Ocean Tides

#Flood tide is an incoming tide. It is incomiong between low and high tides.

It is called a 'Flood tide' , because it floods over the tidal range.

Riptides, also known as rip currents, are strong, narrow currents that flow from the shore back to the open ocean. They can pull swimmers out to sea and are dangerous for those caught in them. It is important to swim parallel to the shore if caught in a rip current to escape its pull.

Tidal volume is determined by the amount of air moving in and out of the lungs with each normal breath. Factors that can affect tidal volume include lung compliance, respiratory muscle strength, and the body's oxygen demand. High tidal volume may occur during exercise or in conditions such as acute respiratory distress syndrome, while low tidal volume can be seen in conditions like restrictive lung diseases or when a person is at rest.

Longshore drift is evidence of constructive waves. Constructive waves carry and deposit sediment along the coastline, resulting in the movement of sand and material parallel to the shore. This process helps build up beaches and create landforms such as spits and barrier islands.

Ocean tides are the rising and falling of the sea level caused by the gravitational pull of the moon and the sun on the Earth's water bodies. Tides occur in a cyclical pattern due to the rotation of the Earth and the gravitational forces of celestial bodies. They vary in height and timing based on the location and the phase of the moon.

It depends on where you live. Animals that live between high and low tide are adapted for severe fluctuations in salinity, temperature and moisture levels. In the northeast US, typical intertidal animals include green crabs, hermit crabs, periwinkle snails, whelks, mussels, and limpets.

Very simply put.

The tides are an effect of the moons gravity on our oceans and seas. The earth rotates. The gravitational affect of the moon affects different parts of the ocean at different times of the 'day'.

Moon and Sun line up at New Moon and Full Moon to give especially high tides.

High tides occur along the coast of Massachusetts due to the gravitational pull of the moon. Locations such as Cape Cod, Boston Harbor, and Martha's Vineyard experience high tides that vary in timing and height depending on their specific geographic features.

The bulge that occurs on Earth facing or opposite the Moon is called a tidal bulge. This is due to the gravitational attraction between the Earth and the Moon causing a stretching effect on the water on Earth's surface, leading to the formation of high tides.

No. The WORD is related, but not the effect. Spring, the season, is so called because new life "springs" into being (you'll note the other side of the year is the "fall). Spring tides are so called because the WATER springs up to its maximum due to the combined effects of the Sun and Moon (at New and Full). The opposite of spring tide is "neap" tide.

Both the sun and the moon influence tides through their gravitational pull on Earth's water. The moon has a stronger effect because it is closer to Earth and creates larger tidal bulges. The sun's influence is less pronounced but still contributes to variations in tidal patterns, especially in combination with the moon during spring tides.

The mini skirt is often attributed to British fashion designer Mary Quant, who popularized the style in the 1960s as part of the "Swinging London" trend. Quant's innovative design broke away from traditional hemlines and helped symbolize the liberation of women's fashion during that era.

It varies depending on the location, but on average it may take around 6 hours for the tide to change from low tide to high tide.

There are typically two high tides that occur daily in Baffin Bay, as it follows a semi-diurnal tidal pattern. This means that the water level rises and falls twice within a 24-hour period.

An object floating in the ocean will be carried by the currents and waves, drifting with the water. Its movement and eventual destination will be determined by the ocean's circulation patterns and wind conditions.

Both neap tides and spring tides occur due to the gravitational forces of the Moon and the Sun on Earth's oceans. Neap tides happen when the gravitational pull of the Moon and Sun are at right angles, resulting in lower high tides and higher low tides. Spring tides occur when the gravitational pull of the Moon and Sun are aligned, creating higher high tides and lower low tides.

No, magnetism does not directly influence tides. Tides are primarily caused by the gravitational forces between the Earth, the Moon, and the Sun. Magnetism plays a role in other natural phenomena, such as the Earth's magnetic field and magnetic interactions between objects.

The gravitational pull of the moon is the primary physical process responsible for changes in oceanic tides. The moon's gravity causes the water on Earth to bulge out towards the moon, creating high tides. As the Earth rotates, areas not facing the moon experience low tides.

Generally, private property ends at the mean high water mark. However, you may need to check the laws of your particular state. The laws in Florida are being modified where the state has added footage to the beaches for erosion control projects. The state does not consider that added land, which changed the old mean high water mark, as belonging to the abutter and suits have been filed. The added beachfront has been dedicated to the public.

