Many people believe that simply having their life jacket on the boat or water vessel they are using is enough. Ro Woodard, Education Specialist for the NYS Parks and Marine Services Bureau said, “the wear rate for life jackets is low among adults that don’t have to wear them.” The Wear It!
The most important thing to remember when wearing a life jacket is “To have it properly secured, the proper fit, and nothing is a guarantee. Respect your surroundings,” said Jeff McCrobie, chief of the Oswego City Fire Department.

NASA researchers who developed a new way to power robotic underwater vehicles believe a spin-off technology could help convert ocean energy into electrical energy on a much larger scale. Other technologies have been designed -- and are being developed -- to turn the energy of ocean currents, tides, and flowing rivers into another kind of power, called hydrokinetic energy. Jack Jones, an engineer at NASA's Jet Propulsion Laboratory, and Yi Chao, a JPL scientist, have designed a new kind of underwater hydrokinetic energy system. In this project, initiated by Pat Beauchamp of JPL's Center for In Situ Exploration and Sample Return, Jones was asked to develop a way to use temperature differences in the ocean to power submersibles. In the the energy transfer system Jones and Chao propose, ocean tides and waves, as well as river flows, would provide the energy source to create a high-pressure liquid. Jones and Chao designed a system that takes advantages of changes in ocean temperature to create a high-pressure fluid that can be used to generate power. While they were working on this project, the researchers realized that they could employ the same concept -- using an environmental pump to generate a high-pressure liquid -- to produce electricity from the world's ocean.

The HK91 is a semi-automatic, civillian-legal co-variant rifle designed off the most recognized combat rifle of the 20th & 21st century, the HKG3A1. Madagascar is thought to be the worlda€™s oldest island and is home to over 8,000 endemic species. The isolated nature of islands results in them being home to a wide diversity of plant and animal species that can be found nowhere else on Earth, making islands attractive destinations for both biologists and tourists alike. Islands and their surrounding waters account for around a sixth of the worlda€™s total area, but for their size they are home to a surprisingly high proportion of the worlda€™s animals and plants. Some of these species are descended from mainland ancestors, after the land they inhabited drifted away from the main continent as the Eartha€™s tectonic plates moved, while others colonised newly formed land which had emerged from the sea bed. Remote islands often provide important habitats for migratory species, some of which, such as the Chatham albatross, may only breed on a single island.
Island species are also vulnerable to the introduction of invasive species, as they have typically evolved in isolation with limited competition. The other main risks to island species are natural disasters, habitat destruction, tourism development, overexploitation and pollution. Although once widespread throughout Southeast Asia, today the Bornean orangutan is restricted to the island of Borneo. The Juan FernA?ndez petrel faces its greatest threats on its tiny breeding island, where numerous introduced species are causing extensive damage to the natural ecosystem. The Lord Howe Island stick-insect was believed Extinct due to predation by introduced black rats until it was rediscovered surviving on a single island outcrop known as Balla€™s Pyramid.
Although the small size of many islands can be a risk factor for island species, it can also prove beneficial to conservation projects that would not be feasible in larger areas. For example, small, predator-free islands are providing a safe haven for the kakapo, a large flightless parrot from New Zealand. The Antiguan racer is a species of snake once believed to be Extinct, before being rediscovered in 1989 on Great Bird Island, Antigua. The pink pigeon, from the island of Mauritius, has been rescued from the brink of extinction by an intensive management programme.
These conservation projects are ongoing and need to be sustained, but are great examples of what concerted conservation efforts can achieve on islands.

