Salvinia/weevil case study: Using drones to monitor weevil propagation in Salvinia aquatics (ver. 2.0, August 2023) Salvinia/weevil case study: Using drones to monitor weevil propagation in Salvinia aquatics (ver. 2.0, August 2023)
During summer months, coastal Louisiana is plagued with floating aquatics that fill and block canals and small waterways causing trouble for boaters. This floating aquatic starts growing in the spring and dies off in late summer and early winter months. One natural predator of the Salvinia sp is the weevil that forages on the Salvinia and causes premature die-off. These weevils do exist...
Partitioning of six pyrethroid insecticides at varying salinities Partitioning of six pyrethroid insecticides at varying salinities
To determine aqueous pyrethroid partitioning across a salinity gradient 20 mL Pyrex beakers were filled with 8 mL of deionized water at varying salinities (0, 0.5, 2, 6 ppt). Salinity was adjusted using a 10 ppt stock solution (made by diluting Instant Ocean into deionized water). The water samples were spiked with pyrethroids (bifenthrin, cyhalothrin, cyfluthrin, cypermethrin...
Data for Dust deposited on snow cover in the San Juan Mountains, Colorado, 2011-2016: Compositional variability bearing on snow-melt effects Data for Dust deposited on snow cover in the San Juan Mountains, Colorado, 2011-2016: Compositional variability bearing on snow-melt effects
Light-absorbing particles in atmospheric dust deposited on snow cover (dust-on-snow, DOS) diminish albedo and accelerate the timing and rate of snow melt. Identification of these particles and their effects are relevant to snow-radiation modeling and water-resource management. Laboratory-measured reflectance of DOS samples from the San Juan Mountains (USA) were compared with DOS mass...
Airborne magnetic and radiometric survey of the southeast Mojave Desert, California and Nevada Airborne magnetic and radiometric survey of the southeast Mojave Desert, California and Nevada
A high-resolution airborne magnetic and radiometric survey of the southeast Mojave Desert, parts of California and Nevada was flown by EDCON-PRJ, Inc. from December 13, 2019 to March 21, 2020. The high-resolution fixed-wing survey was flown at a flightline spacing of 200 m, an azimuth of 70 degrees, a nominal elevation above ground of 100 m, and consists of about 17,277 line-kilometers...
