Collecting a Gas Hydrate Research Core from the Indian Ocean
Collecting a Gas Hydrate Research Core from the Indian OceanScientists aboard the D/S Chikyu prepare to collect a research core drilled from marine sediments in the Indian Ocean. This research is part of the 2015 Indian National Gas Hydrate Program Expedition 02 (NGHP-02), which is a follow-up to the 2006 NGHP-01.

Finchite Mineral
A sample of finchite, a newly discovered uranium mineral. Finchite is the yellow material on the surface of the rock. Finchite is found in the late Pleistocene sediments deposited during the Illinoian glacial stage.

USGS scientists Chris Rowden, Larry Buschmann and Bob Holmes were on the Mississippi River at St. Louis taking streamflow measurements on New Years Eve. This information is critical to the National Weather Service, the U.S. Army Corps of Engineers and emergency managers in making flood predictions and response.
