    • The interaction of climate change and methane hydrates 

      Ruppel, Carolyn D.; Kessler, John D. (John Wiley & Sons, 2017-02-08)
      Gas hydrate, a frozen, naturally-occurring, and highly-concentrated form of methane, sequesters significant carbon in the global system and is stable only over a range of low-temperature and moderate-pressure conditions. ...

      Nowacki, Daniel J.; Beudin, Alexis; Ganju, Neil K. (John Wiley & Sons, 2017-01-11)
      Submerged aquatic vegetation is generally thought to attenuate waves, but this interaction remains poorly characterized in shallow-water field settings with locally generated wind waves. Better quantification of wave–vegetation ...
    • Development of a coupled wave-flow-vegetation interaction model 

      Beudin, Alexis; Kalra, Tarandeep S.; Ganju, Neil K.; Warner, John C. (Elsevier, 2016-12-15)
      Emergent and submerged vegetation can significantly affect coastal hydrodynamics. However, most deterministic numerical models do not take into account their influence on currents, waves, and turbulence. In this paper, we ...
    • Effects of climate change and anthropogenic modification on a disturbance-dependent species in a large riverine system 

      Zeigler, Sara L.; Catlin, Daniel H.; Brown, Mary Bomberger; Fraser, James D.; Dinan, Lauren R.; Hunt, Kelsi L.; Jorgensen, Joel G.; Karpanty, Sarah M. (John Wiley & Sons, 2017-01-11)
      Humans have altered nearly every natural disturbance regime on the planet through climate and land-use change, and in many instances, these processes may have interacting effects. For example, projected shifts in temperature ...

      Safak, Ilgar; Warner, John C.; List, Jeffrey H. (John Wiley & Sons, 2016-12-16)
      Physical processes controlling repeated openings and closures of a barrier island breach between a bay and the open ocean are studied using aerial photographs and atmospheric and hydrodynamic observations. The breach site ...
    • Dynamic reusable workflows for ocean science 

      Signell, Richard P.; Fernandes, Filipe; Wilcox, Kyle (MDPI AG, 2016-10-25)
      Digital catalogs of ocean data have been available for decades, but advances in standardized services and software for catalog searches and data access now make it possible to create catalog-driven workflows that ...
    • Observations and 3D hydrodynamics-based modeling of decadal-scale shoreline change along the Outer Banks, North Carolina 

      Safak, Ilgar; List, Jeffrey H.; Warner, John C.; Kumar, Nirnimesh (Elsevier, 2016-12-10)
      Long-term decadal-scale shoreline change is an important parameter for quantifying the stability of coastal systems. The decadal-scale coastal change is controlled by processes that occur on short time scales (such as ...
