Data from 92 sediment incubation experiments using sediments collected from the Fox and Duck rivermouths (adjacent to Green Bay, Lake Michigan)

This dataset contains measurements of water chemistry taken from experimental incubation of sediment cores collected from the Fox and Duck rivermouths during the 2016 growing season. In addition, some characteristics of the sediment were recorded. This data can be used to generate estimates of nutrient change over time, due to flux of nutrients from the sediments. These flux estimates (or release rates) can be used to estimate total flux from sediments to the surface waters over the course of the 2016 growing season. This dataset is a subset of a larger effort to quantitatively estimate the effect of rivermouths on nutrient loading to Lake Michigan.

Code associated with analysis and modeling of benthic and pelagic inorganic nutrient processing rates at the interface between a river and lake

In this data release the authors have code and 'data' that are used to model how sediment flux and water column processing of soluble reactive phosphorus (SRP), ammonium (NH4/NHX) and nitrate (NOX). The file 'README.md' contains background information on how to access and use the data and code files.

Data from water column and sediment incubations from streams of Duck Creek and Fox River watersheds in Wisconsin, as well as the Fox rivermouth, the Saginaw rivermouth (Lake Huron, MI) and the Maumee rivermouth (Lake Erie, OH)

Nutrient reduction on the landscape scale often focuses on actions that reduce the movement of nitrogen (N) and phosphorus (P) from agricultural lands into streams and rivers. However, processing of N and P in streams and rivers can be substantial and increasing these in-stream processing rates could result in reductions or transformations of nutrients to less labile or less mobile forms. We hypothesize that buffer conditions could influence the microbial community and sediment characteristics of streams and rivers and thereby influence in-stream N and P processing rates. As a result, we predict that variation in buffer land cover (from agricultural to wetlands to forest) causes differences in processing rates....
