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.

Microbial and environmental dataset from Crocker Reef, Florida Keys, 2014-2015
Crocker Reef was the site of an integrated reefscape characterization effort focused on calcification and related biogeochemical processes as part of the USGS Coral Reef Ecosystem Study (CREST) project. This effort included two intensive seasonal sampling trips to capture summer (July 8 to 17, 2014) and winter (January 29 to February 5, 2015) conditions. This data release represents water column m
Ecological Process Monitoring in the Western Basin Lake Erie, 2013.
This dataset includes information collected from “ecological process monitoring stations� located across the western basin of Lake Erie (originating at the Maumee River and reaching as far east as the Bass Islands). Nine worksheets are included in this file, of which 1 is a meta-data sheet that describes the variable names and purpose of the other sheets. Included herein is th
Southwest U.S. Mechanically Treated Chaparral Photo Series
Accurate, complete fuels data are critical for making fuel management decisions and for predicting fire behavior and fire effects. A fuel photo series is a useful reference that allows natural resource managers to quickly quantify fuel and vegetation properties by comparing on site conditions to a series of photos showing a range of calculated fuel loads within a similar vegetative community. Whil
Raw Ground Penetrating Radar Data, Eklutna Glacier, Alaska; 2013
Common-offset GPR surveys were conducted with a Sensors and Software 500-MHz Pulse Ekko Pro system. We collected data from the ground, towed behind a researcher on skis or snowmobile, and from the air, strapped underneath a helicopter. All of the profiles are linked to coincident GPS observations. Coincident in-situ data is provided for calibration, and may be composed of any of the following: sn

Louisiana Gas and Oil Fields with Cumulative Production from 1977 - 2014
This dataset represents the producing, dry holes, wildcat wells and wells that have other well type categories other than the ones mentioned previously in Louisiana. These wells were used to create gas and oil field polygons. The field polygons include discovery data, number of producing wells in the field, average measured depth of those well, total gas and oil production from 1977-2014, gas oil
Assessing the robustness of quantitative fatty acid signature analysis to assumption violations (Supplementary data)
This dataset contains fatty acid (FA) data expressed as mass percent of total FA for bearded seals, ringed seals and walrus. This is one of many datasets used in Bromaghin et al., In press, Assessing the robustness of quantitative fatty acid signature analysis to assumption violations, Methods in Ecology and Evolution. These supplemental data were used in computer simulations to compare the bias o
