Abstract


  • The research underpinning Stoddart and Murphy’s paper ‘Attainable standards of accuracy in the

    determination of Holocene sea-levels in the Central Pacific’ was undertaken in 1990–1993. This was a

    time when topographic survey was on the cusp of moving from traditional ground-based levelling

    surveys, from fixed, sea level-related benchmarks, to methods based on satellite altimetry. The former

    approach required surveys to be related to a well-defined tidal record (as detailed by Stoddart, 1978),

    while the latter effectively removed the need for a local datum by providing a common, global reference

    point, essentially the centre of the earth. As Stoddart and Murphy themselves perceptively noted ‘New

    mobile global positioning systems (GPS) and satellite altimetry surveys hold out the prospect of relatively

    high accuracy surveying even on remote islands’.
