Article Synopsis
- Researchers assessed the impact of nonpoint source nutrients on the eutrophic Barnegat Bay, using stable isotope measurements of nitrogen and carbon across 35 sampling stations.
- The study identified four geographic zones with different isotopic baselines, indicating varied nutrient sources and processing pathways, revealing a clear terrestrial-marine gradient.
- Findings showed that nitrogen signatures in the urbanized area were less influenced by anthropogenic runoff than expected, and over time, nitrogen values in consumers have decreased, highlighting water quality issues particularly in the poorly flushed regions of the bay.
Tidal wetlands in the Mid-Atlantic, USA, are experiencing high rates of relative sea level rise, and it is unclear whether they will be resilient in the face of future flooding increases. In a previous study, we found 80% of our study areas in tidal freshwater and salt marshes in the Delaware Estuary and Barnegat Bay had elevation change rates lower than the 19-year increase in mean sea level. Here, we examine relationships between marsh elevation dynamics and abiotic and biotic parameters in order to assess their utility as indicators of vulnerability to relative sea level rise.
