The 2014 Cordillera Blanca Peru expedition was a great success. Researchers and volunteers with the American Climber Science Program conducted a set of scientific research projects in Huascaran National Park in the Cordillera Blanca, Peru. Our expedition began with a different flavor than in the past as ACSP volunteers began with an archaeological visit to the Aukis Pukio region in the northern Cordillera Blanca.

In December 2013, the ACSP traversed the country of Costa Rica, crossing from the Pacific to the Atlantic Ocean. The purpose of the expedition was to collect ecological data across a long transect that passed through some of the most biologically diverse and undisturbed wilderness in Central America.

Glaciers in the tropical Andes have been melting at an alarming rate since the 1950s. Light absorbing particles on glacier surfaces may have been contributing to increases in melt rates. The goal of the black carbon research is to determine the types and amounts of light absorbing particles make it into the snowpack.
The tropics are projected to experience pronounced climatic change in the century yet our understanding of how forest functions will respond is incomplete. This presents a challenge since tropical forests play crucial roles in regulating Earth's biogeochemical cycles and climate.
