This book integrates a variety of issues such as regional settings of productivity and nutrient cycling; plankton of coastal and shelf systems; plankton, climate change and human-induced changes; harmful algae and their impacts; and gelatinous zooplankton. This book explores the intriguing marine plankton communities of the SWA region of South America encompassing low to high latitude environments, framed by a complex hydrographic background and global climate change. This vast and iconic region has been largely under-recognized and under-studied. However, in recent years a strong interest has emerged along with the acknowledgment of its high biological productivity. The book concludes by discussing conservation in the region, highlighting regional biodiversity hotspots where the challenges of climate change, habitat loss, and other threats to biodiversity may be particularly acute. Plankton Ecology of the Southwestern Atlantic is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both researchers and graduate students, and will also be of interest and use to a professional audience of oceanographers, conservation biologists, stake holders and educated science enthusiasts

With contributions from an impressive group of Argentinean and German oceanographers, this book examines classical ecological issues relating to marine ecosystems in the context of climate change. It paints a picture of marine ecology at the crossroads of global warming. The book examines the fundamentals of marine ecology: ecosystem stability, water quality, and biodiversity in the context of the changes taking place globally. It then reviews the major marine ecosystems in the same context, from the primary producers to the big marine mammals. The chapters cover primary consumers level, benthic communities, seaweeds assemblages and wetlands ecology, fisheries, and seabirds.

Rocas Alijos lies 180 nautical miles west of Baja California. It comprises several exposed rocks that surmount a large oceanic volcano rising from the ocean floor well off the continental shelf. It is located at the transition zone between two major biologic provinces, at a latitude where the Pacific Current turns westward to form the north Pacific trans-oceanic current. In spite of its obvious importance for biogeographical studies, the remoteness of Rocas Alijos and its small size thwarted any major scientific work until very recently, and the topography, biota, and oceanographic conditions of the site remained largely unknown. During 1990, and again in 1993, Cordell Expeditions, a nonprofit research organization based in Walnut Creek, California, undertook expeditions to describe the site. A scientific team of 30 was onsite 31 October-7 November 1990, and a scientific team of 12 was onsite 10-15 February 1993. Since most of the Rocas Alijos site is subtidal, much of the examination and specimen collection was done by scuba, although several remote sampling techniques were also used. The exposed rocks were sampled by climbers, and megafauna were observed from shipboard.

Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.

From a study of knowledge of the sea among indigenous cultures in the South Seas to inquiries into the subject of sea monsters, from studies of Pacific currents to descriptions of ocean-going research vessels, the sixty-three essays presented here reflect the scientific complexity and richness of social relationships that characterize ocean-ographic history. Based on papers presented at the Fifth International Congress on the History of Oceanography held at the Scripps Institution of Oceanography (the first ICHO meeting following the cessation of the Cold War), the volume features an unusual breadth of contributions. Oceanography itself involves the full spectrum of physical, biological, and earth sciences in their formal, empirical, and applied manifestations. The contributors to Oceanographic History: The Pacific and Beyond undertake the interdisciplinary task of telling the story of oceanography’s past, drawing on diverse methodologies. Their essays explore the concepts, techniques, and technologies of oceanography, as well as the social, economic, and institutional determinants of oceanographic history. Although focused on the Pacific, the geographic range of subjects is global and includes Micronesia, East Africa, and Antarctica; the bathymetric range comprises inshore fisheries, coral reefs, and the "azoic zone." The seventy-one contributors represent every continent of the globe except Antarctica, bringing together material on the history of oceanography never before published.

The Strait of Gibraltar is the unique and narrow connection between the Mediterranean basin and the open Atlantic Ocean. One of the main features of this place is the strong topographic constriction that happens both in the horizontal and vertical dimension in conjunction with the presence of a two-layered counter-current circulation and strong inequalities of the tidal range at both sides. These differences in tidal amplitude induce intense barotropic and baroclinic currents which interact with the sharp sea-bottom topography in the main sill of the Strait to create internal waves in the Atlantic-Mediterranean Interface (AMI). This book presents a comprehensive review of the most recent findings, along with some directions for future research necessary to enhance our knowledge of the tidal influence on the inter-basin biogeochemical budget.

Fjords are glacially over-deepened, semi-enclosed marine basins, but are often neglected as a sedimentary realm. They represent the transition from the terrestrial to the marine environment and as such have the potential to preserve evidence of environmental change. Typically most fjords have been glaciated a number of times and some high-latitude fjords still possess a resident glacier. The stratigraphic record in fjords largely preserves a glacial-deglacial cycle of deposition. Sheltered water and high sedimentation rates potentially make fjords ideal depositional environments for preserving continuous records of climate and environmental change with high temporal resolution. Fjords are also referred to as miniature oceans providing the unique opportunity to study marine processes in great detail. With predictions of warming climates, changing ocean circulation and rising sea levels, this volume is a timely look at these environmentally sensitive coastlines.

During the intensification of research activities in the Southern Ocean in recent years, both at national levels and through international cooperation in such projects as BIOMASS with its FIBEX and SIBEX phases, the need was felt increasingly for closer collaboration between biologists, meteorologists, and oceanographers in the study of the interaction between the atmospheric forces, the water masses, and the living resources. Better knowledge in this regard is not only of scientific interest but also of practical importance, especially for the management of the resources and the protection of the Antarctic marine ecosystem. As a follow-up on a recommendation by the IOC Program Group for the Southern Oceans made in March 1983, the Intergovernmental Oceanographic Commission organized a meeting of experts on oceanography related to the dynamics of the Antarctic ecosystems. During this meeting, held in Kiel, Federal Republic of Ger many, in May 1984, biologists and oceanographers involved in BIOMASS activities met with the oceanographers of SCOR Working Group 74 to discuss ways and means for additional physical and chemical observations in the oceanographic research within BIOMASS. It was the time when large fluctuations in the distribution of krill with subsequent detrimental effects on predator species dependent on krill had just been observed, and the question arose whether this was possibly the result of changes in the Antarctic water circulation.