The next high tide would occur approximately 12 hours and 25 minutes later at around 5:25 am the following day. This is because tides typically follow a semi-diurnal pattern, with two high tides and two low tides each day, occurring approximately 12 hours and 25 minutes apart.

The land between low and high tide lines is known as the intertidal zone or littoral zone. This area is alternately covered and uncovered by the ocean's tides, creating a unique and constantly changing environment for marine life.

The red tide can occur in any month of the year. It is not yet clear what triggers the event.

The ocean is filled with unsolved mysteries and has continued to stump scientists with new discoveries everyday. One of the most puzzling issues is the phenomenon known as Red Tide. With records dating back to the mid 1800s, Red Tide has continued to frustrate researchers with the cause of this unusual event (About Red Tide 2005). Although Red Tide has occurred all over the world: Maine, Norway, Africa, Japan and even Oregon, I will be mainly concentrating on the Florida region in order to learn more about this catastrophic act of nature (Hunting Dangerous Algae 2002). First I will discuss some background information on Red Tide and give a brief description on how they can occur and which species are responsible for this disturbing phenomenon. Next I will concentrate on how Red Tide affects not only marine life, but our lives as well. With the wealth of information published about Red Tide, I will only be able to brush upon key aspects of it. With further research and education, someday we may be able to prevent some of the devastation caused by the Red Tide.

Red Tide is caused by a rapid population growth of microscopic plankton. These microscopic plankton release toxins that have severe affects on marine life and humans (Red Tide 2001). The toxins are Environmental chemicals' that can interfere with metabolism, nerve conduction, and the central nervous system (From Monsoons to Microbes 1999). The blooms mainly take place in coastal, warm waters.

Factors that promote red tide occurrences are

1. Warm temperatures

2. High nutrient content

3. Low salinity

4. Calm seas and

5. Rain followed by sunny weather.

As the plankton multiply and grow, they cause a discoloration in the water near the shoreline (Red Tide 2001). Often it turns a reddish-brown color, hence the name red tide. There have been occurrences where the water has turned a yellow, brown, or even a purple shade (Fish and Wildlife Research Institute 2005)

Scientist has summarized the development of Red Tide into four stages. The first stage is where the plankton is introduced into the area. Next is the growth stage where the population begins to multiply rapidly over a few weeks time span. As they reach the peak of growth they enter into stage three, maintenance. Here is where the bloom can either continue to live offshore or can be moved inshore by tides or strong winds. If the bloom moves closer to shore, nutrients are in greater abundance, which can cause the bloom to grow even larger. Finally, the bloom will eventually dissipate, ending the cycle (Red Tide 2001).

Red Tide occurs most often in the Florida region, particularly on the gulf side. Although there are thousands of microscopic species of plankton, one in particular resides only in Florida. The Karenia brevis is a dinoflagellate that was first identified in 1947 (Red Tide 2001). The Karenia brevis has caused most of the red tide occurrences within Florida's gulf waters. The organism is extremely fragile and can break easily when going through rough waves along beaches. They can be broken apart from the tides allowing the toxins to be released into the water (Literature review of Florida red tide 2003).

One of the newest developments in Florida's Red Tide research has been the connection between red tide and the dust storms from Africa. Scientists believe that the dust clouds that travel from the Saharan desert could be triggering these algae blooms. The iron is deposited into the water and then is used by the bacteria called Trichodesmium to fixate nitrogen. Since there is an abundance of nitrogen in the ocean, the water is more susceptible to creating toxic blooms (Dust from Africa 2005).

Organisms involved in Red Tide are not always harmful to the marine life, but unfortunately there is a great number that are. These harmful algal blooms (HABs) have caused death among fish, birds, manatees, and several other vertebrate species. Eating the toxic plankton, eating other organisms already infected with the toxins, or simply by exposure through the water can contaminate organisms (Effects of Florida Red Tide 2005). The toxins do not affect filter-feeding shellfish even though the toxins are concentrated in their organs. Other fish, however, are not so lucky and end up being victims to the powerful red tide (Literature review of Florida red tide 2003).

The death rate of fish during Red Tides has reached extreme numbers. Estimates are that over 100 tons of fish can be killed during a Red Tide in a single day (Literature review of Florida Red tide 2003).

