As part of an investigation of the mechanisms of coastal change in the Carolinas, instrumented tripods were deployed on Diamond Shoals near Cape Hatteras, NC.

As part of an investigation of the mechanisms of coastal change in the Carolinas, instrumented tripods were deployed on Diamond Shoals near Cape Hatteras, NC. These tripods recorded data quantifying the currents, waves, turbidity, temperature and salinity at several levels near the seafloor between January and April 2009.

Data from THEMIS helped scientists choose a landing site for the Mars Science Laboratory (MSL), NASA's next-generation rover spacecraft, due to arrive at Gale Crater in August 2012.

Mounds in Acidalia Planitia, Mars. These are almost certainly not cinder cones despite their appearance. Their alignment in rows is not typical of cinder cones on Earth; more likely these are mud volcanoes formed from the shaking of an impact event.

Cratered cones near Hephaestus Fossae, Mars. This might look at first glance like a cinder cone, but it is more likely an impact crater. Using the shadow, one can tell that its floor is at a lower elevation than the surrounding landscape. A cinder cone would rise above the landscape.
