During the fall of 200, archaeologists from Panamerican Consultants, Inc (PCI) conducted remote-sensing investigations in the Dog River, Mobile County, Alabama, as part of the U.S. Army Corps of Engineers, Mobile District's project entitled Underwater Remote Sensing Survey, Dog River, Mobile County, Alabama. Project plans call for the dredging of an area 100 feet wide in the center of the navigation channel. The project area consists of several corridors 100 feet in width and ranging in length from 500 feet to 8000 feet. The remote-sensing survey located seven anomalies in the project area. Of these seven anomalies, four did not meet the accepted criteria of 50 gamma strength over 80 feet duration. Two more met the criteria, but were close enough in proximity that they were treated as a single anomaly cluster rather than distinct individual anomalies. Finally, one anomaly had characteristics representative of a pipeline, but a historical records search revealed no known pipeline in the area of the anomaly. This anomaly and the aforementioned anomaly cluster are both recommended for further investigation via probing or diver inspection.

Remote sensing stands as the defining technology in our ability to monitor coral reefs, as well as their biophysical properties and associated processes, at regional to global scales. With overwhelming evidence that much of Earth’s reefs are in decline, our need for large-scale, repeatable assessments of reefs has never been so great. Fortunately, the last two decades have seen a rapid expansion in the ability for remote sensing to map and monitor the coral reef ecosystem, its overlying water column, and surrounding environment. Remote sensing is now a fundamental tool for the mapping, monitoring and management of coral reef ecosystems. Remote sensing offers repeatable, quantitative assessments of habitat and environmental characteristics over spatially extensive areas. As the multi-disciplinary field of coral reef remote sensing continues to mature, results demonstrate that the techniques and capabilities continue to improve. New developments allow reef assessments and mapping to be performed with higher accuracy, across greater spatial areas, and with greater temporal frequency. The increased level of information that remote sensing now makes available also allows more complex scientific questions to be addressed. As defined for this book, remote sensing includes the vast array of geospatial data collected from land, water, ship, airborne and satellite platforms. The book is organized by technology, including: visible and infrared sensing using photographic, multispectral and hyperspectral instruments; active sensing using light detection and ranging (LiDAR); acoustic sensing using ship, autonomous underwater vehicle (AUV) and in-water platforms; and thermal and radar instruments. Emphasis and Audience This book serves multiple roles. It offers an overview of the current state-of-the-art technologies for reef mapping, provides detailed technical information for coral reef remote sensing specialists, imparts insight on the scientific questions that can be tackled using this technology, and also includes a foundation for those new to reef remote sensing. The individual sections of the book include introductory overviews of four main types of remotely sensed data used to study coral reefs, followed by specific examples demonstrating practical applications of the different technologies being discussed. Guidelines for selecting the most appropriate sensor for particular applications are provided, including an overview of how to utilize remote sensing data as an effective tool in science and management. The text is richly illustrated with examples of each sensing technology applied to a range of scientific, monitoring and management questions in reefs around the world. As such, the book is broadly accessible to a general audience, as well as students, managers, remote sensing specialists and anyone else working with coral reef ecosystems.

Sponsored by the Committee on Advanced Data Collection and Management Systems of ASCE. This casebook offers examples of civil engineering practices in the acquisition and use of data obtained with advanced aerial and ground-based remote collection systems. The first section deals with remote sensing imagery and data utilization and applications to water resources site and route selection, environmental inventory, land use, and facilities. Specific applications include photobathymetry, landsat imagery, and energy-loss surveys using thermalØinfrared technology. Noncontact and contact data collection and data relay systems are reviewed, along with surface temperature mapping, photogeodesy and hydrologic telemetry from remote areas. The final section presents discussions on data processing and its applications to both data organization and information extension.
