Profile Leveling and Cross Sections

182
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes.  Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

Area of Science:

  • Earth and Environmental Sciences
  • Ecology
  • Climate Science

Background:

  • Peatlands cover 12% of Canada and are crucial for carbon cycling due to long-term carbon storage.
  • Understanding peatland carbon dynamics is vital for natural climate solutions and national greenhouse gas inventories.

Purpose of the Study:

  • To develop and parameterize the Canadian Model for Peatlands (CaMP v. 2.0) database.
  • To compile and analyze peat profile data across Canada for carbon stock estimation.
  • To support the inclusion of peatlands in national greenhouse gas inventories and climate change modeling.

Main Methods:

  • Compiled data from 1217 peatland sites across Canada.
  • Analyzed peat profiles for bulk density, carbon content, and hydrological responses.
  • Utilized interpolation and regression trees to fill data gaps for carbon mass estimation.

Main Results:

  • Developed a comprehensive database (CaMP v. 2.0) with site location, carbon mass, and profile data.
  • Estimated total carbon mass per unit area for numerous Canadian peatland sites.
  • Included geochemical data for a subset of sites, enhancing the dataset's utility.

Conclusions:

  • The CaMP v. 2.0 database provides essential data for carbon stock mapping and ecosystem modeling.
  • This resource facilitates the integration of peatland carbon dynamics into climate change assessments.
  • The data is publicly accessible on Open Government Canada for future research and policy development.
