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.

Plant, soil, and microbial characteristics of marsh collapse in Mississippi River Deltaic wetlands Plant, soil, and microbial characteristics of marsh collapse in Mississippi River Deltaic wetlands
Site, field, and soil data collected from 14 sites along a chronosequence of wetland submergence on 15 – 17 October 2019 in a Louisiana salt marsh in Barataria Basin, part of the Mississippi River Deltaic Plain, along the northern Gulf of Mexico coast.
A Remote Sensing Approach to Characterize Winter Water Level Drawdown Patterns in Lakes A Remote Sensing Approach to Characterize Winter Water Level Drawdown Patterns in Lakes
This data release consists of four datasets that were used for evaluating winter drawdown patterns in 166 Massachusetts lakes greater than 0.3 km2 surface area. The first dataset (“Water area and level.csv”) provides water area and water level time series data of 166 lakes from 2016 to 2021. Water area and water level time-series data were derived from European Space Agency’s Sentinel 1...

Survey of potential viral pathogens in the ceca of pen-raised mallards Survey of potential viral pathogens in the ceca of pen-raised mallards
The threat posed by infectious diseases are a major concern for global public health and the role of migratory birds in pathogen transmission is increasingly under scrutiny. Enteric viral pathogen surveillance in migratory birds is a critical component of outbreak preparedness. The shedding of such pathogens through excrement into bodies of water located at migratory stop-over sites and...
Multichannel minisparker and chirp seismic reflection data collected during USGS field activity 2021-614-FA along the Palos Verdes Fault Zone Multichannel minisparker and chirp seismic reflection data collected during USGS field activity 2021-614-FA along the Palos Verdes Fault Zone
High-resolution multichannel seismic (MCS) and coincident Chirp sub-bottom data were acquired during USGS field activity 2021-614-FA aboard the R/V Sproul in May of 2021. The survey was conducted in the offshore region of southern California, specifically in the inner continental borderlands tectonic region. The focus of the survey was to collect seismic lines perpendicular to the Palos...
MODFLOW-2005 and SWI2 models for assessing groundwater and surface-water interactions in the Heeia Watershed, Oahu, Hawaii MODFLOW-2005 and SWI2 models for assessing groundwater and surface-water interactions in the Heeia Watershed, Oahu, Hawaii
Resource managers and users seek information that can be used to balance the needs of competing uses of groundwater and streamflow in the Heeia watershed, Oahu. A previously constructed steady-state numerical groundwater-flow model for the island of Oahu, Hawaii (https://doi.org/10.3133/sir20205126) using MODFLOW-2005 with the Seawater Intrusion (SWI2) package was used to examine the...
