Description

Published by the American Geophysical Union as part of the Lecture Notes on Coastal and Estuarine Studies Series, Volume 31.

Most of the seabed throughout the world's oceans is covered with sediment. Sediments are a complex mixture of organic and inorganic materials derived from marine and terrestrial sources. A diverse array of organisms live in sediments, and by far the majority of them derive their nutrition from the organic matter present in the sedimentary deposit. These "deposit feeders" have been studied from a variety of perspectives, ranging from their contribution to the decomposition and remineralization of organic matter reaching the sediments, to their importance as food items to commercially important fishery resources.

In this book, the basic goal of the contributing authors has been to identify the critical research problems pertaining to deposit feeders, and to suggest promising approaches for dealing with those problems. In many cases, the reader will find that the problems and possible solutions discussed in the study of marine deposit feeders have applications to other organisms which face the same general problem of obtaining sufficient nutritional resources from food-poor environments. It is also apparent that much future research on deposit feeders will depend on the integration of such disparate areas of research as nutritional physiology and sediment geochemistry.
