Everglades National Park
Everglades National Park is a U.S. National Park in Florida that protects the southern 20 percent of the original Everglades. In the United States, it is the largest tropical wilderness, the largest wilderness of any kind east of the Mississippi River, and is visited on average by one million people each year. It is the third-largest national park in the lower 48 states after Death Valley and Yellowstone. It has been declared an International Biosphere Reserve, a World Heritage Site, and a Wetland of International Importance, one of only three locations in the world to appear on all three lists.
Bull shark
The bull shark ("Carcharhinus leucas"), also known as the Zambezi shark (informally "zambi") in Africa, and Lake Nicaragua shark in Nicaragua, is a requiem shark commonly found worldwide in warm, shallow waters along coasts and in rivers. The bull shark is known for its aggressive nature, predilection for warm shallow water, and presence in brackish and freshwater systems including estuaries and rivers. Bull sharks can thrive in both salt and fresh water and can travel far up rivers. They have been known to travel up the Mississippi River as far as Alton, Illinois, about 700 miles (1100 km) from the ocean.
Joseph Fralinger
Joseph F. Fralinger (October 22, 1848 in Sweetwater, New Jersey – May 13, 1927 in Atlantic City, New Jersey) was an American businessman and confectioner, known for being the most successful merchandiser of Salt Water Taffy. The confectionary store he founded in the late 19th century in Atlantic City, New Jersey remains a fixture on its famous boardwalk. Fralinger was a glassblower and fish merchant before he opened a retail store on the Atlantic City Boardwalk to sell his taffy. Within a year, Fralinger had added a taffy concession and spent the winter perfecting the Salt Water Taffy formula, first using molasses, then chocolate and vanilla, eventually creating 25 flavors.
Desalination
Desalination is a process that extracts mineral components from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture. Saltwater is desalinated to produce water suitable for human consumption or irrigation. One by-product of desalination is salt. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few rainfall-independent water sources.
Great Salt Lake
The Great Salt Lake, located in the northern part of the U.S. state of Utah, is the largest salt water lake in the Western Hemisphere, and the eighth-largest terminal lake in the world. In an average year the lake covers an area of around , but the lake's size fluctuates substantially due to its shallowness. For instance, in 1963 it reached its lowest recorded size at 950 square miles (2,460 km²), but in 1988 the surface area was at the historic high of . In terms of surface area, it is the largest lake in the United States that is not part of the Great Lakes region. The lake is the largest remnant of Lake Bonneville, a prehistoric pluvial lake that once covered much of western Utah.
Osmotic power
Osmotic power, salinity gradient power or blue energy is the energy available from the difference in the salt concentration between seawater and river water. Two practical methods for this are reverse electrodialysis (RED) and pressure retarded osmosis (PRO). Both processes rely on osmosis with membranes. The key waste product is brackish water. This byproduct is the result of natural forces that are being harnessed: the flow of fresh water into seas that are made up of salt water. In 1954, Pattle suggested that there was an untapped source of power when a river mixes with the sea, in terms of the lost osmotic pressure, however it was not until the mid ‘70s where a practical method of exploiting it using selectively permeable membranes by Loeb was outlined.
Salt water chlorination
Salt water chlorination is a process that uses dissolved salt (2,500–6,000 ppm) as a store for the chlorination system. The chlorine generator (also known as salt cell, salt generator, salt chlorinator or SWG) uses electrolysis in the presence of dissolved salt (NaCl) to produce hypochlorous acid (HClO) and sodium hypochlorite (NaClO), which are the sanitizing agents already commonly used in swimming pools. As such, a saltwater pool is not actually chlorine-free; it simply utilizes added salt and a chlorine generator instead of direct addition of chlorine. The presence of chlorine in traditional swimming pools can be described as a combination of free available chlorine (FAC) and combined available chlorine (CAC).

I love to swim too! I usually do in a pool, but will be swimming in the ocean this weekend, Florida bound!

That sounds exciting! How long can you hold your breath underwater?
Humans can hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as an evolutionary response.

Underwater diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water.
Physiology of underwater diving
Physiology of underwater diving is the physiological influences of the underwater environment on the physiology of air-breathing animals, and the adaptations to operating underwater, both during breath-hold dives and while breathing at ambient pressure from a suitable breathing gas supply. It, therefore, includes both the physiology of breath-hold diving in humans and other air-breathing animals, and the range of physiological effects generally limited to human ambient pressure divers either freediving or using underwater breathing apparatus. Several factors influence the diver, including immersion, exposure to the water, the limitations of breath-hold endurance, variations in ambient pressure, the effects of breathing gases at raised ambient pressure, effects caused by the use of breathing apparatus, and sensory impairment.
Scuba skills
Scuba skills are the skills required to dive safely using self-contained underwater breathing apparatus, (scuba). Most of these skills are relevant to both open circuit and rebreather scuba, and many are also relevant to surface-supplied diving. Those skills which are critical to the safety of the diver may require more practice than is usually provided during training to achieve reliable long-term proficiency  Some of the skills are generally accepted by recreational diver certification agencies as necessary for any scuba diver to be considered competent to dive without direct supervision, and others are more advanced, though some diver certification and accreditation organizations may consider some of these to also be essential for minimum acceptable entry level competence.
Swimming
Swimming is the self-propulsion of a person through fresh or salt water, usually for recreation, sport, exercise, or survival. Locomotion is achieved through coordinated movement of the limbs, the body, or both. Humans can hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as an evolutionary response. Swimming is consistently among top public recreational activities, and in some countries, swimming lessons are a compulsory part of the educational curriculum. As a formalized sport, swimming features in a range of local, national, and international competitions, including every modern summer Olympics.
Dyesebel
Dyesebel () is a popular mermaid character in the Philippines. The comic book character was originally conceived by the Filipino comic book illustrator, Mars Ravelo and drawn by Elpidio Torres. "Dyesebel" is a prominent character in Philippine cinema and television. It was first serialized in Pilipino Komiks in 1952-53, and was later adapted into the big screen that same year. The film was produced under Manuel Vistan Productions, Inc. and released through Premiere Productions. It was directed by Gerardo 'Gerry' De Leon. Dyesebel first appeared in the pages of Pilipino Komiks during the 1950s, then in Kampeon Komiks (Champion Comics) in 1975.
Apnea
Apnea or apnoea is suspension of breathing. During apnea, there is no movement of the muscles of inhalation, and the volume of the lungs initially remains unchanged. Depending on how blocked the airways are (patency), there may or may not be a flow of gas between the lungs and the environment; gas exchange within the lungs and cellular respiration is not affected. Voluntarily doing this is called holding one's breath. Apnea can be involuntarily achieved, drug-induced (such as opiate toxicity or tryptamine toxicity), mechanically induced (for example, by strangulation or choking), or it can occur as a consequence of neurological disease or trauma.
Freediving
Freediving, free-diving, free diving, breath-hold diving, or skin diving is a form of underwater diving that relies on divers' ability to hold their breath until resurfacing rather than on the use of a breathing apparatus such as scuba gear. Besides the limits of breath-hold, immersion in water and exposure to high ambient pressure also have physiological effects that limit the depths and duration possible in freediving. Examples of freediving activities are: traditional fishing techniques, competitive and non-competitive freediving, competitive and non-competitive spearfishing and freediving photography, synchronized swimming, underwater football, underwater rugby, underwater hockey, underwater target shooting and snorkeling.
