Heterogeneity of Sedimentary Aquifers: effect on microbial dynamics at successive spatial scales as revealed by geophysical imaging: Final report to the Department of Energy on Award DE-FG02-9ER62478

摘要

This report describes the geological component of the interdisciplinary study of the experimental aquifer at Oyster, Virginia, by the NABIR program, Department of Energy (Natural and Accelerated Bioremediation Research), between 1997 and 2003, as conducted by the Sediment dynamics group of Old Dominion University. The Geological component of the Oyster study was designed to (1) predict patterns of physical heterogeneity in sedimentary aquifers that control groundwater flow by application of geological first principles, (2) determine the geophysical imaging signatures of these patterns, and (3) relate patterns of physical heterogeneity thus sampled to observed microbial populations. The geological study began in 1997 at the North Oyster site, but in 2002, moved to the South Oyster site.
