WHOI postdoctoral fellow Nicole Keller (Geology & Geophysics) takes a break from hiking the Barva volcano in Costa Rica in June 2008 to surround herself with the monstrous leaf of the Sombrillo de Pobre (“poor man’s umbrella”, or Gunnera insignis). Keller and WHOI volcanologist Alison Shaw hiked the volcano to collect samples ash and rock samples for a study of the sulfur cycle in volcanic systems.
