Intertidal Zone: Definition, Characteristics & Facts The intertidal zone is the area of the ocean between the high tide and low tide lines, usually on the beach at the water's edge. If you think of the line created at high tide as the upper limit and the line created at low tide as the lower limit, the intertidal zone is everything between those lines.

Littoral zone Littoral zone, marine ecological realm that experiences the effects of tidal and longshore currents and breaking waves to a depth of 5 to 10 metres (16 to 33 feet) below the low-tide level, depending on the intensity of storm waves.

Intertidal Zone Intertidal zone on a rocky shore, with plants and animals typically found there. The intertidal zone is the area of the marine shoreline that is exposed to air at low tide, and covered with seawater when the tide is high.

- Prof. Stephen A. Nelson. Coastal Zones. A coastal zone is the interface between the land and water. These zones are important because a majority of the world's population inhabit such zones. Coastal zones are continually changing because of the dynamic interaction between the oceans and the land.Waves and winds along the coast are both eroding rock and depositing sediment on a continuous basis, and rates of erosion and deposition vary considerably from day to day along such zones. The tidal bulges result in a rhythmic rise and fall of ocean surface, which is not noticeable to someone on a boat at sea, but is magnified along the coasts. 2  Usually there are two high tides and two low tides each day, and thus a variation in sea level as the tidal bulge passes through each point on the Earth's surface.

Introduction Organisms in the intertidal zone are adapted to an environment of harsh extremes. Water is available regularly with the tides but varies from fresh with rain to highly saline and dry salt with drying between tidal inundations. The action of waves can dislodge residents from the littoral zone.

Abyssal zone The abyssal zone or abyssopelagic is a layer of the pelagic zone of the ocean. Abyss derives from the Greek word ἄβυσσος, meaning bottomless. At depths of 4,000 to 6,000 metres (13,000 to 20,000 ft), this zone remains in perpetual darkness and never receives daylight. These regions are also characterised by continuous cold and lack of nutrients.The abyssal zone has temperatures around 2 to 3 °C (36 to 37 °F) through the large majority of its mass. It is the deeper part of the midnight zone which starts in the bathypelagic waters above.

Pelagic zone Any water in a sea or lake that is neither close to the bottom nor near the shore can be said to be in the pelagic zone. The word pelagic is derived from Greek πέλαγος (pélagos), meaning 'open sea'. The pelagic zone can be thought of in terms of an imaginary cylinder or water column that goes from the surface of the sea almost to the bottom.

- Epipelagic Zone-The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters (656 feet).It is also known as the sunlight zone because this is where most of the visible light exists.pipelagic Zone-The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters (656 feet).

- Intertidal Zone. The intertidal zone is defined as the area between the high tide and low tide mark. Organisms that live in this zone have to deal with difficult environmental conditions, being both submerged in sea water and exposed to the air.They have to bear the great physical impact of waves, desiccation, and sunlight.he intertidal zone is defined as the area between the high tide and low tide mark.

Littoral zone In oceanography and marine biology[edit] The littoral zone of an ocean is the area close to the shore and extending out to the edge of the continental shelf. The intertidal zone of a beach is also part of the littoral zone. Estuaries are also in the littoral zone.

Littoral zone 1 The infralittoral zone is the algal dominated zone to maybe five metres below the low water mark. 2  The circalittoral zone is the region beyond the infralittoral, which is dominated by sessile animals such as oysters. 3  The subtidal zone is sometimes defined as the shallower region of the neritic zone close to the shore.n physical oceanography, the sublittoral zone refers to coastal regions with significant tidal flows and energy dissipation, including non-linear flows, internal waves, river outflows and ocean fronts.

Intertidal Zone The intertidal is home to a wide variety of organisms. Organisms in this zone have many adaptations that allow them to survive in this challenging, ever-changing environment. Moisture: There are usually two high tides and two low tides each day.

Intertidal zone The intertidal zone, also known as the foreshore and seashore and sometimes referred to as the littoral zone, is the area that is above water at low tide and under water at high tide (in other words, the area between tide marks).he area can be a narrow strip, as in Pacific islands that have only a narrow tidal range, or can include many meters of shoreline where shallow beach slopes interact with high tidal excursion. Organisms in the intertidal zone are adapted to an environment of harsh extremes.

- Subtidal Zone – The intertidal zone is the area below the low tide water line. This area is always covered by water. This area can include many different types of habitats, including soft and hard bottom, submerged aquatic vegetation beds and coral reefs.ast Updated on: 06-24-2008. Estuaries can also be divided into tidal zones (supratidal, intertidal and subtidal zone) subject to changing water levels, temperature, oxygen content and levels of light.

Littoral zone The eulittoral zone (also called the midlittoral or mediolittoral zone) is the intertidal zone also known as the foreshore. It extends from the spring high tide line, which is rarely inundated, to the spring low tide line, which is rarely not inundated.

intermodal Definition of intermodal: Movement of containerized (unitized) cargo over air, land, or sea through the use of different transport modes (aircraft, truck, rail, boats, ships, barges, etc.) capable of handling containers. Knowing what the predicted time for your intermodal process is will help you to plan out how to proceed with things.
