Emperor Goose (Anser canagicus) Nest Visit, Fate, and Dispersal Distances from the Yukon-Kuskokwim Delta, Alaska, 2000-2017 Emperor Goose (Anser canagicus) Nest Visit, Fate, and Dispersal Distances from the Yukon-Kuskokwim Delta, Alaska, 2000-2017
These data are in two tables: 1) table relating to emperor goose nest visit, nest fate, and nest dispersal distances on the Yukon-Kuskokwim Delta in Alaska, 2000-2017; 2) table with means and standard deviations for posterior distributions of predicted nest-age and year specific daily nest survival probabilities for emperor geese derived from estimates reported by Thompson et al. (2023)...
Argon ages near Parker, AZ, and Needles, CA Argon ages near Parker, AZ, and Needles, CA
Reported here are argon age data for samples collected to better understand lower Colorado River corridor landscape evolution, the history of the Colorado River, and define the age of geologic units being mapped. Samples of basalts, ashes, and sand were collected in the Cactus Plain southeast of Parker, AZ, the Whipple Mountain piedmont north-northwest of Parker, AZ and washes east...
Annual burn severity mosaics for the southeastern United States (2000-2022) Annual burn severity mosaics for the southeastern United States (2000-2022)
The southeastern United States experiences frequent wild and prescribed fire activity. Mapped burn severity products in the southeastern U.S. face challenges accurately characterizing fire effects due to rapid post-fire recovery limiting observation windows, limited availability of cloud-free imagery, spectral confusion within wetland areas, and operational constraints. As mapped burn...
Water Quality and Toxic Algal Presence in Burrow Pits in Eastern Lake Pontchartrain: 2021-2023 Water Quality and Toxic Algal Presence in Burrow Pits in Eastern Lake Pontchartrain: 2021-2023
This dataset consists of sensor profile and water sample results from monitoring campaign to investigate the effects of two dredged pits in eastern Lake Pontchartrain on dissolved oxygen conditions within the water column in and surrounding the pits over a three-year period. The borrow pits were excavated to provide soil material to nourish three nearby protected marsh sites: Bayou...
Low flow water quality data for the Animas River, Arrastra Creek to Silverton, Colorado, September 2021 Low flow water quality data for the Animas River, Arrastra Creek to Silverton, Colorado, September 2021
A synoptic sampling campaign was conducted on the Animas River near Silverton, Colorado, under low-flow conditions in September 2021. The sampling campaign was designed to quantify constituent loading and identify sources of contamination along a 3.8-kilometer study reach. The study reach began approximately 170 meters upstream of Arrastra Creek and extended downstream to U.S. Geological...
