General Interests

Marty Kleinrock's main research interests revolve around the generation and deformation of the crust of the Earth. His work takes him to the far corners of the globe where he gets on ships and goes to sea for a month at a time. During these cruises, he uses state-of-the-art remote sensing instruments and deep-diving submersibles to investigate the bottom of the ocean to understand the processes occurring in active tectonic and volcanic provinces, especially along midocean ridge spreading systems where most of the Earth's crust has been created.

Current Research

Kleinrock and his students are studying volcanoes, faulting, hydrothermal activity, and mass wasting near "TAG", one of the largest known hydro-thermal vent systems on the midocean ridge. Kleinrock also works on tectonics of offsets of spreading axes. He is studying the mechanisms of lithospheric deformation associated with migrating non-transform offsets, which are now known to be far more common along midocean ridges than classical transform faults. Strike-slip tectonics and compressional systems in young oceanic crust are increasing foci of Kleinrock's work as well.
