Industry:Earth science
The average interval of time between the upper or lower transit of the full or new Moon and the next low water.
Industry:Earth science
The study of methods for solving geodetic problems on a reference ellipsoid. This is a more general term than spheroidal geodesy.
Industry:Earth science
Originally, a dumpy level having the spirit level mounted on top of a short telescope with a large objective lens. Later, the telescope was mounted on wyes. This is said to be the original dumpy level (a distinction also claimed for the Troughton level.
Industry:Earth science
A gradual rising of the surface in cold weather, caused by the freezing and consequent expansion of water in the soil. Any part of the water table within two meters of the surface has, in cold climates, the potential for causing frost heave.
