Research Facilities

The Department of Earth Sciences is loosely divided into three working research divisions, with numerous laboratories and research facilities at the disposal of department personnel. However, many faculty and students also work across these disciplinary boundaries.

Analytical and Experimental Laboratories

Sea-Going Facilities

The following research vessels and their supporting shipboard technical group, are available to researchers for gathering geophysical, geochemical and other open ocean and coastal data and samples:

R/V Kilo Moana (AGOR26 swath ship)

Luukai, a DOER-H6000 ROV (remotely-operated underwater vehicle) - NEW in 2013

Sea-going instrumentation includes equipment for digital seismic reflection, gravity, magnetics, coring, dredging, and water column studies, the HAWAII MR1 side-scan sonar system, and fiber optic-based deep-towed FOCUS camera system. In addition, software is available for multi-channel seismic processing and geophysical data analysis.


Students are encouraged to take advantage of opportunities for cooperative, interdisciplinary research. Cooperative research is also carried out with other units of the University and federal laboratories in Hawaii. Some of these are:
