DTSGUI is a USGS software tool to import, manage, parse/cull, georeference, analyze and visualize fiber-optic distributed temperature sensor data.

An R groundwater-data processing utility for manipulating, veracity checking, and converting an 'infoGW' object to the 'GWmaster' object for the visGWDB software with demonstration for the Mississippi River Valley alluvial aquifer

The multiple Grubbs-Beck low-outlier test on positively distributed data is supported along, and utilities provided for noninterpretive U.S. Geological Survey (USGS) annual peak-streamflow data processing.

This program is used to calculate anharmonic p- and s-wave velocity and density for zero-porosity mineral aggregates. It is based on the work of Hacker and Abers (2004, updated in 2016) with additional minerals and optimized for related work. Running the code in either MATLAB or Python requires a mineral physics database, MineralPhysicsDatabase.nc (https://doi.org/10.5066/P9HN170G)...

The Cyanobacteria Assessment Network (CyAN) is a multi-agency project to develop remote sensing technology using satellite data to provide early warnings for cyanobacteria and algal blooms in U.S. lakes and reservoirs. To support remote sensing efforts by CyAN, validating satellite imagery is critical to developing early warning indicators for cyanobacteria and algae blooms. This open...

RSPARROW, now available on the USGS GitLab repository, provides the first open-source version of the USGS SPARROW water-quality model

A continually increasing number of high-quality digital strong-motion records from stations of the National Strong Motion Project (NSMP) of the U.S. Geological Survey (USGS), as well as data from regional seismic networks within the U.S., called for automated processing of strong-motion records with human review limited to selected significant or flagged records. This PRISM (Processing...

The software "popcluster" constructs hierarchically nested groupings of similar habitats associated with field surveys while considering biological structure/connectedness (movements between habitats). This approach can support mobile species with high site fidelity where monitoring during surveys occurs on birthing grounds, breeding grounds, or stopovers/seasonal habitat for migratory...

The goal of this project is to update, restructure, and consolidate existing USGS ground-motion processing software to incorporate recent advances from researchers at the USGS, PEER, and others. It will standardize tools for multiple USGS ground-motion products and enable scientists within the USGS and the external community to develop and expand ground-motion datasets used in many...

A repository for USGS ISO metadata content specifications. Content specifications define documentation requirements for various USGS data and software products. These specs are used to guide authors in developing robust standardized metadata using the ISO 19115 suite of metadata standards. The repository is used for development, testing and implementation of content spec modules. It...

Tools for traversing and working with National Hydrography Dataset Plus (NHDPlus) data. All methods implemented in 'nhdplusTools' are available in the NHDPlus documentation available from the US Environmental Protection Agency https://www.epa.gov/waterdata/basic-information.

GCLAS is a program designed to compute daily and annual loadings of constituents transported in rivers.
