Naled and dichlorvos in water and aquatic organisms from a canal and rice fields near Sacramento, California Naled and dichlorvos in water and aquatic organisms from a canal and rice fields near Sacramento, California
Ultra-low volumes of naled are applied by aircraft over rice fields and canals to reduce adult mosquito populations near Sacramento, California. Each summer, the pesticide is applied approximately 7-10 times between July and October. Naled and its major degradate (dichlorvos) were quantified in water, biofilm, and invertebrates following aerial applications. In 2020, samples were...
Pollen data from seven lakes in the Klamath Mountains, California: a case study for paleoecological reconstruction Pollen data from seven lakes in the Klamath Mountains, California: a case study for paleoecological reconstruction
The dataset include raw pollen counts, age model data, and pollen accumulation rates with uncertainty estimates for seven lake sites in the Klamath Mountains, California, USA. The raw pollen counts reflect the relative abundance of major taxa from the vegetation surrounding each lake site (n=7) at 5 different time periods. The age model data provides a Bayesian-based estimate of the...
Chemical alteration index values and rare earth element data and expected ranges for regolith overlying the Stewartsville pluton, Virginia Chemical alteration index values and rare earth element data and expected ranges for regolith overlying the Stewartsville pluton, Virginia
This dataset contains whole major element geochemical data used to calculate values of the chemical alteration index (CIA), data for Nd, Sm, Y, and total REE and expected ranges for total REEY for samples of regolith overlying the Stewartsville pluton, Virginia. The southeastern United States was first identified as prospective for regolith-hosted REE deposits based on the recognition...
Airborne Magnetic Survey, Michigan Upper Peninsula Area, 2008 Airborne Magnetic Survey, Michigan Upper Peninsula Area, 2008
This publication provides digital flight line data for a high-resolution magnetic survey over an area of the west-central Upper Peninsula of Michigan. The survey was flown in 2008 by Aeroquest under contract to Kennecott Eagle Minerals Company using a fixed-wing aircraft with a magnetometer mounted in a tail stinger. The USGS has obtained this 66,074 line km subset of the survey dataset...
Mapping irregularly flooded wetlands, high marsh, and salt pannes/flats along the northern Gulf of Mexico coast (ver. 2.0, June 2023) Mapping irregularly flooded wetlands, high marsh, and salt pannes/flats along the northern Gulf of Mexico coast (ver. 2.0, June 2023)
This data release includes geospatial data for irregularly flooded wetlands and high marsh and salt pannes/flats along the northern Gulf of Mexico coast from Texas to Florida. Specifically, this release includes seven products: (1) a map highlighting the continuous probability that an area is an irregularly flooded wetland; (2) a map of irregularly flooded wetland probability...
