  • July 15, 2016 to August 20, 2016

    Join us in the Cordillera Blanca July - August 2016!

    Applications are due May 15, 2016.

    Starting in July 2016, the ACSP will host our 6th annual Cordillera Blanca research expedition. Scientists, volunteers, students, and mountaineers are invited join us for a summer of research, conservation and adventure in Huascaran National Park.

    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.


  • 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.
