Purpose: To investigate abiotic processes controlling Al-P biogeochemistry of oligotrophic systems from soil to lake sediment. This study will determine

  • soil properties influencing Al-P mobility;
  • stream chemistry draining these same soils during varying stream discharge;
  • the interaction of the stream water with stream sediments; and
  • the long-term record in lake sediments, derived from the same streams, for metals including aluminum, iron, and phosphorus, and diatoms.

Develop a Citizen-Based Monitoring Plan for Mercury in Gauged Watershed Streams at Acadia National Park
Sarah Nelson, University of Maine (Orono)
Purpose:

  • to continue the long-term record of mercury data in paired research watersheds at Acadia National Park
  • to determine the appropriate timing and frequency of sampling to capture the essential data used to calculate mercury budgets in the watersheds
  • to develop a long-term monitoring plan for mercury in these watersheds that includes high school students as citizen scientists

Nutrient Loading to the Sieur de Monts Spring, Acadia National Park
