Standard atomic weights of the elements 2021 (IUPAC Technical Report)
Following the reviews of atomic-weight determinations and other cognate data in 2015, 2017, 2019 and 2021, the IUPAC (International Union of Pure and Applied Chemistry) Commission on Isotopic Abundances and Atomic Weights (CIAAW) reports changes of standard atomic weights. The symbol A r°(E) was selected for standard atomic weight of an element to distinguish it from the atomic weight of an elemen

Surface parameters and bedrock properties covary across a mountainous watershed: Insights from machine learning and geophysics
Bedrock property quantification is critical for predicting the hydrological response of watersheds to climate disturbances. Estimating bedrock hydraulic properties over watershed scales is inherently difficult, particularly in fracture-dominated regions. Our analysis tests the covariability of above- and belowground features on a watershed scale, by linking borehole geophysical data, near-surface

Determination of optimal set of spatio-temporal features for predicting burn probability in the state of California, USA
Wildfires play a critical role in determining ecosystem structure and function and pose serious risks to human life, property and ecosystem services. Burn probability (BP) models the likelihood that a location could burn. Simulation models are typically used to predict BP but are computationally intensive. Machine learning (ML) pipelines can predict BP and reduce computational intensity. In this w

Management goals for conserving White Sturgeon in the Sacramento-San Joaquin River basin
Management objectives for long-lived species are difficult to define because many taxa have delayed maturity and variable recruitment. White Sturgeon Acipenser transmontanus is an example of a species with a complex life history that complicates long-term status monitoring and establishment of management objectives. Historically, White Sturgeon in the Sacramento–San Joaquin River basin have been m

Refining sources of polychlorinated biphenyls in the Back River watershed, Baltimore, Maryland, 2018–2020
Older urban landscapes present unique and complex stressors to urban streams and their habitats through the introduction of legacy and emerging toxic contaminants. Contaminant sources are often associated with various developed land uses such as older residential areas, active and former industrial sites, contaminated sites, and effluents from municipal wastewater treatment plant discharges. These

Nevada and Landsat
Nevada’s geography is colorful—and contradictory. As one of the most mountainous States, Nevada shares the country’s second-deepest lake, Lake Tahoe, with neighboring California. It is also the driest State and largely covered by desert. Northern Nevada has long, cold winters, whereas the south has long, hot summers. It is the seventh-largest State, but it ranks in the bottom one-half of States fo

Wyoming and Landsat
Wyoming has the smallest population of any State—fewer than 600,000 people—but an abundance of wildlife. The largest number of pronghorn (Antilocapra americana), often called antelope, and the biggest public bison (Bison bison) herd in the United States live in Wyoming, which also hosts elk (Cervus elaphus), moose (Alces americanus), bighorn sheep (Ovis canadensis), black bears (Ursus americanus)

Monitoring fish abundance and behavior, using multi-beam acoustic imaging sonar, at a Selective Water Withdrawal structure in Lake Billy Chinook, Deschutes River, Oregon, 2020
Collection of juvenile salmonids at Round Butte Dam is a critical part of the effort to enhance populations of anadromous fish species in the upper Deschutes River because fish that are not collected at the dam may either incur increased mortality during dam passage or remain landlocked and lost to the anadromous fish population. Adaptive resolution imaging sonar systems were used to assess the be

Water priorities for the Nation—U.S. Geological Survey Integrated Water Prediction science program
The U.S. Geological Survey Integrated Water Prediction science program focuses on the development of advanced models for forecasting water use and other components of the water cycle along with water quality attributes such as temperature, water constituents, and ecological conditions. The program also is developing the cyberinfrastructure required to implement national and local-scale models to b

Risk assessment for bull trout introduction into Sullivan Lake and Harvey Creek, northeastern Washington
The Kalispel Tribe of Indians (KT), U. S. Fish and Wildlife Service, and Washington Department of Fish and Wildlife are engaged in conservation of bull trout (Salvelinus confluentus) in the Lake Pend Oreille (LPO) Core Area. The LPO is a complex habitat core area which falls within three states (Montana, Idaho, and Washington) and a tribal entity. As part of the conservation process, KT worked in

Global groundwater solute composition and concentrations
Informed analysis of policies related to food security, global climate change, wetland ecology, environmental nutrient flux, element cycling, groundwater weathering, continental denudation, human health, etc. depends to a large extent on quantitative estimates of solute mass fluxes into and out of all global element pools including the enigmatic global aquifer systems. Herein for the first time, w

Alaskan Yelloweye Rockfish fecundity revealed through an automated egg count and digital imagery method
Spawning stock biomass (SSB) is often used as an index for reproductive potential (RP) in fisheries stock assessments. This method assumes that mature female biomass is proportional to total egg production and implies that (1) the fecundity–length relationship follows a cubic function or (2) relative fecundity is constant. For many marine fishes, adequate fecundity estimates to evaluate these rela
