National Oceanic and Atmospheric Administration Mapping Surveys

Christian Andreasen

The National Oceanic and Atmospheric Administration (NOAA) multibeam surveys within the U.S. Exclusive Economic Zone (EEZ) are providing a new data base of bathymetric information significantly superior to existing bathymetric maps compiled from prior survey information. Surveys made with the new Sea Beam and Bathymetric Swath Survey System are intended to provide 100% coverage of selected areas of the continental shelf, slope, and upper rise off the west coast of the United States. During the next 2 years, surveys will expand to Hawaii and Alaska. Areas were selected through a cooperative agreement between NOAA and the U.S. Geological Survey (USGS). The intent of the program is to provide detailed bathymetry conducted in conformance with international map standards for u e in making geologic interpretations and assessments in conjunction with the GLORIA image data acquired by USGS. The primary objective of the program is to provide high-resolution data to support the development and management of offshore resources, particularly within the U.S. EEZ. Within NOAA, the data are to be used to provide new and revised map and chart products. Also, to maximize the utility of the surveys, arrangements are being sought to acquire other geophysical measurements and ancillary marine data in conjunction with the bathymetric surveys. Dissemination of the NOAA data is undecided due to national security concerns. However, efforts are underway in cooperation with the Department of Defense to devise a public product of value to scientific and industrial needs without com romising national security.
