Guam EPSCoR Project Highlighted as an "Impact" News Item by NSF
In Guam, researchers developed a method for mapping underwater areas that is transforming how oceanographers observe the seafloor. Data from global positioning satellites are the primary method for mapping the Earth, but it's impossible for global positioning system (GPS) signals to pass through water, making detailed mapping of underwater features difficult. By synchronizing underwater cameras with GPS buoys and using software to geo-tag photographs, NSF-funded researchers have mapped all of Guam's Pago Bay and Apra Harbor.
