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. -

Ocean legend Valerie Taylor separates truth from tall tales. I’M OFTEN REFERRED TO as a scientist. I’m not. I write from 65 years of experience. The oceans have been very good to my husband Ron and me. They’ve given us a life of excitement and adventure. The marine world is my teacher, my workplace, and my love, yet Ron and I have but dabbled in what it offers–unknown depths and their mysterious creatures, covering 72 per cent of our planet’s surface. Ron and I learnt very early that footage of sharks would sell more readily than that of any other marine animal. In the 1950s Movietone News (an international cinema-shown newsreel covering the years 1929–79) bought Ron’s 16 mm footage, blew it up to 35 mm and showed it in theatres around the world. Then came television (in 1956 in Australia) and the public’s lust for any images of sharks had us searching offshore waters for these “dangerous” predators. For us, filming sharks in their natural environment became a way of life. Much of my first-hand knowledge was acquired in the 1980s when using the mesh suit. There’s no easy way to describe sharks. There are hundreds of species, all with different characteristics, but few of them are potentially dangerous to humans. The most threatening species cruising our coastline is the white shark. -

June 24, 2016 Mayor Libby Schaaf 1 Frank H. Ogawa Plaza 3Rd Floor
ALASKA CALIFORNIA FLORIDA MID -PACIFIC NORTHEAST NORTHERN ROCKIES NORTHWEST ROCKY MOUNTAIN WASHINGTON, D.C. INTERNATIONAL June 24, 2016 Mayor Libby Schaaf 1 Frank H. Ogawa Plaza 3rd Floor Oakland, CA 94612 Appended below are the names of 7,792 individuals who have submitted public comments opposing the proposed coal export terminal in the City of Oakland. In addition to signing on in support of the following letter, 1,911 individuals of the total number have submitted personalized comments. The personalized comments start on page 2 and end on page 113. RE: Put a stop to coal exports from Oakland Dear Mayor Libby Schaaf, CC: Governor Brown, State Senator Loni Hancock, Assemblymember Tony Thurmond, and Assemblymember Rob Bonta I strongly oppose the proposal to ship coal through the Oakland Bulk and Oversized Terminal. The mile-long coal trains bringing coal from Utah would release hundreds of pounds of toxic coal dust into the air as they travel to the proposed coal terminal, and the project developer is not bound by any enforceable commitments to protect community members from coal dust releases at the coal terminal. Communities like West Oakland already suffer from high rates of asthma, heart disease and cancer. More pollution should not be released into the neighborhoods near the proposed terminal and train lines. Allowing coal exports from Oakland undermines commitments made by the City of Oakland and the State of California to fight climate pollution. Coal-fired power plants are among the biggest emitters of climate change-forcing greenhouse gases, and allowing coal exports would allow these plants to continue operations.
