• The National Geodetic Survey (NGS) officially releases NOAA Technical Report 50: Rates of Vertical Displacement at Benchmarks in the Lower Mississippi Valley and the Northern Gulf Coast. The report describes the methods and results of research into recent rates and spatial distribution of subsidence on benchmarks in the lower Mississippi Valley and northern Gulf Coast region. The technical report underwent extensive review by the academic and scientific communities.
