changing with the tides

Product Information

Wind and weather patterns also can affect water level. Strong offshore winds can move water away from coastlines, exaggerating low tides. Onshore winds can push water onto the shore, making low tides much less noticeable. Researchers are also using computer models to analyse how changing tides and rising sea levels might affect other types of coastal flooding. A hurricane’s storm surge, for instance, often responds to the changing landscape much as tides do. The moon’s tidal force has a much greater effect on the surface of the ocean, of course. Water is liquid and can respond to gravity more dramatically. It was the muddy water that caught Stefan Talke’s eye. In the mid-2000s Talke was a postdoctoral scholar at Utrecht University, studying the river Ems that empties into the North Sea between Germany and the Netherlands. Decades earlier, engineers had begun dredging parts of the Ems so that newly built ships could navigate it from a shipyard upriver. Intertidal zones are marked by vertical zonation. Different organisms live in different zones in the tidal range, depending on how much water reaches them. This zonation can often be seen vertically, with dry plants near the top of the tidal zone and seaweeds near the bottom.

Rising and ebbing tides happen as Earth’s landmasses rotate through the tidal bulges created by the Moon’s gravitational pull. Our observer sees the tides rise when passing through the bulges, and fall when passing through the low points. Of course, in reality the Earth isn’t a smooth ball, so tides are also affected by the presence of continents, the shape of the Earth, the depth of the ocean in different locations, and more. The timing and heights of the tide near you will be affected by those additional elements. The result of the tidal force is a stretching and squashing of Earth. This is what causes the two tidal bulges.The Moon and Earth exert a gravitational pull on each other. On Earth, the Moon’s gravitational pull causes the oceans to bulge out on both the side closest to the Moon and the side farthest from the Moon. These bulges create high tides. The low points are where low tides occur. When there is a low tide, the Moon faces the Earth at a right angle to the Sun so the gravitational force of the Moon and Sun work against each other. These tides are referred to as neap tides; a low tide or one that is lower than average. A neap tide happens between two spring tides and occurs twice a month when the first and last quarter Moon appears. Spring tides If sea level were to rise between 0.5m and 2.1m (1.6-6.9ft) in the delta, then cities in its upstream reaches would see tidal increases between 0.1m and 0.5m (0.3ft and 1.6ft), the scientists found. Add those numbers together and it looks as if water levels could go up between 0.6m and 2.6m (2-8.5ft). Tides are really all about gravity, and when we're talking about the daily tides, it's the moon's gravity that's causing them. In the open ocean, the tidal force of the moon will appear as bulges of water facing the moon whereas around land mass the water can spread out onto land creating tides. Types of tides

Arrows represent the tidal force. It's what's left over after removing the moon's average gravitational pull on the whole planet from the moon's specific gravitational pull at each location on Earth. In the mid-2000s Talke was a postdoctoral scholar at Utrecht University, studying the Ems River that empties into the North Sea between Germany and the Netherlands. Decades earlier, engineers had begun dredging parts of the Ems so that newly built ships could navigate it from a shipyard upriver. The tidal range along the Thames River has quadrupled since the time of the Romans, as engineers narrowed and deepened the river for navigation. Those tides rhythmically submerged and revealed the Rising Tide sculpture, underwater artist Jason deCaires Taylor’s 2015 installation at Vauxhall in London. Another aspect I really identified with was the idea of using writing to heal, while still being vulnerable and open about one's own weaknesses. For instance, this small gem:

The intertidal zone can be further divided into three zones: high tide, middle tide, and low tide. The high tide zone is only submerged at high tide and is hotter and drier as a result. The middle tide zone is submerged and exposed for equal amounts of time. The low tide zone is only exposed during low tide and has the greatest biodiversity of the three zones because it provides more favorable conditions for those organisms that cannot tolerate air exposure for long.

When the moon's gravity pulls on the water in the oceans, however, someone's bound to notice. Water has a much easier time moving around, and the water wants to bulge in the direction of the moon. This is called the tidal force. But those changes also changed the rhythm with which tides ebbed and flowed into the river from the sea. Those shifting tides stirred up sediment from the river bottom and muddied its waters. Over the last 120 years the tidal range – the distance between high and low tide – has quintupled in the Ems estuary. As the Earth rotates, your region of Earth passes through both of these bulges each day. When you're in one of the bulges, you experience a high tide. When you're not in one of the bulges, you experience a low tide. This cycle of two high tides and two low tides occurs most days on most of the coastlines of the world.
