Kiloyear cycles of carbonate and Mg-silicate replacement at Von Damm hydrothermal vent field Kiloyear cycles of carbonate and Mg-silicate replacement at Von Damm hydrothermal vent field
The Von Damm vent field (VDVF) on the Mid-Cayman Rise in the Caribbean Sea is unique among modern hydrothermal systems in that the chimneys and mounds are almost entirely composed of talc. We analyzed samples collected in 2020 and report that in addition to disordered talc of variable crystallinity, carbonates are a major class of mineral at VDVF. The carbonate minerals include aragonite...

Negative growth in body mass of trout and salmon in a small stream network Negative growth in body mass of trout and salmon in a small stream network
In species inhabiting stressful environments, some individuals experience negative growth in body mass during their lives, potentially influencing survival, reproduction, populations, and ecosystems. Using data from a long-term (1997–2015) study of brook trout (Salvelinus fontinalis), brown trout (Salmo trutta), and juvenile Atlantic salmon (Salmo salar) in Massachusetts, USA, we...

Sentinel imagery detects the presence of live trees following large wildfires in California Sentinel imagery detects the presence of live trees following large wildfires in California
Identifying live tree presence following wildfire is important for burn damage assessments and decision making, as these trees serve as seed sources for recovery. Satellite-based remote sensing offers an efficient means to assess burn severity with products representing vegetation greenness and char/ash presence and their change from pre- to post-fire imagery. While effective at...

Flood of July 2023 in Vermont Flood of July 2023 in Vermont
A major storm caused catastrophic flooding in many parts of Vermont on July 9–12, 2023, resulting in millions of dollars in damages. The high amount of rainfall caused several rivers to peak at record levels, in some cases exceeding records set during Tropical Storm Irene in 2011. The U.S. Geological Survey, in cooperation with the Federal Emergency Management Agency, collected and...

Peak streamflow trends in Montana and northern Wyoming and their relation to changes in climate, water years 1921–2020 Peak streamflow trends in Montana and northern Wyoming and their relation to changes in climate, water years 1921–2020
Frequency analysis on annual peak streamflow (hereinafter, peak flow) is essential to water-resources management applications, including critical structure design (for example, bridges and culverts) and floodplain mapping. Nonstationarity is a statistical property of a peak-flow series such that the distributional properties (the mean, variance, or skew) change either gradually...

Exposure of infants to antibiotics via cord blood, breast milk, and formula: A review on exposure level, temporal variation, and risk assessment Exposure of infants to antibiotics via cord blood, breast milk, and formula: A review on exposure level, temporal variation, and risk assessment
The pervasive use of antibiotics across various sectors, including agriculture, medicine, and aquaculture, has led to a notable increase in environmental antibiotic residues. This phenomenon has raised significant public concern regarding the potential health risks antibiotics may pose, particularly to vulnerable populations such as infants. However, the conceptualization of exposure...

Effects of riparian forest thinning on resident salmonid fishes in coastal northern California catchments Effects of riparian forest thinning on resident salmonid fishes in coastal northern California catchments
Resource managers are interested in whether thinning second-growth forests may be a viable restoration strategy for stream and riparian habitats, but may be concerned about the potential impacts that increases in stream temperature associated with riparian thinning treatments may have on cold-water salmonid fishes.We evaluated the effects of riparian forest thinning on resident...

Cave records reveal recent origin of North America’s deepest canyon Cave records reveal recent origin of North America’s deepest canyon
We explore how and when Hells Canyon, North America’s deepest river gorge (~2,400 m deep), formed, addressing these fundamental questions first posed by W. Lindgren [The Gold Belt of the Blue Mountains of Oregon (1901)]. Existing hypotheses about the canyon’s formation and timing of incision remain speculative due to a lack of direct constraints and geomorphic analysis in the canyon...

Diagnostic success—A quick guide to quality carcass submissions for diagnostic services Diagnostic success—A quick guide to quality carcass submissions for diagnostic services
The U.S. Geological Survey National Wildlife Health Center provides diagnostic services to determine causes of wildlife morbidity and mortality events to State, Federal, and Tribal partners. To accomplish this, we rely on the timely collection and evaluation of submitted carcasses and the epidemiologic information relayed from personnel in the field. Our current submission criteria can...

Infrasonic directivity of monopole, dipole, and bipole ground-surface reflected sources Infrasonic directivity of monopole, dipole, and bipole ground-surface reflected sources
Infrasound (acoustic waves below 20 Hz) can be used to detect, locate and quantify activity in the atmosphere such as volcanic eruptions and anthropogenic explosions. Attempts to quantify volcanic eruption parameters such as exit velocity, plume height and mass flow rate using infrasound data depend strongly on assumptions of the acoustic source type. Infrasonic sources may produce...

Medium resolution lunar topography: An updated view of the lunar surface from stereophotogrammetrically derived DTMs Medium resolution lunar topography: An updated view of the lunar surface from stereophotogrammetrically derived DTMs
Digital Terrain Models (DTMs) are essential for lunar exploration, supporting critical applications such as landing site selection,mission planning, and in situ resource utilization. This study presents a comprehensive reprocessing of the Kaguya Terrain Camera (TC) dataset using the NASA Ames Steropipeline to generate over 130,000 medium-resolution DTMs with nearly global lunar coverage...
