Posted: April 30, 2010The oil slick in the Gulf of Mexico has caught the eyes of orbiting satellites, which have collected wide-angle and high-resolution snapshots of the growing catastrophe for analysis by emergency responders.

The National Oceanic and Atmospheric Administration, the government agency leading the scientific response the oil spill, is gathering satellite data from U.S., European, Canadian and Japanese satellites to pinpoint the oil’s precise location, boundaries and movement.
The combination of optical and radar imagery gives scientists and emergency crews precise “shapefiles” that map the dimensions of the enlarging oil slick, which covered nearly 5,000 square miles as of Friday morning.
The shapefiles are plugged into advanced computer models to predict where the oil residue will travel based on winds and ocean currents, according to NOAA.
The models forecast the location of the oil one, two and three days later.
NASA’s Terra and Aqua satellites, Canada’s Radarsat spacecraft, the Japanese Advanced Land Observation Satellite, Germany’s TerraSAR-X radar observer and the French Spot remote sensing platforms have all provided data for the shapefiles, NOAA officials said.

The European Space Agency’s Envisat spacecraft has also turned its camera and radar instrument toward the Gulf Coast.
Satellite imagery is also being used to distinguish between normal marine pollution and the damaging effects directly related to the spill, according to NOAA.
An oil drilling rig off the coast of Louisiana exploded April 20 and sank two days later, sending a stream of crude oil into the Gulf of Mexico. Officials estimate about 210,000 gallons of oil continue leaking from the ocean floor each day.
Parts of the oil slick have already reached the Louisiana coast, and shorelines in Mississippi, Alabama and Florida are at risk over the next few days.
The international fleet of satellites will continue to provide imagery immediately to NOAA and U.S. authorities as the oil spill spreads across a wider swath of the Gulf.

Technology Test Pilot
In 1995 At Maui High Performance Computing Center The Maui Scientific Analysis & Visualization of the Environment Program was first incubated. I was the principal investigator of this independant research project which was a joint development between MHPCC, Silicon Graphics Computers (SGI) & NKO.ORG. Using SGI Cosmo Worlds software, we pioneered the development of Internet based 3D virtual reality GIS based interactive worlds. In 1996 with a network of seven high performance SGI workstations we pioneered development of live streaming MPEG-1, MPEG-2, MPEG-4, Real Video and QuickTime Streaming Server utilizing Kassenna MediaBase software. In Maui 2002 we pioneered and tested the first wireless live streaming video using laptop computers and Maui Sky Fiber's portable 3G wireless device. In Maui we pioneered live streaming video using usb modems from AT&T , Verizon as well as live streaming from iPhone 3 over 3G wireless networks. Today The Maui S.A.V.E. Program has diversified into storm tracking including visualization and analysis of large, memory-intensive gridded data sets such as the National Hurricane Center's wind speed probabilities. I volunteer my services to numerous Disaster Services Organizations. In June 2013 I returned from Hurricane Sandy deployment as a computer operations service associate with the Disaster Services Technology Group assisting as The American Red Cross migrated from a Disaster Response Operation to Long Term Recovery Operations. Pioneering the production/editing and Internet distribution of HD video to sites like Youtube.com and Vimeo.com we are shining the light towards environmental and peace efforts of humans across the globe. Since 1992 I have held the vision of establishing Maui, Hawaii as the environmental sciences center of the world. After His Holiness the 14th Dalai Lama of Tibet came to Maui This vision has expanded to establishing Maui as the environmental & peace center of the world.
