Code repository for integrated occupancy model for single-visit semi-structured and single-visit time-removal sampling surveys Code repository for integrated occupancy model for single-visit semi-structured and single-visit time-removal sampling surveys
Multi-species structured surveys following specific sampling design are powerful tools for understanding species’ distributions and trends, but are not equally well-suited for surveying all species. Combining data collected under different protocols or sampling designs has the potential to boost sample size, extend geographic and environmental coverage, and improve model estimates...
Workflow and analysis for per-and polyfluoroalkyl substances (PFAS) in water and dragonfly larvae in United States protected areas Workflow and analysis for per-and polyfluoroalkyl substances (PFAS) in water and dragonfly larvae in United States protected areas
This code release provides the workflow and analysis code for a study that addresses the prevalence of PFAS on Federally protected lands in water and dragonfly larvae. This study quantifies the prevalence of PFAS in protected areas across the US, identifies ecologically relevant PFAS mixtures, and assesses the potential drivers of PFAS concentration in an effort to better understand...
Digital Shoreline Analysis System version 6.1 Digital Shoreline Analysis System version 6.1
The Digital Shoreline Analysis System (version 6) is a stand-alone desktop application that compliments a Geographic Information System (GIS). The DSAS software requires users to input a reference baseline and compilation of shoreline positions to generate measurement transects and shoreline intersections used to calculate rate-of-change statistics. DSAS provides an automated method for
MODFLOW Version 6.7.0 MODFLOW Version 6.7.0
MODFLOW 6 is an object-oriented program and framework developed to provide a platform for supporting multiple models and multiple types of models within the same simulation (Hughes and others, 2017; Langevin and others, 2024). This version of MODFLOW is labeled with a "6" because it is the sixth core version of MODFLOW to be released by the USGS (previous core versions were released in...
MODFLOW 6: USGS Modular Hydrologic Model MODFLOW 6: USGS Modular Hydrologic Model
MODFLOW is a popular open-source groundwater flow model distributed by the U.S. Geological Survey.
USGS Analysis Ready Data Python Examples USGS Analysis Ready Data Python Examples
This product contains Jupyter Notebooks demonstrating how to retrieve, process, and analyze USGS analysis ready data (ARD) using Python. The purpose of these examples is to introduce novice Python users to real-life earth science data workflows. The examples include using the data retrieval package to pull NWIS data, pulling NOAA NOS CO-OPs water level data to visualize hurricane Helene...
