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.

Little Saint Francis River chat pile orthoimagery and elevation products, Missouri, July 2019 Little Saint Francis River chat pile orthoimagery and elevation products, Missouri, July 2019
The products presented here document conditions at the Little Saint Francis River chat pile restoration site near Fredericktown, Missouri in July 2019. Imagery was collected shortly after the initiation of restoration actions. Images were collected using low-altitude flights of unoccupied aerial systems (UAS, or “drones”) and processed using structure-from-motion techniques to generate...
Biogeochemistry of Southwestern Lake Superior and Watershed, 2021-2023 Biogeochemistry of Southwestern Lake Superior and Watershed, 2021-2023
This is an update to a previously archived data set, which is available at https://doi.org/10.13020/4zwr-t415. Here, additional sites for 2021, and additional data for 2022 and 2023 are given. There will be no further updates. 570 station occupations occurred along Lake Superior’s southwest shoreline where data were collected from Lake Superior and its watershed in the region generally...
Data to support the role of the American Alligator (Alligator mississippiensis) in coastal wetland carbon dynamics Data to support the role of the American Alligator (Alligator mississippiensis) in coastal wetland carbon dynamics
Coastal wetlands store carbon in their soils. Carbon is produced by emergent biomass and in-situ root growth, as well as deposited through sedimentation. Burial of aboveground carbon within soils and disruption of long-term soil carbon storage are both influenced by the fauna present in coastal wetlands. Data were used to test the hypothesis that the American Alligator (Alligator...
Aerial Camera System Boresight Installation in Bangor, Maine Aerial Camera System Boresight Installation in Bangor, Maine
The US Geological Survey's Upper Midwest Environmental Sciences Center, in coordination with the US Fish and Wildlife Service's (USFWS) Branch of Migratory Bird Surveys, worked to develop, survey, and deploy an advanced aerial photography boresight in the town of Bangor, Maine. The intention of this boresight is to provide an extensive array of high-accuracy ground control points for the
Radar-based field measurements of gage-height and surface velocity and resulting cross-sectional area and discharge from 80 U.S. Geological Survey streamgages for various locations in Texas, 2021–24 Radar-based field measurements of gage-height and surface velocity and resulting cross-sectional area and discharge from 80 U.S. Geological Survey streamgages for various locations in Texas, 2021–24
The U.S. Geological Survey (USGS), in cooperation with the Texas Department of Transportation (TxDOT), deployed RQ-30 surface velocimetry sensors (hereinafter referred to as “RQ-30 sensors”) made by Sommer Messtechnik to collect radar gage-height data, cross section area, surface velocity, learned surface velocity, discharge, and learned discharge at 80 streamgages located in stream...
Abundance Within and Ratios Between Successive Juvenile Tree Size Classes based on Mean Annual Temperature for Ten Common Tree Species in the Northeastern and Midwestern USA from 2012-2021 Abundance Within and Ratios Between Successive Juvenile Tree Size Classes based on Mean Annual Temperature for Ten Common Tree Species in the Northeastern and Midwestern USA from 2012-2021
This data release contains a CSV dataset of the likelihood of sapling recruitment based on abundance of seedlings height classes and other stand and site-level factors. Maps accompany the CSV on how the relationship between temperature and relative survival and seedling/sapling abundance varies by size class for ten tree species in the northeastern and midwestern USA, and can be used to...
