The American Alpine Institute has teamed up with the American Climber Science Program to support a variety of important research projects in mountain environments. The Institute’s role is to provide technical training to scientists, research assistants, student participants, and volunteers, and to recruit volunteers to assist with data collection while enjoying superb trekking and climbing in Peru's Cordillera Blanca.

High mountain regions – especially those with glaciers – are a treasure trove of important data that can inform upon the functioning and health alpine ecosystems and their individual components.  Because high mountain and alpine environments are quite fragile, measurable indicators of change are commonly generated more rapidly than in lower altitude ecosystems.  As a result, the data collected there can more quickly inform upon the evolution of both chronic and acute impacts than data in other ecosystems can.

Glaciers are great collectors of data.  Surface deposits do not go away, and they can be measured at any time for identification of the matter that composes them including:

  • living organisms – microbiomes fed by nutrients in dust;
  • black carbon, formed through the incomplete combustion of fossil fuels, biofuel, and biomass –  caused both by human activity and such things as naturally occurring vegetation fires;
  • heavy metals from open pit mining with a several hundred-mile radius.

Additionally, if researchers go high enough on glaciers (above the ablation line where annual snow accumulation exceeds annual snowpack melt) rates of accumulation over a number of years can be measured from annual layer sampling.

Though surface deposits are only one among many data banks in the alpine environment, they are an especially important in the study of pace and impacts of climate change because any degree of glacier covering by radiation absorbing pigment results in an acceleration of glacier melt, which depending the  specific location, can have immediate, medium, or long term impact on water supply and viability of human and all other life in the alpine ecosystem and downstream ecosystems.

The mission of this project

  • to improve access to important data found only at high altitudes on glaciers;
  • to use interdisciplinary studies, technical training, and research in mountain environments to improve graduate and undergraduate student skills in research, analysis, and writing;
  • to develop a collaborative mountain research community;
  • to facilitate the creation of successive generations of skilled mountain researchers; and
  • to foster the means to achieve effective stewardship and sustainable livelihoods in mountain regions.

Interdisciplinartiy as a Central Goal

In addition to wanting to augment detailed understanding of climate change, its rate, and its impacts, the Institute is also fully backing this ongoing research program because it believes in the high value of interdisciplinary study and research.  Interdisciplinary approaches to phenomena occurring in mountain environments are key to effective research, analysis, and understanding because:  

  • humans living within a particular ecosystem interact with it and affect it in many ways, and projections and public policy recommendation have to take into account “the human factor” and societal and/or individual resistance to changing (even destructive) habitual activities;
  • people living outside such an ecosystem can affect it in large and small ways from a distance (e.g., carbon consumption, open pit mining)
  • because ecosystems naturally evolve in complex ways on their own due to biological, chemical, atmospheric, aquatic, geological, and/or geographical shifts.

An extremely broad array of factors affect ecosystem characteristics and health, and typically the causes of change in either are so complex that a single-discipline-approach is less likely to produce the most informative and potentially helpful research.

In its own research, the Institute has also found that interdisciplinary studies give side benefits to researchers and students that include the development of:

  • a “second vocabulary” or way of observing, describing, and analyzing phenomena;
  • greater creativity in approaches to interpreting data and its implications for such diverse things as probable impacts on other ecosystem components and potential advisories on public policy;
  • greater skill in determining what research will be the most valuable.

In consideration of all these factors, the Institute is committed to supporting and augmenting further research in high mountain environments.  We anticipate that this research will:

  • fill in significant gaps in knowledge because so little research has been done in difficult-to-access high alpine ecosystems and
  • result in public policy recommendations for local, regional, and national air, water, and land management.

 


Scope of Research

The expedition research teams include scientists and educators in several fields, and the range of research includes:

  • the impacts of air pollution on the rate of melt of mountain glaciers
  • the composition and impacts of microbial communities on glacier melt
  • the indicators that surface deposits on glaciers provide for air pollution and general health of the ecosystem
  • methodologies for restoring alpine tundra from the effects of over grazing
  • water quality and content assessment
  • insect populations as indicators of ecosystem health
  • Our time in the mountains also includes work with local communities and land managers on conservation projects within Huascaran National Park.
