Ecological Processes at Marine Fronts

This book reviews and summarizes the results and hypotheses raised by studies directly or indirectly dealing with the ecology of fronts and aims to identify the themes that connect them to produce a synthesis of this knowledge. Though not immediately perceived the ocean is highly structured and fronts are one of the most important components of its structural complexity. Marine fronts have been known since the early 20th Century, however, the more recent availability of high resolution satellite imagery, field measurements and numerical simulations have greatly advanced our understanding of their ecological impact. This work touches on topics such as front types, its biology and its comparisons with other bounderies at sea, as well as comparisons of fronts with terrestrial boundaries and the 'ecotone' concept. Furthermore, it also looks at the management and conservation of marine life.

Summarizes relevant studies on biological oceanography and ecology of marine fronts Broadens the understanding of the number and types of ecological processes associated to marine fronts Clarifies the main differences between terrestrial and marine ecosystems for primary production, and explains why climate change would differentially affect such biotopes Includes supplementary material: sn.pub/extras

E. Marcelo Acha is a biologist; his research interests focus primarily on plankton ecology, fish reproduction and ichthyoplankton. His current research activities are related to the role of marine fronts on diversity and biological production of the Argentine Sea, and its effects on the life histories of the species in the region. He is currently member of the National Council of Scientific of Scientific Research and Technology (CONICET); member of the Fisheries Ecology Project (INIDEP), and develops teaching activities at the Mar del Plata University (Argentina). Alberto R. Piola is a physical oceanographer; was Visiting Investigator at the Woods Hole Oceanographic Institution and Research Staff at Lamont-Doherty Earth Observatory of Columbia University. He is currently Research Director at Servicio de Hidrografia Naval, Argentina and Professor of Oceanography at Universidad de Buenos Aires, Argentina. His research is focused on the large scale ocean circulation, regional oceanography and the biological and biogeochemical impacts of ocean fronts. Oscar O. Iribarne is an ecologist; his research interests focus primarily on understanding the role of ecological processes in determining diversity and secondary production on marine ecosystems. He is currently member of the National Council of Scientific Research and Technology (CONICET, Argentina), full Professor at the National University of Mar del Plata (UNMDP, Argentina) and Director of the Institute of Marine and Costal Research (IIMyC, Argentina). Hermes W. Mianzan was a biologist dedicated primarily to the study of the ecology of gelatinous plankton. He was one of the leaders in thought and practice as the vision of planktonic dynamics grew to increasingly incorporate interactions between physical and biological processes, particularly involving his specialty of gelatinous zooplankton in marine fronts. He was member of the National Council of Scientific of Scientific Research and Technology (CONICET); and director of the Fisheries Ecology Project (INIDEP). He taught a variety of courses in Universities of Argentina and of Latin America.
