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.

Wetlands in the state of Arizona Wetlands in the state of Arizona
We created a single map of surface water presence by intersecting water classes from available land cover products (National Wetland Inventory, Gap Analysis Program, National Land Cover Database, and Dynamic Surface Water Extent) across the U.S. state of Arizona. We derived classified samples for four wetland classes from the harmonized map: water, herbaceous wetlands, wooded wetlands...
1-D Deep Ventilation (1DDV) model for Crater Lake, Oregon, 1950-2100 1-D Deep Ventilation (1DDV) model for Crater Lake, Oregon, 1950-2100
This data release contains the source code for the 1-D Deep Ventilation (1DDV) model (written in the Matlab programming language), and the input and output data from that model that were used to simulate temperature, salinity, and dissolved oxygen (DO) at specific depths in the lake. The input data consisted of: 1. daily average surface water temperature either a. collected by...
Code to Support Hypoxia vulnerability in the salmon watersheds of Southeast Alaska Code to Support Hypoxia vulnerability in the salmon watersheds of Southeast Alaska
Oxygen depletion events (hypoxia) in coastal aquatic ecosystems occur more frequently, yet their causes and consequences remain poorly understood. We identified key drivers of hypoxia in Southeast Alaska watersheds for long-term hypoxia monitoring. This software release contains one R script that can be used to calculate hypoxia risk from environmental variables. This R code will re...
Estuarine vegetated wetland change scenarios for estuaries in the conterminous United States, 1996–2019 Estuarine vegetated wetland change scenarios for estuaries in the conterminous United States, 1996–2019
This data release contains land cover-derived statistics regarding estuarine vegetated wetland area change within estuary drainage areas along the conterminous U.S. This dataset includes net change in estuarine vegetated wetland area based on National Oceanic and Atmospheric Administration's (NOAA) Coastal Change Assessment Program (C-CAP) 1996 and 2016 land cover data. Net change was...
Hypothetical landslide failure extents for hazard assessment, Barry Arm, western Prince William Sound, Alaska Hypothetical landslide failure extents for hazard assessment, Barry Arm, western Prince William Sound, Alaska
This data release contains extent shapefiles for 16 hypothetical slope failure scenarios for a landslide complex at Barry Arm, western Prince William Sound, Alaska. The landslide is likely active due to debuttressing from the retreat of Barry Glacier (Dai and others, 2020) and sits above Barry Arm, posing a tsunami risk in the event of slope failure (Barnhart and others, 2021). Since...
Water quality, nutrient, and phytoplankton data from Franks Tract, Mildred Island, and neighboring channels in the California Sacramento-San Joaquin Delta: 2022 and 2023 High-resolution mapping surveys Water quality, nutrient, and phytoplankton data from Franks Tract, Mildred Island, and neighboring channels in the California Sacramento-San Joaquin Delta: 2022 and 2023 High-resolution mapping surveys
Surface water quality, water isotope, and phytoplankton enumeration data were collected to evaluate the impact of an Emergency Drought Barrier (EDB) in False River in the Sacramento-San Joaquin Delta. Data were collected on six days during 2022 and 2023 (June 7, June 21, July 27, August 9, October 12, November 30, 2022, and February 21, 2023). Sampling occurred in Franks Tract, Mildred...
