REU participants enjoy access to the department's research facilities.

The Department of Earth System is housed in the School of Physical Sciences. The department is based in Croul Hall, which opened in 2004 and offers state of the art research facilities, including high quality biogeochemical laboratories, computer modeling labs, and meeting facilities.

Experimental facilities include trace gas and seawater analysis, numerous gas source stable isotope mass spectrometers, a medium resolution ICP-MS for trace metal and isotopic analysis, high resolution analytical mass spectrometry for atmospheric gases, and electrospray MS/MS for organic analysis.

The department operates the Keck Carbon Cycle AMS laboratory. This is a unique facility for the use of accelerator mass spectrometer in carbon cycle research.

Advanced modeling facilities allow students to work with global-scale models of atmosphere, ocean and terrestrial systems, and with coupled Earth system components. These facilities include the Earth System Modeling Facility and Green Planet. Green Planet is a cutting edge Linux cluster, with fast Infiniband switches connecting nodes.  Each node on this cluster has two Quad Core Xeon E5420 Processors (2.5 GHz) with 16 GB memory.  The Department of Earth System Science controls 90 nodes (720 cpus) on this system with 26 TB of disk space. The system was designed to support the complex simulations typical of large Earth System Science modeling projects.

Each REU student will have their own desk space and computer with necessary software (MS Office, IDL, ENVI, MATLAB, etc.) for their exclusive use during the program. In addition, students will have access to university computer labs and analytical facilities (mass spectrometer, NMR, spectroscopy, machine and electronic shops).
