The National Data Buoy Center (NDBC) demonstrates Data Management System for the Deep-ocean Assessment and Reporting of Tsunami (DART®) Improved Real-Time Data Management Efforts
Jack Higgs and Jing Zhao, NOAA/NDBC and Science Applications International Corporation (SAIC) visited the National Geophysical Data Center (NGDC) to demonstrate a new (DART®) Data Management System. The DART® Data Management System is a Web-based system to track metadata, and to receive, monitor, validate, and report on DART® data availability and quality status throughout the lifecycle of deployments. The system shows data monitoring and quality control functionality designed to assist both real-time data managers and support the needs of the archive at NGDC. The automated real-time data display of metadata and data, as well as recovered data and metadata will help ensure a quality product for real-time data users, including the Tsunami Warning Centers, researchers serviced through the archive, and any subscribing customers in the field.
Significance: Although infrequent, tsunami waves have caused considerable damage and loss of life in U.S. coastal areas. The DART® network is an essential component in the provision of timely warnings to U.S. coastal communities. DART® data support the NOAA Tsunami Program observation requirements for Tsunami Offshore Real-Time and Post-event observations, as well as Global Water Level Observations, as described in NOAA's Consolidated Observational Requirements List (CORL). In addition, climate change research scientists are interested in the growing archive of DART® data.
Outcome: This activity supports the general goal to improve our environmental and marine infrastructure and to develop a more robust Global Earth Observation System of Systems (GEOSS).

National Geophysical Data Center (NGDC) Briefs at the NOAA Tsunami Program Review
NGDC's Susan McLean attended the NOAA Tsunami Program Review in Seattle, WA on January 21-22, 2009. Line Office representatives from across NOAA delivered briefings to the Program identifying accomplishments in the last two fiscal years and planned deliverables for the next planning cycle (FY09-12). NGDC briefed on the coastal digital elevation modeling (DEM) effort supporting tsunami forecast and warning and on the tsunami data archive and delivery tasks. NGDC will complete the original plan for 75 coastal community DEMs by the second quarter of FY12. Due to the vastly expanded observing network and increases in data resolution, the archive, which has grown more than 300 fold in the last 4 years, is expected to more than quadruple by FY12.
Significance: Although infrequent, tsunami waves have caused considerable damage and loss of life in U.S. coastal areas. The NOAA/NGDC efforts in tsunami data management and its role in developing coastal digital elevation models are essential aspects of the NOAA effort to forecast and mitigate impacts from tsunami events. The integrated hazards archive provides Deep-ocean Assessment and Reporting of Tsunamis (DART®), Tide Gauge, and Historical Event data essential for coastal hazard assessment, improved data for research, and assured access to data related to past hazardous events for monitoring and mitigating the socio-economic impact of coastal hazards.
Outcome: This activity supports the general goal to improve our environmental and marine infrastructure and to develop a more robust Global Earth Observation System of Systems (GEOSS).

National Geophysical Data Center (NGDC) develops ETOPO1 global-relief imagery for NOAA's Science On a Sphere®
NGDC has created a detailed, color, shaded-relief image of its ETOPO1 1 Arc-Minute Global Relief Model of Earth for NOAA's Science On a Sphere®. The imagery was created from the ETOPO1 'Ice Surface' version, with blues representing ocean depths and subaerial lakes, greens and browns depicting topography (including dry areas below sea level), and shades of white for the Antarctic and Greenland ice sheets. The imagery has been embedded into a movie of Earth that can be downloaded from the Science On a Sphere® web site. http://sos.noaa.gov/datasets/Land/etopo1.html.
Significance: NOAA/NGDC develops visualization products of its global, regional and coastal digital elevation models as an integral part of NOAA's effort to educate and engage the public in marine science and natural hazards.
Outcome: This activity supports the general goal to improve our environmental and marine infrastructure and to develop a more robust Global Earth Observation System of Systems (GEOSS).

NOAA's National Geophysical Data Center (NGDC) Initiates Geospatial One-Stop Harvest
NGDC completed publishing 12,281 National Ocean Service (NOS) hydrographic survey metadata with Geospatial One-Stop (GOS), which is an E-Government initiative, part of the National Spatial Data Infrastructure Training Program, and the metadata clearinghouse for the Integrated Ocean and Coastal Mapping program (IOCM). NGDC is the national archive and steward for NOS hydrographic survey data. This is an on-going partnership between NGDC and the NOS Hydrographic Survey Division.
Significance: One common method of data discovery is searching through data and metadata repositories. GOS is one of the E-Government initiatives of the Presidents Management Agenda, which seeks to provide data in a "one stop shop" and is a government, cross-agency initiative, with the primary objectives to provide access to many themes of geospatial data and web mapping services to portray that data. Under the IOCM, all government agencies collecting coastal and ocean data will coordinate efforts and publish metadata in GOS.
Outcome: This activity supports the general goal to improve our environmental and marine infrastructure and to develop a more robust Global Earth Observation System of Systems (GEOSS).

NOAA's National Geophysical Data Center (NGDC) Develops New Tsunami Inundation Digital Elevation Model of Portland, Maine
NGDC has developed a high-resolution coastal digital elevation model (DEM) of Portland, Maine for the Pacific Marine Environmental Laboratory (PMEL). This integrated bathymetric-topographic DEM is part of an on-going collaboration across NOAA to support the tsunami forecast and warning system being developed by PMEL for the Tsunami Warning Centers. The new DEM covers an area roughly 1 degree square centered on Portland, Maine, with a cell size of one-third arc-second (~10 m). It was compiled from the best available digital data obtained from U.S. federal, state and local agencies, and will increase the accuracy with which NOAA's tsunami modeling efforts will forecast inundation in the region.
Significance: Although infrequent, tsunami waves have caused considerable damage and loss of life in U.S. coastal areas. The NOAA/NGDC development of coastal digital elevation models is an integral part of NOAA's effort to forecast tsunamis and deliver accurate and timely warnings and to develop resilient communities. The DEMs and other tsunami data archived by NGDC provide information essential for coastal hazard assessment and research related to past hazardous events for monitoring and mitigating the socio-economic impact of coastal hazards.
Outcome: This activity supports the general goal to improve our environmental and marine infrastructure and to develop a more robust Global Earth Observation System of Systems (GEOSS).
