27. Many of the oceanic consequences of climate change can best be explored with realistic high- resolution global ocean climate models, like those now being developed at GFDL. Example below: The roles of ocean transport and microbial decay in determining the impacts of the Deepwater Horizon oil spill, explored with a 1/8° global ocean climate model in a collaboration between NOAA/GFDL & NOAA/OR&R.

28. The developer stopped work in December 2008 when NCWCP construction was 80% complete. In May 2009, the developer filed a claim in Federal Court to recover “damages” from the Government. This claim was dismissed without prejudice in August 2010. In October 2010, the developer filed an appeal; resolution of this appeal is pending. In June 2009, the developer filed for bankruptcy with the County Court. In response, the court appointed a “Receiver” to complete the project. In November 2010, the court approved the Receiver’s plan and granted the receiver permission to resume construction. In December 2010, the Receiver petitioned the U.S. Court of Appeals for the Federal Circuit for dismissal of the previous claim filed by Maryland Enterprises. The Federal Court granted the motion on February 9, 2011 and dismissed the claim filed by the developer. These actions cleared away all remaining legal obstacles for the restart of work on the NCWCP project. GSA’s goal is to reach project completion approximately 12 months after re-start of construction. GSA’s most current estimate for the building’s substantial completion is March 2012 with complete move-in by July 2012. 28 New Building Status

29. 29 Summary NCEP is –Strategically aligned with NOAA’s “seamless suite” of products from the “Sun to the Sea” –Continually improving collaborative forecasts – especially for extreme events –Working with NOAA on expanded responsibilities (e.g, oceans air and water quality, ecology, space weather…); success is based on interdisciplinary approach –A critical transition agent in the NOAA “research to operations” process involving observations, data assimilation, modeling, and service delivery –Actively pursuing opportunities for collaboration in research, transition to operations and operational production and delivery of services with national and international communities 29
