Promoting the region’s natural assets can help build vibrant communities and support local economies. This series of fact sheets profiles different outdoor recreation activities that could appeal to residents and visitors of Michigan’s Thumb. We hope this information will help guide regional planning, business develop- ment and marketing efforts throughout the region. Here we focus on scuba diving – providing details on what is involved in the sport, who participates, and what is unique about diving in Lake Huron. WHY DIVE IN LAKE HURON? With wildlife, shipwrecks, clear water and nearshore dives, the waters of southern Lake Huron create a unique environment for scuba divers. Underwater life abounds, including colorful sunfish and unusual species like the longnose gar. The area offers a large collection of shipwrecks, and is home to two of Michigan’s 12 underwater preserves. Many of the wrecks are in close proximity to each other and are easily accessed by charter or private boat. The fresh water of Lake Huron helps to preserve the wrecks better than saltwater, and the lake’s clear water offers excellent visibility – often up to 50 feet! With many shipwrecks at different depths, the area offers dives for recreational as well as technical divers. How Popular is Scuba Diving?

  • 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.

In my line of work as a dive industry professional, I attend a lot of dive shows and get to meet a lot of people, most of them nice and interesting in various ways. It was also at a dive show in Italy, many years ago, that I first met Andrea Donati and his partner, Daniela Spaziani, of Ponza Diving. I clearly remember my first impression of how sympathetic, unpretentious and genuine the two came across, which scores a lot of points in my book. They appeared competent and organised, and with their operation located in one of the most picturesque locations I have ever seen, it did not take any arm twisting to lure me down there for a visit.

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.

  • Stepping Into Rebreather Rebreather Diving
    SSteptepping into rebreather diving By Paul Beenaround Alex had always been interested in learning to dive with the new breed of closed circuit rebreather’s that had appeared in recent years, so when he was suddenly faced with the choice of a dance weekend in chilly Munich or a week learning to dive with them in the Red Sea it wasn’t a hard decision to make. He was soon on his way with Easyjet flying over the Swiss Alps en-route for Sharm el sheik. Everything went very smoothly and he had soon settled down in the Camel hotel, a slightly upmarket one in the centre of Sharm which was not far from the Red Sea College where he would be doing his rebreather course. The next day he met Sherif, an impish Egyptian who was going to be his mentor for the combined basic and advanced four day course. After some classroom work he was shown the intricate workings of the Poseidon MK6 rebreather, the only one recognised by PADI for recreational sports divers on their recently introduced rebreather course. It was a very complex piece of kit, largely controlled by computer software, which took away the risk of diver error. This is unlike many other versions on the market that had caused accidents and deaths, usually through the diver making a mistake. As nice as it was to know that it was keeping him alive, the Poseidon rebreather’s had had many software problems that largely prevented you either starting a dive or necessitated aborting a dive halfway through for often non-existent faults.

PO BOX 6870 SANTA BARBARA, CA 93160 (800) 235-5741 / (805) 562-9120 WWW.CMCRESCUE.COM NFPA 1983 - HARDWARE PERFORMANCE REQUIREMENTS What is “3σ MBS?” You might think that answering the question, “How strong is that carabiner (or other item of rescue equipment)?” would be relatively easy. Yet, even with modern, high-tech alloys, two identical carabiners will break at slightly different forces. So a randomly selected sample from a population will perform within some range of break strengths. But to determine how wide that range is and, more importantly, what the lowest strength is, you would have to break every unit in the population. This would be an expensive project, and you’d end up with no useable units! The scientific solution is to use a statistical formula, referred to as three sigma (3σ). Sigma is the Greek letter used to denote standard deviation, a measure of how far a set of numbers (in this case, breaking strengths) is spread out around the mean. To determine a product’s minimum breaking strength (MBS), a sample size is chosen and tested and the results analyzed. The MBS for the entire population is then calculated by subtracting three times the standard deviation (3σ) from the mean result of the tested samples. This provides an MBS that is very near the true lower limit of the population. The larger the sample size, the higher the level of confidence that any individual from the population will meet or exceed the calculated MBS. For testing rescue equipment the NFPA has selected a sample size of five.