Islands have been profiled with support from The Bromley Trust to help raise awareness about the importance of islands and their distinctive biodiversity, and the need for their protection and conservation. To make sure that your life jacket fits properly McCrobie said “Check the tag or the inside of the life jacket to see if it contains weight guidelines. The rotor's rotational speed is increased through a gearbox, which drives a high-pressure fluid pump. The researchers hope that clean, renewable energy produced from the motion of the ocean and rivers could potentially meet an important part of the world's demand for electricity.
Hydroelectric plants, for example, are among the most established and least expensive sources of electricity. Many of these hydrokinetic energy systems use underwater turbines, similar to those in wind farms.
Most robotic underwater vehicles run on batteries and have to be recovered by ship to have their batteries recharged or replaced.
As the water turns underwater turbine blades, the rotor's rotational speed would be increased through a gearbox, which drives a high-pressure fluid pump. Scientists can use state-of-the-art computer models of winds, river flows, ocean currents and tides to determine any location's potential for energy production, he adds.
There are two main types of island: continental islands such as Borneo and Barbados, which lie on a continental shelf, and oceanic islands such as Hawaii and Tonga, which are usually formed by volcanoes.
Estimates suggest that 20 percent of all species of birds, reptiles and plants are found on islands.
Over time these isolated species developed adaptations to suit their habitat, distinguishing them from their mainland counterparts, and they ultimately evolved into separate species. Island species are often only present in relatively small numbers, putting them at greater risk, and the limited habitat available to them means they cannot easily disperse elsewhere. These pressures show their impacts on islands before they would be visible on larger land masses. The kakapo was once widespread throughout New Zealand but its population was decimated by hunters, introduced predators and forest clearing. The Antiguan Racer Conservation Project eradicated rats and mongooses from Great Bird Island and 11 other offshore islands. A captive breeding and release programme, supplemented by efforts such as the establishment of Conservation Management Areas, habitat restoration, control of predators and supplementary feeding, has enabled this species to increase in abundance.

Inflatable life preservers are lightweight and cooler and can be pulled off and over your head in the case of an emergency. For instance, if you are boating by yourself or boating when the weather takes a turn for the worse.
They are encouraging boaters to sign the pledge to wear a life jacket whenever they are out on the water. Those who sign the pledge will receive a free whistle for their life jacket.


The high-pressure fluid would be transported though flexible tubes to a larger pipe and then to an efficient, onshore hydroelectric power plant.
They benefit from the large hydrostatic pressure difference between the water surface behind the dam and the turbines that can be harnessed to produce power. Ocean currents or tides turn the turbines, which generate electricity that can be transferred by cable to shore. Similar issues exist with two other types of hydrokinetic systems in use in the United Kingdom and planned for South Korea. They can also predict how much energy could be produced in the future to help in planning energy use and storage.

In addition to this, what makes islands special is that many of the animals and plants found there are endemic, meaning they are found nowhere else on Earth. Over half of the worlda€™s marine biodiversity is found in the waters surrounding islands, including some of the worlda€™s most spectacular coral reefs.
This also means that island species are particularly vulnerable to the effects of climate change, such as rising temperature and sea levels, extreme weather events, and fires. As humans have travelled the world they have introduced large numbers of non-native species to islands, sometimes with devastating consequences, and on some islands the alien species now outnumber the native ones. In the past 20 years, 80 percent of this speciesa€™ habitat has been lost to illegal logging, gold mining and conversion to permanent agriculture such as oil palm plantations. In 1989, the Kakapo Recovery Plan was developed and all the surviving individuals were relocated to suitable predator-free islands where they could breed.
After captive breeding and reintroductions to the now predator-free islands, the population increased to around 300 individuals by 2009.
Low resolution, watermarked versions of the Material may be copied from this website by such End Users for such purposes. These life preservers have a carbon dioxide cartridge inside and are inflated either manually or automatically (which is recommended). But the power that can be produced in this manner is limited, because most of the suitable rivers already have hydroelectric dams.
Caltech, which operates JPL for NASA, holds the patent on this innovative energy technology.
For example, over 90 percent of the species found in Hawaii are endemic, and Madagascar alone has over 8,000 endemic species. Prior to relocation, the islands underwent extensive re-vegetation, and introduced mammalian predators and competitors were eradicated. If you require high resolution or non-watermarked versions of the Material, please contact Wildscreen with details of your proposed use. The thing is you never know if there will be circumstances where you need a life jacket and with the different options that are now available, there are life preservers that will work for your purposes and preferences. It should.” It is also important to remember that when choosing a life that they should be US Coast Guard Approved. All children under the age of 12 are required to wear a life preserver and they are required for everyone being towed by a boat, jet ski, etc.
The project is intensive and ongoing, but kakapo numbers have increased from 51 individuals in 1995 to 126 individuals in 2013. They are spreading the word that you can keep yourself safe this summer while you are out having fun on the water.
