This report documents a hydrodynamic field investigation conducted to provide data for the development of a three-dimensional hydrodynamic model of the San Juan Bay and Estuary System in Puerto Rico. Representative results of a field investigation of the San Juan Bay Estuary System conducted from 22 June to 19 August 1995 are presented. They include short-term measurements of current speed and direction, salinity profiles, water samples, and water-level fluctuations. Long-term measurements include water-level monitoring, salinity measurements, and fixed-depth current speed, direction, and salinity. Field investigation equipment and methods used to collect the data are described, representative results of the data reduction methods are presented, and results of the investigation are summarized.

Coastal Lagoons: Ecosystem Processes and Modeling for Sustainable Use and Development describes the concepts, models, and data needed to design and implement management programs for long-term sustainability of coastal lagoons. Based on a project conducted under the auspices of NATO-CCMS, the book provides information and methodologies essential for
