  • Keeping a commitment to the environment

    The Memphis District has a team of scientific divers experienced in qualitative and quantitative freshwater mussel surveys and aquatic habitat investigations. The team conducts surveys in large and small rivers and various aquatic habitats throughout the country. On July 7, the dive team performed a survey in Iron Mines Creek in Marked Tree, Ark. as part of an environmental impact assessment for a creek cleanout project.

  • Army Corps of Engineers reports an increase in adult drowning at its lake and river projects this summer

    The U.S. Army Corps of Engineers announced today that more than 30 people lost their lives to drowning in June at lake and river projects the agency manages. The June statistics represent a 47 percent increase in drownings over the same time period last year. USACE also reported that nearly all the drowning victims were adult males between the ages of 18 and 85 and were not wearing a life jacket at the time of the drowning.

  • PUBLICATION NOTICE: Spatiotemporally coherent tensor decompositions for the analysis of trajectory data By Trevor Ruiz and Charlotte Ellison

    Abstract: Location acquisition technologies such as global positioning systems (GPS) sensors or telemetry devices generate abundant spatiotemporal measurements of movement of people, animals, and vehicles. The resultant data represent trajectories-paths in space and time traversed by moving objects- and can often be merged with additional information about the entities in motion from connected or external data sources (Zheng 2015). New data analysis frameworks may be able to uncover patterns of human behavior from the fused trajectory and contextual i information. This data and new insights gained from novel analysis tools are p potentially of great interest to the Army and the geospatial community.

  • PUBLICATION NOTICE: Influences of U Sources and Forms on Its Bioaccumulation in Indian Mustard and Sunflower

    Abstract: Anthropogenic activities, such as ore mining and processing, nuclear power generation, and weapon tests, have generated uranium (U) contamination to soils and waters. The mobility and bioavailability of U are influenced by its sources, speciation, and plant species. Phytoremediation has emerged as an environmentally friendly, cost-effective green technology to remediate radioisotope-and metalcontaminated soils. The main objective of this study was to explore the feasibility using sunflower (Helianthus annuus) and Indian mustard (Brassica juncea) in cleaning up soils with UO2, UO3, and UO2(NO3)2. Uranium was found to be bioaccumulated in plant roots more than plant shoots. Uranium uptake by both plant species was significantly higher from the UO3- and uranyl-contaminated soils than from UO2- contaminated soils. UO3- and UO2(NO3)2-contaminated soils showed higher exchangeable, weak acid extractable, and labile U than the UO2-contaminated soils. After a growing season, three U forms decreased as redistribution/transformation of U resulted in U species with lower extractability. This study indicates the importance of U speciation in soil with regard to the potential use of sunflower and Indian mustard for phytoremediation of U-contaminated soils.
