High-resolution topography characterizes landform geometry at scales at which geomorphic processes operate. A) Widely available 10 m per pixel National Elevation Data (NED) with San Andreas Fault (SAF) traces (last slippage here in 1906 of 1-2 m) overlain in the Fort Ross area of coastal northern California (inset yellow rectangle). Box shows location of B. B) 1 m per pixel full feature airborn laser swath mapping (ALSM) digital elevation model with canopy thickness in green. NED data are from US Geological Survey. EarthScope ASLM data are from http://www.opentopography.org.

Representative geohazards that can originate along continental and volcanic margins. (Figure modified from Morgan et al. [2009]).

A schematic diagram showing a model for how H isotopes in Earth reservoirs are cycled through subduction zone systems. The effect of the dehydration process on H isotopes is illustrated assuming 92% dehydration of the slab and a case where the fluids released have an average dD of -34 0/00.

Figure from Wada and Wang [2009] showing an example for a young slab subduction zone, and including the locations of slab dehydration relative to key mechanical and rheological transition along the subduction interface, including the seismogenic zone and its down-dip edge where ETS has been observed, potential serpentinization of the mantle wedge, and kinematic coupling between the down-going slab and mantle wedge.

This animation describes how the Autonomous Underwater Vehicle (AUV) ABE is operated to map the seafloor. Sent along a predetermined survey pattern, the AUV uses multibeam sonar to collect data that is used to generate bathymetric maps.

This animation shows the evolution of hydrothermal vent systems that occur at underwater volcanoes. Warm mineral-rich water released from the seafloor creates suitable habitat for organisms including tubesorms (Riftia pachyptila) and clams. Over time, the distribution of these organisms within their habitat can change, as individuals die and are replaced by others. Major disturbance to the ecosystem occurs during voclanic eruptions then the area is inundated with hot molten lava.

This video shows various aspects of the geology and biology of the well-studies hydrothermal vent site called Bio 9 at the East Pacific Rise (EPR).
