fluvial-particle, U.S. Geological Survey software release fluvial-particle, U.S. Geological Survey software release
This Python package provides functions to simulate advection and dispersion of numerical particles using a lagrangian particle-tracking algorithm for 2 and 3-dimensionl hydraulic simulation results. Users may customize particle subclasses to provide custom particle classes. For example, the drift of larval fish, by creating classes to add behavior to particles. (McDonald and Nelson, 2021...
Scanned field notebooks from a USGS Benchmark Glacier: South Cascade Glacier, Washington,1957 - 2022 Scanned field notebooks from a USGS Benchmark Glacier: South Cascade Glacier, Washington,1957 - 2022
This data release is a collection of data and field notes documenting snow and ice changes on South Cascade Glacier, Washington, USA. The field records relate to glaciological research and reflect evolving interpretations of glacier mass balance, climatology, hydrology, and other glacier-related research conducted at the site between 1957 to 2022 in association with the USGS Benchmark...
Mercury, Cortisol, and Blood Biomarkers in Adult Female Northern Elephant Seals from 2011 to 2021 Mercury, Cortisol, and Blood Biomarkers in Adult Female Northern Elephant Seals from 2011 to 2021
This dataset represents 179 unique adult female northern elephant seals that were sampled between 2011 and 2021 during four different life history states (early breeding, late breeding, early molting, and late molting) at the Ano Nuevo colony in California, USA. Some individual seals were sampled multiple times, resulting in a total of 313 tissue samples. Tissue samples were collected...
Basin Characteristics and Salinity and Selenium Loads and Yields for Selected Subbasins in the Lower Gunnison River Basin, Western Colorado, 1992─2013 Basin Characteristics and Salinity and Selenium Loads and Yields for Selected Subbasins in the Lower Gunnison River Basin, Western Colorado, 1992─2013
Mitigating the effects of salinity (total dissolved solids) and selenium on water quality in the lower Gunnison River Basin (LGRB) of western Colorado is a major concern for land managers. In cooperation with the Bureau of Reclamation, the U.S. Geological Survey completed a study to develop multiple linear regression models to estimate salinity and selenium loads. The objective of the...
Manatee tracking, sighting and environmental data from the Northern Gulf of Mexico, 2013-2019 Manatee tracking, sighting and environmental data from the Northern Gulf of Mexico, 2013-2019
Data sets collected for manatee movement and habitat research in the Northern Gulf of Mexico from 2013-2019. These include manatee GPS tracking, manatee sightings, aquatic vegetation from manatee use areas, and environmental data (salinity and bathymetry at vegetation sampling sites).
Vegetation cover, ground cover, plant mortality, and species abundance across an experimental drought treatment on the Colorado Plateau from 2010-2022 Vegetation cover, ground cover, plant mortality, and species abundance across an experimental drought treatment on the Colorado Plateau from 2010-2022
These data were compiled to assess the response of vegetation and biological soil crusts to drought in a semi-arid ecosystem on the Colorado Plateau near Moab, Utah. Objective(s) of our study were to explore how vegetation cover, soil conditions, and growing season nitrogen (N) availability are impacted by multifaceted drying climate conditions using data from a long-term precipitation...
