  • BioCast: Bio-Optical Forecasting of Biogeochemical Dispersion | TechLink
    the location of various materials in the ocean including oil spills organics and biological organisms such as phytoplankton and suspended inorganic solids The software runs on a typical laptop computer and operates based on two data inputs 1 Geospatial calculations from ocean circulation models and 2 ocean color data available from satellite or other remote imaging platforms BioCast has been validated by predicting the spread of oil from the Deepwater Horizons spill as well as water clarity for the 2013 Trident Warrior Naval exercise The system provides excellent forecasts for a 24 hour period yields useful predictions out to 96 hours and can be updated as frequently as new data is available The underlying calculations utilize Eulerian mathematics that yield three dimensional material transport weathering transformation and potential changes in buoyancy The Eulerian calculations and the incorporation of mass conservation features lead to a positive definite solution meaning the system is mathematically robust and will not crash due to data inconsistencies Additional Information Journal Article Forecasting the Ocean s Optical Environment Using the BioCast System 2014 Oceanography 27 3 68 79 News Article NRL models Deepwater Horizon oil spill shows capability to forecast water clarity during naval missions Journal Article Simulating Surface Oil Transport During the Deepwater Horizon Oil Spill Experiments with the BioCast System 2014 Ocean Modeling 75 84 99 Benefits Powerful Versatile Efficiently provides 3 D dispersal predictions for virtually any artificial and natural organic inorganic biological chemical and biogeochemical material from ocean physics model data Robust Corrects input data discrepancies and iteratively constrains to continuity to ensure mathematical integrity and prevent numerical instability Broadly Applicable Useful for forecasting the movement of biologicals the impact of weather events and assessing the potential of natural and human caused disasters specific applications include fishing forecasts diving and recreational water quality

  • Grid Retaining Irregular Networks (GRIN): High Fidelity Geospatial Grid Data Compression | TechLink
    at Stennis Space Center has developed GRIN a fast flexible and highly efficient means of compressing geospatial datasets by thinning points while maintaining a high degree of accuracy for the remaining data points The technology removes grid data points in areas of low variability while retaining the most valuable topography bathymetry or other X Y and Z data points For example a plateau may be represented with fewer data points since elevation is relatively constant over an area thus unneeded grid data points can be eliminated Reducing the size of data sets results in smaller files that requires less storage space are easier to transfer enable more frequent data updates and require less computing power to process GRIN is a new algorithm for calculating Right Triangulated Irregular Networks RTINs that preserves the positional integrity of the remaining original grid points GRIN is designed for charting navigation and other high precision applications Data sets have been compressed with greater than ten fold reduction with full accuracy retention of the source data The compression thinning level is customizable by user selected fixed or percentage Z value thresholds Fixed values flatten out areas that vary less than the threshold e g 10m or 10 C and percentage threshold helps the algorithm retain points that are close to zero but would otherwise be removed by the fixed metric GRIN is written primarily in platform independent JAVA and runs quickly on standard workstations Benefits Efficient Data compression of greater than 10x has been achieved Fast A 1025x1025 grid 2 x2 200m resolution can be compressed or re gridded in about 1 minute Customizable User specified thresholds allow control over the desired level of compression High Fidelity The full integrity of the remaining unthinned data points is retained The Opportunity Pending US patent application available for
