Shallow Seas (Collins New Naturalist Library, Volume 131)

Peter J. Hayward


Shallow Seas are the main biologically wealthy and efficient parts of the area ocean. This most modern New Naturalist quantity presents a common historical past of this atmosphere and its organic groups. The margins of the continents, specially extensive within the North Atlantic quarter, are drowned through shallow seas, making a sea flooring setting that's a part of the broader and deepening benthic realm – the ecological quarter on the lowest point of a physique of water reminiscent of an ocean or a lake, together with the sediment floor and a few sub-surface layers. those 'shelf seas' are the main biologically wealthy and effective components of the realm ocean. In his most recent New Naturalist quantity, Peter Hayward addresses a few points of the usual historical past of the benthic surroundings of the shelf seas of northwest Europe and its organic groups. clear of rocky coastlines the seafloor is quite flat, usually muddy, underneath turbid water with low or no visibility. Benthic faunas as a rule reside in the sediment of the seafloor, or are carefully and patchily disbursed upon it, and if in any respect motile tend to withdraw into burrows or circulation fast away on disturbance. but, dredges and grabs exhibit a regularly remarkable range and density of animals, suggestive of complicated interacting groups. this isn't a textbook of marine benthic ecology, neither is it a complete evaluation of the benthic groups of the northwest eu shelf seas. quite, it describes the traditional historical past of a few benthic habitats and institutions attribute of our quarter.
