Abstract

Stream metabolism, or gross primary production and ecosystem respiration, is a fundamental property of stream ecosystems and is simple to measure in an instructional setting. In this chapter, we present theory on measuring stream metabolism based on diel oxygen curves, describe field methods to collect oxygen and associated data, and detail analytical methods for converting oxygen data to metabolism. The difficult aspect of estimating metabolism is quantifying air-water gas exchange and we present field and modeling methods to estimate this parameter. We also provide supplemental R code and spreadsheets to simplify the calculations.
