  • Bora event variability and the role of air-sea feedback 

    Pullen, Julie; Doyle, James D.; Haack, Tracy; Dorman, Clive E.; Signell, Richard P.; Lee, Craig M. (American Geophysical Union, 2007-02-13)
    A two-way interacting high resolution numerical simulation of the Adriatic Sea using the Navy Coastal Ocean Model (NCOM) and Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS®) was conducted to improve forecast ...
  • Characterizing wave- and current- induced bottom shear stress : U.S. middle Atlantic continental shelf 

    Dalyander, P. Soupy; Butman, Bradford; Sherwood, Christopher R.; Signell, Richard P.; Wilkin, John L. (Elsevier B.V., 2012-11-05)
    Waves and currents create bottom shear stress, a force at the seabed that influences sediment texture distribution, micro-topography, habitat, and anthropogenic use. This paper presents a methodology for assessing the ...
  • Collaboration tools and techniques for large model datasets 

    Signell, Richard P.; Carniel, Sandro; Chiggiato, Jacopo; Janekovic, Ivica; Pullen, Julie; Sherwood, Christopher R. (2006-08-08)
    In MREA and many other marine applications, it is common to have multiple models running with different grids, run by different institutions. Techniques and tools are described for low-bandwidth delivery of data from large ...
  • High-resolution mapping of Bora winds in the northern Adriatic Sea using synthetic aperture radar 

    Signell, Richard P.; Chiggiato, Jacopo; Horstmann, Jochen; Doyle, James D.; Pullen, Julie; Askari, Farid (American Geophysical Union, 2010-04-24)
    The Adriatic Sea is regularly subjected to strong Bora wind events from the northeast during winter. The events have a strong effect on the oceanography in the Adriatic, driving basin-scale gyres that determine the transport ...
  • Introduction to special section on The U.S. IOOS Coastal and Ocean Modeling Testbed 

    Luettich, Richard A.; Wright, L. Donelson; Signell, Richard P.; Friedrichs, Carl T.; Friedrichs, Marjorie A. M.; Harding, John; Fennel, Katja; Howlett, Eoin; Graves, Sara J.; Smith, Elizabeth; Crane, Gary; Baltes, Rebecca (John Wiley & Sons, 2013-12-11)
    Strong and strategic collaborations among experts from academia, federal operational centers, and industry have been forged to create a U.S. IOOS Coastal and Ocean Modeling Testbed (COMT). The COMT mission is to accelerate ...
  • Investigating the importance of sediment resuspension in Alexandrium fundyense cyst population dynamics in the Gulf of Maine 

    Butman, Bradford; Aretxabaleta, Alfredo L.; Dickhudt, Patrick J.; Dalyander, P. Soupy; Sherwood, Christopher R.; Anderson, Donald M.; Keafer, Bruce A.; Signell, Richard P. (Elsevier, 2013-11-05)
    Cysts of Alexandrium fundyense, a dinoflagellate that causes toxic algal blooms in the Gulf of Maine, spend the winter as dormant cells in the upper layer of bottom sediment or the bottom nepheloid layer and germinate in ...
  • Near-bottom circulation and dispersion of sediment containing Alexandrium fundyense cysts in the Gulf of Maine during 2010–2011 

    Aretxabaleta, Alfredo L.; Butman, Bradford; Signell, Richard P.; Dalyander, P. Soupy; Sherwood, Christopher R.; Sheremet, Vitalii A.; McGillicuddy, Dennis J. (Elsevier, 2013-12-13)
    The life cycle of Alexandrium fundyense in the Gulf of Maine includes a dormant cyst stage that spends the winter predominantly in the bottom sediment. Wave-current bottom stress caused by storms and tides induces resuspension ...
  • Sediment dispersal in the northwestern Adriatic Sea 

    Harris, Courtney K.; Sherwood, Christopher R.; Signell, Richard P.; Bever, Aaron J.; Warner, John C. (American Geophysical Union, 2008-10-29)
    Sediment dispersal in the Adriatic Sea was evaluated using coupled three-dimensional circulation and sediment transport models, representing conditions from autumn 2002 through spring 2003. The calculations accounted for ...
  • Surface drift prediction in the Adriatic Sea using hyper-ensemble statistics on atmospheric, ocean and wave models : uncertainties and probability distribution areas 

    Rixen, M.; Ferreira-Coelho, E.; Signell, Richard P. (Elsevier B.V., 2007-02-20)
    Despite numerous and regular improvements in underlying models, surface drift prediction in the ocean remains a challenging task because of our yet limited understanding of all processes involved. Hence, deterministic ...
  • U.S. IOOS coastal and ocean modeling testbed : inter-model evaluation of tides, waves, and hurricane surge in the Gulf of Mexico 

    Kerr, Patrick C.; Donahue, Aaron S.; Westerink, Joannes J.; Luettich, Richard A.; Zheng, L. Y.; Weisberg, Robert H.; Huang, Y.; Wang, H. V.; Teng, Y.; Forrest, D. R.; Roland, A.; Haase, A. T.; Kramer, A. W.; Taylor, A. A.; Rhome, J. R.; Feyen, J. C.; Signell, Richard P.; Hanson, J. L.; Hope, M. E.; Estes, R. M.; Dominguez, R. A.; Dunbar, R. P.; Semeraro, L. N.; Westerink, H. J.; Kennedy, A. B.; Smith, J. M.; Powell, M. D.; Cardone, V. J.; Cox, A. T. (John Wiley & Sons, 2013-10-08)
    A Gulf of Mexico performance evaluation and comparison of coastal circulation and wave models was executed through harmonic analyses of tidal simulations, hindcasts of Hurricane Ike (2008) and Rita (2005), and a benchmarking ...
  • Variational analysis of drifter positions and model outputs for the reconstruction of surface currents in the central Adriatic during fall 2002 

    Taillandier, V.; Griffa, A.; Poulain, P. M.; Signell, Richard P.; Chiggiato, Jacopo; Carniel, Sandro (American Geophysical Union, 2008-04-04)
    In this paper we present an application of a variational method for the reconstruction of the velocity field in a coastal flow in the central Adriatic Sea, using in situ data from surface drifters and outputs from the ROMS ...
