Chemical biomarkers in aquatic ecosystems is a significant contribution to the field of organic biogeochemistry the combined discussions of both the biochemical formation of the biomarkers as well as of their utility as process indicators is of particular importance and almost unique to this book thus the reader will be able to understand the biogeochemical basis for the use of these compounds as biomarkers rather than taking their applicability on faith this alone is a .

Defining a chemical biomarker as a compound that can be linked to particular sources of organic matter identified in the sediment record the book indicates that the application of these biomarkers for an understanding of aquatic ecosystems consists of a biogeochemical approach that has been quite successful but underused this book offers a wide ranging guide to the broad diversity of these .
