Estimate of sediment accumulation rates and bottom core ages in northeast lakes

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: June 27, 2025 | Last Modified: 2023-09-26
Supplementary data for the report in the format of an Excel spreadsheet (with data dictionary) and an Microsoft Access database file (downloaded as a zip file). The Access database file contains multiple data tables examined or generated during the project to investigate sediment accumulation rates (SAR) of northeast lakes. 1. Baud_SARMAR: data downloaded from Baud et al. 2019 for northeast lake sediment accumulation rates. 2. EPA_Extra_Chron_Data: additional lake sedimentation chronology data. 3. Lake_Metadata_n701: coordinates, waterbody type, area, elevation, and slope information. 4. Neotoma_Chron_Data: lake sediment core depth, age estimates, and age model info downloaded from Neotoma. 5. RARE_Sample_Metadata: RARE project lakes' name, collection date, source. 6. SAR_Calc_1850_n691: data for variables required by the Baud SAR equation. 7. SAR_Comparison_Results: comparison of observed and predicted SAR. 8. Stations_RARE_Neotoma_Crosswalk: data used to match RARE project lakes with lakes from Neotoma to confirm they are the same lakes.
