What are pelagic environments?

The pelagic environment is that of the water column, from the sea surface to the waters immediately above the seafloor; From: Biological Oceanography: An Introduction (Second Edition), 1997.

What is meant by pelagic habitat?

The pelagic zone refers to open and free waters in the body of the ocean that stretch between the ocean surface and the ocean bottom and are not too close to some boundary, like a shore or the seafloor or the surface.

What is the pelagic environment made of?

The pelagic environment comprises the entire water column. Of all the inhabited environments on Earth it is by far the largest and most diverse, ranging from the surface photic zone to the abyssal depths where life exists in total darkness and at huge pressure.

Where is the pelagic zone?

The pelagic zone is the part of the open sea or ocean comprising the water column, i.e., all of the sea other than that near the coast or the sea floor. In contrast, the demersal zone comprises the water that is near to (and is significantly affected by) the coast or the sea floor.

What are the 5 pelagic zones?

The pelagic zone is divided into epipelagic, mesopelagic, bathypelagic, abyssopelagic, and hadopelagic zones.

What are the main characteristics of the pelagic environment?

The regional and vertical distributions of pelagic life are governed by the abundance of nutrients and dissolved oxygen; the presence or absence of sunlight, water temperature, salinity, and pressure; and the presence of continental or submarine topographic barriers.

Where is pelagic made?

Founded in 2002, off the coast of Newport Beach (California), PELAGIC is deeply rooted in fishing and ocean culture. Inspired by a love for the offshore lifestyle and the need for a brand that professional captains, mates, deckhands, and waterman could hold on to – PELAGIC was born.

What types of organisms are most prevalent in the pelagic environment?

27.6.

The pelagic ecosystem is well known for its emblematic species such as sharks, marine mammals, and tuna. However, this system is highly dependent on components of the food web that are based on primary production by phytoplankton (Box 27.1), which sustains zooplankton, micronekton, and large nektonic fauna.

What is the climate of the pelagic zone?

The water temperature stays fairly constant down here between about 2-4 degrees C, (about 35-39 degrees F).

What are the two zones in the pelagic environment?

The pelagic zone has two main subdivisions: neritic zone and oceanic zone.

What plants live in the pelagic zone?

Photosynthetic plants such as phytoplanktons, dinoflagellates and algae live in the pelagic zone. They exist in unicellular, multicellular or colonial forms.

What species are found in pelagic?

Examples of species include forage fish such as anchovies, sardines, shad, and menhaden and the predatory fish that feed on them. Oceanic pelagic fish typically inhabit waters below the continental shelf. Examples include larger fish such as swordfish, tuna, mackerel, and even sharks.

How is pelagic sediment formed?

Pelagic sediment or pelagite is a fine-grained sediment that accumulates as the result of the settling of particles to the floor of the open ocean, far from land. ... The second factor is water depth, which affects the preservation of both siliceous and calcareous biogenic particles as they settle to the ocean bottom.

How does the physical environment of the pelagic zone change with depth?

How does the physical environment of the pelagic zone change with depth? Coral reefs only make up a small percentage of the oceans, covering about one percent of the ocean floor. The wave's period increases.
