bbsAssistant: An R package for downloading and handling data and information from the North American Breeding Bird Survey.
This R package contains functions for downloading and munging data from the North American Breeding Bird Survey (BBS) via FTP (Pardieck et al. 2018; J. R. Sauer et al. 2017). This package was created to allow the user to bulk-download the BBS point count and related (e.g., route-level conditions) via FTP, and to quickly subset the data by taxonomic classifications and/or geographical locations. Th
FLASH-R: Flow-Log Analysis of Single Holes
FLASH-R (Flow-Log Analysis of Single Holes) is an R app for the analysis of borehole vertical flow logs to estimate fracture (or layer) transmissivities and far-field hydraulic heads.
TracerLPM
An Excel® Workbook for Interpreting Groundwater Age Distributions from Environmental Tracer Data
Electromagnetic Transfer Function File Conversion Utilities (EMTF FCU)
Magnetotelluric impedances and other similar transfer functions are important for geophysical interpretation and for space weather hazards. I helped develop and continue to curate a database known as IRIS EMTF, http://ds.iris.edu/spud/emtf which uses something called EMTF XML format for storing the data. EMTF FCU v4.1 software consists of a set of freely available format conversion tools that can
Quality control tools for seismic catalogs (qc_report and qc_multi)
Generate plots and statistics for single earthquake catalogs and for catalog to catalog comparisons.
Floodplain and Channel Evaluation Tool (FACET)
The Floodplain and Evaluation Tool (FACET) is an open-source python tool that maps the floodplain extent and derives reach-scale summaries of stream and floodplain geomorphic measurements from high-resolution digital elevation models (DEMs).
Floodplain and Channel Evaluation Tool: FACET
FACET is a Python tool that uses open source modules to map the floodplain extent and derive reach-scale summaries of stream and floodplain geomorphic measurements from high-resolution digital elevation models (DEMs). Geomorphic measurements include channel width, stream bank height, floodplain width, and stream slope. FACET allows the user to hydrologically condition the DEM, generate the stream
Wild horse aerial double observer survey analysis R script
This R file estimates horse abundance by analyzing data from simultaneous double-observer aerial surveys. The code follows analytical procedures established by Dr. Bruce Lubow, the statistician contracted for many years by Bureau of Land Management (BLM). Field data collection techniques are described in the Standard Operating Procedures (SOPs), which is a separate document.

DTSGUI
DTSGUI is a USGS software tool to import, manage, parse/cull, georeference, analyze and visualize fiber-optic distributed temperature sensor data.
infoGW2visGWDB, Conversion of an infoGW object to a GWmaster object compatible with the visGWDB software
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
MGBT, Multiple Grubbs-Beck low-outlier test
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.
MinVel
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). Combined with
