We measured chlorophyll concentrations in the surface waters and sediments of six ponds in three regions of the PIE-LTER marshes during summer 2016. The goal was to assess whether pond microalgal community abundances varied predictably with pond dimensions (e.g., surface area, volume) or geographic attributes (e.g., elevation, distance from upland, marsh region). Samples were collected from several locations in each pond in order to capture spatial heterogeneity.
