|
 | 3-Nitro-l,2,4-triazol-5-onc (NTO) is an explosive developed at the Los Alamos National Laboratory in 1984. The thermal decomposition characteristics of NTO, including calculated detonation velocity and pressure, are similar to those of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX); however, NTO is less sensitive and more stable. Little or no open literature is available about the environmental toxicity of NTO and understanding of potential ecological impacts of its accidental release into aquatic ecosystems is necessary prior ... |

| The long-term goal of this research is to advance the knowledge necessary to develop wide-swath laser-based underwater imaging systems that provide greater sensitivity over longer ranges than existing systems. In addition, since existing imaging systems are physically incompatible with small form-factor Autonomous Underwater Vehicles (AUVs), this effort concentrated on methods specifically aimed at size reduction while improving or maintaining image performance. The primary application for these systems is in imaging ... |

| The United States Marine Corps established a new program, the 66mm Smoke Screening IR, Vehicle Launched MK1 MODO, for the redesign of the previously fielded 66mm M76 grenade. Although the M76 grenades provided effective screening in the visual and thermal IR wavebands, there were considerable safety, health, and environmental concerns associated with the manufacturing and operation of the grenades. Red Phosphorous (RP) has been widely used in many screening applications ... |

|
| The axiom that knowledge is power applies directly to the problems experienced by the U.S. Navy in encountering dolphins and whales. If the Navy had more knowledge of the what, where, when and why of marine mammals in a given body of water, encounters between Naval vessels and marine mammals could be reduced or avoided all together. However, the cost of negative encounters is disproportionately high in terms of negative ... |

|
| One of the responsibilities of the U.S. military is to operate munitions test and live-fire training ranges. As a result of this testing and training, many explosives and their degradation products persist in the environment. Ecosystem management by military installations can be met only by providing the tools necessary to actively manage watersheds. Water quality and related aquatic ecosystems are major end-points and are insufficiently understood components of natural resource ... |

|
| BACKGROUND: Aquatic system restoration often involves establishment or reestablishment of native aquatic plant communities. The role of plants in aquatic systems is significant: in addition to providing valuable fish and wildlife habitat (Dibble et al. 1996), aquatic plants can improve water clarity and quality (James and Barko 1990), reduce rates of shoreline erosion and sediment resuspension (James and Barko 1995), and help prevent spread of nuisance exotic plant species (Smart ... |

| Man-made reservoirs initially lack aquatic plants, and their operation for flood protection or water supply may result in extreme water level fluctuations that hinder natural establishment. In many cases natural establishment could take decades or even longer. In the interim these reservoirs provide relatively poor aquatic habitat and water quality. Unvegetated aquatic ecosystems are also at risk of invasion by problematic, non indigenous species. These unvegetated man-made systems would benefit ... |

|
| In aquatic ecosystems, algae are the primary producers and the base of the food web. To date, there has been little research on the role of benthic algae (periphyton) in the bioaccumulation of mercury (Hg) in riverine systems -- a key step of the process of bioaccumulation from the physical environment (water and sediments) to higher aquatic organisms (invertebrates, fish, and others). Periphyton has been shown to have an important ... |

| This technical note documents the assessment of potential water quality improvements and economic impacts associated with streambank stabilization and phosphorus retention. Phosphorus (P) comes from both point sources (e.g., sewage effluents and industrial discharge) and nonpoint sources (e.g., urban, agricultural, and forest runoff). Measures to control point source pollution (e.g., constraints on P-based inputs) were implemented with the 1972 U.S. Clean Water Act. Recent environmental management efforts have focused on ... |

| A survey of macroinvertebrates and their habitat was conducted in Luxapalila Creek soon after completion of flood control measures in the lower reach near Columbus, MS, 1998-2000. The results of this study were compared with a similar preconstruction survey conducted in 1987-1989. There was no evidence of adverse effects of construction on the benthic macroinvertebrate community. Recently channelized, unchannelized, and historically channelized portions of the stream differed somewhat in geomorphological ... |

| Stream restoration projects usually involve some modification to the channel or the banks. Designers of stabilization or restoration projects must ensure that the materials placed within the channel or on the banks will be stable for the full range of conditions expected during the design life of the project. Unfortunately, techniques to characterize stability thresholds are limited. Theoretical approaches do not exist and empirical data mainly consist of velocity limits, ... |

| Riparian zones occur throughout the United States as long strips of vegetation adjacent to streams, rivers, lakes, reservoirs, and other inland aquatic systems that affect or are affected by the presence of water. This vegetation contributes to unique ecosystems that perform a large variety of ecological functions. Unfortunately, considerable variation is associated with riparian terminology, similar to problems associated with wetlands terminology (Mitsch and Gosselink 1993). This can lead to ... |

| Ears are the bell weathers of pressure induced damage. Equally important, they are a crucial sensory system for marine mammals. Although marine mammal ears are similar to those of land mammals, there are also sufficient differences to prevent extrapolation of damage criteria from air adapted ears to marine systems. Therefore, understanding how intense pressures affect marine mammal ears is required in order to properly mitigate effects from man made impulse ... |

| Many aquatic invertebrate animals, including bivalves, are intolerant of even relatively modest increases in the ambient concentration of carbon dioxide (CO2). This intolerance is based on the chemical reaction of CO with water to form carbonic acid. Carbon dioxide has the potential to be used as a molluscicide for zebra mussel control because these organisms, like almost all bivalves, do not contain the oxygen-carrying proteins to ... |

| Fingernail clams (Sphaeriidae) are important food sources for fish and migrating waterfowl in the Upper Mississippi River (UMR). Historically, fingernail clam densities ranged from 1,000 - 10,000 m-2 (per square meter) in parts of the UMR. Recent studies indicate that fingernail clam populations may be on the decline. In 1975, lower Pool 8 had fingernail clam densities as high as 2,400 m-2. More recent sampling (yearly since 1992) conducted by ... |

| After the open-water disposal of dredged sediments was observed to have deleterious effects on the aquatic ecosystems of the Great Lakes, an alternative was sought to reduce the exposure of lake biota to dredged material contaminants. In 1970, the Rivers and Harbors Flood Control Act authorized the U.S. Army Corps of Engineers to construct CDFs to contain material dredged from contaminated Great Lakes harbors and ... |

| Water depth is an important feature of aquatic systems. On the Upper Mississippi River System (UMRS), water depth data is important for describing the physical template of the system and monitoring changes in this template caused by sedimentation. Although limited point or transect sampling of water depth can provide valuable information on habitat character in the UMRS as a whole, the generation of bathymetric maps is critical for conducting spatial ... |

| The data presented in this report demonstrate the utility of the SPMD technique for sequestering environmentally realistic concentrations of OC pesticide residues (i.e., 1 ng/L, 10 ng/L, and 100 ng/L) at water temperatures ranging from I 00C to 260C. The data are indicative of concentration independent sampling rates for the 23 OC pesticides employed in this research. As predicted by both thermodynamic and kinetic considerations, the sampling rates for all ... |
