Dynamics and Characterization of Marine Organic Matter
Over the past decade the scientific acti vities of the Joint Global Ocean Flux Study
(JGOFS), which focuses on the role of the oceans in controlling climate change
via the transport and storage of greenhouse gases and organic matter, have led to
an increased interest in the study ofthe biogeochemistry of organic matter. There
is also a growing interest in global climate fluctuations. This, and the need for a
precise assessment of the dynamics of carbon and other bio-elements, has led to
a demand for an improved understanding of biogeochemical processes and the
chemical characteristics of both particulate and dissolved organic matter in the
ocean.
A large amount of proxy data has been published, describing the changes of
the oceanic environment, but qualitative and quantitative estimates ofthe vertical
flux of (proxy) organic compounds have not been weIl documented. There is thus
an urgent need to pursue this line of study and, to this end, the present book starts
with several papers dealing with the primary production of organic matter in the
upper ocean. Thereafter, the book goes on to follow the flux and characterization
of particulate organic matter, discussed in relation to the primary production in
the euphotic zone and resuspension in the deep waters, including the vertical flux
of proxy organic compounds. It goes on to explain the decomposition and
transformation of organic matter in the ocean environment due to photochemical
and biological agents, and the reactivity ofbulk and specific organic compounds,
including the air-sea interaction of biogenic gases.
The 22 papers in the book reflect the interests of JGOFS and will thus serve
as a valuable reference source for future biogeochemical investigations of both
bio-elements and organic matter in seawater, clarifying the role of the ocean in
global climate change.
All papers deal with the authors' current work in progress and all have been
refereed and revised in accord with the comments received. We would like to
express our thanks to all of the contributors for their patience in waiting for this
publication. We also thank the reviewers who kindly gave the authors critical and
helpful suggestions and comments. Our thanks are also due to the Ministry of
Education, Science, Sport and Culture for the financial support they gave to this
publication.
