Our transcription: To accurately map an area of ocean floor using GLORIA technology requires very precise navigation. The longitudes and latitudes of specific sites are determined with the assistance of earth orbiting satellites in communication with the research vessel. This technique is termed "GPS," the "Global Positioning System." Navigation is the most important of all the data we collect. If we can't locate the image or a bit of the image exactly where it is on the surface of the sea floor on the map, then we haven't really done our job. Someone must be able to go back after identifying something on a GLORIA mosaic, go back to that latitude and longitude and find that image piece on the sea floor, so we use global positioning. We use GPS navigation, and it is the one thing that we pay more attention to on board the ship and after the cruise than anything else. It's the cornerstone for everything we do.
