This presentation is divided into two main parts. The scientifc sections include historical information on the area; shipboard, field, and remote-sensing studies; and a comprehensive sediment database with geological and chemical discussions of the region. The multimedia and resources sections include geographic information system (GIS) tools and data, a video demonstrating vibracore sampling techniques in Lake Pontchartrain, and abstracts from four Basics of the Basin symposia.
