Scientists investigating wetland soil vertical development have required a high precision, high accuracy technique to measure wetland surface elevation change over time. The Surface Elevation Table (SET), capable of millimeter-scale precision, has proven effective in supporting hypothesis-based inquiry into mechanisms of wetland vertical development. More recently, SET sampling stations have been...
In hydrographic surveying, vertical datum is an important aspect for sounding as it is used as a reference to reduce for the depth of water at any instant. The recorded soundings made in hydrographic surveys must be corrected for any departure from true depth, such as transducer draft and reduction to the vertical datum. The tide reductions were derived from data recorded by tide gauge mounted on...
