Nutrient concentrations in many estuaries have increased over the past century due to increases in wastewater discharge and increased agricultural intensity, contributing to multiple environmental problems. Numerous biogeochemical and physical processes in estuaries influence nutrient concentrations during transport, resulting in complex spatial and temporal variability and challenges identifying predominant processes and thei...

We characterized five years of seasonal metabolic patterns in two tidal sloughs in Lower South San Francisco Bay, one surrounded by a broad tidal marsh and the other connected to restored salt ponds (ponds). Despite comparable seasonal dissolved oxygen (DO) patterns, the two sloughs exhibited markedly different seasonal metabolic rates. The in-depth analysis of these small intertidal systems reveals the complexity of processes...
