| 説明 | NOAA's National Geodetic Survey and Center for Operational Oceanographic Products and Services are collaborating with the National Estuarine Research Reserve System to establish and monitor coastal land elevations in relation to local sea level throughout the reserve system. This marker from the Chesapeake Bay Reserve in Virginia is part of the required spatial framework needed to establish the reserves as 'sentinel' sites for measuring and monitoring the impacts of climate change on estuarine systems. The inscription reads: 'National Oceanic and Atmospheric Administration; National Estuarine Research Reserve System; National Geodetic Survey.'To learn more about estuaries, visit:Explore: National Estuarine Research ReservesNational Estuarine Research Reserve System(Original source: National Ocean Service Image Gallery) |
