continuing its blue-water dominance while simultaneously building brown-water ca- pabilities. Unmanned systems, such as unmanned airborne drones, are proving piv- otal in facing new battlefield challenges. Unmanned underwater vehicles (UUVs) are emerging as the Navy's seaborne equivalent of the Air Force's drones. Representing a low-end disruptive technology relative to traditional shipborne operations, UUVs are becoming capable of taking on increasingly complex roles, tipping the scales of battlefield entropy. They improve mission outcomes and operate for a fraction of the cost of traditional operations. -

The historical era of the Caribbean has seen the decline and introduction of various different and opposing cultures. Because of this, the cultural landscape of the Caribbean today is one of the most diverse in the world. However, some of these cultures have been more extensively explored archaeologically than others. A few of the areas of study that have begun to receive more attention in recent years are contact era interaction, indentured labor populations, historical environment and landscape, re-excavation of colonial sites with new discoveries and interpretations, and other aspects of daily life in the colonial Caribbean. This symposium seeks to explore new areas of overlooked peoples, cultures, and activities that have -
Annual Report 2012
The SHIPS Project - Annual Report 2012 A UK Maritime Research Project funded by ProMare 1 SHIPS Project Report 2012 ProMare President and Chief Archaeologist Dr. Ayse Atauz Phaneuf Project Manager Peter Holt Foreword The SHIPS Project has a long history of exploring Plymouth Sound, and ProMare began to support these efforts in 2010 by increasing the fieldwork activities as well as reaching research and outreach objectives. 2012 was the first year that we have concentrated our efforts in investigating promising underwater targets identified during previous geophysical surveys. We have had a very productive season as a result, and the contributions that our 2012 season’s work has made are summarized in this document. SHIPS can best be described as a community project, and the large team of divers, researchers, archaeologists, historians, finds experts, illustrators and naval architects associated with the project continue their efforts in processing the information and data that has been collected throughout the year. These local volunteers are often joined by archaeology students from the universities in Exeter, Bristol and Oxford, as well as hydrography and environmental science students at Plymouth University. Local commercial organisations, sports diving clubs and survey companies such as Swathe Services Ltd. and Sonardyne International Ltd. support the project, particularly by helping us create detailed maps of the seabed and important archaeological sites. I would like to say a big ‘thank you’ to all the people who have helped us this year, we could not do it without you. Dr. Ayse Atauz Phaneuf ProMare President and Chief Archaeologist ProMare Established in 2001 to promote marine research and exploration throughout the world, ProMare is a non-profit corporation and public charity, 501(c)(3). -
