Technical Diving
Technical diving (also referred to as tec diving or tech diving) is scuba diving that exceeds the agency-specified limits of recreational diving Recreational diving or sport diving is diving for the purpose of leisure and enjoyment, usually when using scuba equipment. The term "recreational diving" may also be used in contradistinction to "technical diving", a more demanding aspect of ... for non-Professional diver, professional purposes. Technical diving may expose the diver to hazards beyond those normally associated with recreational diving, and to a greater risk of serious injury or death. The risk may be reduced by appropriate skills, knowledge and experience, and by using suitable equipment and procedures. The skills may be developed through appropriate specialised training and experience. The equipment often involves breathing gases other than air or standard nitrox mixtures, and multiple gas sources. The popularisation of the term ''technical diving'' has been credi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Speleological Society
The National Speleological Society (NSS) is an organization formed in 1941 to advance the exploration, conservation, study, and understanding of caves in the United States. Originally headquartered in Washington D.C., its current offices are in Huntsville, Alabama. The organization engages in the research and scientific study, restoration, exploration, and protection of caves. It has more than 10,000 members in more than 250 grottos. History The Speleological Society of the District of Columbia (SSDC) was formed on May 6, 1939 by Bill Stephenson. In the fall of 1940, the officers of the SSDC drafted a proposed constitution that would transform the SSDC into the National Speleological Society. On January 24, 1941, Stephenson sent a letter to all members of the SSDC announcing that "on January 1 the Society was reorganized as a national organization." The New England Grotto was the first NSS Grotto. It was chartered in 1941 with Clay Perry as president and Ned Anderson as vice pr ...

Rebreather
A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's breathing, exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user. This differs from open-circuit breathing apparatus, where the exhaled gas is discharged directly into the environment. The purpose is to extend the breathing endurance of a limited gas supply, and, for covert military use by frogmen or observation of underwater life, eliminating the bubbles produced by an open circuit system and in turn not scaring wildlife being filmed. A rebreather is generally understood to be a portable unit carried by the user. The same technology on a vehicle or non-mobile installation is more likely to be referred to as a life-support system. Rebreather technology may be used where breathing gas supply is limited, such as underwater or in space, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chief Executive Officer
A chief executive officer (CEO), also known as a central executive officer (CEO), chief administrator officer (CAO) or just chief executive (CE), is one of a number of corporate executives charged with the management of an organization especially an independent legal entity such as a company or nonprofit institution. CEOs find roles in a range of organizations, including public and private corporations, non-profit organizations and even some government organizations (notably state-owned enterprises). The CEO of a corporation or company typically reports to the board of directors and is charged with maximizing the value of the business, which may include maximizing the share price, market share, revenues or another element. In the non-profit and government sector, CEOs typically aim at achieving outcomes related to the organization's mission, usually provided by legislation. CEOs are also frequently assigned the role of main manager of the organization and the highest-ranking offic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High Springs, Florida
High Springs is a city in Alachua County, Florida, United States. It is the fourth-largest city in Alachua County and seventh-largest in North Central Florida. The population was 6,215 at the 2020 census. History The present-day area of High Springs was first settled on a permanent basis by English-speaking people during the late 1830s. One of the earliest settlements in the vicinity was at Crockett Springs, located about three miles east of present-day High Springs. Settlers who were living there during the 1840s included Fernando Underwood and Marshal Blanton. A discernible town began to develop in the early 1880s after the Savannah, Florida & Western Railway was constructed and several phosphate mines were established. A railroad station and a post office called Santaffey were established in 1884. The post office was renamed Santa Fe a few months later, then Orion the next year, and in 1888 it became High Springs, and the town was officially incorporated in 1892. The town had ...

Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...

Woodville Karst Plain Project
The Woodville Karst Plain Project or WKPP, is a project and organization that maps the underwater cave systems underlying the Woodville Karst Plain. This plain is a area that runs from Tallahassee, Florida, U.S. to the Gulf of Mexico and includes numerous first magnitude springs, including Wakulla Springs, and the Leon Sinks Cave System, the longest underwater cave in the United States. The project grew out of a cave diving research and exploration group established in 1985 and incorporated in 1990 (by Bill Gavin and Bill Main, later joined by Parker Turner, Lamar English and Bill McFaden, at the time the chairman of the NACD Exploration and Survey Committee). WKPP is the only organization currently allowed to dive some of these caves – which are all on State, Federal, or private land – due to the extreme nature of the systems and the discipline required to safely explore them, although these caves were explored extensively prior to the establishment of the WKPP. This is a con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advisory Board
An advisory board is a body that provides non-binding strategic advice to the management of a corporation, organization, or foundation. The informal nature of an advisory board gives greater flexibility in structure and management compared to the board of directors. Unlike the board of directors, the advisory board does not have authority to vote on corporate matters or bear legal fiduciary responsibilities. Many new or small businesses choose to have advisory boards in order to benefit from the knowledge of others, without the expense or formality of the board of directors. Function The function of an advisory board is to offer assistance to enterprises with anything from marketing to managing human resources to influencing the direction of regulators. Advisory boards are composed of accomplished experts offering innovative advice and dynamic perspectives. Meeting quarterly or biannually, boards can provide strategic direction, guide quality improvement, and assess program effec ...

Board Of Directors
A board of directors (commonly referred simply as the board) is an executive committee that jointly supervises the activities of an organization, which can be either a for-profit or a nonprofit organization such as a business, nonprofit organization, or a government agency. The powers, duties, and responsibilities of a board of directors are determined by government regulations (including the jurisdiction's corporate law) and the organization's own constitution and by-laws. These authorities may specify the number of members of the board, how they are to be chosen, and how often they are to meet. In an organization with voting members, the board is accountable to, and may be subordinate to, the organization's full membership, which usually elect the members of the board. In a stock corporation, non-executive directors are elected by the shareholders, and the board has ultimate responsibility for the management of the corporation. In nations with codetermination (such as Germ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Fe River (Florida)
The Santa Fe River is a river in northern Florida.

The headwaters of the river are Lake Santa Fe, near Keystone Heights, Florida, Keystone Heights. The Santa Fe River is usually a slow-flowing river. This slow speed, combined with the abundant leaf-drop from nearby trees, especially Taxodium distichum, Bald Cypress, leads to a very Blackwater river, dark-brown river due to dissolved tannins. The Santa Fe River is typical of many rivers in karst regions in that it completely disappears underground and then reappears downstream. The river drops into a large sinkhole in O'Leno State Park and reappe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
