Summary

This data release presents results from a laboratory study designed to measure the effect of temperature on denitrification rates in sediments collected from 5- to 30-cm depth below the lake bottom, at a location where groundwater discharges to the lake. Sediment cores were collected June 25, 2014 from the West site (Fishermans Cove) in Ashumet Pond, Cape Cod, MA then shipped to Boulder, CO for laboratory experiments. Groundwater used for these experiments was collected from a well just upgradient of the sediment collection site. Denitrification rates were determined on sediment plus groundwater slurries maintained under anaerobic conditions and employing the acetylene block method. Nitrous oxide concentrations were measured several [...]

Purpose

The purpose of the data release is to provide a measure of denitrification rates that can be applied to various models to assess biogeochemical processes predominant in Ashumet Pond sediments subjected to discharge from a groundwater wastewater plume.
