Abstract:

This datataset contains the datatables from Leys et al. 2016, and report a high-resolution millennial-scale record of Ca and 16 other elements from the sediments of Mirror Lake, a 15-ha lake in the White Mountains of New Hampshire surrounded by northern hardwood forest.

Leys, B. A., G. E. Likens, C. E. Johnson, J. M. Craine, B. Lacroix, and K. K. McLauchlan. 2016. Natural and anthropogenic drivers of calcium depletion in a northern forest during the last millennium. Proceedings of the National Academy of Sciences 113:6934 - 6938.
