The Northern Gulf of Mexico (nGOM) is a hotspot for blue carbon biogeochemical cycles due to its ability to fix and sequester blue carbon and potential to mitigate rising atmospheric CO $$_2$$ concentrations. In this study, we employed a dataset containing >1100 sediment cores collected from seagrass beds paired with publicly available data to estimate C and N stocks within the surface mixed layer of seagrass meadows.

Alewife ( Alosa pseudoharengus ) and blueback herring ( A. aestivalis ) require connectivity among freshwater, estuarine, and marine environments to complete their life cycle. Impediments to watershed connectivity are major drivers of population declines along the eastern United States, where physical barriers and low-flow conditions can inhibit or delay juvenile outmigration, limiting access to productive estuarine nursery ha...
