Researchers at the USGS Spectroscopy Lab are studying and applying methods for identifying and mapping materials through spectroscopic remote sensing (called imaging spectroscopy, hyperspectral imaging,imaging spectrometryultraspectral imaging, etc), on the earth and throughout the solar system using laboratoryfieldairborne and spacecraft spectrometers.

USGS Scientists Develop New Tool to Determine if Vermiculite Insulation Contains Asbestos

U.S. Geological Survey scientists and partners have created an onsite, time-saving technique for building inspectors to ascertain whether vermiculite insulation contains amphibole asbestos. The findings are featured in the April 2 edition of American Mineralogist.

Characterizing the source of potentially asbestos-bearing commercial vermiculite insulation using in situ IR spectroscopy

Commercially produced vermiculite insulation from Libby, Montana, contains trace levels of asbestiform amphibole, which is known to cause asbestos-related diseases. When vermiculite insulation is found in a building, evaluation for its potential asbestos content traditionally involves collecting a sample from an attic or wall and submitting it for...

Oiling accelerates loss of salt marshes, southeastern Louisiana

The 2010 BP Deepwater Horizon (DWH) oil spill damaged thousands of km2 of intertidal marsh along shorelines that had been experiencing elevated rates of erosion for decades. Yet, the contribution of marsh oiling to landscape-scale degradation and subsequent land loss has been difficult to quantify. Here, we applied advanced remote sensing...
