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.

Concentration trends for lead and calcium-normalized lead in fish fillets from the Big River, a mining-contaminated stream in southeastern Missouri USA

Lead (Pb) and calcium (Ca) concentrations were measured in fillet samples of longear sunfish (Lepomis megalotis) and suckers (Catostomidae) collected in December 2005 from the Big River, which drains a historical mining area in southeastern Missouri, where a consumption advisory is in effect due to elevated Pb concentrations in fish.

Development of high surface area organosilicate nanoparticulate thin films for use in sampling hydrophobic compounds in sediment-Data

The data set describes the characterization of organosilica thin films for adsorbing the bioavailable fraction of PCBs from sediment collected near Anniston Alabama. We developed novel nanoporous organosilicate (NPO) film as an extraction phase for hydrophobic contaminants and demonstrated its application in water and sediment.

Development of a dual luciferase-fluorescamine assay adapted to a 384 micro-well plate format-Data

Two commonly used human breast luciferase transactivation cell bioassays, the VM7Luc4E2 cell bioassay and the MDA-kb2 cell bioassay were adapted to 384-well formats for HTS of endocrine-active substances. This data demonstrate that by accounting for protein amount in the cell lysates, antagonistic agents can easily be distinguished from cytotoxic agents in the MDA-kb2 and VM7Luc4E2 cell...
