The Mars Global Digital Dune Database (MGD3) is an online repository that has catalogued dune fields larger than 1 km2 located between latitudes 90° N. and 90° S. The work presented here expands upon previous MGD3 open-file reports, with a new emphasis upon characterizing dune fields through composition, stability, and thermal inertia. Included in this latest addition is a detailed compositional analysis and the associated observational data from Mars Global Surveyor (MGS) Thermal Emission Spectrometer (TES) for dune fields 300 km2 or larger; a near-global dune stability assessment; Mars Odyssey (MO1) Thermal Emission Imaging System (THEMIS) apparent thermal inertia values; and vertical near-surface thermophysical...

A study conducted by the U.S. Geological Survey, in cooperation with the New Jersey Pinelands Commission and Montclair State University, was designed to compare pesticide concentrations and the presence and prevalence of amphibian pathogens between natural ponds and two types of created wetlands, excavated ponds and stormwater basins, throughout the New Jersey Pinelands. The study described herein is part of a larger study by the New Jersey Pinelands Commission designed to compare the functional equivalency of natural and created wetlands throughout the New Jersey Pinelands. Sites were selected on the basis of land-use classifications within a 500-meter radius around each wetland from a pool of natural ponds, excavated...

This report contains data from the survey of manmade nonagricultural volatile and semivolatile organic chemicals in surface water in the upper Illinois River basin from May 1988 through March l990. In addition to the data, sampling methods and quality-assurance procedures are described. The survey was part of the upper Illinois River basin pilot project of the National Water-Quality Assessment program conducted by the U.S. Geological Survey. The organic chemicals analyzed from the water samples were those expected to be associated primarily with effluent from point sources in urban areas. A low-flow synoptic investigation of 52 volatile and 54 semivolatile organic chemicals was conducted at 31 sites in July 1988....

A 5,670-sq m wet detention pond was monitored by the U.S. Geological Survey to determine its effect on the water quality of urban runoff. The pond has a drainage area of 0.96-sq km, composed primarily of single-family residential land use. Event-mean concentrations (EMC) were determined from samples collected for sediment, nutrients, and selected metals at the pond's inflow and outflow sites. EMC samples were collected for 64 runoff events during the study period from February 1987 to April 1988. Storm precipitation ranged from 1 to 51 mm during these events. Inflow and outflow EMC and constituent loads were compared to determine the trap efficiency of the pond. Trap efficiency varied considerably among water-quality...

This report summarizes the 1991 water-use reporting through the Conservation District Office in Lincoln County, Arkansas. The number of withdrawal registrations for Lincoln County was 1,167 (868 groundwater and 299 surface water). Water with- drawals reported during the registration process total 3.88 Mgal/d (3.88 Mgal/d groundwater and none from surface water) for agriculture and 114.31 Mgal/d (98.59 Mgal/d groundwater and 15.72 Mgal/d surface water) for irrigation. The registration reports for 1991 indicate that this water was applied to 81,477 acres of land to irrigate rice, corn, soybeans, milo, cotton and vegetables as well as for the agricultural use of animal aquaculture.

This report summarizes the 1991 water-use reporting through the Conservation District Office in Cross County, Arkansas. The number of withdrawal registrations for Cross County was 2,506 (2,314 groundwater and 192 surface water). Water withdrawals reported during the registration process total 2.01 Mgal/d (1.85 Mgal/d groundwater and 0.16 Mgal/d surface water) for agriculture and 404.04 Mgal/d (377.08 Mgal/d groundwater and 26.96 Mgal/d surface water) for irrigation. The registration reports for 1991 indicate that this water was applied to 218,152 acres of land to irrigate rice, sorghum, corn, soybeans, milo, cash grains, cotton, hay, and vegetables as well as for the agricultural use of animal aquaculture and ducks.
