Data Releases

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Global gridded dataset of terrestrial biological nitrogen fixation across natural and agricultural biomes Global gridded dataset of terrestrial biological nitrogen fixation across natural and agricultural biomes

This dataset includes global rasters of terrestrial biological nitrogen fixation (BNF) rates (in kg N/ha/y) for each major N-fixing niche in natural biomes (trees, shrubs, herbs, soil, litter, dead wood, ground mosses, biocrusts, and epiphytic lichens) and agricultural biomes (legume crops, forage legumes, and rice). It also includes total natural terrestrial, total agricultural, and...

A global dataset of terrestrial biological nitrogen fixation A global dataset of terrestrial biological nitrogen fixation

This dataset includes field measurements of biological nitrogen fixation (BNF) in all major N-fixing niches across natural terrestrial biomes globally. The dataset comprises 32 variables including site location, biome type, N-fixing niche, sampling year, quantification method, BNF rate (in kg N/ha/y), the percentage of nitrogen derived from the atmosphere, N-fixer or N-fixing substrate...

California condor and black vulture Highly Pathogenic Avian Influenza vaccine trial California condor and black vulture Highly Pathogenic Avian Influenza vaccine trial

In 2023, critically endangered California condors experienced an outbreak of highly pathogenic avian influenza (HPAI). We evaluated safety, immunogenicity, vaccination strategies, and correlates of antibody response of a conditionally licensed influenza vaccine for poultry in black vultures and then California condors. These data represent the correlates of antibody response, including

Comparison of environmental DNA sampling protocols for detection of stream fishes in the Pacific Northwest, 2019 (ver. 2.0, November 2025) Comparison of environmental DNA sampling protocols for detection of stream fishes in the Pacific Northwest, 2019 (ver. 2.0, November 2025)

This dataset contains environmental DNA (eDNA) data (field, extraction, and qPCR) for rainbow trout sampling efforts conducted in the Pacific Northwest in 2019. Samples were collected using three eDNA sampling methods. Also included are qPCR data for extraction negatives, no-template controls (NTC), and standard dilutions of rainbow trout gBlock. NTC and gBlock qPCR data were used to...

Population viability assessment of native fish species in the Pacific Northwest accounting for instream conditions of water temperature and streamflow permanence Population viability assessment of native fish species in the Pacific Northwest accounting for instream conditions of water temperature and streamflow permanence

This data release contains geospatial representations of population viability analysis (PVA) of 23 species of Pacific Northwest non-salmonid fishes. The analysis evaluated long term species persistence (~100 years) based on species distribution models that combined 1) modeled climate, 2) instream conditions, and 3) presence/absence fish data based on species needs and current climate...
