Gis analysis of remotely sensed and field observation oceanographic data

The National Oceanic and Atmospheric Administration's Ocean Environment Research Division established a geographic information system (GIS) for integrating multidisciplinary oceanographic data collected throughout the eastern North Pacific Ocean. Data collected by remote‐sensing techniques include satellite imagery of sea surface temperature, seafloor bathymetry derived from multibeam sonar systems, and environmental acoustic signals from bottom‐mounted and portable hydrophone arrays. Acoustic monitoring is directed at the detection and location of water‐borne signals of seafloor earthquakes (T‐waves) and whales. Field observations include seafloor geologic mapping and whale sightings. Seafloor mapping information is gathered using submersibles, towed‐camera systems, and other towed water‐sampling devices. A GIS allows the integration and analysis of these diverse and various spatial data and formats within a single computer architecture accessible through an easy‐to‐use graphical user interface. The GIS ...
