Trackline map of all boomer data collected during USGS Cruise 01RCE02. These data were collected in Louisiana river deltas in April and May of 2001. This map is in geographic projection and was created at a scale of 1:1,200,000 using ESRI's GIS software ArcView 3.2. The image was exported to Adobe Illustrator for further editing and saved for the web in JPEG format. The USGS is not the originator of all layers used in creating this map. The rivers layer is a LOSCO (Louisiana Oil Spill Coordinator's Office) dataset derived from ESRI/GDT (Geographic Data Technology, Inc.) data that were in turn derived from Bureau of the Census TIGER/Line files. The waterbodies layer is also a LOSCO dataset derived from ESRI/GDT data.
