To all those sailors / Who dreamed before us / Of another way to sail the oceans. The dedication of this Volume is meant to recall, and honour, the bold pioneers of ocean exploration, ancient as well as modern. As a marine scientist, dealing with the oceans through the complex tools, ?lters and mechanisms of contemporary research, I have always wondered what it was like, in centuries past, to look at that vast ho- zon with the naked eye, not knowing what was ahead, and yet to sail on. I have tried to imagine what ancient sailors felt, when “the unknown swirls around and engulfs the mind”, as a forgotten author simply described the brave, perhaps reckless, act of facing such a hostile, menacing and yet fascinating adventure. Innovation has always been the key element, I think, for their success: another way, a better way, a more effective, safer and worthier way was the proper answer to the challenge. The map of our world has been changed time and again, from the geographical as well as the social, economic and scienti?c points of view, by the new discoveries of those sailors. One of the positive qualities of human beings is without doubt the inborn desire to expand their horizons, to see what lies beyond, to learn and understand.

This book represents an outgrowth of an interdisciplinary session held at the Seventh International Estuarine Research Federation Conference held at Virginia Beach, Virginia, OCLober 1983. At that meeting, the participants agreed to contribute to and develop a monograph entitled "Tidal Mixing and Plankton Dynamics" by inviting an expanded group of authors to contribute chapters on this theme. The emphasis would be to review and summarize the considerable body of knowledge that has accumulated over the last decade or so on the fundamental role tidal mixing plays in energetic shallow seas and estuaries in stimulating and controlling biological production. We have attempted to provide a mix of contributions, composed of reviews of the state-of-the-art, reports on current research activi ties, summaries of the design and testing of a new generation of innovative instruments for biological and chemical sampling and sorting, and some imaginative ideas for future experiments on stimulated mixing in continental shelf seas. We encouraged the contributors to present critical and thought provoking assessments of current wisdom specifying the sorts of techniques and observational strategies needed to validate the various hypotheses linking physical structure, mixing and circulation to plankton biomass and production. We hope this volume will appeal to incoming research students and established scholars alike. We certainly have enjoyed working with all the authors in compiling this book. We thank the numerous scientists who have served as reviewers, P. Boisvert for typing the manuscripts and W. Bellows for proofreading.

In this document, the first three years of a time series of bio-optical marine and atmospheric measurements are presented and analyzed. These measurements were performed from an oceanographic tower in the northern Adriatic Sea within the framework of the Coastal Atmosphere and Sea Time Series (CoASTS) project, an ocean color calibration and validation activity. The data set collected includes spectral measurements of the in-water apparent (diffuse attenuation coefficient, reflectance, Q-factor, etc.) and inherent (absorption and scattering coefficients) optical properties, as well as the concentrations of the main optical components (pigment and suspended matter concentrations). Clear seasonal patterns are exhibited by the marine quantities on which an appreciable short-term variability (on the order of a half day to one day) is superimposed. This short-term variability is well correlated with the changes in salinity at the surface resulting from the southward transport of freshwater coming from the northern rivers. Concentrations of chlorophyll alpha and total suspended matter span more than two orders of magnitude. The bio-optical characteristics of the measurement site pertain to both Case-I (about 64%) and Case-II (about 36%) waters, based on a relationship between the beam attenuation coefficient at 660nm and the chlorophyll alpha concentration. Empirical algorithms relating in-water remote sensing reflectance ratios and optical components or properties of interest (chlorophyll alpha, total suspended matter, and the diffuse attenuation coefficient) are presented.Hooker, Stanford B.

For over 40 years, satellites have been orbiting the Earth quietly monitoring the state of our planet. Unseen by most of us, they are providing information on the many changes taking place, from movements in the land and volcanic eruptions, to human-caused changes such as the growth of cities, deforestation and the spread of pollutants in the atmosphere and oceans. Led by four editors with support from a production team at NASA Goddard Space Flight Center, many of the world's top remote sensing scientists showcase some spectacular and beautiful satellite imagery along with informed essays on the science behind these images and the implications of what is shown. This is a stunningly attractive and informative book for anyone interested in environmental issues and the beauty of our home planet, providing inspiration for students, teachers, environmentalists and the general public alike.
