The tidal range is the vertical difference between the high tide and the succeeding low tide. Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth. The tidal range is not constant, but changes depending on where the sun and the moon are.
The most extreme tidal range occurs around the time of the full or new moons, when the gravitational forces of both the Sun and Moon are in phase, reinforcing each other in the same direction (new moon), or are exactly the opposite phase (full). This type of tide is known as a spring tide. During neap tides, when the Moon and Sun's gravitational force vectors act in quadrature (making a right angle to the Earth's orbit), the difference between high and low tides is smaller. Neap tides occur during the first and last quarters of the moon's phases. The largest annual tidal range can be expected around the time of the equinox, if coincidental with a spring tide.
Tides are the periodic rise and fall of sea levels caused by the gravitational forces exerted by the Moon and the Sun. When there is a new moon or full moon, the sun, moon and earth are aligned. The higher gravitational pull of these combined forces results in higher than normal high tides and lower than normal low tides. These are called Spring Tides. During the moon's quarter phases, the line from the Earth to the Moon is at right angles to the line from the Earth to the Sun. Consequently the tide generating forces of the sun and moon oppose each other, thereby producing tidal ranges that are approximately 20% lower than the mean tidal range. We call these Neap Tides.
The Hopewell Rocks Tidal Exploration Site is a fantastic place to experience the Bay of Fundy's world famous tides. To help our guests understand a full tide cycle, we set up a camera and took 1 photograph per minute from before sunrise until after sunset. The resulting 926 photos were then each used as a frame of video to create this glimpse of the world's largest tides. To fully appreciate this natural wonder, come spend a day with us on the ocean floor. For more infoormation, visit http://www.thehopewellrocks.ca Video created by http://www.creativeimagery.ca

The world's hjghest tides occur in the Bay of Fundy in Atlantic Canada. This time lapse movie speeds up by 720 times the fall and rise of the tide in Hall's Harbour, Nova Scotia.
Time-lapse video of the Bay of Fundy tide rising from low to high at Herring Cove in Fundy National Park, New Brunswick, Canada. Don't have 6 hours to sit and watch the incredible Bay of Fundy tide? I have compressed the whole tide into 1.5 minutes for you to see. This is a dramatic way to see the incredible magnitude of the Bay of Fundy tide. The tidal range at this part of the bay is about 12 metres. The low tide is so far away from the high tide line on the beach that it is difficult to see what is happening until the water gets closer. I started with a camera position closer to low tide to show the beginning more clearly but knowing I would have to move to higher ground before I got trapped by the tide. Then I moved the camera to a new position for the remainder of the tide. This wa...
Time-lapse video of the Bay of Fundy tide at Point Wolfe, Fundy National Park, New Brunswick, Canada. This vantage point on the Shiphaven Trail is THE most spectacular location in Fundy National Park to see the full range of the tide. You would have to sit here for 6 hours and 10 minutes to experience this, but every minute would be worth it. You really have to experience the Fundy tide for yourself to fully grasp the magnitude of it. This is just one inlet, but imagine every river, inlet, and cove, not to mention the entire Bay of Fundy filling up with an additional 12 metres of water in 6 hours. It's mind boggling. In fact, I can't imagine why you're not here right now to check it out for yourself. This was shot as continuous video and then sped up 25,000% to compress it into one mi...
If you need the height of the tide for a particular time, for example for 13:00, just enter the required time at the timescale grid. 13:00 is roughly 3 hours after high tide. Then check whether the tidal range is close to a spring range or neap range. In our case we have a tidal range of 3.8 meters; 4.2 - 0.4 equals 3.8 meters. As we can see from the mean ranges, 3.8 meters is close to a spring range. Next we draw a line from 3 hours after high water to the spring curve. Here we can interpolate by eye. From the intersection of the line and the spring curve we draw a horizontal line to the high and low water line. From here we draw a line to join the top scale. The number at this point is the height above chart datum of the tide at the required time. To calculate the total depth of...
Sydney designer Trent Jansen reflected on the aesthetics of Australian summers in the 1970s to create this sunlounger for outdoor furniture brand Tait (+ slideshow). Made from stainless steel wire, the Tidal sunlounger references the shape of vintage metal poolside daybeds, but updates it with a more curved, black design. "When developing ideas, I was considering that it should perhaps be reminiscent of the summertime, and in particular the 1970s and summer holidays in that sort of period of Australia's history," said Jansen. Designed to be used with a cushion on top, the sunlounger is part of a wider collection of chairs and tables created by Jansen for Australian company Tait. The pieces are all made from similarly bent 12 millimetre stainless steel rods. Jansen found inspiration for...
Tidal Irrigation is the subsurface irrigation of levee soils in coastal plains with river water under tidal influence.It is applied in arid zones at the mouth of a large river estuary or delta where a considerable tidal range is present.The river discharge must be large enough to guarantee a sufficient flow of fresh water into the sea so that no salt water intrusion occurs in the river mouth.The irrigation is effectuated by digging tidal canals from the river shore into the main land that will guide the river water inland at high tide.

