Planktonic marine cyanobacteria are abundant and significant in the biogeochemistry of the sea. This volume focuses on the filamentous cyanobacteria, particularly those in the genus Trichodesmium which are common in tropical and subtropical seas. A portion of this book also concerns bloom-forming cyanobacteria in the Baltic Sea area. Filamentous cyanobacteria are important as primary producers and for the fixation of atmospheric nitrogen and thus are significant in global cycling of both of these elements. In recent years, through the application of new techniques and intensive multi-disciplinary research programs, progress has been made in understanding both the biology of these cyanobacteria and their place in the marine food web. A broad range of topics is covered in this book, ranging from molecular biology, physiology, ultrastructure, enzyme localization, toxicology, remote sensing, buoyancy, herbivory and the ecology of these organisms in the marine food web. This volume is an outgrowth of a NATO-sponsored meeting held in May 1991 in Bamberg, Germany, and represents the latest synthesis on these marine phytoplankters

This volume presents an up-to-date account of the phytoplankton blooms which have recently occurred on a world-wide basis, particularly the new "brown tides" along the coasts of several northeastern American states. The individual chapters detail the known causes of these blooms as well as the impacts on important fisheries and other components of the ecosystem such as other plankton and eelgrass meadows. Environmental management concerns, strategies and programs are also presented. This volume will bring the reader up-to-date in terms of scientific knowledge, hypotheses, and new state-of-the-art techniques being employed to investigate microalgae and the environmental conditions conducive to blooms
