Previous Expeditions

    The first ACSP-Cusco expedition was successfully completed in August, 2015. Our objective was to measure black carbon in the mountains around the region.  Black carbon is a common by-product of fossil fuel combustion and biomass burning. Black carbon is a highly light-absorbing pollutant, and along with the effects of a warming climate, it is accelerating the rate of glacier loss.

    The ACSP's 5th annual Cordillera Blanca research expedition was extremely successful and productive! Between June 15th and August 10th, our team of scientists, students, and volunteers collected data on glaciers, water quality, native plant and animal communities, and studied the impacts of overgrazing in high mountain valleys.


  • 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.

  • Tropical mountains are facing a host of environmental stressors, including warming temperatures and land-use change. How hydrologic and biogeochemical cycles respond will impact the provision of key ecosystem services and is a critical research topic with implications from local to global scales.
