Buch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Life on Earth emerged under anaerobic conditions. Many fundamental b- chemical and metabolic pathways evolved before the atmosphere contained oxygen. Today, anaerobic (anoxic) conditions in marine milieus are generally restricted to sediments and to basins isolated from oxygenated deep-sea cir- lation. Oxygen-de cientorhypoxicconditionsarede nedinoperationalterms. In speaking of the degree of O -de ciency, the term hypoxic is usually de ned 2 as ranging between 22 and 64 MofO , while suboxic refers to a range below 2 10 M, and anoxic is the complete absence of oxygen. Biologists commonly use the term hypoxia to describe the point at which animals suffocate. But the papers presented in this book deal with the whole range of oxygen-de cient conditions, and the de nitions some authors have used here may vary. Enhanced oxygen consumption by decomposition of organic matter and slow downward mixing and diffusion of dissolved oxygen from the surface waters can lead to oxygen de ciency in the water column in highly productive waters, forming the Oxygen Minimum Zone (OMZ). Bottom waters of coastal upwelling regions are frequently exposed to hypoxic (suboxic) or anaerobic conditions owing to extremely high primary productivity. The development of these conditions represents an acute perturbation to ecological dynamics and sheries. Inthepast,anoxicconditionsinthewatercolumnmayhavedeveloped morereadily.
