Data and Tools

Science Datasets

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.

Vermillion/Cannon River Bottoms raw vegetation data from transect data

Detailed point center quarter sampling (Mueller-Dombois and Ellenberg 1974) was conducted during late June along a 150-m long transect that started at a bird survey point. Four plots were sampled corresponding to the start, 50m, 100m and end points of each transect. At each of these four sample plots, species, diameter at breast height (dbh) and distance from the center of the p

Cottonwood Lake Study Area - Amphibians

This dataset contains the number of captured individuals recorded for each amphibian species surveyed in all wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota. While amphibians were the target of the surveys, reptiles (i.e., turtles, snakes) were also sometimes captured over the course of the surveys and are included in the data file.

Baseline aquatic contamination and endocrine status in a resident fish of Biscayne National Park

This is a collection of data on the contamination of water, fish, and sediments in Biscayne National Park and in canals that discharge into the national park. The water data are estimations of their concentrations in water based on sampling with passive water samplers (semi-permeable membrane devices and polar organic chemical integrative samplers). Also in this data set are estrogen eq

2009 Western Gulf of Mexico USACE Lidar-Derived Dune Crest, Toe and Shoreline

The Storm-Induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Lidar-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and...

Evaluation of a Trace Plant Density Score in Long Term Resource Monitoring (LTRM) Vegetation Monitoring Data

The Long Term Resource Monitoring (LTRM) program employs a destructive harvest method for sampling aquatic vegetation whereby a rake is dragged ~1.5 m over the substrate and plant materials are retrieved. The density of each species of submersed aquatic vegetation (SAV), and of all species combined, are scored based on the amount of plant material collected on the teeth of each ra
