Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, tree height and density 2021 Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, tree height and density 2021
On November 11, 2021, the height, density, and species richness of trees were recorded in five plots along a 175 m transect at Hickory Point State Forest near Pocomoke City, Maryland. This data was divided into categories depending on if the tree was alive, dead, or a sapling. Emergent species' height, density, and richness was also recorded.
Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, vegetation Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, vegetation
This dataset documents the water quality in depth, salinity, and pH as well as the vegetation found in the freshwater swamps of Hickory Point State Forest near Pocomoke City, Maryland from 2013 to 2021.
Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, CTD Diver data Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, CTD Diver data
This dataset represents data collected from 2018 to 2021 by a submersible datalogger known as a CTD Diver located in a well 48 cm below soil level at Hickory Point State Forest near Pocomoke City, Maryland.
USGS National and Global Oil and Gas Assessment Project-Senegal Basin Province: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project-Senegal Basin Province: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
This data release contains the boundaries of assessment units, assessment input data and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the Senegal Basin Province of northwest Africa. The Assessment Unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas...
Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, roots Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, roots
Annual root production over time was measured by collecting data on ingrowth into mesh root bags. The study was conducted on tidal freshwater swamp environments subjected to salinity intrusion at Hickory Point State Forest near Pocomoke City, Maryland. Root bags were collected at 5 set locations within the study area from 2013 to 2021 and analyzed to determine the weight in grams of new...
Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, SET Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, SET
This study was conducted using surface elevation tables (SETs) to determine the change in soil height over time. The study took place at Hickory Point State Forest near Pocomoke City, Maryland from 2015 to 2021. Instead of using the SETs to measure elevation, this dataset uses the concept of the height of the topographic surface established with respect to a local vertical datum, which...
PRMS simulator used to assess rainfall, runoff, and river flow for the National Hydrologic Model (NHM) Puerto Rico PRMS simulator used to assess rainfall, runoff, and river flow for the National Hydrologic Model (NHM) Puerto Rico
The National Hydrologic Model (NHM) is a modeling framework which has been applied to the continental United States through the Precipitation Runoff Modeling System (PRMS). The PRMS model of Puerto Rico extends the NHM and allows the simulation of rainfall-driven hydrologic conditions in the Commonwealth. Calibration of the NHM Puerto Rico model involved an initial manual calibration to...
Pesticide concentrations in bees and other matrices collected from sunflower fields (with and without a neonicotinoid seed treatment) near Sacramento, California Pesticide concentrations in bees and other matrices collected from sunflower fields (with and without a neonicotinoid seed treatment) near Sacramento, California
Hybrid sunflower production occurs near Sacramento in Northern California where seed treatments are commonly used. In this study, four locations were sampled in 2016 as matched pairs; half of each field was sown with thiamethoxam treated seed and half without. In addition to the thiamethoxam seed treatment, all seeds were coated with two fungicides, fludioxonil and mefenoxam/metalaxyl...
Inputs and Selected Outputs Used to Assess Stormwater Quality and Quantity in Twelve Urban Watersheds in Hampton Roads, Virginia, 2016 - 2020 Inputs and Selected Outputs Used to Assess Stormwater Quality and Quantity in Twelve Urban Watersheds in Hampton Roads, Virginia, 2016 - 2020
Nitrogen (N), phosphorus (P), and total suspended solids (TSS) loads, in Hampton Roads, Virginia stormwater conveyance systems have been calculated using monitoring data from 12 intensively monitored watersheds for the period from water year (October - September) 2016 through 2020. Nutrient and TSS loads were computed using a surrogate (multiple-linear regression) approach with lab...
Baseline High Resolution Land Cover Map for the Mainstem Klamath River Corridor Downstream of Iron Gate Dam, Klamath River, CA, 2018 Baseline High Resolution Land Cover Map for the Mainstem Klamath River Corridor Downstream of Iron Gate Dam, Klamath River, CA, 2018
This data release includes a file geodatabase with land cover maps for a 313-kilometer segment along the mainstem Klamath River corridor downstream from Iron Gate Dam, CA. The maps were derived from high-resolution (15cm) imagery and topobathymetric elevation data, collected by NV5 Geospatial (formerly QSI, Inc) and published on Open Topography (https://doi.org/10.5069/G9DN436N)...
