Summary

Lake water level fluctuations are an important factor driving variation in many ecosystem processes. The nearshore sediments that are periodically exposed and re-inundated can develop distinct physical and chemical characteristics, especially in relationship to the organic matter content of the sediments and the particle size distribution. These sediment characteristics in turn can alter the flux of nitrogen (N) and phosphorus (P) from sediments into the water column when sediments are inundated. Here we used intact sediment core experiments across a range of sediment inundation frequencies to estimate the effect of inundation frequency on sediment nutrient flux in Kabetogama Lake, MN. A total of 96 intact sediment core experiments [...]

Purpose

These data were collected to estimate the effect of water level fluctuation on sediment nutrient flux rate. Approximately half the samples came from sites that were occasionally or often exposed to atmosphere.
