    Coleman, Daniel J.; Ganju, Neil K.; Kirwan, Matthew L. (American Geophysical Union, 2020-06-27)
    Sediment supply is a primary factor in determining marsh response to sea level rise and is typically approximated through high‐resolution measurements of suspended sediment concentrations (SSCs) from adjacent tidal channels. ...

Patrick; Bond-Lamberty, Benjamin; Bailey, Vanessa L.; Butman, David; Canuel, Elizabeth A.; Diefenderfer, Heida; Ganju, Neil K.; Goni, Miguel; Graham, Emily B.; Hopkinson, Charles S.; Khangaonkar, Tarang; Langley, J. Adam; McDowell, Nate G.; Myers-Pigg, Allison N.; Neumann, Rebecca B.; Osburn, Christopher L.; Price, René M.; Rowland, Joel; Sengupta, Aditi; Simard, Marc; Thornton, Peter E.; Tzortziou, Maria; Vargas, Rodrigo; Weisenhorn, Pamela B.; Windham-Myers, Lisamarie (Nature Research, 2020-05-18)
    Between the land and ocean, diverse coastal ecosystems transform, store, and transport material. Across these interfaces, the dynamic exchange of energy and matter is driven by hydrological and hydrodynamic processes such ...
  • Are elevation and open-water conversion of salt marshes connected? 

    Ganju, Neil K.; Defne, Zafer; Fagherazzi, Sergio (American Geophysical Union, 2020-01-29)
    Salt marsh assessments focus on vertical metrics such as accretion or lateral metrics such as open‐water conversion, without exploration of how the dimensions are related. We exploited a novel geospatial data set to explore ...

    Shi, Luming; Olabarrieta, Maitane; Nolan, David S.; Warner, John C. (Nature Research, 2020-02-02)
    Tropical cyclones are one of the most destructive natural hazards and much of the damage and casualties they cause are flood-related. Accurate characterization and prediction of total water levels during extreme storms is ...
