Sea Level Scientist visits the National Geophysical Data Center (NGDC)
Dr. Alexander Rabinovich from the Institute of Ocean Sciences, B.C., Canada, and the Shirshov Institute of Oceanology, Moscow, Russia, visited NGDC and the co-located World Data Center (WDC) from Sept 15-29, 2008. Dr. Rabinovich is an expert in the identification of tsunami signals in sea level data (e.g. tide gauge and deep ocean sensor). He analyzed several important records during his visit and also provided NGDC with the software tools and training necessary to continue this type of data analysis. Several discoveries resulted from this short visit, including the detection of very clear signals from the 2004 Indian Ocean tsunami at the NOAA Deep-ocean Assessment and Reporting of Tsunamis (DART®) stations off the west coast of the U.S. and the confirmation of four tsunamis with sources in the Kuril islands and the South Pacific that were recorded at tide gauge stations in Australia. The analysis revealed several quality-control issues related to transmission of data that have been reported to the responsible institutions. Dr. Rabinovich also presented two talks entitled "Tsunami: Physics, Observations, Analysis and Numerical Modeling" and "The 26 December 2004 Sumatra Tsunami in the World Ocean: Observations and Analysis." Dr. Rabinovich was the 8th WDC Visiting Scientist to visit NGDC this year. The WDC Visiting Scientist Program enables world-class scientists to work with NOAA scientists on specific projects of mutual interest.
Significance: The NOAA/NGDC efforts in data management and its role in archiving NOAA's tsunami and bathymetry data are essential aspects of the NOAA effort to forecast and mitigate impacts from tsunami events. The integrated hazards archive provides 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.