king tides occur when the Earth, Moon and Sun are aligned at perigee and perihelion, resulting in the largest tidal range seen over the course of a year. This video was taken at about 8:00 AM in the Sunset Beach area on November 24, 2015. King tides are a normal occurrence once or twice every year in coastal areas
The project 'For whom the tides toll 2.0' refers in many ways to the area around DordtYart where water, ships, nature reserve Biesbosch and religion play a leading role. Characteristic for this area is the large tidal range which can reach more than 1 meter. The artist uses various ways to thematize the dichotomy between nature in technology or nature versus culture and tries to synchronize the sculptural elements in new order, time and rhytm. The system of wooden air ducts used in this mechatronic sculture is an abstract map of the five major waters in the Biesbosch area. The air blown through the channels is entering the organ pipes that produce the sound. The tone is changing according to the tides change that is different each day. The biotope includes plants that placed in front of th...
Leading up to International Conference on Ocean Energy (ICOE 2014) in Halifax, Annex IV sponsored an environmental webinar focused on tidal energy research associated with the Bay of Fundy tidal site. Due to its geographic location and the overall shape of its basin, the Bay of Fundy is home to the largest tidal ranges in the world, reaching over 16 meters. With such an enormous tidal range, substantial amounts of water moves through this bay every day making it an exceptional tidal energy resource. This webinar highlights the work being done by four scientists who focus their research on better understanding the tidal energy resource and potential in the Bay of Fundy, and how tidal energy developments there may affect the surrounding marine environment. Held on October 27, 2014 More info...

http://erenewableenergyinfo.com Dr. Polagye's research focuses on responsibly harnessing the kinetic energy in moving water. In particular, he is developing a better understanding of the practically recoverable resource from tidal streams through numerical modeling and field measurements. In-stream energy extraction is numerically modeled over a variety of scales, from an entire estuary down to a single device. At the estuarine scale, kinetic power extraction leads to a number of far-field effects, including changes to the tidal range, volume flow rate, and power dissipation. Each of these effects has important environmental, social, and economic consequences for in-stream developments. At the device scale, a better understanding of wake mixing is needed to establish rules for device spac...

As a collaborative program between CIFOR and US Forest Services, SWAMP has entered its third year and been implemented in 24 countries. The activities range from field campaign, capacity building and policy dialogues in countries where significant size of wetland ecosystems including peatlands and mangroves are found. Today, we will learn how significant it is to include mangroves in climate change mitigation and adaptation strategies. They store carbon as much as 5-6 times higher than lowland tropical forests could significantly mitigate climate change. These storage is mainly the soil (80%) so that they need special attention with regard to land-use change, especially for aquaculture development. Mangroves also offer protection of coastal zone from sea level rise. Learn more: http://www....

Moreton Bay is a bay on the eastern coast of Australia 14 km from central Brisbane, Queensland. It is one of Queensland's most important coastal resources. The waters of Moreton Bay are a popular destination for recreational anglers and are used by commercial operators who provide seafood to market. The Port of Brisbane coordinates large traffic along the shipping channel which crosses the northern section of the bay. The bay serves as a safe approach to the airport and reduces noise pollution over the city to the west of the runway. A number of barge, ferry and water-taxi services also travel over the bay. Moreton Bay was the site of conflict between indigenous Australians and early European settlers. It contains environmentally significant habitats and large areas of sandbanks. The bay...