Once the fish is infected, they begin to twist and swim in a corkscrew fashion. They begin to defecate and regurgitate as well as experience convulsions. Their body slowly begins to paralyze and prior to death they begin to experience respiratory failure. This process unfortunately can take from a couple of days to a full week before the organism eventually dies (Effects of Florida Red Tide 2005).

Manatee and dolphin mortality numbers are on the rise due to red tide toxins. In 1996 150 manatees along the Florida region were reported dead over a two-year period from a red tide occurrence (Hunting Dangerous Algae from Space 2002). This single red tide wiped out 10% of the Florida manatee population as well as 162 dolphins within Mexico's waters (START 2004). Along the shoreline of Siesta Key and Lido beaches, there have been at least 44 manatees that have died from coming into contact with red tide (Red Tide Toxins Hit Florida Beachgoers 2005). Although these numbers seem extreme it is the reality of Red Tide. In June 1987 to May 1988 one of the largest dolphin kills was reported along the Atlantic coastline. 740 bottlenose dolphins died from red tide during this period (Effects of Florida Red Tide 2005).

Red Tide has affected humans as well. The impact is both medical and economical. The diagnosis of Red Tides physical affects has been narrowed down into five different types of poisoning. 1. Amnesic Shellfish Poisoning (ASP). Symptoms are vomiting, headache, diarrhea, memory loss, seizure, or even coma. You can get this type of poisoning from eating a contaminated clam or mussel 2. Ciguatera Fish Poisoning (CFP). Symptoms for CFP are skin irritation, temperature reversal, hallucinations, and muscular and joint pain. 3. Diarrheic Shellfish Poisoning (DSP). Symptoms are chills, vomiting, nausea, and diarrhea. Scallops, mussels and short-necked clams cause DSP. 4. Neurotoxin Shellfish Poisoning (NSP). Symptoms for NSP are tingling of limbs, muscle aches, and dizziness. Clams, scallops, mussels, and oysters are all associated with NSP. 5. Paralytic Shellfish Poisoning (PSP). Symptoms are rash, fever, numbness of mouth, drowsiness, and vomiting (Shellfish Poisoning 2005). The earliest record of PSP was in the year of 1793 when a man died and four others were left ill (Saving the Oceans 1992)

From 1978 to 1987, half of the reported seafood poisonings were the result of Red Tide toxins (From Monsoons to Microbes 1999). Becoming contaminated with these toxins can be deadly unless you take necessary precautions. To treat most of the cases, you should go to your local hospital to get your stomach pumped or induce vomiting in order to get the toxins out of your system. If you cannot get to a hospital your best choice is to call the poison control center for further instructions. Eating contaminated shellfish tastes no different than if they were not contaminated. The only way to avoid a Red Tide poison is to be aware and cautious of when and where you eat shellfish (Red Tide 2001).

The economy has also been left to survive the blows of red tide. The West Florida shelf is a hot spot for fishing, aquaculture and tourism, all of which can be drastically affected by a surprise visit from a red tide. (Dust from Africa Leads to Large Toxic Algae Blooms 2005).

Tourism is one of Florida's most profitable businesses. Families don't want to attend a beach where they will suffer an irritating cough and itchy eyes. Restaurants suffer from the lack of tourism and locals refusing to eat out in order to avoid eating something that could be contaminated (Businesses pursue Red Tide solution 2004). Oyster harvesting is another huge business in Florida that is getting hit by HABs lately. On numerous occasions, Florida has had to shut down the oyster industry in Apalachicola Bay because of the threat of red tide contamination (Red tide threatens oyster harvest 2003).

Red Tide has created a large impact on our oceans and our lives. It's increasingly affecting our marine life and our own health and economic prosperity. Programs have been established to try and reduce the harmful effects of the Red Tide and keep people educated about this phenomenon. The next step in coming closer to solving the mystery is more research. Whatever is causing red tide, and the answer behind stopping it is out there. We just have to keep diving deeper for the truth.

there are 732 tides a year! That is about right. But, it depends if it is diurnal, twice a day so 365 x 2 = 730, minus 2 in leap years, 728. if tide is semi-diurnal, then there are 4 tides a day 1,460, and it can be mixed with 3 tides a day.

The sun and moon's gravitational pull on Earth's oceans causes tides. The moon's gravitational pull is stronger due to its proximity, creating two high tides and two low tides each day as the Earth rotates. The sun's gravitational pull also affects tides, with spring tides occurring when the sun, moon, and Earth align, creating higher high tides and lower low tides.
