Research & Development Center Coastal & Hydraulics Lab Huijie Xue - Professor, University of Maine Aijun Zhang - Center for Operational Oceanographic Products and Services, NOS/NOAA

16. COMT 2.0 – Proposed Projects This objective of this proposal is to address the NOAA needs identified in the COMT FFO supplemental information to: (1)improve cyber infrastructure; (2)evolve community standards; (3)assess model and forecast systems; and (4)assess data assimilation techniques.

17. COMT 2.0 – Proposed Projects (i) Chesapeake Bay Ecological Forecasting assess the readiness and maturity of a suite of existing coastal ecological community models for determining past, present and future hypoxia events within the Chesapeake Bay, in an effort to accelerate the transition of hypoxia model formulations from research to Federal operational centers. primary objective of this project is the incorporation of an enhanced dissolved oxygen formulation embedded within an improved version of NOAA’s Chesapeake Bay Operational Forecasting System (CBOFS). The model will be available to the NOAA Center for Operational Oceanographic Products and Services for consideration during their scheduled 2014 replacement of the current version of CBOFS. second objective is to create an invaluable resource to both researchers and managers by archiving results from multi-decadal runs from a suite of state-of-the-art models of the Chesapeake Bay on the COMT server.

18. COMT 2.0 – Proposed Projects (ii) Integration of US West Coast Operational Coastal and Ocean Models goal is to integrate three existing operational models of the coastal and ocean waters of the US West Coast to provide a coordinated super- regional modeling capability that can be used to evaluate important modeling methodologies and implementation details and that can be transitioned to NOAA NOS for pre-operational trials. objectives are to: 1.evaluate data assimilation schemes applied presently with the west coast models; 2.improve data-driven predictions through determination of best lateral boundary conditions; 3.assess the potential for existing coupled biogeochemical-physical models to provide useful ecological forecasts; 4.perform model-model and model-data comparisons for our ocean forecasts using COMT cyber-infrastructure tools and; 5.contribute to development of a testbed for coupled biogeochemical models.

19. COMT 2.0 – Proposed Projects (iii) Puerto Rico/US Virgin Islands Inundation and Wave Forecasting goal is to extend the present wave/surge operational forecasting capability from mild-sloped coastal areas such as the US East and Gulf of Mexico coasts to steep-sloped areas such as around Caribbean and Pacific islands and transition this capability to NOAA’s National Hurricane Center and local WFOs. objectives are to: 1.compile a data set of observations collected around Puerto Rico and the USVI by the IOOS Caribbean Regional Association; 2.evaluate multiple, coupled wave/surge/inundation models against this data; 3.recommend the most suitable model for transition to operations; and 4.assist with the transition.

20. COMT 2.0 – Proposed Projects (iv) Northern Gulf of Mexico Ecological Forecasting goal is to implement and demonstrate a real-time hypoxia forecasting system applicable to the hypoxia-prone Northern Gulf of Mexico. objectives are to carry out an inter comparison of three models: 1.ROMS and its native hypoxia module; 2.FVCOM coupled with the ROMS hypoxia module; and 3.the Navy’s NCOM coupled with the Gulf Ecology Model (GEM). Deliverables will include: 1.demonstration of a seasonal and short-term forecasting system for hypoxia in the northern Gulf of Mexico; 2.pre-operational implementation of the system at NOAA Coastal Survey Development Laboratory (CSDL); 3.Retroactive analyses of forecasts against observations; 4.Hypoxia estimates for scenarios with different river nutrient loads and physical forcing; and 5.Inter-comparison of the three models assessing their ability to simulate hypoxia.

21. COMT 2.0 – Proposed Projects (v) Cyber Infrastructure goal of the cyber infrastructure team is to develop tools to support modeling at operational centers and the broader modeling community and to provide support the four COMT modeling teams. Objectives are 1.server and data management; 2.maintenance of cyber tool kits 3.facilitation of skill assessment and advanced visualization services.

22. COMT 2.0 – Proposed Projects (1)Chesapeake Bay Ecological Forecasting - assess and advance the operational readiness of a suite of existing coastal ecological community models; (2)Integration of US West Coast Operational Coastal and Ocean Models - integrate 3 existing quasi-operational models of the coastal and ocean waters of the US West Coast to provide a coordinated super-regional modeling capability as a precursor to a full West Coast operational forecast system; (3)Puerto Rico/US Virgin Islands Inundation and Wave Forecasting - extend current wave – surge prediction capabilities from mild-sloped coastal areas to steep-sloped, reef-fringed Caribbean islands; (4)Northern Gulf of Mexico Ecological Forecasting - implement and demonstrate a real-time hypoxia forecasting system for the Northern Gulf; and (5)Cyber infrastructure - advance tools available to support operational modeling and to support the four COMT modeling projects.
