Carbon and Nitrogen content of above- and belowground biomass across a coastal wetland salinity gradient in Louisiana, U.S.A. (2013-2014) Carbon and Nitrogen content of above- and belowground biomass across a coastal wetland salinity gradient in Louisiana, U.S.A. (2013-2014)
Percent total carbon (%TC) and percent total nitrogen (%TN) content of above- and belowground biomass were measured from mixed-species plots in four different wetland types in Coastal Louisiana in July 2013 and July–August 2014 (Stagg et al. 2017).

High-Resolution UAS-Based Optical and Thermal Infrared Imagery and Geospatial Data from Surveys of Lake Ontario Tributaries, New York (ver. 2.0, December 2025) High-Resolution UAS-Based Optical and Thermal Infrared Imagery and Geospatial Data from Surveys of Lake Ontario Tributaries, New York (ver. 2.0, December 2025)
This data release contains geospatial datasets that identify thermal zones across multiple reaches of four tributaries to Lake Ontario: St. Regis River, Salmon River, South Sandy Creek, and Sandy Creek. High-resolution uncrewed aircraft system (UAS)-based optical and thermal infrared imagery and ground level field observations are included. Shapefiles for each tributary reach identify...
Beach Profile Data Collected From Isla Verde, Puerto Rico Beach Profile Data Collected From Isla Verde, Puerto Rico
This dataset, prepared by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC), provides beach profile data collected at Isla Verde, Puerto Rico. Data were collected from 2022-2024 on foot by a person equipped with a Global Navigation Satellite System (GNSS) receiver and antenna affixed to a backpack outfitted for surveying location and elevation...
Great Lakes seamless water depth models generated at water levels 3 feet below to 10 feet above the published low water datum Great Lakes seamless water depth models generated at water levels 3 feet below to 10 feet above the published low water datum
Modifications were made to Great Lakes topobathy data to interpolate areas of missing near shore elevation data. Areas with missing elevation data were not interpolated where there was low confidence in the underlying depth. This included rivers, canals, harbors, lakes, reservoirs, etc. Areas important for targeting Phragmites australis management often lie within these aquatic...
Model Archive Summary and Time-Series Suspended-Sediment Concentrations Computed from a Surrogate Turbidity Regression at USGS station 11313405 Old River at Bacon Island, CA (2010-2019) Model Archive Summary and Time-Series Suspended-Sediment Concentrations Computed from a Surrogate Turbidity Regression at USGS station 11313405 Old River at Bacon Island, CA (2010-2019)
Continuous 15-minute time-series suspended-sediment concentration data computed from instream turbidity data. Turbidty data is managed by California Department of Water Resources (CDWR) using a YSI 6-series multi-parameter water quality sonde. Complete methods for turbidity data collection are described in attached methods document.
Model Archive Summary for Turbidity Derived Suspended-Sediment Concentrations at 11455350 Cache Slough at Ryer Island, Ca (2013-2018) Model Archive Summary for Turbidity Derived Suspended-Sediment Concentrations at 11455350 Cache Slough at Ryer Island, Ca (2013-2018)
Continuous 15-minute time-series suspended-sediment concentration (SSC) data, representative of the cross section, were computed from instream turbidity data and are acceptable to compute sediment transport. Instream turbidity data were collected at the same location of the ADVM. Sediment samples were collected along the channel transect shown in the channel cross section information...
