Diatom-based transfer functions for pH and total phosphorus in Vermont, USA lakes
2025
Overview
Lakes are inextricably connected to their adjacent landscape, acting as dynamic integrators of auto- and allogenic stressors. These processes are recorded in lake sediments and can be inferred and reconstructed using paleolimnological proxies. Like much of the Northeastern USA, Vermont lakes are changing rapidly in response to multiple stressors. This includes more than 800 lakes that span gradients of elevation, latitude, trophic status, depth, clarity, and watershed area. Long-term monitoring data indicate that all oligotrophic lakes in the state have experienced a near-doubling in total phosphorus (TP) over the past four decades, a trend unique to Vermont that is not occurring in neighboring states. Many montane lakes recovering from acidification are now experiencing browning and rapid surface-water warming. Understanding these interacting trends at long-term scales requires proxy-based reconstruction of sediment records. Here we describe regional training sets and transfer functions for TP and pH developed using modern water chemistry and sediment diatom records from 80 and 96 lakes, respectively, spanning chemical, trophic, latitudinal, and elevation gradients. TP and pH were chosen because they are known stressors to Vermont lakes and have been shown to correlate with diatom assemblages in previous work in the region. We used weighted-averaging partial least squares regression to reconstruct diatom-inferred TP and pH (DI-TP, DI-pH) for the period predating the European settlement of the state (~ 1800) using a top–bottom approach for 96 lake cores. We present a high-resolution reconstruction of these variables for acid-impaired, mesotrophic Beaver Pond and compare with long-term monitoring records. Based on our findings, we present recommendations and limitations for model application.
