Spatial and temporal variation in sedimentary phosphorus species in Lake Champlain (Vermont, New York, Québec)

This scientific journal article by Suzanne Levine analyzed the distribution and accumulation of P in varying parts of the Lake Champlain Basin. 11 core sites were determined around the lake and the cores were analyzed in a lab for stable isotopes, pigments, diatoms, nutrients, 210Pb dating, etc. The sediment accumulation rates between the different cores varied dramatically. Concentrations of P varied both spatially and temporally in the analyses. The analysis split the historic accumulation of P into four intervals of development in the Lake Champlain Basin, pre-settlement, early-settlement, mid-settlement, and modern.
