Opis

The papers gathered in this authoritative volume, partly based on presentations by 60 scientists attending a NATO Advanced Research Workshop on Past and Present Water Column Anoxia in Sevastopol, Ukraine, address the entire range of oxygen-deficient conditions and reflect the complexity of the issues governing the formation and persistence of oxygen-deficient and anoxic conditions in the world's ocean throughout history. An additional special feature of this book are review papers by the most respected specialists in their fields that aim to further discussion of the current state of, and future directions of, research on pelagic suboxic and anoxic environments.
