Washington (Alpine Lake Wilderness & Mt. Rainer) Determining Critical Loads of Nitrogen Deposition in the Pacific Northwest Jasmine Saros August 2008 Paleolimnological studies in the Pacific Northwest have suggested possible acidification effects of nitrogen (N) and sulfur (S) deposition on alpine lakes in this region, but have been unable to generate a critical load at […]

Rocky Mountains – 2007 & 2008 Mapping Critical Loads of Atmospheric N and S deposition in the Rocky Mountains Jasmine Saros, Heather Arnett Critical Loads are the amount of deposition of a given pollutant that an ecosystem can receive below which ecological effects are thought not to occur.  In the proposed study, maps will be […]

Collaborative Research: Grounding-line retreat in the southern Ross Sea – constraints from Scott Glacier Brenda Hall, Gordon Bromley, Nate Nietkiewicz December 2007 – January 2008; December 2008 – January  2009 We are investigating late Pleistocene and Holocene changes in Scott Glacier, a key outlet glacier that flows directly into the Ross Sea just west of […]

Beartooth Mountains, Glacier National Park Climate-Induced Shifts in Alpine Diatom Communities: Linking Neoecological and Paleoecological Approaches to Incorporate Responses to Trophic Forcing Jasmine Saros, Andrea Nurse Field assistants from CCI: Carmen Daggett, Courtney Wigdahl, Randall Perry July 2007, August 2007, August 2008, July 2009 Diatom fossils from lake sediments in the central and northern Rocky […]

Acadia National Park (Maine) & Isle Royale National Park (Michigan) Determine critical nitrogen loads to boreal lake ecosystems using the response of phytoplankton Jasmine Saros, Carmen Daggett, Heather Arnett Air pollution has affected and continues to threaten many boreal lake ecosystems in the U.S. national parks. The lakes of Acadia and Isle Royale National Parks […]

New Zealand 2009 Ice Core Drilling in the Southern Alps Daniel Dixon The mid-latitudes of the Southern Hemisphere have proven particularly challenging for ice core retrieval and interpretation.  Glaciers in southern South America and the Southern Alps experience extraordinarily high rates of snow fall and melt which compromises the length and integrity of records from […]
