NOAA Hydrographic Survey Spending in Question

The National Oceanic and Atmospheric Administration (NOAA) needs to improve its strategy for analyzing costs and expanding private sector involvement in collecting hydrographic data, says a report from the U.S. Government Accountability Office (GAO).   As one of its many duties, NOAA is tasked with collecting hydrographic data. This data, which is used in helping to create critical nautical charts, is either collected using NOAA’s own fleet of four survey vessels, or acquired through the private sector.   Asked by Congress to review NOAA’s hydrographic data collection efforts
