Article: Patterns of dissolved oxygen, productivity and respiration in Old Woman Creek estuary, Erie county, Ohio during low and high water conditions.(Report)

ABSTRACT: Old Woman Creek wetland is composed of a stream and freshwater estuary and may act as a sink or transformer of nutrients entering Lake Erie. Primary productivity and respiration are indicators of ecosystem level trophic conditions and may be linked to the estuary's effectiveness as a nutrient sink or transformer. Old Woman Creek National Estuarine Research Reserve has been collecting water chemistry data at 15 minute intervals using data loggers since 1995. Both did and seasonal trends in water temperature, dissolved oxygen, and water depth at selected sites in the creek and estuary were related to physical and biological processes. Daily primary productivity ...
